It’s another quarter and both Gartner and IDC reports on disk storage market are out.
What does it take to slow down EMC, who is like a behemoth beast mowing down its competition? EMC, has again tops both the charts. IDC Worldwide Disk Storage Tracker for Q1 of 2012 puts EMC at 29.0% of the market share, followed by NetApp at 14.1%, and IBM at 11.4%. In fourth place is HP with 10.2% and HDS is placed fifth with 9.4%.
In the Gartner report, EMC has the lead of 32.5%, followed by NetApp at 12.7% and IBM with 11.0%. HDS held fourth place at 9.5% and HP is fifth with 9.0%. Continue reading →
It is kind of interesting when every vendor out there claims that they are as open as they can be but the very reality is, the competitive nature of the game is really forcing storage vendors to speak open, but their actions are certainly not.
Confused? I am beginning to see a trend … a trend that is forcing customers to be locked-in with a certain storage vendor. I am beginning to feel that customers are given lesser choices, especially when the brand of the server they select for their applications will have implications on the brand of storage they will be locked in into.
And surprise, surprise, SSDs are the pawns of this new cloak-and-dagger game. How? Well, I have been observing this for quite a while now, and when HP announced their SMART portfolio for their storage, it’s time for me to say something.
In the announcement, it was reported that HP is coming out with its 8th generation ProLiant servers. As quoted:
“The eighth generation ProLiant is turbo-charging its storage with a Smart Array containing solid state drives and Smart Caching.”
“It also includes two Smart storage items: the Smart Array controllers and Smart Caching, which both feature solid state storage to solve the disk I/O bottleneck problem, as well as Smart Data Services software to use this hardware”
From the outside, analysts are claiming this is a reaction to the recent EMC VFCache product. (I blogged about it here) and HP was there to put the EMC VFcache solution as a first generation product, lacking the smarts (pun intended) of what the HP products have to offer. You can read about its performance prowess in the HP Connect blog.
The idea is very obvious. Put in a PCIe-based flash caching card in the server, and use a condescending caching/tiering technology that ties the server to a certain brand of storage. Only with this card, that (incidentally) works only with this brand of servers, will you, Mr. Customer, be able to take advantage of the performance power of this brand of storage. Does that sound open to you?
HP is doing it with its ProLiant servers; Dell is doing it with its ExpressFlash; EMC’s VFCache, while not advocating any brand of servers, is doing it because VFCache works only with EMC storage. We have seen Oracle doing it with Oracle ExaData. Oracle Enterprise database works best with Oracle’s own storage and the intelligence is in its SmartScan layer, a proprietary technology that works exclusively with the storage layer in the Exadata. Hitachi Japan, with its Hitachi servers (yes, Hitachi servers that we rarely see in Malaysia), already has such a technology since the last 2 years. I wouldn’t be surprised that IBM and Fujitsu already have something in store (or probably I missed the announcement).
NetApp has been slow in the game, but we hope to see them coming out with their own server-based caching products soon. More pure play storage are already singing the tune of SSDs (though not necessarily server-based).
The trend is obviously too, because the messaging is almost always about storage performance.
Yes, I totally agree that storage (any storage) has a performance bottleneck, especially when it comes to IOPS, response time and throughput. And every storage vendor is claiming SSDs, in one form or another, is the knight in shining armour, ready to rid the world of lousy storage performance. Well, SSDs are not the panacea of storage performance headaches because while they solve some performance issues, they introduce new ones somewhere else.
But it is becoming an excuse to introduce storage vendor lock-in, and how has the customers responded this new “concept”? Things are fairly new right now, but I would always advise customers to find out and ask questions.
Cloud storage for no vendor lock-in? Going to the cloud also has cloud service provider lock-in as well, but that’s another story.
The Gartner Worldwide External Controller Based Disk Storage market numbers were out last night, and perennially follows IDC Disk Storage System Tracker.
The numbers posted little surprise, after a topsy-turvy year for vendors like IBM, HP and especially NetApp. Overall, the positions did not change much, but we can see that the 3 vendors I mentioned are facing very challenging waters ahead. Here’s a look at the overall 2011 numbers:
EMC is unstoppable, and gaining 3.6% market share and IBM lost 0.2% market share despite having strong sales with their XIV and StorWize V7000 solutions. This could be due to the lower than expected numbers from their jaded DS-series. IBM needs to ramp up.
