The Return of SAN and NAS with AWS?

AWS what?

Amazon Web Services announced Outposts at re:Invent last week. It was not much of a surprise for me because when AWS had their partnership with VMware in 2016, the undercurrents were there to have AWS services come right at the doorsteps of any datacenter. In my mind, AWS has built so far out in the cloud that eventually, the only way to grow is to come back to core of IT services – The Enterprise.

Their intentions were indeed stealthy, but I have been a believer of the IT pendulum. What has swung out to the left or right would eventually come back to the centre again. History has proven that, time and time again.

SAN and NAS coming back?

A friend of mine casually spoke about AWS Outposts announcements. Does that mean SAN and NAS are coming back? I couldn’t hide my excitement hearing the return but … be still, my beating heart!

I am a storage dinosaur now. My era started in the early 90s. SAN and NAS were a big part of my career, but cloud computing has changed and shaped the landscape of on-premises shared storage. SAN and NAS are probably closeted by the younger generation of storage engineers and storage architects, who are more adept to S3 APIs and Infrastructure-as-Code. The nuts and bolts of Fibre Channel, SMB (or CIFS if one still prefers it), and NFS are of lesser prominence, and concepts such as FLOGI, PLOGI, SMB mandatory locking, NFS advisory locking and even iSCSI IQN are probably alien to many of them.

What is Amazon Outposts?

In a nutshell, AWS will be selling servers and infrastructure gear. The AWS-branded hardware, starting from a single server to large racks, will be shipped to a customer’s datacenter or any hosting location, packaged with AWS popular computing and storage services, and optionally, with VMware technology for virtualized computing resources.

In a move ala-Azure Stack, Outposts completes the round trip of the IT Pendulum. It has swung to the left; it has swung to the right; it is now back at the centre. AWS is no longer public cloud computing company. They have just become a hybrid cloud computing company. Continue reading

Oracle Cloud Infrastructure to prove skeptics wrong

[Preamble: I have been invited by  GestaltIT as a delegate to their TechFieldDay from Oct 17-19, 2018 in the Silicon Valley USA. My expenses, travel and accommodation are covered by GestaltIT, the organizer and I was not obligated to blog or promote their technologies presented at this event. The content of this blog is of my own opinions and views]

The much maligned Oracle Cloud is getting a fresh reboot, starting with their Oracle Cloud Infrastructure (OCI), and significant enhancements and technology updates were announced at the Oracle Open World this week. I had the privilege to hear about Oracle Cloud’s new attack plan when they presented at Tech Field Day 17 last week.

Oracle Cloud has not have the best of days in recent months. Thomas Kurian’s resignation as their President of Product Development was highly publicized in a disagreement with CTO and founder, Larry Ellison over cloud software strategy. Then there was an on-going lawsuit about how Oracle was misrepresenting their cloud revenue growth, which puts Oracle in a bad light.

On the local front here in Malaysia, I have heard from the grapevine of the aggressive nature of Oracle personnel pushing partners and customers to adopt their cloud services using legal scare tactics on their database licensing. A buddy of mine, who was previously the cloud business development manager at CTC Global, also shared Oracle’s cloud shortcomings compared to Amazon Web Service and Microsoft Azure a year ago.

Oracle Cloud Infrastructure team aimed to turnover the bad perceptions, starting with the delegates of Tech Field Day 17, including yours truly.Their strategy was clear. Oracle Cloud Infrastructure runs the highest performance and the highest enterprise grade Infrastructure-as-a-Service (IaaS), bar none. Unlike the IBM Cloud, which in my opinion is a wishy-washy cloud service platform, Oracle Cloud’s ambition is solid.

They did a demo on JDEdwards EnterpriseOne application, and they continue to demonstrate their prowess running the highest performance computing experience ever, for all enterprise-grade workload. And that enterprise pedigree is clear.

Just this week, Amazon Prime Day had an outage. Amazon is in the process of weaning Oracle database from their entire ecosystem by 2020, and this outage clearly showed that the Oracle database and the enterprise applications would only run best on Oracle Cloud Infrastructure.

I have attended a bunch of Storage Field Days over the years but I have never attended a Tech Field Day. This coming week, I will be attending their 17th edition, TechFieldDay 17, but my first. I have always enjoyed Storage Field Days. Everytime I joined as a delegate, there were new things to discover but almost always, serendipity happened.

FlashForward to Beyond

The flash frenzy has reached its zenith in 2016. We now no longer are interested in listening to storage technology vendors touting the power of solid state storage (NAND Flash included) over spinning drives.

The capacity of 3D NAND Flash SSDs has reached a whopping 15.3TB (that is even bigger than the 12TB 7200RPM HDDs of today), and with deduplication and compression, the storage efficiency has reached a conservative 4:1 or 5:1. Effective capacity of most mid-end storage arrays can easily reach 1-2 Petabytes.

And flash and hybrid platforms have reached maturity in these few short years. So what is next?

The landscape has obviously changed. The performance landscape, the capacity landscape and all related to the storage data points have changed. And the speed of SSDs together with the up-and-coming NVMe and NVDIMM technology in new storage array controllers are also shifting the data bottlenecks to another part of the architecture. The development of I/O communications and interfaces has to change as well, to take advantage of the asynchronous I/Os in storage tiering and caching using NAND Flash.

With this mature and well understood landscape, it is time to take Flash to the next level. This next level comes in the form of an exciting end-user conference in Singapore on 25th April 2017. It is called FlashForward.

The 2016 FlashForward event in Europe has already garnered great support from the cream of the storage technologists around the world, and had fantastic feedbacks from the end-user attendees. That FlashForward event has also seen the birth of an international business and technology exchange in its inaugural introduction.  Yes, it is time to learn from the field experts, and it is time to build on the Flash Platform for new Data Services.

