As most of you know I work for VMware which means I receive a huge amount of email and documents with excellent technical info. Some I can’t blog about but some I can. Last week I received this VMware HA implementations notes document by Seva Semouchin. Seva is a Technical Account Manager based in Germany! This document deals about VMware [...]