HP stayed stagnant, even though their 3PAR numbers have been growing well. They were hit by poor numbers from the EVA (now renumbered as P6000s), and surprisingly their P4000s as well. Looks like they are short-lefthanded (pun intended) and given the C-level upheavals it went through in the past year, things are not looking good for HP.
Meanwhile, Dell is unable to shake off their EMC divorce alimony, losing 0.8% market share. We know that Dell has been pushing very, very hard with their Compellent, EqualLogic, and other technologies they acquired, but somehow things are not working as well yet.
HDS has been the one to watch, with its revenue numbers growing in double digits like NetApp and EMC. Their market share gain was 0.6%, which is very good for HDS standards. NetApp gained 0.8% market share but they seem vulnerable after 2 poor quarters.
The 4th quarter for 2011 numbers are shown below:
I did not blog about IDC QView numbers, which reports the storage software market share but just to give this entry a bit of perspective from a software point of view. From the charts of The Register, EMC has been gaining marketshare at the expense of the rest of the competitors like Symantec, IBM and NetApp.
Tabulated differently, here’s another set of data:
On all fronts, EMC is firing all cylinders. Like a well-oiled V12 engine, EMC is going at it with so much momentum right now. Who is going to stop EMC?
Ok, let me clear the air about the word “Chink” (before I get into trouble), which is not racially offensive unlike the news about ESPN having to fire 2 of their employees for using the word “Chink” on Jeremy Lin. According to my dictionary (Collins COBUILD), chink is a very narrow crack or opening on a surface and I don’t really know the derogatory meaning of “chink” other than the one in my dictionary.
I have been doing a spot of work for a friend who has just recently proposed NetApp MetroCluster. When I was at NetApp many years ago, I did not have a chance to get to know more about the solution, but I do know of its capability. After 6 years away, coming back to do a bit of NetApp was fun for me, because I was always very comfortable with the NetApp technology. But NetApp MetroCluster, and in this opportunity, NetApp Fabric MetroCluster presented me an opportunity to get closer to the technology.
I have no doubt in my mind, this is one of the highest available storage solutions in the market, and NetApp is not modest about beating its own drums. It touts “No SPOF (Single Point of Failure“, and rightly so, because it has put in all the right plugs for all the points that can fail.
NetApp Fabric MetroCluster is a continuous availability solution that stretches over 100km. It is basically a NetApp Cluster with mirrored storage but with half of its infrastructure mirror being linked very far apart, over Fibre Channel components and dark fiber. Here’s a diagram of how NetApp Fabric Metrocluster works for a VMware FT (Fault Tolerant) environment.
There’s a lot of simplicity in the design, because when I started explaining it to the prospect, I was amazed how easy it was to articulate about it, without all the fancy technical jargons or fuzz. I just said … “imagine a typical cluster, with an interconnect heartbeat, and the storage are mirrored. Then imagine the 2 halves are being pulled very far apart … That’s NetApp Fabric MetroCluster”. It was simply blissful.
But then there were a lot of FUDs (fear, uncertainty, doubt) thrown in by the competitor, feeding the prospect with plenty of ammunition. Yes, I agree with some of the limitations, such as no SATA support for now. But then again, there is no perfect storage solution. In fact, Chris Mellor of The Register wrote about God’s box, the perfect storage, but to get to that level, be prepared to spend lots and lots of money! Furthermore, once you fix one limitation or bottleneck in one part of the storage, it introduces a few more challenges here and there. It’s never ending!
Side note: The conversation triggered the team to check with NetApp for SATA support in Fabric MetroCluster. Yes, it is already supported in ONTAP 8.1 and the present version is 8.1RC3. Yes, SATA support will be here soon.
More FUDs as we went along and when I was doing my research, some HP storage guys on the web were hitting at NetApp MetroCluster. Poor HP! If you do a search of NetApp MetroCluster, I am sure you will come across these 2 HP blogs in 2010, deriding the MetroCluster solution. Check out this and the followup on the first blog. What these guys chose to do was to break the MetroCluster apart into 2 single controllers after a network failure, and attack it from that level.
Yes, when you break up the halves, it is basically a NetApp system with several single point of failure (SPOF). But then again, who isn’t? Almost every vendor’s storage will have some SPOFs when you break the mirror.
