“Ugly Yellow Box” bought by private equity firm

Security is BIG business, probably even bigger than storage and with more “sex” appeal and pazzazz! My friends are owners of 2 of the biggest security distributors in town, so I know. I am not much of a security guy, but I reason I write about Bluecoat is that this company has something close to my heart.

In the early 2000, NetApp used to have a separate division that is not storage. They have a product called NetCache, which is a web proxy solution. It was a pretty decent product and one of the competitors we frequently encounter on the field was an “ugly yellow box” called CacheFlow. Whenever we see an “ugly yellow box” in a rack, we will immediately know that it was a CacheFlow box. NetApp competed strongly with Cache Flow, partly because their CEO and founder, Brian NeSmith, as we NetAppians were told, was ex-NetApp. And there was some animosity between Brian and NetApp, up to the point that I recalled NetApp’s CEO then, Dan Warmenhoven, declaring that “NetApp will bury CacheFlow!“, or something of that nature. At that point, in the circa of 2001-2002, CacheFlow was indeed in a bit of a rut as well. They suffered heavy losses and was near bankcruptcy. A old news from Forbes confirmed Brian NeSmith’s near-bankcruptcy adventure.

 

CacheFlow survived the rut, changed their name to Bluecoat Systems, and changed their focus from Internet caching to security. Know why they are know as “Bluecoat”? They are the policemen of the Internet, and policemen are men in blue coats. I found an old article from Network World about their change.  And they decided not to paint their boxes yellow anymore. 😉

 

Eventually, it was CacheFlow who triumphed over NetApp. And the irony was NetApp eventually sold the NetCache unit and its technology to BlueCoat in 2006. And hence, that my account of the history of Bluecoat.

Yesterday, Bluecoat was on the history books again, but for a better reason. A private equity firm, Thoma Bravo, has put in USD$1.3 billion to acquire Bluecoat. News here and here.

Have a happy Sunday 😀

Gartner 3Q2011 WW ECB Disk Storage Market

Just after IDC released their numbers of their worldwide Disk Storage System Tracker (Read my blog) 10 days ago, Gartner released their Worldwide External Controller Based (ECB) Disk Storage Market report for Q3 of 2011.

The storage market remains resilient (for now) and growing 10.4% in terms of revenue, despite the hard economic conditions. The table below shows the top 7 storage vendors and their relation to their Q2 numbers.

 

EMC remained at the top and gained a massive 3.6% jump in market share. Looks like they are firing all cylinders and chugging like an unstoppable steam train. IBM gained 0.1% in second place as its stable of DS8000, XIV and Storewize V7000 is taking shape. Even though IBM has been holding steadily, I still think that their present storage lineup is staggered and lacks that seamless upgrade path for their customers.

NetApp, which I always terms as the “little engine that could”, is slowing down. They were badly hit in the last quarter, delivering lower than expected revenue numbers according to the analysts. Their stock took a tumble too. As quoted by Gartner, “NetApp’s third-quarter results reflect an overdependence on a few large customers, limited geographic coverage in high-growth countries and increased competition from Dell, EMC, HP and IBM in the midrange modular ECB disk array market segment.

I wrote in my recent blog, that NetApp has to start evolving from a pure-play storage vendor into a total storage and data management solution vendor. The recent rumours of NetApp’s interests in Commvault and Quantum should make a lot of sense if NetApp decides to make that move. Come on, NetApp! What are you waiting for?

HP came back strong in this report. They are in 4th place with 10.4% market share and hot on NetApp’s heels. After many months of nonsensical madness – Leo Apotheker firing, trying to ditch the PC business, the killing of WebOS tablet, the very public Oracle-HP spat – things are beginning to settle a bit under their new CEO, Meg Whitman. In a recent HP Discover conference in Vienna, it was reported that the HP storage team is gung-ho of what they have in their arsenal right now. They called it “The 4 Jewels of HP Storage Crown” which includes 3PAR, Ibrix, StoreOnce and LeftHand. They also leap-frogged over HDS and Dell in the recent Gartner Magic Quadrant (See below).

