EMC VFCache (aka “Project Lightning”) Is One Small Step, But an Important One

VFCache is a filter driver that caches writes

EMC VFCache (née Project Lightning) is a fairly simple offering: A server-based PCIe flash card that acts as a read cache with no integration with storage arrays or hypervisors. But EMC’s entrance into the host-based flash storage market is a powerful demonstration of the wave of disruption caused by flash-based storage and high-performance computing.

Nimbus E-Class: The First Big, Redundant, All-Flash Enterprise Array

The new Nimbus Data E-Class comes just at the right moment, with 500 TB of capacity, a fully redundant “dual active” controller architecture, massive performance (even InfiniBand), and complete feature set (once VAAI is released).

My Incomplete, Subjective List of Enterprise SSD Companies

Jean-Jacques Maleval posted a “complete list of 85 SSD manufacturers in the world” over at StorageNewsletter, and I was surprised to see so many unfamiliar names in the list. So here’s my own rundown of the enterprise SSD makers to keep an eye on in the coming year!

Micron Bursts Into the PCIe SSD Market

The Micron RealSSD P320h is more than a new form-factor for the company; it also introduces their RAIN technology

PCIe SSDs like Micron’s new P320h offer mindbending performance and enterprise class reliability. Although expensive, these devices are in an entirely different league from any other storage option. Micron promises to bring the PCIe P320h to market at nearly $15 per gigabyte, a substantial discount over other PCIe SSD competitors.

Commodity Hardware Always Wins

Get used to it: Commodity hardware like this Super Micro SBB server will dominate enterprise storage

The history of technology moves in fits and starts, but one trend trumps all else: An inevitable shift from fine-tuned specialized gear to general-purpose commodity building blocks. We see it in both hardware and software, and at all levels of the industry, from chips and wafers to operating systems and networking devices. Take a step back and you’ll certainly agree: Commodity hardware always wins (eventually).

Unconventional SSDs: PCI Express Mini Card (Mini PCI-E)

mSATA SSDs like this Toshiba model reuse reserved Mini-PCIe pins for SATA connections

With Apple almost certain to introduce a new MacBook Air, questions have turned to the specifics of the hardware to be used. A leaked pre-production photo features an odd memory configuration (not to mention four batteries), a device I immediately recognized as an SSD-on-a-stick. With this high-profile introduction of a new SSD stick form, I thought it was time to cover these unconventional new storage formats.

Hybrid SSD/Hard Disk Drives: This Time For Sure!

Hybrid can

Hard disk drive makers are adding flash storage to their conventional spinning-platter drives to improve performance and are targeting the performance PC market. Wait a second, haven’t we seen this before? As Rocky eventually said to Bullwinkle, “but that trick never works!”

Is Flash A Disk Or A Cache?

Flash, Cash, Disk

There is a battle shaping up in the enterprise storage industry. On one side are those who see flash storage as an upgrade for the disk drive, and on the other are those who see it as a cache between the CPU and the drive. It’s a fundamental difference of opinion – flash chips can [...]

SSD: So Close and Yet So Far

Solid state (NAND flash) storage is all the rage right now, but there are many lingering questions regarding its true performance, reliability, and cost. But no question is more important in determining its ultimate usefulness than that of location: Where should flash storage be placed to maximize return on investment? Storage companies have argued that [...]
