Houston, we have an OpenStack problem

I have always wanted to look deeper into OpenStack, but I never got around to it. However, last week, something about NASA and OpenStack caught my attention … something about NASA pulling out of OpenStack development.

The spin was that “OpenStack has come on its own” is true, because OpenStack today has 180 (at last count on June 20th 2012) companies participating and contributing to the development, deployment and marketing of the highly popular Infrastructure-as-a-Service cloud computing project. So, the NASA withdrawal was not as badly felt as to what NASA had said next.

When NASA CIO Linda Cureton announced that NASA has shifted to Amazon Web Services (AWS) for their enterprise cloud-based infrastructure and they have saved almost a million dollars in costs, that was a clear and blatant impalement to the very heart and soul of OpenStack. NASA, one of the 2 founders of OpenStack in 2009, has switched sides to announce their preference to OpenStack’s rival, AWS. It pains me to just listen to the such a defection. Continue reading

Swiss army of data management

Back in 2000, before I joined NetApp, I bought one of my first storage technology books. It was “The Holy Grail of Data Storage Management” by Jon William Toigo. The book served me very well, because it opened up my eyes about the storage networking and data management world.

I mean, I have been doing storage for 7 years before the year 2000, but I was an implementation and support engineer. I installed my first storage arrays in 1993, the trusty but sometimes odd, SPARCstorage Array 1000. These “antiques” were running 0.25Gbps Fibre Channel, and that nationwide bank project gave me my first taste and insights of SAN. Point-to-point, but nonetheless SAN.

Then at Sun from 1997-2000, I was implementing the old Storage Disk Packs with FastWide SCSI, moving on to the A5000 Photons (remember these guys?) and was trained on the A7000, Sun’s acquisition of Encore way back in the late nineties. Then there was “Purple”, the T300s which I believe came from the acquisition of MaxStrat.

The implementation and support experience was good but my world opened up when I joined NetApp in mid-2000. And from the Jon Toigo’s book, I learned one of the most important lessons that I have carried with me till this day – “Data Storage Management is 3x more expensive that the data storage equipment itself“. Given the complexity of the data today compared to the early 2000s, I would say that it is likely to be 4-5x more expensive.

And yet, I am still perplexed that many customers and prospects still cannot see the importance and the gravity of data storage management, and more precisely, data management itself.

A couple of months ago, I had to opportunity to work on an RFP for project in Singapore. The customer had thousands of tapes storing digital media files in addition to tens of TBs running on IBM N-series storage (translated to a NetApp FAS3xxx). They wanted to revamp their architecture, and invited several vendors in Singapore to propose. I was working for a friend, who is an EMC reseller. But when I saw that tapes figured heavily in their environment, and the other resellers were proposing EMC Isilon and NetApp C-Mode, I thought that these resellers were just trying to stuff a square peg into a round hole. They had not addressed the customer’s issues and problems at all, and was just merely proposing storage for the sake of storage capacity. Sure, EMC Isilon is great for the media and entertainment business, but EMC Isilon is not the data management solution for this customer’s situation. Neither was NetApp with the C-Mode solution.

What the customer needed to solve was a data management solution, one that involved

  • Single namespace for video editors and programmers, regardless of online disk storage or archived tape storage
  • Transparent and automated storage tiering and addressing the value of the data to the storage media
  • A backup tier which kept a minimum 2 recent copies for file restoration in case of disasters
  • An archived tier which they could share with their counterparts in other regions
  • A transparent replication tier which would allow them to implement a simplified disaster recovery mechanism with their counterparts in Japan and China

And these were the key issues that needed to be addressed, not the scale-out, usual snapshot mechanism. These features are good for a primary, production storage infrastructure, but this customer’s business operations had about 70-80% data and files which were offline in tapes. I took the liberty to advise my friend to look into Quantum StorNext, because the solution could solve the business problem NOT solving it from an IT point of view. Continue reading

Expensive hard disk is good

No, I don’t mean to be bad, but the spinning HDDs’ prices will remain high even if the post-Thailand flood production has resumed to normalcy.

According to IHS iSuppli, a market research intelligence firm, the prices will continue to hold steady and will not fall to pre-flood level until 2014. The reason is simple. The prices of the hard disk drives are pretty much dictated by the only 2 real remaining hard disk companies in the world – Seagate and Western Digital. These guys controls more than 85% of the hard disk market and as demand of HDDs outstrips supply, the current hard disk prices are hitting the bottom line hard for just about everyone.

But the bad news is turning into good news for solid state storage devices. NAND-Flash based devices are driving a new clan of storage start-ups in the likes of Violin Memory, Kaminario, Pure Storage and Virident. The EMC acquisition of XtremIO was a strong endorsement that cements the cornerstone of all enterprise storage arrays to come. Even the Register predicted that the EMC VMAX will be the last primary storage array before the flash tsunami.

The NAND-Flash solid state of multi-level cells (MLCs) and single level cells (SLCs) and even triple level cells (TLCs) are going through birth, puberty, adolescent extremely fast because the demand for faster and faster IOPS, throughput and lower latency is hitting at full speed. And it is likely that all the xLCs (SLCs, MLCs and TLCs) could go through cycle in an extremely short lifespan, because there is a new class of solid state that is pushing the performance-price envelope closer and closer to speed of DRAM but with the price of Flash. This new type of solid state is Storage Class Memory (SCM). Continue reading

The reports are out!

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
