I am a big proponent of Go-to-Market (GTM) solutions. Technology does not stand alone. It must be in an ecosystem, and in each industry, in each segment of each respective industry, every ecosystem is unique. And when we amalgamate data, the storage infrastructure technologies and the data management into the ecosystem, we reap the benefits in that ecosystem.

Data moves in the ecosystem, from system to system, north to south, east to west and vice versa, random, sequential, ad-hoc. Data acquires different statuses, different roles, different relevances in its lifecycle through the ecosystem. From it, we derive the flow, a workflow of data creating a data pipeline. The Data Pipeline concept has been around since the inception of data.

To illustrate my point, I created one for the Oil & Gas – Exploration & Production (EP) upstream some years ago.

Cohesity SpanFS impressed me. Their filesystem was designed from ground up to meet the demands of the voluminous cloud-scale data, and yes, the sheer magnitude of data everywhere needs to be managed.

We all know that primary data is always the more important piece of data landscape but there is a growing need to address the secondary data segment as well.

Like a floating iceberg, the piece that is sticking out is the more important primary data but the larger piece beneath the surface of the water, which is the secondary data, is becoming more valuable. Applications such as file shares, archiving, backup, test and development, and analytics and insights are maturing as the foundational data management frameworks and fast becoming the bedrock of businesses.

The ability of businesses to bounce back after a disaster; the relentless testing of large data sets to develop new competitive advantage for businesses; the affirmations and the insights of analyzing data to reduce risks in decision making; all these are the powerful back engine applicability that thrust businesses forward. Even the ability to search for the right information in a sea of data for regulatory and compliance reasons is part of the organization’s data management application.

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.

The power of E8

[Preamble: I was a delegate of Storage Field Day 14 from Nov 8-10, 2017. My expenses, travel and accommodation were paid for by GestaltIT, the organizer and I was not obligated to blog or promote the technologies presented at this event. The content of this blog is of my own opinions and views]

E8 Storage technology update at Storage Field Day 14 was impressive. Out of the several next generation NVMe storage technologies I have explored so far, E8 came out as the most complete. It was no surprise that they won the “Best of Show” in the Flash Memory Summits for the “Most Innovative Flash Memory Technology” in 2016 and “Most Innovative Flash Memory Enterprise Business Application” for 2017.

Who is E8 Storage?

They came out of stealth in August 2016 and have been making waves with very impressive stats. When E8 was announced, their numbers were more than 10 million IOPS, with 100µsecs for reads and 40µsecs for writes. And in the SFD14 demo, they reached and past the 10 million IOPS numbers.

The design philosophy of E8 Storage is different than the traditional dual controller scale-up storage architecture design or the multi-node scale-out cluster design. In fact, from a 30,000 feet view, it is quite similar to a “SAN-client” design advocated by Lustre, leveraging a very high throughput, low latency network.

I haven’t had a preview of the Compellent technology for a long time. My buddies at Impact Business Solutions were the first to introduce the Compellent technology called Data Progression to the local Malaysian market and I was invited to a preview back then. Around the same time, I also recalled another rather similar preview invitation by PTC Singapore for the 3PAR technology called Adaptive Provisioning (it is called Adaptive Optimization now).

Storage tiering was on the rise in the 2009-2010 years. Both Compellent and 3PAR were neck and neck leading the conversation and mind share of storage tiering, and IBM easyTIER and EMC FAST (Fully Automated Storage Tiering) were nowhere to be seen or heard. Vividly, the Compellent Data Progression technology was much more elegant compared to the 3PAR technology. While both intelligent storage tiering technologies were equally good, I took that the 3PAR founders were ex-Sun Microsystems folks, and Unix folks sucked at UX. In this case, Compellent’s Data Progression was a definitely a leg up better than 3PAR.

History aside, this week I have the chance to get a new preview of the Compellent technology again. Compellent was now rebranded as the SC series and was positioned as the mid-range storage arrays of DellEMC. And together with the other Storage Field Day 14 delegates, I have the pleasure to experience the latest SC Data Progression technology update, as well their latest SC All-Flash.

In Data Progression, one interesting feature which caught my attention was the RAID Tiering. This was a dynamic auto expand and auto contract set of RAID tiers – RAID 10 and RAID 5/6 in the Fast Tier and RAID 5/6 in the Lower Tier. RAID 10, RAID 5 and RAID 6 on the same set of drives (including SSDs), and depending on the “hotness” of the data, the location of the data blocks switched between the several RAID tiers in the Fast Tier. Over a longer period, the data blocks would relocate transparently to the Capacity Tier from the Fast Tier.

The Data Progression technology is extremely efficient. The movement of the data between the RAID Tiers and between the Performance/Capacity Tiers are in pages instead of blocks, making the write penalty and bandwidth to a negligible minimum.

The Storage Field Day 14 delegates were also privileged to be the first to get into the deep dive of the new All-Flash SC, just days of the announcement of the All-Flash SC. The All Flash SC redefines and refines the Data Progression to the next level. Among the new optimization, NAND Flash in the SC (both SLCs and MLCs, read-intensive and write-intensive) set the Data Progression default page size from 2MB to 512KB. These smaller 512KB pages enabled reduced bandwidth for tiering between the write-intensive and the read-intensive tier.