Kudos to HP and team.

HDS seems to be doing well, and so is Dell. But the Gartner numbers tell a different story. HDS, lost market share and now shares 7.8% market share with Dell. Dell, despite its strong marketing on Compellent, could not make up its loss after breaking off with EMC.

Fujitsu and Oracle completes the line up.

My conclusion: HP and IBM are coming back; EMC is well and far ahead of everyone else; NetApp has to evolve; Dell still lacking in enterprise storage savviness despite having good technology; No comments about HDS. 

Cloud Computing and it’s not iCloud

Steve Jobs was great with what he has done, but when it comes to Cloud Computing, Jeff Bezos of Amazon is the one. And I believe the Amazon Web Services (AWS) is bigger than Apple’s iCloud, in this present time and the future. Why do I say that knowing that the Apple fan boys could be using me as target practice? Because I believe what Amazon is doing is the future of Cloud Computing. Jeff Bezos is a true visionary.

One thing we have to note is that we play different roles when it comes to Cloud Computing. There are Cloud Service Providers (CSP) and there are enterprise subscribers. On a personal level, there are CSPs that cater for consumer-level type of services and there are subscribers of this kind as well. The diagram below shows the needs from an enterprise perspective, for both providers and subscribers.

 

Also we recognize Amazon from a less enterprise perspective, and they are probably better known for their engagement at the consumer level. But what Amazon is brewing could already be what Cloud Computing should be and I don’t think Apple iCloud is quite there yet.

Amazon Web Services cater for the enterprise and the IT crowd, providing both Platform-as-a-Service (PaaS) and Infrastructure-as-a-Service (IaaS) through its delectable offerings of the

  • Elastic Compute Cloud (EC2)
  • SimpleDB
  • Simple Storage Service (S3)
  • Elastic Block Store (EBS)
  • Elastic Beanstalk
  • CloudFormation
  • many more

And AWS has been operational and serving enterprise customers for 5-6 years now. Netflix, Zynga, Farmville are some of AWS customers.  This is something Apple iCloud do not have, a Cloud Computing ecosystems for enterprise customers. Apple iCloud do not offer PaaS or IaaS. Perhaps that’s Apple vision not to get into the enterprise, but eventually the world evolve around businesses and businesses are adopting Cloud Computing. Many readers may disagree with what I say now in this paragraph but I will share with you later that even at the consumer level, Amazon is putting right moves in place, probably more so than Apple’s vision. (more about this later).

But the recent announcement of Kindle Fire, their USD$199 Android-based gadget, was to me, the final piece to Amazon’s Phase I jigsaw – the move to conquer the Cloud Computing space. I read somewhere that USD$199 Kindle Fire actually costs about USD$201.XX to manufacture. Apple’s iPad costs USD$499. So Amazon is making a loss for each gadget they sell. So what! It’s no big deal.

Let me share with you this table that will rattle your thinking a little bit. Remember this: Cloud Computing is defined as a “utility”. Cloud Computing is about services, content. 

The table was taken from a recent Wired Magazine article. It featured the interview with Jeff Bezos. Go check out the interview. It’s very refreshing and humbling.

I hope the table is convincing you enough to say that the device or the gadget doesn’t matter. Yes, Apple and Amazon have different visions when it comes to Cloud Computing, but if you take some time to analyze the comparison, Amazon does not lock you into buying expensive (but very good) hardware, unlike Apple.

Take for instance the last point. Apple promotes downloaded media while Amazon uses streamed media. If you think about it, that what Cloud Computing should be because the services and the contents are utility. Amazon is providing services and content as a utility. Apple’s thinking is more old-school, still very much the PC-era type of mentality. You have to download the applications onto your gadget before you can use it.

Even the Amazon Silk browser concept is more revolutionary that Apple’s Safari. The Silk browser splits some of the processing in the Amazon Cloud, taking advantage of the power of the Amazon Cloud to do the processing for the user. Here’s a little video about Amazon Silk browser.

