The Evolution of Solid State Arrays

In the first wave of solid-state storage arrays, we saw commodity style SSDs (solid state drives) being added to traditional storage appliances.  This solution provided an incremental benefit in performance over spinning hard drives, however the back-end technology in these arrays was developed up to 20 years ago and was purely focused around driving performance… Read more »

VMware vVOLS – More Than Just Individual LUNs?

During the VMware keynote session today there was a minor discussion on the upcoming concept of VMware vVOLS.  Today, a virtual machine sits on a VMFS created on a storage LUN or on an NFS share.  An individual virtual machine consists of many files and in the case of VMFS-based VMs, is sitting on a… Read more »

Primary Storage De-duplication: Only for SSD Arrays?

I recently wrote an article for TechTarget that looked at the implementations of data de-duplication in primary storage arrays.  One of the things that stood out for me was the lack of de-duplication support in traditional (and some might say legacy) storage arrays. The cynical amongst us would say that the big 5 storage vendors… Read more »

Enterprise Computing: The Slow Demise of The Hard Drive

Yesterday Nimbus Data Systems announced the release of their S-Class storage array.  What’s different about this storage device is that it uses purely NAND memory rather than traditional spinning disk.  With it’s arrival, we’re seeing another nail in the coffin of the traditional hard drive. OK, so the S-Class isn’t going to replace hard drives… Read more »

Enterprise Computing: Thin Provisioning and The Cookie Monster!

The Gestalt IT Field Day was a great success in bringing together a mixture of delegates from varying discplines. Following the presentations from 3Par and Symantec, there was heated debate about the implementation of Thin Provisioning and the ability to reclaim released storage resources. This post covers the basic concepts of Thin Provisioning and more… Read more »

Whatever Happened to Hybrid Drives?

Over 18 months ago, I discussed in a post (here) the Hybrid Storage Alliance who were looking to increase the performance of hard drives by adding large amounts of flash to each device. But where are they now? A quick check on their website shows precious little information. In fact what’s on offer seems to… Read more »
