Of Object Storage, Filesystems and Multi-Cloud

Data storage silos everywhere. The early clarion call was to eliminate IT data storage silos by moving to the cloud. Fast forward to the present. Data storage silos are still everywhere, but this time, they are in the clouds. I blogged about this.

Object Storage was all the rage when it first started. AWS, with its S3 (Simple Storage Service) offering, started the cloud storage frenzy. Highly available, globally distributed, simple to access, and fitted superbly into the entire AWS ecosystem. Quickly, a smorgasbord of S3-compatible, S3-like object-based storage emerged. OpenStack Swift, HDS HCP, EMC Atmos, Cleversafe (which became IBM SpectrumScale), Inktank Ceph (which became RedHat Ceph), Bycast (acquired by NetApp to be StorageGrid), Quantum Lattus, Amplidata, and many more. For a period of a few years prior, it looked to me that the popularity of object storage with an S3 compatible front has overtaken distributed file systems.

What’s not to like? Object storage are distributed, they are metadata rich (at a certain structural level), they are immutable (hence secure from a certain point of view), and some even claim self-healing (depending on data protection policies). But one thing that object storage rarely touted dominance was high performance I/O. There were some cases, but they were either fronted by a file system (eg. NFSv4.1 with pNFS extensions), or using some host-based, SAN-client agent (eg. StorNext or Intel Lustre). Object-based storage, in its native form, has not been positioned as high performance I/O storage.

A few weeks ago, I read an article from Storage Soup, Dave Raffo. When I read it, it felt oxymoronic. SwiftStack was just nominated as a visionary in the Gartner Magic Quadrant for Distributed File Systems and Object Storage. But according to Dave’s article, Swiftstack did not want to be “associated” with object storage that much, even though Swiftstack’s technology underpinning was all object storage. Strange.

[Preamble: I am a delegate of Storage Field Day 14. My expenses, travel and accommodation are paid for by GestaltIT, the organizer and I am not obligated to blog or promote the technologies presented at this event. The content of this blog is of my own opinions and views]

I am here at the Commvault GO 2017. Bob Hammer, Commvault’s CEO is on stage right now. He shares his wisdom and the message is clear. IT to DT. IT to DT? Yes, Information Technology to Data Technology. It is all about the DATA.

The data landscape has changed. The cloud has changed everything. And data is everywhere. This omnipresence of data presents new complexity and new challenges. It is great to get Commvault acknowledging and accepting this change and the challenges that come along with it, and introducing their HyperScale technology and their secret sauce – Universal Dynamic Index.

The DellEMC Forum 2017 in Kuala Lumpur concluded yesterday. I was there to catch up with old friends, pick up gossips in the grapevine but most of all, to really see how the new DellEMC was doing.

From the news and sources for the past 1 year, everything looked fine and dandy. In fact, I was super impressed in the way the whole merger thing was going, because DellEMC was firing at all fronts.

And the DellEMC Forum started with some good energy. They brought out many of the storage, hyper-converged, software-defined solutions. On show, they had XtremIO, Scale IO, Isilon, and even a full hands-on lab booth at the corner end of the floor. DellEMC was also inclusive the SMB/SME segment, dedicating a separate pavilion for the SMB/SME solutions.

Solid in the Fire

December 22 2015: I kept this blog in draft for 6 months. Now I am releasing it as NetApp acquires Solidfire.

真金不怕紅爐火

The above is an old Chinese adage which means “True Gold fears no Fire“. That is how I would describe my revisited view and assessment of SolidFire, a high performance All-Flash array vendor which is starting to make its presence felt in South Asia.

I first blogged about SolidFire 3 years ago, and I have been following the company closely as more and more All-Flash array players entered the market over the 3 years. Many rode on the hype and momentum of flash storage, and as a result, muddied and convoluted the storage infrastructure market understanding. It seems to me spin marketing ruled the day and users could not make a difference between vendor A and vendor B, and C and D, and so on….

I have been often asked, which is the best All-Flash array today. I have always hesitated to say which is the best because there aren’t much to say, except for 2-3 well entrenched vendors. Pure Storage and EMC XtremIO come to mind but the one that had stayed under the enterprise storage radar was SolidFire, until now.

HDS HNAS kicks ass

I am dusting off the cobwebs of my blog. After almost 3 months of inactivity, (and trying to avoid the Social Guidelines Media of my present company), I have bolstered enough energy to start writing again. I am tired, and I am finishing off the previous engagements prior to joining HDS. But I am glad those are coming to an end, with the last job in Beijing next week.

So officially, I will be in HDS as of November 4, 2013 . And to get into my employer’s good books, I think I should start with something that HDS has proved many critics wrong. The notion that HDS is poor with NAS solutions has been dispelled with a recent benchmark report from SPECSfs, especially when it comes to NFS file performance. HDS has never been much of a big shouter about their HNAS, even back in the days of OEM with BlueArc. The gap period after the BlueArc acquisition was also, in my opinion, quiet unless it was the gestation period for this Kick-Ass announcement a couple of weeks ago. Here is one of the news circling in the web, from the ever trusty El-Reg.

HDS has never been big shouting like the guys, like EMC and NetApp, who have plenty of marketing dollars to spend. EMC Isilon and NetApp C-Mode have always touted their mighty SPECSfs numbers, usually with a high number of controllers or nodes behind the benchmarks. More often than not, many readers would probably focus more on the NFSops/sec figures rather than the number of heads required to generate the figures.