The Apple Safari is still very PC-centric, where most of the Web content has to be downloaded onto the browser to be viewed and processed. No doubt the Amazon Silk also download contents, but some of the processing such as read-ahead, applet-processing functions have been moved to Amazon Cloud. That’s changing our paradigm. That’s Cloud Computing. And iCloud does not have anything like that yet.

Someone once told me that Cloud is about economics. How incredibly true! It is about having the lowest costs to both providers and consumers. It’s about bringing a motherload of contents  that can be delivered to you on the network. Amazon has tons of digital books, music, movies, TV and computing power to sell to you. And they are doing it at a responsible pace, with low margins. With low margins, the barrier of entry is lower, which in turn accelerates the Cloud Computing adoption. And Amazon is very good at that. Heck, they are selling their Kindle Fire at a loss.

Jeff Bezos has stressed that what they are doing is long term, much longer term than most. To me, Jeff Bezos is the better visionary of Cloud Computing. I am sorry but the reality is Steve Jobs wants high margins from the gadgets they sell to you. That is Apple’s vision for you.

Storage must go on a diet

Nowadays, the capacity of the hard disk drives (HDDs) are really big. 3TB is out and 4TB is in the horizon. What’s next?

For small-medium businesses in Malaysia, depending on their data requirements and applications, 3-10TB is pretty sufficient  and with room to grow as well. Therefore, a 6TB requirement can be easily satisfied with 2 x 3TB HDDs.

If I were the customer, why would I buy a storage array, with the software licenses and other stuff that will not only increase my cost of equipment acquisition and data management, it will also increase the complexity of my IT infrastructure? I could just slot HDDs into my existing server, RAID it with RAID-0 (not a good idea but to save costs, most customers would do that) and I have a 6TB volume! It’s cheaper, easier to manage with Windows or Linux, and my system administrator doesn’t have to fuss about lack of storage experience.

And RAID isn’t really keeping up with the tremendous growth of HDD’s capacity as well. In fact, RAID is at risk. RAID (especially RAID 5/6) just cannot continue provide the LUN or volume reliability and data availability because it just takes too damn long to rebuild the volume after the failure of a disk.

Back in the days where HDDs were less than 500GB, RAID-5 would still hold up but after passing the 1TB mark, RAID-6 became more prevalent. But now, that 1TB has ballooned to 3TB and RAID-6 is on shaky ground. What’s next? RAID-7? ZFS has RAID-Z3, triple parity but come on, how many vendors have that? With triple parity or stronger RAID (is there one?), the price of the storage array is going to get too costly.

Experts have been speaking about parity-declustering,  but that’s something that a few vendors have right now. Panasas, founded by one of forefathers of RAID, Garth Gibson, comes to mind. In fact, Garth Gibson and Mark Holland of Cargenie-Mellon University’s Parallel Data Lab (PDL) presented a paper about parity-declustering more than 10 years ago.

Let’s get back to our storage fatty. Yes, our storage is getting fat, obese, rotund or whatever you want to call it. And storage vendors have been pushing a concept in hope that storage administrators and customers can take advantage of it. It is called Storage Optimization or Storage Efficiency.

Here are a few ways you can consider to put your storage on a diet.

  • Compression
  • Thin Provisioning
  • Deduplication
  • Storage Tiering
  • Tapes and SSDs

To me, compression has not taken the storage world by storm. But then again, there aren’t many vendors that tout compression as a feature for storage optimization. Most of them rather prefer to push the darling of data reduction, data deduplication, as the main feature for save more space. Theoretically, data deduplication makes more sense when the data is inactive, and has high occurrence of duplicated data. That is why secondary storage such  as backup deduplication targets like Data Domain, HP StoreOnce, Quantum DXi can publish 20:1 rates and over time, that rate can get even higher.