Well, I can tell you is, the weakness of NetApp MetroCluster is, it’s not continuous data protection (CDP). Once your applications have written garbage on one volume, the garbage is reflected on the mirrored volume. You can’t roll back and you live with the data corruption. That is why storage vendors, including NetApp, offer snapshots – point-in-time copies where you can roll back to the point before the data corruption occurred. That is why CDP gives the complete granularity of recovery in every write I/O and that’s something NetApp does not have. That’s NetApp’s MetroCluster weakness.
But CDP is aimed towards data recovery, NOT data availability. It is focused on customers’ whose requirements are ability to get the data back to some usable state or form after the event of a disaster (big or small), while the MetroCluster solution is focused on having the data available all the time. They are 2 different set of requirements. So, it depends on what the customer’s requirement is.
Then again, come to think of it, NetApp has no CDP technology of their own … isn’t it?
I have been an avid reader of SearchStorage Storage magazine for many years now and have been downloading their free PDF copy every month. Quietly snugged at the end of January 2012’s issue, there it was, the Storage magazine 6th annual Quality Awards for NAS.
I was pleasantly surprised with the results because in the previous annual awards, it would dominated by NetApp and EMC but this time around, a dark horse has emerged. It is Oracle who took top honours in both the Enterprise and the Mid-range categories.
The awards are the result of Storage Magazine’s survey and below is an excerpt about the survey:
In both categories covering the Enterprise and the Mid-Range, the overall ratings are shown below:
Surprised? You bet because I was.
The survey does not focus on speeds and feeds or comparing scalability or performance. Rather, the survey focuses on the qualitative aspects of the NAS products. There were many storage vendors who were part of the participation lists but many did not qualify to be make a dent of what the top 6 did. Here’s a list of the vendors surveyed:
The qualitative aspects of the survey focused on 5 main areas:
Sales force competency
Initial Quality
Product Features
Product Reliability
Technical Support
In each of the 5 main areas, customers were asked a series of questions. Here is a breakdown of those questions of each area.
Sales Force Competency
Are the sales force knowledgeable about their products and their customer’s industries?
How flexible are their sales effort?
How good are they keeping the customer’s interest levels up?
Initial Product Quality
Does the product need little or no vendor intervention?
Ease of installation and ease of use
Good value for money
Reasonable requirement from Professional Service or needing little Professional Service
Installation without defects
Getting it right the first time
Product Features
Storage management features
Mirroring features
Capacity scaling features
Interoperable with other vendor’s products
Remote replication features
Snapshotting features
Product Reliability
Vendor provide comprehensive upgrading procedures
Ability to meet Service Level Agreement (SLA)
Experiences very little downtime
Patches applied non-disruptively
Technical Support
Taking ownership of the customer’s problem
Timely problem resolution and technical advice
Documentation
Vendor supplies support contractually as specified
Vendor’s 3rd party partners are knowledgeable
Vendor provide adequate training
These are some of the intangibles that customers are looking for when they qualify the NAS solutions from vendors. And the surprising was Oracle just became something to be reckoned with, backed by the strong legacy of customer-centric focus of Sun and StorageTek. If this is truly happening in the US, then kudos to Oracle for maximizing the Sun-Storagetek enterprise genes to put their NAS products to be best-of-breed.
However, on the local front, it seems to me that Oracle isn’t doing much justice to the human potential they have inherited from Sun. A little bird has told me that they got rid of some good customer service people in Malaysia and Singapore just last month and more could be on the way in 2012. All this for the sake of meeting some silly key performance indices (KPIs) of being measured by tasks per day.
The Sun people that I know here in Malaysia and Singapore are gurus who has gone through the fire and thrived and there is no substitute for quality. Unfortunately, in Oracle, it’s all about numbers, whether it is sales or tasks per day.
Well, back to the survey. And of course, the final question would be, “Is the product good enough that you would buy it again?” And the results are …
Good for Oracle in the US but the results do not fully reflect what’s on the ground here in Malaysia, which is more likely dominated by NetApp, HP, EMC and IBM.
I am a bit surprised that primary storage deduplication has not taken off in a big way, unlike the times when the buzz of deduplication first came into being about 4 years ago.
When the first deduplication solutions first came out, it was particularly aimed at the backup data space. It is now more popularly known as secondary data deduplication, the technology has reduced the inefficiencies of backup and helped sparked the frenzy of adulation of companies like Data Domain, Exagrid, Sepaton and Quantum a few years ago. The software vendors were not left out either. Symantec, Commvault, and everyone else in town had data deduplication for backup and archiving.
