During last week’s HP Discover 2011 event, Nigel Poulton (@nigelpoulton) raised a very interesting point regarding the way VMware potentially intend to control the storage space through VMFS and the apparent contradiction in terms of also pushing off tasks to the storage array through VAAI.  I thought it worth expanding on [...]

By On December 11, 2010 · 5 Comments · In Storage, Virtualisation

By On October 11, 2010 · Leave a Comment · In Virtualisation

I’ve just posted about the SCSI support that enables VAAI features over on my storage blog.  Writing that post got me thinking about the wider aspects of VAAI or at least the reasons for why VAAI is needed.  This in turn spawned a few random thoughts I feel like sharing.