NetApp also has been pushing their A-SIS data deduplication on primary storage. Yes, it helps with the storage savings in primary but when the need for higher data transfer rates and time to access “manipulated” data (deduped or compressed), it is likely that compression is a better choice for primary, active data.

So who has compression? NetApp ONTAP 8.0.1 has compression now and IBM with its Storewize V7000 started as a compression device. Read about IBM Storewize in my blog here. Dell has Ocarina Networks, which was recently unleashed. I am a big fan of Ocarina Networks and I wrote about the technology in my previous blog. EMC, during the Celerra days of DART has compression but I don’t hear much about it in their VNX. Compression is there, believe me, embedded all the loads of EMC marketing.

Thin Provisioning is now a must-have and standard feature of all storage vendors. What is Thin Provisioning? The diagram below shows you:

In the past, storage systems aren’t so intelligent. You ask for 10TB, you are given 10TB and that 10TB is “deducted” from the storage capacity. That leads to wastage and storage inefficiencies. Today, Thin Provisioning will give you 10TB but storage capacity is consumed as it is being used. The capacity is not pre-allocated as in the past. Thin provisioning is a great diet pill for bloated storage projects. 

Another up and coming feature is storage tiering. Storage tiering, when associated to storage optimization, should include hierarchical storage management (HSM) and tape-out as well. Storage optimization solutions should not offer only in the storage array itself. Storage tiering within the storage array is available with most vendors – IBM EasyTier, EMC FAST2, Dell Fluid Data Management and many others. But what about data being moved out of the storage array? What about reducing the capacity of the data online or near-line? Why not put them offline if there isn’t a need for it?

I term this as Active Archiving, something I learned while I was at EMC. Here’s a look at EMC’s style of Active Archiving:

Active Archiving promotes the concept of data archiving and is not unique only to EMC. Almost all storage vendors, either natively or with 3rd party vendors, can perform fairly efficient data archiving in one way or another. One of the software that I liked (and not unique!) is Quantum Stornext. Here’s a video of how Quantum Stornext helps reduce the fat of the storage.

With the single-copy sharing feature of Quantum Stornext to multiple disparate OSes, there are lesser duplicate files in storage as well.

Tapes have been getting a bad name in the past few years. It has been repositioned and repurposed as an archive medium rather than a backup medium. But tape is the greenest and most powerful storage diet pill around. And we should not be discount tapes because tapes are fighting back. Pretty soon you will be hearing about Linear Tape File System (LTFS). In a nutshell, Linear Tape File System (LTFS) allows you to use the tape almost as if it were a hard disk. You can drag and drop files from your server to the tape, see the list of saved files using a standard operating system directory (no backup software catalog needed), and use point and click to restore. How cool is that!

And Solid State Drives (SSDs) makes sense as well.

There are times that we need IOPS and using spinning drives, we have to set up many disk spindles to achieve the IOPS that we want.  For example, using the diagram below from the godfather of storage, Greg Schulz,

The set of 16 spinning HDD drives on the left can only deliver 3,520 IOPS. The problem is, we have wasted a lot of disk space, as seen in the diagram below. This design, which most customer would be accustomed to, may look cheaper but in actual fact, is NOT.

If the price of a Fibre Channel HDD is RM2,000, the total of 16 would make up RM32,000.00. That is not inclusive of additional power and cooling and rack space and also the data management costs. Assuming the SSDs costs 5 times more than the Fibre Channel HDD. SSDs are capable of delivering very high IOPS. Here I am putting a modest 5,000 IOPS per SSDs. With just 2 SSDs (as the right design suggests), the total costs is only RM20,000. It has greater performance room to grow, and also savings in data management, power and cooling.

Folks, consider SSDs as part of your storage diet plan.

All these features are available, in whole or in part, and they are part of the storage technology offerings that is out there. With all these being said, are you doing something about it? Get off your lazy bum and start managing your storage and put your storage on a diet!!!

Hated GUI killing Ubuntu

OK, this is off-topic. Not my usual storage news but I thought I share this with you.

