Don’t get too drunk on Hyper Converged

I hate the fact that I am bursting the big bubble brewing about Hyper Convergence (HC). I urge all to look past the hot air and hype frenzy that are going on, because in the end, the HC platforms have to be aligned and congruent to the organization’s data architecture and business plans.

The announcement of Gartner’s latest Magic Quadrant on Integrated Systems (read hyper convergence) has put Nutanix as the leader of the pack as of August 2015. Clearly, many of us get caught up because it is the “greatest feeling in the world”. However, this faux feeling is not reality because there are many factors that made the pack leaders in the Magic Quadrant (MQ).

Gartner MQ Integrated Systems Aug 2015

First of all, the MQ is about market perception. There is no doubt that the pack leaders in the Leaders Quadrant have earned their right to be there. Each company’s revenue, market share, gross margin, company’s profitability have helped put each as leaders in the pack. However, it is also measured by branding, marketing, market perception and acceptance and other intangible factors.

Secondly, VMware EVO: Rail has split the market when EMC has 3 HC solutions in VCE, ScaleIO and EVO: Rail. Cisco wanted to do their own HC piece in Whiptail (between the 2014 MQ and 2015 MQ reports), and closed down Whiptail when their new CEO came on board. NetApp chose EVO: Rail and also has the ever popular FlexPod. That is why you see that in this latest MQ report, NetApp and Cisco are interpreted independently whereas in last year’s report, it was Cisco/NetApp. Market forces changed, and perception changed.  Continue reading →

Washing too much software defined

There’s been practically a firestorm when EMC announced ViPR, its own version of “software-defined storage” at EMC World last week. Whether you want to call it Virtualization Platform Re-defined or Re-imagined, competitors such as NetApp, HDS, Nexenta have taken pot-shots at EMC, and touting their own version of software-defined storage.

In the release announcement, EMC claimed the following (a cut-&-paste from the announcement):

  • The EMC ViPR Software-Defined Storage Platform uniquely provides the ability to both manage storage infrastructure (Control Plane) and the data residing within that infrastructure (Data Plane).
  • The EMC ViPR Controller leverages existing storage infrastructures for traditional workloads, but provisions new ViPR Object Data Services (with access via Amazon S3 or HDFS APIs) for next-generation workloads. ViPR Object Data Services integrate with OpenStack via Swift and can be run against enterprise or commodity storage.
  • EMC ViPR integrates tightly with VMware’s Software Defined Data Center through industry standard APIs and interoperates with Microsoft and OpenStack.

The separation of the Control Plane and the Data Plane of the ViPR allows the abstraction of 2 main layers.

Layer 1 is the abstraction of the underlying storage hardware infrastructure. Although I don’t have the full details (EMC guys please enlighten me, please!), I believe storage administrator no longer need to carve out LUNs from RAID groups or Storage Pools, striped and sliced them and further provision them into meta file systems before they are exported or shared through NAS protocols. I am , of course, quoting the underlying provisioning architecture of Celerra, which can be quite complex. Anyone who has done manual provisioning with Celerra Manager should know what I mean.

Here’s the provisioning architecture of Celerra:

The big boys better be flash friendly

An interesting article came up in the news this week. The article, from the ever popular The Register, mentioned 3 up and rising storage stars, Nimble Storage, Tintri and Tegile, and their assault on a flash strategy “blind spot” of the big boys, notably EMC and NetApp.

I have known about Nimble Storage and Tintri for a couple of years now, and I did take some time to read up on their storage technology offering. Tegile is new to me when it appeared on my radar after SearchStorage.com announced as the Gold Winner of the enterprise storage category for 2012.

The Register article intriqued me because it implied that these traditional storage vendors such as EMC and NetApp are probably doing a “band-aid” when putting together their flash storage strategy. And typically, I see these strategic concepts introduced by these 2 vendors:

  1. Have a server-side cache strategy by putting a PCIe card on the hosting server
  2. Have a network-based all-flash caching area
  3. Have a PCIe-based flash card on the storage system
  4. Have solid state drives (SSDs) in its disk shelves enclosures

In (1), EMC has VFCache (the server side caching software has been renamed to XtremSW Cache and under repackaging with the Xtrem brand name) and NetApp has it FlashAccel solution. Previously, as I was informed, FlashAccel was using the FusionIO ioTurbine solution but just days ago, NetApp expanded the LSI Nytro WarpDrive into its FlashAccel solution as well. The main objective of a server-side caching strategy using flash is to accelerate mostly read-based I/O operations for specific application workloads at the server side.

Is there no one to challenge EMC?

It’s been a busy, busy month for me.