I didn’t get the latest SC family photos yet, but I managed to grab a screenshot of the announcement from The Register of the new DellEMC SC Series.

I was very encouraged with the DellEMC Midrange Storage presentation. Besides giving us a fantastic deep dive about the DellEMC SC All-Flash Storage, I was also very impressed by the candid and straightforward attitude of the team, led by their VP of Product Management, Pierluca Chiodelli. An EMC veteran, he was taking up the hard questions onslaught by the SFD14 delegate like a pro. His team’s demeanour was critical in instilling confidence and trust in how the bloggers and the analysts viewed Dell EMC merger, and how the SC and the Unity series would pan out in the technology roadmap.

Unlike the fiasco I went through with the DellEMC Forum 2017 in Malaysia, where I was disturbed with 3 calls in 3 consecutive days by DellEMC Malaysia, I was left with a profound respect for this DellEMC Storage team. They strongly supported their position within the DellEMC storage universe, and imparted their confidence in their technology solution in the marketplace.

Without a doubt, in my point of view, this DellEMC Mid-Range Storage team was the best I have enjoyed in Storage Field Day 14. Thank you.

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.

[Preamble: I will be 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 in this event]

I am off to the US again next Monday. I am attending Storage Field Day 14 and it will be a 20+ hour long haul flight. But this SFD has a special twist, because I will be Washington DC first for Commvault GO 2017 conference. And I can’t wait.

My first encounter with Commvault goes way back in early 2001. I recalled they had their Galaxy version but in terms of market share, they were relatively small compared to Veritas and IBM at the time. I was with NetApp back then, and customers in Malaysia hardly heard of them, except for the people in Shell IT International (SITI). For those of us in the industry, we all knew that SITI worldwide had an exclusive Commvault fork just for them.

Cloud silos after eliminating silos

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

I love cloud computing. I love the economics and the agility of the cloud and how it changed IT forever. The cloud has solved some of the headaches of IT, notably the silos in operations, the silos in development and the silos in infrastructure.

The virtualization and abstraction of rigid infrastructures and on-premise operations have given birth to X-as-a-Service and Cloud Services. Along with this, comes cloud orchestration, cloud automation, policies, DevOps and plenty more. IT responds well to this and thus, public clouds services like Amazon Web Services, Microsoft Azure, and Google Cloud Platforms are dominating the landscape. Other cloud vendors like Rackspace, SoftLayer, Alibaba Cloud are following the leaders pack offering public, private, hybrid and specialized services as well.

In this pile, we can now see the certain “camps” emerging. Many love Azure Stack and many adore AWS Lambda. Google just had their summit here in Malaysia yesterday, appealing to a green field and looking for new adopters. What we are seeing is we have customers and end users adopting various public cloud services providers, their services, their ecosystem, their tools, their libraries and so on. We also know that many customers and end users having several applications on AWS, and some on Azure and perhaps looking for better deals with another cloud vendor. Multi-cloud is becoming flavour of the season, and that word keeps appearing in presentations and conversations.

Yes, multi-cloud is a good thing. Customers and end users would love it because they can get the most bang for their buck, if only … it wasn’t so complicated. There aren’t many “multi-cloud” platforms out there yet. Continue reading →

Pure Electric!

I didn’t get a chance to attend Pure Accelerate event last month. From the blogs and tweets of my friends, Pure Accelerate was an awesome event. When I got the email invitation for the localized Pure Live! event in Kuala Lumpur, I told myself that I have to attend the event.

The event was yesterday, and I was not disappointed. Coming off a strong fiscal Q1 2018, it has appeared that Pure Storage has gotten many things together, chugging full steam at all fronts.

When Pure Storage first come out, I was one of the early bloggers who took a fancy of them. My 2011 blog mentioned the storage luminaries in their team. Since then, they have come a long way. And it was apt that on the same morning yesterday, the latest Gartner Magic Quadrant for Solid State Arrays 2017 was released.

The changing face of storage

“No, we are not a storage company anymore. We are a data management company now.“

I was reading a Forbes article interviewing NetApp’s CIO, Bill Miller. It was titled:

NetApp’s CIO Helps Drive Company’s Shift From Data Storage To Data Management

I was fairly surprised about the time it took for that mindset shift messaging from storage to data management. I am sure that NetApp has been doing that for years internally.

To me, the writing has been in the wall for years. But weak perception of storage, at least in this part of Asia, still lingers as that clunky, behind the glassed walls and crufty closets, noisy box of full of hard disk drives lodged with snakes and snakes of orange, turquoise or white cables. 😉

The article may come as a revelation to some, but the world of storage has changed indefinitely. The blurring of the lines began when software defined storage, or even earlier in the form of storage virtualization, took form. I even came up with my definition a couple of years ago about the changing face of storage framework. Instead of calling it data management, I called the new storage framework,  the Data Services Platform.

So, this is my version of the storage technology platform of today. This is the Data Services Platform I have been touting to many for the last couple of years. It is not just storage technology anymore; it is much more than that.
