High Availability – Citrix Machine Creation Services vs Provisioning Services

My blog post from last week on Machine Creation Services, Provisioning Services, and vSphere Content-Based Read Cache caused quite a few tweets back and forth between those in the Citrix community and I thought I’d continue our discussion with a tweet I posted last week, “PVS less highly available than MCS“.

VMware vSphere CBRC removes the need for Citrix Provisioning Services

I know this will be a sensitive topic among some Citrix folks…but I personally dislike the product (Citrix Provisioning Services).

VMware Changed Block Tracking (CBT) and NFS uh oh!

Saw some twitter activity on this tonight and I knowing we work with many NetApp customers on VMware vSphere I figure this has probably already come up or will soon.