And when the IDC Worldwide Quarterly Disk Storage Systems Tracker for 3Q12 came out last week, I was reading in awe how impressive EMC was at the figures that came out. But most impressive of all is how the storage market continue to grow despite very challenging and uncertain business conditions. With the Eurozone crisis, China experiencing lower economic growth numbers and the uncertainty in the US economic sectors, it is unbelievable that the storage market grew 24.4% y-o-y. And for the first time, 7,104PB was shipped! Yes folks, more than 7 exabytes was shipped during that period!

In the Top 5 external disk storage market based on revenue, only EMC and HDS recorded respectable growth, recording 8.7% and 13.8% respectively. NetApp, my “little engine that could” seems to be running out of steam, earning only 0.9% growth. The rest of the field, IBM and HP, recorded negative growth. Here’s a look at the Top 5 and the rest of the pack:

HP -11% decline is shocking to me, and given the woes after woes that HP has been experiencing, HP has not seen the bottom yet. Let’s hope that the new slew of HP storage products and technologies announced at HP Discover 2012 will lift them up. It also looked like a total rebranding of the HP storage products as well, with a big play on the word “Store”. They have names like StoreOnce, StoreServ, StoreAll, StoreVirtual, StoreEasy and perhaps more coming.

The Open SAN market, which includes iSCSI has EMC again at Number 1, with 29.8%, followed by IBM (14%), HDS (12.2%) and HP (11.8%). When combined with NAS numbers, the NAS + Open SAN market, EMC has 33.5% while NetApp is 13.7%.

Of course, it is just not about external storage because the direct-attached storage numbers count too. With that, the server vendors of IBM, HP and Dell are still placed behind EMC. Here’s a look at that table from IDC:

There’s a highlight of Dell in the table above. Dell actually grew by 4.0% compared to decline in HP and IBM, gaining 0.1%. However, their numbers seem too tepid and led to the exit of Darren Thomas, Dell’s storage group head honco. News of Darren’s exit was on TheRegister.

I also want to note that NAS growth numbers actually outpaced Open SAN numbers including iSCSI.

This leads me to say that there is a dire need for NAS technical and technology expertise in the local storage market. As the adoption of NFSv4 under way and SMB 2.0 and 3.0 coming into the picture, I urge all storage networking professionals who are more pro-SAN to step out of their comfort zone and look into NAS as well. The world is changing and it is no longer SAN vs NAS anymore. And NFSv4.1 is blurring the lines even more with the concepts of layout.

But back to the subject to storage market, is there no one out there challenging EMC in a big way? NetApp was, some years ago, recorded double digit growth and challenging EMC neck-and-neck, but that mantle seems to be taken over by HDS. But both are long way to go to get close to EMC.

Kudos to the EMC team for damn good execution!

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 →

Xtreme future?

By | | , , , , ,

EMC acquisition of XtremIO sent shockwaves across the industry. The news of the acquisition, reported costing EMC USD$430 million can be found here, here and here.

The news of EMC’s would be acquisition a few weeks ago was an open secret and rumour has it that NetApp was eyeing XtremIO as well. Looks like EMC has beaten NetApp to it yet again.

The interesting part was of course, the price. USD$430 million is a very high price to pay for a stealthy, 2-year old company which has 2 rounds of funding totaling USD$25 million. Why such a large amount?

XtremIO has a talented team of engineers; the notable ones being Yaron Segev and Shahar Frank. They have their background in InfiniBand, and Shahar Frank was the chief architect of Exanet scale-out NAS (which was acquired by Dell). However, as quoted by 451Group, XtremeIO is building an all-flash SAN array that “provides consistently high performance, high levels of flash endurance, and advanced functionality around thin provisioning, de-dupe and space-efficient snapshots“.

Furthermore, XtremeIO has developed a real-time inline deduplication engine that does not degrade performance. It does this by spreading the write I/Os over the entire array. There is little information about this deduplication engine, but I bet XtremIO has developed a real-time, inherent deduplication file system that spreads all the I/Os to balance the wear-leveling as well as having scaling performance. I bet XtremIO will dedupe everything that it stores, has a B+ tree, copy-on-write file system with a super-duper efficient hashing algorithm for address mapping (pointers) with this deduplication file system. Ok, ok, I am getting carried away here, because it is likely that I will be wrong, but I can imagine, can’t I?

Server way of locked-in storage

By | | , , , , , , , , , , ,

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.

Similarly, Dell announced their ExpressFlash solution that ties up its 12th generation PowerEdge servers with their flagship (what else), Dell Compellent storage.

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.

 

Gartner WW ECB 4Q11

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?

IDC 4Q11 Tracker numbers are in

It was a challenging 2011 but the tremendous growth of data continues to spur the growth of storage. According to IDC in its latest Worldwide Quarterly Disk Storage Systems Tracker, the storage market grew a healthy 7.7% in factory revenues, and the total disk storage capacity shipped was 6,279 petabytes, up 22.4% year-on-year! What Greg Schulz once said was absolutely true. “There is no recession in storage” 

Let’s look at the numbers. Overall, the positions of the storage vendors did not change much, but to me, the more exciting part is the growth quarter over quarter.