From the sponsorship package brochure I have received, it is definitely an event not to be missed.

The FlashForward Conference in Singapore is exquisitely procured by Evito Ltd, under the stewardship of Mr. Paul Talbut. Paul is a very seasoned veteran in the global circuit as an SNIA director of several initiatives. He has been immensely involved in the development of several SNIA chapters around the world, including South Asia, Malaysia, India, China, and even Brazil. He also leads by example with the SNIA Global Steering Committee (GSC); he is the SNIA Global Education Director and at one time, SNIA DPCO (Data Protection & Capacity Optimization) global proctor.

I have had the honour working with Paul for almost 8 years now, and I am sure he will lead the FlashForward Conference with valuable insights and experiences.

This is probably the greatest period for the industry and end users to get involved in the FlashForward Conference. For one, it is endorsed by SNIA, the vendor-neutral association which has been the growth beacon of the storage networking industry.

Secondly, it is the perfect opportunity for technology vendors to build their mindshare with end users and customers. And with the endorsement of the independent field experts and technology practitioners, end users would have a field day garnering approvals for their decisions, as well as learning the best practices to build upon the Flash technology they have implemented in their data center space.

The sponsorship packages are listed below, and I do encourage technology vendors, especially the All-Flash vendors to use the FlashForward conference as a platform to build their mindshare, and most of all, their branding. Continue reading

Praying to the hypervisor God

I was reading a great article by Frank Denneman about storage intelligence moving up the stack. It was pretty much in line with what I have been observing in the past 18 months or so, about the storage pendulum having swung back to DAS (direct attached storage). To be more precise, the DAS form factor I am referring to are physical server hardware that houses many disk drives.

Like it or not, the hypervisor has become the center of the universe in the IT space. VMware has become the indomitable force in the hypervisor technology, with Microsoft Hyper-V playing catch-up. The seismic shift of these 2 hypervisor technologies are leading storage vendors to place them on to the altar and revering them as deities. The others, with the likes of Xen and KVM, and to lesser extent Solaris Containers aren’t really worth mentioning.

This shift, as the pendulum swings from networked storage back to internal “direct-attached” storage are dictated by 4 main technology factors:

  • The x86 server architecture
  • Software-defined
  • Scale-out architecture
  • Flash-based storage technology

Anyone remember Thumper? Not the Disney character from the Bambi movie!

thumper-bambi-cartoon-character

When the SunFire X4500 (aka Thumper) was first released in (intermission: checking Wiki for the right year) in 2006, I felt that significant wound inflicted in the networked storage industry. Instead of the usual 4-8 hard disk drives in the all the industry servers at the time, the X4500 4U chassis housed 48 hard disk drives. The design and architecture were so astounding to me, I even went and bought a 1U SunFire X4150 for my personal server collection. Such was my adoration for Sun’s technology at the time.

Time for Fujitsu Malaysia to twist and shout and yet …

The worldwide storage market is going through unprecedented change as it is making baby steps out of one of the longest recessions in history. We are not exactly out of the woods yet, given the Eurozone crisis, slowing growth in China and the little sputters in the US economy.

Back in early 2012, Fujitsu has shown good signs of taking market share in the enterprise storage but what happened to that? In the last 2 quarters, the server boys in the likes of HP, IBM and Dell storage market share have either shrunk (in the case of HP and Dell) or tanked (as in IBM). I would have expected Fujitsu to continue its impressive run and continue to capture more of the enterprise market, and yet it didn’t. Why?

I was given an Eternus storage technology update by the Fujitsu Malaysia pre-sales team more than a year ago. It has made some significant gains in technology such as Advanced Copy, Remote Copy, Thin Provisioning, and Eco-Mode, but I was unimpressed. The technology features were more like a follower, since every other storage vendor in town already has those features.

It’s all about executing the story

I have been in hibernation mode, with a bit of “writer’s block”.

I woke up in Bangalore in India at 3am, not having adjusted myself to the local timezone. Plenty of things were on my mind but I can’t help thinking about what’s happening in the enterprise storage market after the Gartner Worldwide External Controller-Based report for 4Q12 came out  last night. Below is the consolidated table from Gartner:

Just a few weeks ago, it was IDC with its Worldwide Disk Storage Tracker and below is their table as well:

And Cloud Storage will make us even stranger

It was a dark and stormy night ….

I was in a car with my host in the stifling traffic jams on the streets of Jakarta. We had just finished dinner and his driver was taking me back to the hotel. It was about 9pm and we were making conversation trying to figure out how we can work together. My host, a wonderful Singaporean who has been residing in Jakarta for more than a decade and a half, owns a distributorship focusing mainly on IT security solutions. He had invited me over to Jakarta to give a talk on Cloud Storage at the Indonesia CIO Network event on January 9th 2013.

I was there to represent SNIA South Asia to give a talk about CDMI (Cloud Data Management Interface), and my host also took the opportunity to introduce Nutanix, a SAN-less 2-tier, high-performance, virtualized data center platform. (Note: That’s quite a mouthful, but gotta include all the buzz-words in there). It was my host’s first foray into storage networking solutions, away from his usual security solutions spread. As the conversation went on in the car, he said “You storage guys are so strange!“.

To many of the IT folks who have been involved in OS, applications, security, and networking, to say a few, storage is like a dark art, some mumbo jumbo, voodoo-like science known to a select few. That’s great, because this perception will keep us relevant, and still have the value and a job. To me, that just fine and dandy, and I like it that way. 🙂

In preparation to the event, I have to learn up SNIA CDMI. Cloud and Storage … Cloud and Storage … Cloud and Storage. Hmmm …. Continue reading

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!

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