It was no surprise that EMC battled NetApp and finally won the rights to acquire Data Domain for USD$2.4 billion in 2009. Today, in my opinion, the landscape of secondary data deduplication has pretty much settled and matured. Practically everyone has some sort of secondary data deduplication technology or solution in place.
But then the talk of primary data deduplication hardly cause a ripple when compared a few years ago, especially here in Malaysia. Yeah, the IT crowd is pretty fickle that way because most tend to follow the trend of the moment. Last year was Cloud Computing and now the big buzz word is Big Data.
We are here to look at technologies to solve problems, folks, and primary data deduplication technology solutions should be considered in any IT planning. And it is our job as storage networking professionals to continue to advise customers about what is relevant to their business and addressing their pain points.
I get a bit cheesed off that companies like EMC, or HDS continue to spend their marketing dollars on hyping the trends of the moment rather than using some of their funds to promote good technologies such as primary data deduplication that solve real life problems. The same goes for most IT magazines, publications and other communications mediums, rarely giving space to technologies that solves problems on the ground, and just harping on hypes, fuzz and buzz. It gets a bit too ordinary (and mundane) when they are trying too hard to be extraordinary because everyone is basically talking about the same freaking thing at the same time, over and over again. (Hmmm … I think I am speaking off topic now .. I better shut up!)
We are facing an avalanche of data. The other day, the CEO of Nexenta used the word “data tsunami” but whatever terms used do not matter. There is too much data. Secondary data deduplication solved one part of the problem and now it’s time to talk about the other part, which is data in primary storage, hence primary data deduplication.
What is out there? Who’s doing what in term of primary data deduplication?
NetApp has their A-SIS (now NetApp Dedupe) for years and they are good in my books. They talk to customers about the benefits of deduplication on their FAS filers. (Side note: I am seeing more benefits of using data compression in primary storage but I am not going to there in this entry). EMC has primary data deduplication in their Celerra years ago but they hardly talk much about it. It’s on their VNX as well but again, nobody in EMC ever speak about their primary deduplication feature.
I have always loved Ocarina Networks ECO technology and Dell don’t give much hoot about Ocarina since the acquisition in 2010. The technology surfaced a few months ago in Dell DX6000G Storage Compression Node for its Object Storage Platform, but then again, all Dell talks about is their Fluid Data Architecture from the Compellent division. Hey Dell, you guys are so one-dimensional! Ocarina is a wonderful gem in their jewel case, and yet all their storage guys talk about are Compellent and EqualLogic.
Moving on … I ought to knock Oracle on the head too. ZFS has great data deduplication technology that is meant for primary data and a couple of years back, Greenbytes took that and made a solution out of it. I don’t follow what Greenbytes is doing nowadays but I do hope that the big wave of primary data deduplication will rise for companies such as Greenbytes to take off in a big way. No thanks to Oracle for ignoring another gem in ZFS and wasting their resources on pre-sales (in Malaysia) and partners (in Malaysia) that hardly know much about the immense power of ZFS.
But an unexpected source coming from Microsoft could help trigger greater interest in primary data deduplication. I have just read that the next version of Windows Server OS will have primary data deduplication integrated into NTFS. The feature will be available in Windows 8 and the architectural view is shown below:
The primary data deduplication in NTFS will be a feature add-on for Windows Server users. It is implemented as a filter driver on a per volume basis, with each volume a complete, self describing unit. It is cluster aware, and fully crash consistent on all operations.
The technology is Microsoft’s own technology, built from scratch and will be working to position Hyper-V as an strong enterprise choice in its battle for the server virtualization space with VMware. Mind you, VMware already has a big, big lead and this is just something that Microsoft must do-or-die to keep Hyper-V playing catch-up. Otherwise, the gap between Microsoft and VMware in the server virtualization space will be even greater.
I don’t have the full details of this but I read that the NTFS primary deduplication chunk sizes will be between 32KB to 128KB and it will be post-processing.
With Microsoft introducing their technology soon, I hope primary data deduplication will get some deserving accolades because I think most companies are really not doing justice to the great technologies that they have in their jewel cases. And I hope Microsoft, with all its marketing savviness and adeptness, will do some justice to a technology that solves real life’s data problems.
I bid you good luck – Primary Data Deduplication! You deserved better.
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.
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.
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!!!
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.
