It’s probably fair to say that data migration is one of the most tedious tasks in storage management. Moving data from one array to another, simply to decommission a piece of hardware or for load and capacity balancing, doesn’t ever inspire me. But it’s a necessary evil and one I’ve done many times. Unless the [...]
Last week VMware issued this advisory on their knowledge base, recommending the disabling of VAAI Thin Provisioning reclaim in ESXi 5.0.

VAAI Thin Provisioning is enabled by default [...]
I had a tweet this morning from Leo Tudisca following on from the latest Infosmack Deep Dive podcast discussing storage and virtualisation. Leo’s question was regarding sub-LUN virtual machine replication and how it can be achieved. This requirement is something I’ve been mulling over for some time and can’t remember if [...]
Yesterday HDS announced (via this press release) their entry into the converged infrastructure market. The solution offerings go under the name Hitachi Unified Computing Platform and comprise reference architectures and orchestration software to bring the whole thing together. While I think it is a good thing that HDS are starting to deliver unified [...]
I recently wrote an article covering storage for virtualisation and was surprised to find out that Microsoft does not support the use of NFS shares with Hyper-V. At first I thought perhaps I was doing something wrong and that my configuration was in error. But after a lot of [...]
In my post on last year’s HP tech day (Enterprise Computing HP Blades Tech Day) I raised my skepticism on the ROI of desktop virtualisation or VDI (Virtual Desktop Infrastructure) solutions. One of the reasons for my concern was the excessive costs for deploying the storage needed to support I/O to hundreds [...]