I am a Linux enthusiast. I play around with Linux – mostly Fedora and RedHat flavoured distros. For the past 2 years, one of the things I hated was the rise of Ubuntu. I don’t know why, but I just didn’t like the distro. Ubuntu, based on Debian, was the darling of the Linux desktop world. Perhaps I am a server guy but I just didn’t like Ubuntu. A few years ago, I won a Dell Latitude 2100 with Ubuntu pre-installed. I played around it with for a few days (hated it) and I decided to switch to Fedora 13 after that.

So, as Ubuntu’s star waned, I was piqued by the news. According to DistroWatch, which tracks popular Linux distros based on hits-per-day, Ubuntu is steadily on the decline. Here’s a look at the latest DistroWatch numbers of the top-10 Linux distros:

The decline is likely caused by Ubuntu Unity GUI, which replaced the likable GNOME/KDE interface in Ubuntu Natty Narwhal 11.04 version. The current version, Oneiric Ocelot 11.10, is taking a lot of hits of the wrong kind. It has dropped from the top spot and now down to #4.

Here’s a few screenshots of the Unity interface in Natty Narwhal.

 

I am pleasantly surprised that a GUI interface could cause so much harm to a Linux distro but judging by the number of haters out there, I guess the Unity GUI is killing Ubuntu’s popularity. Let’s see how Ubuntu will react in its version 12.04, Precise Pangolin.

The top distro is now Linux Mint, another Debian derivative. I have not tried Linux but I have been playing around with OpenSuSE 12.1. Not bad, buggy, but not bad.

I am still waiting to start my Fedora 16 download – 3.2GB baby over the Jaring SOMAport link. One day, but not today!

One-stop shop matters

Would you buy fruits from dedicated fruit seller or would you go to a hypermarket to get your fruits? It depends on your preference but it is more likely that you would go to a hypermarket to do your shopping. You might need some accompanying stuff while you are at the hypermarket. There will be ideas stirring in your mind that you might need this or that while planning your fruit shopping.

The “ideas stirring in your mind” is what concepts like hypermarkets do. They mess around with your thinking and they play with your psychological side because we are human beings. We are driven by desire and convenience.

In storage, this whole psychological game comes into play as well in the customer’s purchasing habits. If the customer is purchasing storage from one vendor, he/she might as well get the rest of the data management solutions from the same vendor. The vendors would pitch easy, cost-effective, seamless, proven and other well-received words to woo the customer. And the key ingredient is INTEGRATION.

All solutions these days are complex, and integration of getting all components to work together is not easy. I have been working on a private cloud data appliance for almost 2 months now, and it’s not as seamless or as easy as it seems. According to the whitepaper, everything was rosy and dandy but when it comes down to ground zero, even the vendors themselves had a hard time doing the integration. And this drives up costs, resources and time.

That is why EMC has become a behemoth in the storage industry, being an A-Z one-stop shop of everything of data storage and management to every one. That is why IBM and HP are able to leverage their server business and their other solutions and services portfolio to entice the customers to buy their products. That is why Oracle wants to worn the whole bloody application stack in their Exadata, to sell more Oracle database licenses. Pure-play storage vendors like NetApp and HDS, who prefer to work on partnership could be feeling the heat of late.

In the latest IDC quarter worldwide disk storage system tracker (that’s a mouthful), NetApp is the prominent one being mentioned as “losing ground“. Here’s a look at a table, which compares past quarters results.

It is difficult to quantify integration costs, because there are many intangible, and unseen costs and impacts. To pacify customer’s fears, and increase their confidence in the total data storage and management solutions, marketing initiatives such as whitepapers, reference architectures, webcasts, social media, social business networking, demos, proof-of-concepts (POCs) and many more are tools of the trade that could tip a customer towards a vendor’s solution.

