We are regularly told that checking our own bodies for signs of change is a good thing.  Early diagnosis of disease gives more of a fighting chance of curing the problem.  So, in the IT world, where we assume all of our backups have been taken successfully, how often should we be checking the results and ensuring the backup will work on the fateful day we need to do a restore?  This question was posed by Federica Monsone on Twitter this week.  Here’s an attempt to provide an answer. First of all, let’s consider the whole point of taking backups.  Excluding the inappropriate use of backup for archiving, the backup process is there to ensure you can maintain continuous access to your data in the event of unforseen circumstances.  Usually (but not exclusively) these are data loss due to equipment or power failure, data corruption (whether software bug or malicious), a...

HP Challenges Dell for 3PAR

So there we have it.  A week after Dell announce their intention to acquire 3PAR, HP put their cards on the table and trump the Dell bid with an updated offer of $24 a share.  This represents a 1/3 increase over the Dell $18/share offer. HP have been pretty acquisitive in the storage arena over the last few years, acquiring LeftHand, Ibrix and others.  Why now would they want to acquire 3PAR? Defensive positioning – 3PAR being acquired by any of the major vendors could weaken HP’s position in the mid-to-enterprise market.  EVA is a fading product and unlikely to be the first ch... (more)

Two Weeks in Review

It’s been a busy couple of weeks for me, with two lots of travelling in different directions.  Last week I was in Barcelona at the HP Converged Infrastructure (CI)Event and the week previously at HDS’s launch of the new VSP (Virtual Storage Platform).  Both HP and HDS released their new platform at the same time (HP as the P9500, HDS as the VSP) and both originate from Hitachi in Japan.  As is usual with these releases, both companies claim to be integral to the product’s development and perhaps they were in different areas.  Lots of other things have been happening too. The Ris... (more)

Virtualization and Storage: Overview, Vendor Solutions

There’s no denying that virtualization platforms such as VMware and Hyper-V have revolutionized the way in which computing resources are deployed. Physical servers were usually under-utilized and took time and effort to deploy. These servers also consumed data center space, power and cooling. Virtualization reduced hardware costs, reduced the environmental requirements by saving on power and cooling and improved the utilization of physical hardware in comparison to dedicated server environments.

APIs: Essential for Delivering Storage in Enterprise Cloud Infrastructures

It’s pretty easy to pick holes in the current legacy storage products, especially when it comes to integration within both public and private cloud deployments.  However it’s worth discussing exactly what is required when implementing cloud frameworks, as the way in which storage is deployed is radically different from the traditional model of storage operations.  In this post we will look at why traditional methods of storage management need to change and how that affects the way in which the hardware itself is used.  This leads to a discussion on APIs and how they are essential...