Unaware of this HDS announcement, I was already asking myself that question about NFSops/sec per SINGLE controller head. So, on September 26 2013, I did a table comparing some key participants of the SPECSfs2008_nfs.v3 and here is the table:

SPECSfs2008_nfs.v3-26-Sept-2013In the last columns of the 2 halves (which I have highlighted in Red), the NFSops/sec/single controller head numbers are shown. I hope that readers would view the performance numbers more objectively after reading this. Therefore, I let you make your own decisions but ultimately, they are what they are. One should not be over-mesmerized by the super million NFSops/sec until one looks under the hood. Secondly, one should also look at things more holistically such as $/NFSops/sec, $/ORT (overall response time), and $/GB/NFSops/managed and other relevant indicators of the systems sold.

But I do not want to take the thunder away from HDS’ HNAS platforms in this recent benchmark. In summary,

HDS SPECbench summaryTo reach a respectable number of 607,647 NFSops/sec with a sub-second response time is quite incredible. The ORT of 0.59 msecs should not be taken lightly because to eke just about a 0.1 msec is not easy. Therefore, reaching 0.5 millisecond is pretty awesome.

This is my first blog after 3 months. I am glad to be back and hopefully with the monkey off my back (I am referring to my outstanding engagements), I can concentrating on writing good stuff again. I know, I know … I still owe some people some entries. It’s great to be back 🙂

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.

The marriage in the cloud

Admit it! You are a terabyte junkie! I am sure many of us have one terabyte or more of your personal “stuff” at home. Heck, I even heard from a friend that he has almost 20TB of high definition movies (thank you Torrent!) at home! That’s crazy!

And what the typical Malaysian consumer would do after he or she runs out of hard disk space? In KL (our beloved capital city, Kuala Lumpur), they would throng the Low Yat IT mall or extensions of it, like Digital Mall in PJ Section 14. In other towns and cities in Malaysia, PC fairs are popular, as consumers try to get the best price possible (We Malaysian are good at squeezing the max of a deal)

It is difficult for the not-so-IT-literate consumer to differentiate which brand is the best. Buffalo, Iomega, DLink, Western Digital, etc, etc. But the tides are changing, because these vendors want to tie you down for the rest of your digital life. You see, buying a small NAS for the home now comes with a big carrot, an incentive to keep you wanting for more, and yet you can’t unbind yourself from the tether once you are hooked.

Cloud storage hasn’t taken off in a big way last year. But many cloud storage vendors know there are plenty of opportunities out there but how do they get the consumers to upload their files, photos and whatever stuff they might have, to cloud storage? Ingeniously, they work together with other smaller NAS storage players and use these vendor’s product offerings as baits. They bundle a significantly large FREE capacity or data protection offering in the Cloud Storage as the carrot, and once the consumer decides to put their files in the cloud storage, boom, they are ensnared to become a long term ATM machine to the Cloud Storage Provider.

Sneaky? No? I call this good, smart marketing. You have a market of opportunities out there, but cloud storage isn’t catching on. You have small NAS vendors that is reaching out to the market of consumer, but it’s a brutal, competitive arena and margins are razor thin. It’s a win-win situation for both sides.

And this trend is catching on. When I first read about Drobo (a high-end consumer NAS storage) partnering Carbonite (a remote backup vendor now repackaged as a Cloud storage backup provider), I thought it was a pretty darn good idea. It was a marriage that happened in the cloud. Late last year, another consumer NAS company, QNAP paired up with Symform, a cloud storage and backup vendor.

This was moving towards a market that scratches the itch. The consumers wanted reliable backup too, but consumer-grade disk drives fail ever so often. Laptops get stolen, and files could be infected by viruses. The list goes on, but the point is that the Cloud Storage Providers may have found a silver lining in getting the consumers to leap into the cloud. And the whole idea of small NAS vendor-big Cloud Backup dynamic duo, just got a big endorsement last night. Guess who has decided to dip its grubby hands into the pie?

EMC, the 800-pound gorilla of the information and storage world, through its Iomega subsidiary, wants your money! They had just married Iomega with EMC Atmos. It was quoted:

“EMC subsidiary and data protection specialist Iomega announced the integration between Iomega network storage solutions and EMC Atmos, extending Atmos cloud-based data protection and sharing to Iomega’s network storage product offerings. The new integration gives small and midsize businesses (SMBs), remote offices and distributed enterprises access to any Atmos powered cloud around the world.”

Surprised? Not really, but I guess EMC needs to breath new life into Atmos and this marriage just extended Atmos’ life support system.

Unofficial SNIA Malaysia Facebook group – You are invited!

Some of you might know that I am the incumbent SNIA Malaysia Chairman. But after doing my part for SNIA for the past 2 years, I wanted to step down in January 2012 and let some fresh new blood take over.

Unfortunately there were no takers for the position and both myself and my Vice-Chairman had decided to continue to run it for another year. It has not been easy because we volunteer for those positions. And I thank the good support from the SNIA folks in South Asia as well as the regulars who attend our meeting.

I can’t say that we are entirely successful in achieving good awareness about SNIA in Malaysia, and there is still a lot to do. But one thing I have always been very proud of was to start the *unofficial* SNIA Malaysia Facebook group. In the past 1 1/2 years, I have used it as a platform to share interesting things in this group, good or bad.

I felt that it is time I opened it up to a larger audience as the traffic on my blog has increased 2x in less than 6 months of its inception. It’s time to push the envelope and our limits in our generosity in sharing; testing our understanding in the areas of storage networking and data management; and notching it up a level to include international assessment.

I feel that this is the best way for us to improve ourselves, and participate globally with the best who are out there. I don’t claim to be an expert of things, and I am humbled by the many who supported me, us as SNIA Malaysia and my blog.

Since I am the admin of the FB group, you are welcomed to join us at http://www.facebook.com/groups/sniamalaysia/.

Please no spam. We are professionals who make mistakes and we want to help to spread the message that storage and data is very important.

So, join us by sending us a request, and please, please, give us your details and your background before we let you in. We want the Facebook group to be clean and professional.

Thank you
