What is NVMe? And what does it mean for PCIe-SSD?

Good post by George Crump (thank you)

There are two constants in data center storage; the need for greater performance and the need for greater capacity. Flash based storage devices have become the go-to option to address the first challenge. But application owners and users quickly move from an initial euphoria with flash performance to demanding more. Since the flash NAND is essentially the constant in the equation, the surrounding infrastructure has to evolve to extract optimal performance from the technology. But achieving maximum performance often leads to proprietary architectures and designs. NVMe (Non Volatile Memory) is a new industry standard that enables data centers to realize full flash potential without compatibility headaches.

Hardware First – Designing All-Flash Arrays From a Hardware First Perspective

Good post by George Crump (thank you)

Data centers have to meet the increasing performance demands of scale out databases, big data analytics, and dense virtual environments. These data centers need to meet these demands without requiring more data center floor space or consuming more power. All-flash arrays seem to be the “default” answer to today’s storage performance problems. But all of these systems are not created equal. How the all-flash hardware and software are designed, and how these two components work together, will impact short-term results and long-term potential of the flash investment.

How often do you upgrade your storage array software?

Good post by Alex Galbraith (thank you)

Upgrades are scary!

Having managed and implemented upgrades on highly available systems such as the old Sun StorageTech line of rebranded HDS USP/VSP arrays back in the day, I can tell you that we did not take upgrades lightly!

Unless there was a very compelling reason for an upgrade, the line taken was always “if it ain’t broke, don’t fix it”, but then we were looking after storage in a massively high security environment where even minor changes were taken very seriously indeed.

How can SD cards be faster than SSDs?

Good post by Robin Harris (thank you)

SD cards – postage stamp sized flash cards in your camera – have no internal cache, little internal bandwidth, tiny CPUs, and slow I/O busses. But recent tests found that SD cards could be 200 times faster than an SSD. How???

Purely Observations on Dell / EMC Deal

Post by Scott Dietzen (thank you)

Big news out of Round Rock, Texas and Hopkinton, Massachusetts yesterday: Dell and EMC have signed a definitive agreement under which Dell, together with Michael Dell, MSD Partners and Silver Lake, will acquire EMC. We want to share our insights on this news, and explain what it means for the storage market.

Pure Storage both cooperates and competes with both companies. Many of our customers also run Dell servers and VMware software, but we of course compete with both EMC and Dell storage. Our thoughts:

Too much of a Good Thing? IBM Buys Cleversafe

Good post by George Crump (thank you)

The industry is mesmerized by all things flash and sometimes forgets that IT professionals have other challenges to face than just meeting the performance demands of the modern data center. One of those is dealing with unstructured data. Data centers are drowning in data and are looking for solutions that can cost-effectively and reliably, store all of it. Despite its slower than expected adoption rate, object storage remains an ideal way to store and retain all the data that organizations capture. To that end, IBM has purchased one of the top companies in the object storage market; Cleversafe.

DCIG 2015 AFA Buyer’s Guide is Fantastically Horrible

Good post by Brian Beeler (thank you)

Last week DCIG published their “2015-16 All-Flash Array Buyer’s Guide.” We’ve grown accustomed to ignoring most “Magic” and “Best Of” quadrants and awards respectively because almost every time they’re garbage. Analysts or media members anoint some vendor or technology best, shiniest, most rectangle or whatever else they can come up with to promote their own brand. What’s worse are the awards that are paid for, an even more disturbing part of enterprise IT sales and marketing.

What’s a PaaS?

Post from Ben Finkel and Garth Schulte (thank you)

With spending on Platform-as-a-Service expected to exceed $20 billion in this decade, Web developers need to get a firm understanding of the technology.

The recent explosion of public cloud services has made a dramatic impact across all fields in the IT industry. No one involved in this field can afford to ignore the trends and features that the cloud brings, all of which promise to continue to upend our industry for the foreseeable future.

Where VSAN doesn’t shine: Sources explain EMC’s ScaleIO purpose

Good post by Chris Mellor (thank you)

EMC introduced its scale-out ScaleIO Node virtual SAN a couple of weeks ago, with hybrid flash-disk and all-flash server chassises. It overlaps as a product with EMC-owned VMware’s VSAN, and therefore EMC’s EVO:RAIL implementation of that, and also competes with scale-out all-flash arrays.

Discussions with sources have clarified EMC’s thinking on the topic, and showed that the overlap is less than originally thought.

XPoint put under the analyst microscope

Good post by Chris Mellor (thank you) over at El Reg

80-page report gets under the skin of memristor-slaying 3D XPoint tech

Semiconductor market researcher Jim Handy of Objective Analysis has produced an 80-page report looking into what XPoint memory is, how it could be used and what its prospects are.

XPoint memory was unveiled by Micron and Intel in July to general amazement. The pair claimed it was 1,000 times faster than NAND, ten times denser and also less costly than DRAM, and would form a new memory hierarchy between DRAM and flash.
