My last post on VMware VMotion urged several readers to protest, maybe because of its provocative title. What I did was to compare VMware clustering with Microsoft failover clustering.

And boy, can they come in handy! Continue reading ‘Hard Links, Soft (Symbolic) Links and Junctions in NTFS: What Are They (For)?’