I believe NetApp could begin to realize that. And rumours are swirling in the industry for NetApp to acquire strong solutions such as Commvault and Quantum. It makes sense. NetApp is in need of a strong data protection solution in which it has a say in the vision and direction of the software. NetApp needs a strong data deduplication solution in which Quantum has in its DXi series. Symantec could be a acquisition target as well as the security and data management giant’s stock has stagnated in the stock market.

NetApp itself could be an acquisition target as well, with IBM, Cisco and HP the possible suitors. NetApp’s solutions are a great solution set for IBM, who really needs to do something about their staggered storage portfolio. HP might have chewed a mouthful with 3PAR but HP has been bad news for the last 2 quarters, no thanks to its on-and-off fiasco of ditching it PC business and other crazy stunts of HP-versus-Oracle and their ex-CEO, Leo Apotheker. Cisco could bet on NetApp too. Both companies have strong relationship together, but Cisco is drying up. They are becoming a laggard in the networking industry and companies like Juniper are hitting back … hard!

All these jousting and shuffling are creating the consolidation of the storage industry. The top six players – EMC, NetApp, IBM, HP, HDS and Dell – owns more than 80% of the total storage market share in terms of revenue. As the data storage and management world becomes more complex, and the ubiquity of cloud computing demands absolute uptime with no room for errors, the one-stop shop makes sense. One throat to choke … as they say.

Magic on storage players

It’s that time of the year again where Gartner releases it Magic Quadrant for the block-access, external controller-based, mid-range and high-end modular disk arrays market. This particular is very important because it represents the mainstay of the overall storage industry, viewed from a more qualitative angle. Whereas the other charts and reports work with statistics and numbers, this is the chart that everyone in the industry flock to. Gartner Magic Quadrant (MQ) is the storage industry indicator of who’s are the leaders; who are the visionaries; who are the executive wizards and who are the laggards (also known as niche players).

So, this time around, who’s in the Leaders Quadrant?

The perennial players in the Leader’s Quadrant are EMC, IBM, NetApp, HP, Dell, and HDS. In my previous blog, I shared with you the IDC figures about market shares but the Gartner MQ shows are more subtle side, and one that perhaps carry more weight to organizations.

From the IDC numbers announced previously, we have seen Dell taking a beating. They have lost market share and similarly in this latest Gartner MQ, they have lost their significance of their influence as well. Everyone expected their Compellent solution to be robust and having EqualLogic, Ocarina and Exanet in its stable would strengthen their presence in the storage industry. Surprisingly, Dell lost on both IDC statistically charged market numbers and this Gartner MQ as well. Perhaps they were too hasty to dump EMC a few months ago?

Gartner also reported that HP has made significant leap in the Leader’s Quadrant. It has leapfrogged over HDS and IBM when comparing their position in Gartner’s MQ chart. This could be coming from their concerted effort to pitch their Converged Infrastructure, a vision that in my opinion, simplified computing. HP Malaysia shared with me their vision a few months ago, and I was impressed. What I was not very impressed then and even now, is that their storage solutions story is still staggered, lacking the gel. Perhaps it is work in progress for HP, the 3PAR, the IBRIX and the EVA. But one things for sure. They are slowly but surely getting the StoreOnce story right and that’s good news for customers. I did a review of HP StoreOnce technology a few months ago.

Perhaps it’s time for HP to ditch their VLS deduplication, which to me, confuses customers. By the way, HP VLS is an OEM from Sepaton. (Sepaton is “No tapes” spelled backwards)

Here’s a glimpse of last year’s Magic Quadrant.

 

In the Niche Quadrant, there are a few players making waves as well. 2 companies to watch out for are Huawei (they dropped Symantec 2 weeks ago) and Nexsan. Nexsan has been beefing up its marketing of late, and I often see them in mailing lists and ads on some websites I went to.

But the one to watch will be Huawei. This is a company with deep pockets, hiring the best in the storage industry and also has a very strong domestic market in China. In the next 2-3 years, Huawei could emerge as a strong contender to the big boys. So watch out!

Gartner Magic Quadrant is indeed weaving its magic and this time around the magic is good to HP.

