To FT Or Not To FT?


What are the high availability options in a VMware environment?

  1. VMware High Availability (HA) provides high availability.
  2. VMware Fault Tolerant (FT) provides high availability.
  3. Microsoft Clustering (MSCS) provides high availability.

Great! They all provide high availability but I still don’t kow which one to pick up you would say 🙂

You need to ask yourself the right questions:

  1. How long can I afford a downtime?
  2. How complex my high availability setup can be?

Based on that you can choose the righ solution.
For example if I can’t afford a single second of downtime, VMware FT is the solution.
Or if you can afford a few minutes downtime and you don’t want a complex setup, go for VMware HA.
Microsoft Cluster provides a good high availability solution but it is a complex setup and unless it is an active/active setup, it is a waste of processor and memory resources.

Update: Hany Michael @ hypervizor.com just posted a superb article on the subject, worth a read and as usual, Hany’s videos and blue prints are excellent 🙂

Scott Lowe also posted an article on the subject, worth the read! Scott explores the advantages, disadvantages, similarities, and differences of the high availability options available.