EMC and NetApp continue to post double digit growth perennially, with 25.9% and 16.6% respectively. Once again, taking market share from HP and others. HP, with the upheaval that is going on right now throughout the organization, got hit badly with a decline of 3.8%, while IBM held ground of 0.0%. And a data growth of 0.0% when the data growth is at more than 20% is not good, not good at all.

HDS, continuing its momentum with a good story, took a decent 11.6% and a fantastic number from HDS’s perspective. I have been out with my HDS buddies and I can feel their excitement and energy that I have never seen before. And that is a good indicator of the innovation and new technology that is coming out from HDS. They just need to work on their marketing and tell the industry more about what they are doing. Japanese can be so modest.

From the report, 2 things peeved me.

  • IDC reports that NetApp and HP are *tied* at 3rd. This does not make any sense at all! How can they be tied when NetApp has double digit growth, 11.2% market share and a revenue of USD$734 million while HP has negative growth, 10.3% market share and USD$677 million revenue? The logic boggles my mind!
  • They lumped Dell and Oracle into others! And others had a -1.4% growth. I am eager to find out how these 2 companies are doing, especially Dell who has been touting superb growth with their storage story.

Meanwhile, in TOTAL, here’s the table for the Total Worldwide Disk Storage Market share for 4Q11.

Numbers don’t lie. HP and IBM, in both 2nd and 3rd place respectively, are not in good shape. Negative growth in an upward trending market spells more trouble in the long run, and they had better buck up.

In this table, Dell gained and went up to #4 ahead of NetApp and from the look of things, Dell is doing all the right things to make sure that their storage market story is gelling together. Kudos! In fact, NetApp’s position and perception in the last 2-3 quarters have been shaky with Dell and HDS breathing down its neck. There isn’t likely to be significant dent to NetApp by HDS or Dell at this point in time, but having been the “the little engine that could” (that’s what I used to call NetApp) for the last few years, NetApp seems to be losing a bit of the extra “ooomph” that has excited the market in the past.

Lastly, I just want to say that my comments are based on the facts and figures in the tables published by IDC. I remember the last time I commented with the same approach, buddies of mine in the industry disagreed with me, saying that each of them are doing great in the Malaysian or South East Asian market.

Sorry guys, I blog I was see and I welcome you to take me to your sessions to let me know how well you are doing here. I would be glad to write more about it. (Hint, hint).

 

Battle of flash racks coming soon

By | |
1 Comment

The battle is probably already here. It has just begun for rack mounted flash-based or DRAM-based (or both) storage systems.

We have read in the news about the launch of EMC’s Project Lightning, and I wrote about it. EMC is already stirring up the competition, aiming its guns at FusionIO. Here’s a slide from EMC comparing their VFCache with FusionIO.

Not to be outdone, NetApp set its motion to douse the razzmatazz of EMC’s Lightning, announcing the future availability of their server-side flash software (no PCIe card) but it will work with major host-based/server-side PCIe Flash cards. (FusionIO, heads up). Ah, in Sun Tsu Art of War, this is called helping your buddy fight the bigger enemy.

NetApp threw some FUDs into the battle zone, claiming that EMC VFCache only supports 300GB while the NetApp flash software will support 2TB, NetApp multiprotocol, and VMware’s VMotion, DRS and HA. (something that VFCache does not support now).

The battle of PCIe has begun.

The next battle will be for the rackmounted flash storage systems or appliance. EMC is following it up with Project Thunder (because thunder comes after lightning), which is a flash-based storage system or appliance. Here’s a look at EMC’s preliminary information on Project Thunder.

And here’s how EMC is positioning different storage tiers in the following diagram below (courtesy of VirtualGeek), being glued together by EMC FAST (Fully Automated Storage Tiering) technology.

But EMC is not alone, as there are already several prominent start-ups out there, already offering flash-based, rackmount storage systems.

In the battle ring, there is Kaminario K2 with the SPEAR (Scale-out Performance Storage Architecture), Violin Memory with Violin Switched Memory (VXM) architecture, Purestorage Purity Operating Environment and SolidFire’s Element OS, just to name a few. Of course, we should never discount the grand daddy of all flash-based storage – Texas Memory Systems RamSAN.

The whole motion of competition in this new arena is starting all over again and it’s exciting for me. There is so much to learn about newer, more innovative architecture and I intend to share more of these players in the coming blog entries. It is time to take notice because the SSDs are dropping in price, FAST! And in 2012, I strongly believe that this is the next battle of the storage players, both established and start-ups.

Let the battle begin!
