In the past decade or so, storage management has developed into a discipline in its own right, driven by big increases in the amount of data being stored, as well as the rise of storage networking protocols that facilitate shared storage. Virtualization, meanwhile, has become the foremost technology for server and PC optimization.  In this environment, shared storage provides functionality that would otherwise not be possible, such as nondisruptive virtual machine migration. But virtualization adds a layer of complexity in the association between a server and the storage that supports it. That layer of abstraction between virtualization and storage means it’s a challenge to translate storage-focused concepts such as RAID groups and LUNs to virtual objects such as VMDKs and virtual hard disks. So, to successfully provide storage for virtual environments, storage ad... (more)

Amazon Delivers Cloud Archive Storage with Glacier

At the end of August 2012, Amazon Web Services released their latest service offering – a long-term archive service called Glacier.  As a complement to their existing active data access service S3, Glacier provides long term storage for “cold” data – information that has to be retained for a long time but doesn’t require frequent access. What Exactly is Glacier? Many organisations need to retain data in archive format for extended periods of time.  This is for regulatory or compliance purposes or may simply be part of their normal business process.  Good examples are medical, h...

Optimizing Storage Architectures for SSD

Last week I attended Hitachi’s 2012 Blogger Day.  Aside from catching up with some old friends, we were presented with some NDA stuff which will see the light of day soon.  In the meantime, I want to talk about a press release Hitachi made while I was still on holiday (and clearly missed as I returned, somewhat jet lagged). Previously I’ve discussed how solid-state arrays need to be optimized in their design to get the best out of the technology.  Traditional arrays were designed to cope with the hard drive as the slowest component in the architecture.  IP was built around squee...

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...
