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

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

Oops, excuse me but your silo is showing

It is the morning that the SNIA Global Steering Committee reporting session is starting soon. I am in the office extremely early waiting for my turn to share the happenings in SNIA Malaysia.

And of late, I have been getting a lot of calls to catch up on hot technologies, notably All Flash Storage arrays and hyper-converged infrastructure. Even though I am now working for Interica, a company that focuses on Oil & Gas exploration and production software, my free coffee sessions with folks from the IT side have not diminished. And I recalled a week back in mid-March where I had coffee overdose!

Flash storage and hyperconvergence are HOT! Despite the hypes and frenzies of both flash storage and hyperconvergence, I still believe that integrating either or, or both, still have an effect that many IT managers overlook. The effect is a data silo.

The rise of the specialized appliance

Compute and storage are 2 components within the IT infrastructure which are surely converging. SAN and NAS are facing their greatest adversary yet, and could be made insignificant if the cloud and virtualization game had their way. This is giving rise to the a new breed of solution, a specialized appliance where both compute and storage are ONE. Rising from the ashes of shared storage (SAN and NAS, take note), we are beginning to see things going back to way of direct, internal storage.

There were some scuffles in the bushes about 5 years, where Sun (now Oracle) was ahead of its game. The Sun Fire X4500 (aka Thumper) was one of the strong candidates to challenge the SAN/NAS duopoly in this networked storage period. X4500 integrated both the server and the storage components together, using ZFS as a file system and volume manager to deliver a very high throughput on all the JBOD disks very efficiently. ZFS acted as the RAID, so there was no need to have specialized RAID hardware. This proved that a very high performance storage solution can be easily integrated using standard off-the-shelf infrastructure components and the x86 architecture. By combining both compute and storage together, there were hints that the industry was about to rise up to Direct-Attached Storage (DAS) again, despite its perceived weakness against SAN and NAS.

Unfortunately, the applications were not ready for DAS then. Besides ZFS, applications such as databases, emails and file servers were not ready to jump into the DAS bandwagon and watch them ride into the sunset. But the fairy tale seems to be retold again, and this time, the evidence that DAS could rise again is much stronger.

The catalyst to this disruptive force? Virtualization!

I mentioned that VMware is the silent storage killer a few blogs ago. Needless to say, that ruffled a few featheres among the readers. I have no doubt that virtualization is changing how we storage guys look at SAN and NAS. In a traditional setup, the SAN or NAS is setup to provision LUNs or mount points to the data storage for VMFS volumes in the VMware environment. It will then be the storage array to provide snapshots, replications, thin provisioning and so on.

Perhaps VMware is nit picking that managing storage arrays for VMFS volumes is difficult. From the VMware administrators view, they are right. They don’t want to know what’s going on below the VM-level. All they want is storage, any kind of storage and VMware will manage the volumes, snapshots, replication and thin  provisioning. Indeed they were already doing that since vStorage API was introduced. In the new release of VMware version 5.0, the ante has been upped even higher, making networked storage less and less significant.

If you want to know about vStorage API and stuff, below is a diagram of the integration of the various components at the VMware API level.


VMware can now use direct, internal storage look like shared storage. The Virtual Storage Appliance (VSA) does just that. VMware already has a thriving market from the community and hobbists for VMware Appliances.

The appliance market has now evolved into new infrastructure too. Using x86 architecture, off-the-shelf infrastructure components (sounds familiar?), companies such as Nutanix and Tintri are taking advantage of this booming trend to introduce specialized VMware appliances as shown in their advertisements on their respective web sites.

Here’s the Nutanix Ad:


Here’s the Tintri Ad:


Both Tintri and Nutanix are a new breed of appliances – specialized appliances for VMware.

At the same time, other applications are building these specialized appliances as well. I have mentioned Oracle Exadata many times in the past and Oracle Exadata is the perfect example an a fine-tuned, hardcore database engine to make the Oracle run at the best performance possible.

Likewise HP has announced their E5000 Messaging System for Microsoft Exchange. The E5000 is a specialized appliance optimized and well-tuned for the Microsoft Exchange Server 2010. From the words of HP,

“HP E5000 Messaging System is the industry’s first fully self-contained platform built for the next-generation of Microsoft Exchange to deliver enterprise-class messaging to businesses of all sizes. Built as a turnkey solution that can be up and running in a few hours vs. days, the HP E5000 Messaging System gives business users the experience they want most: large mailboxes, centralized archiving of mailboxes files and 24×7 access from any device. IT staffs benefit the solutions simplicity to setup, scale and manage and to meet new demands affordably. Ideal for multi-site enterprises as well as branch office and remote office environments, each HP Messaging System delivers greater simplicity and accelerates deployment with preconfigured solutions starting at 500 mailboxes up to 3000 mailboxes, while delivering large, 1 to 2.5GB mailbox sizes. Clients can grow by adding storage capacity or more appliances within the environment up from hundreds to thousands of mailboxes.”

What are the specs of this E5000 box, you say? Here you go:


And look at Row#2 in the table above … Direct, Internal Disks! Look at Row #4, Xeon CPUs! Both Compute and Storage in the same appliance!

While the HP E5000 announcement was recently, Hitachi Data Systems were already in the game early with their Unified Compute Platform and their Converged Platform for Microsoft Exchange with relatively the same idea – specialized appliances.

Perhaps the HDS solutions aren’t exactly direct, internal storage but the concept is still the same – specialized appliance. HDS Unified Compute Platform (UCP) has these components.


HDS Converged Platform for MS Exchange provides their specialized “appliance” with Reference Architectures that can support up to 68,000 Microsoft Exchange mailboxes. Here’s an architecture diagram of their “appliance”


There’s no denying that the networked storage landscape is changing. So are the computing platforms. We are already seeing the compute and storage components being integrated together, tighter than ever. The wave is rising for specialized appliances and it can only get more intense from now on.

No wonder HP’s Converged Infrastructure vision is betting on x86 architecture, simple storage platforms with SAS/SATA disks and Virtualization. Other vendors are doing the same as well – Cisco, NetApp and VMware with their FlexPod solution and EMC with their VBlocks of VMware, Cisco and EMC Storage.

Hail to the Rise of the Specialized Appliance!