Crisis? What crisis?

The storage train is still chugging hard and fast as IDC just released its Worldwide Disk Storage System Tracker for 3Q11. Despite the economic climate, the storage market posted a strong 8.5% revenue growth and a whopping 30.7% growth in terms of petabytes shipped. In total, 5,429PB were shipped in Q3.

So how did everyone do in this latest Tracker report?

In the Worldwide Total External Disk Storage Systems, EMC is still holding on to the #1 position, with 28.6%. IBM and NetApp came in at 12.7% and 12.1% respectively. The table below summarizes the percentage view of the top storage players, in terms of revenue.

 

From the table, everyone benefited from the strong buying of storage in the last quarter. EMC gained a strong market gain of almost 3%, while everyone else either gained or lost less than 1% market share.  But the more interesting numbers are not from the market share column but the % growth column.

HDS posted the strongest growth of 22.1%, slightly higher than EMC of 22.0%. HDS is beginning to get their story right, putting the right storage solutions in place, and has been strongly focused in their services offering as well. That’s simply great news for HDS because this is a company is not known for their marketing and advertising. The Japanese “culture” within HDS probably has taught it to be prudent but to see HDS growing faster than the big boys like IBM and HP is something their competitors should respect. I believe customers are beginning to see the true potential of HDS.

As for EMC, everyone labels them as the 800-pound gorilla but they have been very nimble and strong in the storage market for many quarters. This is due to the strong management team headed by Joe Tucci and his heir-in-waiting, Pat Gelsinger. Several of their acquisitions are doing well, with the likes of Isilon, Greenplum, Data Domain, and of course VMware. Even though VMware does not contribute the EMC revenue numbers, the very fact that EMC owns more than 80% of VMware has already given EMC a lot of credibility in the storage battlefield. They are certainly going great guns.

NetApp took a hit in the last quarter, when they missed the street revenue numbers last quarter. Their stock took a beating and there were rumours in the market that NetApp might acquire Commvault and Quantum to compete with EMC. EMC has been able to leverage the list of companies and acquired solutions very well, from data protection solutions like Networker and Avamar, deduplication solutions like Data Domain and Avamar, Documentum for content management and so on, while NetApp has been, for the longest time, prefer a more “loosely-coupled” approach with their partners for a more complete solution set.

Other interesting reports from IDC are the Open SAN/NAS market, the NAS market and the iSCSI market.

The Open SAN/NAS market combination, according to IDC goes like this:

EMC 31.3%
NetApp 14.4%

In the NAS only market, EMC and Isilon (under the one EMC umbrella) competes with NetApp and the table is like this:

EMC 46.7%
NetApp 30.7%

The iSCSI only market is led by Dell (EqualLogic and Compellent combined), followed by EMC and IBM. Here’s the summarized table:

Dell 30.3%
EMC 19.2%
IBM 14.0%

The strong growth is indeed good news as the storage market continues to weather the economic crisis storm. I have been saying this all along. The storage market in IT is still the growth engine as data keeps growing and growing, even though it was never the darling of the IT industry. Let’s hope the trend continues.

Betcha don’t encrypt your disks

At the Internet Alliance event this morning, someone from Computerworld gave me a copy of their latest issue. The headline was “Security Incidents Soar”, with the details of the half-year review by CyberSecurity Malaysia.

Typically, the usual incidents list evolve around spam, intrusions, frauds, viruses and so on. However, storage always seems to be missing. As I see it, storage security doesn’t sit well with the security guys. In fact, storage is never the sexy thing and it is usually the IPS, IDS, anti-virus and firewall that get the highlights. So, when we talk about storage security, there is so little to talk about. In fact, in my almost 20-years of experience, storage security was only brought up ONCE!

In security, the most valuable piece of asset is data and no matter where the data goes, it always lands on …. STORAGE! That is why storage security could be one of the most overlooked piece in security. Fortunately, SNIA already has this covered. In SNIA’s Solid State Storage Initiative (SSSI), one aspect that was worked on was Self Encrypted Drives (SED).

