VMFS Locking Uncovered - vSphere Blog

Finally have time to get something on my blog.

Cormac Hogan from VMware has  a very good blog about VMFS. He starts by general overview on VMFS locking. Which over my time in virtualisation is misunderstood more often than not .

 Areas covered:

  • Heartbeats
  • On-disk Metadata Locks
  • Optimistic Locking
  • VAAI ATS (Atomic Test & Set)
