Those of you who attended VMworld this year will remember the stack of servers and storage on display happily serving VM’s to the vistors, exhibitors and Staff at the conference, well one of the key components of that stack was provided by Xsigo. Their product the I/O Director offers signficant savings in large environments by effectively virtualising the I/O stack. I am not going to go into the ins and outs of I/O virtualization in this article. Well it now appears that they are expanding their partnerships.