SED is not new. As early as 2007, Seagate already marketed encrypted hard disk drives. In 2009, Seagate introduced enterprise-level encrypted hard disk drives. And not surprisingly, other manufacturers followed. Today, Hitachi, Toshiba, Samsung, and Western Digital have encrypted hard disk drives.

But there were prohibitive factors that dampened the adoption of self-encrypted drives. First of all, it was the costs. It was expensive a few years ago. There was (and still is) a lack of knowledge between the hardware of Self Encrypted Drives (SED) and software-based encryption. As the SED were manufactured, some had proprietary implementations that did not do their part to promote the adoption of SEDs.

As data travels from one infrastructure to another, data encryption can be implemented at different points. As the diagram below shows,

 

encryption can be put in place at the software level, the OS level, at the HBA, the network itself. It can also happen at the switch (network or fabric), at the storage array controller or at the hard disk level.

EMC multipathing software, PowerPath, has an encryption facility to ensure that data is encryption on its way from the HBA to the EMC CLARiiON storage controllers.

The “bump-in-the-wire” appliance is a bridge device that helps in composing encryption to the data before it reaches the storage. Recall that NetApp had a FIPS 140 certified product called Decru DataFort, which basically encrypted NAS and SAN traffic en-route to the NetApp FAS storage array.

And according to SNIA SSSI member, Tom Coughlin, SED makes more sense that software-based security. How does SED work?

First of all, SED works with 2 main keys:

  • Authentication Key (AK)
  • Drive Encryption Key (DEK)

The DEK is the most important component, because it is a symmetric key that encrypts and decrypts data on the HDDs or SSDs. This DEK is not for any Tom (sorry Tom), Dick and Harry. In order to gain access to DEK, one has to be authenticated and the authentication is completed by having the right authentication key (AK). Usually the AK is based on a 128/26-bit AES or DES and DEK is of a higher bit range. The diagram below shows the AK and DEK in action:

Because SED occurs at the drive level, it is significantly simpler to implement, with lower costs as well. For software-based encryption, one has to set up some form of security architecture. IPSec comes to mind. This is not only more complex, but also more costly to implement as well. Since it is software, the degree of security compromise is higher, meaning, the security model is less secure when compared to SED. The DEK of the SED does not leave the array, and if the DEK is implemented within the disk enclosure or the security module of SoC (System-on-Chip), this makes even more secure that software-based encryption. Also, the DEK is away from the CPU and memory, thus removing these components as a potential attack vendor that could compromise the data on the disks drives.

Furthermore, software-based encryption takes up CPU cycles, thus slows down the overall performance. In the Tom Coughlin study, based on both SSDs and HDDs, the performance of SED outperforms software-based encryption every time. Here’s a table from that study:

Another security concern is about data erasure. According to an old IBM study, about 90% of the retired HDDs still has data that is readable. That means that data erasure techniques used are either not implemented properly or simply not good enough. For us in the storage industry, an effective but time consuming technique is to overwrite the entire disks with 1s and reusing it. But to hackers, there are ways to “undelete” these bits and make the data readable again.

SED provides crypto erasure that is both effective and very quick. Since the data encryption key (DEK) was used to encrypt and decrypt data, the DEK can be changed and renewed in split seconds, making the content of the disk drive unreadable. The diagram below shows how crypto erasure works:

Data security is already at its highest alert and SEDs are going to be a key component in the IT infrastructure. The open and common standards are coming together, thanks to efforts to many bodies including SNIA. At the same time, product certifications are coming up and more importantly, the price of SED has come to the level that it is almost on par with normal, non-encrypted drives.

Hackers and data thieves are getting smarter all the time and yet, the security of the most important place of where the data rest is the least considered. SNIA and other bodies hope to create more awareness and seek greater adoption of self encrypted drives. We hope you will help spread the word too. Betcha thinking twice now about encrypting your data  on your disk drives now.
