Latest XenDesktop 7.5 IOPS


It is amazing when you've been focused on a technology for so long that you start to see major improvements. In 2010, I provided my original guidance on XenDesktop IOPS. Four years later, have we seen any major improvement? See for yourself. As you might be aware, I've been working with the Citrix Solutions Lab… Continue reading Latest XenDesktop 7.5 IOPS

The Latest XenApp 7.5 Read/Write Ratios

Local or Shared Storage – that is the question


Previously I've talked about how using local storage can help reduce the costs of desktop virtualization.  Paul Wilson tested this type of environment to determine if it is possible or to see if I was talking crazy. The result: it is possible and I'm a little crazy.  So we have a new design decision, which… Continue reading Local or Shared Storage – that is the question
