Defining Software-Defined Storage – what benefits does it deliver?

Post by Eric Slack (thank you)

Software-Defined Storage (SDS) is one of the hottest topics in the IT industry and, as a technology, provides some significant advantages over traditional storage system designs. These advantages translate into substantial benefits that arguably have driven the interest in SDS products to begin with. But not all products labeled as “software-defined” come with all those benefits. For users it’s important to understand what they’re trying to get from SDS and which solutions can deliver it.

HP StoreVirtual VSA: An introduction

Good post by Calvin Zito (thank you)

I’ve been spending a lot of time on SpiceWorks for almost a year. And one of the topics that comes up repeatedly is explaining what a VSA is. If you’ve been reading ATSB for a while, you probably have a good idea what it is but from what I’ve seen on SpiceWorks, many of you don’t really know what it is.  So today’s post will serve as a bit of an introduction to StoreVirtual VSA and I’ll pull StoreOnce VSA into the discussion as well.

SSD Endurance. What does it mean to you?

Good post by Andrey Kudryavtsev (thank you)

I continuously think about the endurance aspect of our products, how SSD users understand it and use it for its positive benefits. Sadly, endurance is often underestimated and sometimes overestimated. I see customers buying High Endurance products for the benefit of protection, without understanding the real requirements of the application. Now that piece of night thoughts goes to my blog.

Netlist Readies PCIe Based High Performance NVRAM

Post by George Crump (thank you)

The ever-increasing density of virtual infrastructures, and the need to scale databases larger than ever, is creating an ongoing need for faster storage. And while flash has become the “go to” performance option, there are environments that still need more. Nonvolatile DRAM is the heir apparent, but it often requires customized motherboards to implement, for which widespread availability could be years away. Netlist, pioneer of NVRAM, has introduced a product that is viable for most data centers right now: the EXPRESSvault EV3.

Conventional Storage QoS falls short on VMware and Virtualized Workloads

Post by George Crump (thank you)

An increasing number of storage systems are coming to market with Quality of Service (QoS) functionality that allows an administrator to guarantee and in some cases, limit the amount of storage performance that a VMware or other virtualized workloads will experience. This is an important feature as the number and variety of workloads continues to increase in the data center. QoS should allow mission critical workloads to be intermixed with less critical workloads, without fear of the impact of a noisy neighbor stealing all available storage performance.
