Im looking at setting up high availability in our ESXi environment and am looking at PetaSAN as a storage solution but have a few questions.
Ideally I'm looking to have 2 (with the option to expand to 3 or 4 at a later date) fully replicated environments setup for disaster recovery and business continuity.
These environments will be located in different data centers with the idea of having 1 DC live and the second as a failover location, with more failover locations possibly added at a later date.
The plan at the moment is to have 2 to 3 compute nodes and 1 storage node per location all replicated in real time.
Im fortunate enough that I work for an ISP so i have the option to dedicate either 10 or 100 gig of darkfibre between our DC's.
Would PetaSAN work in a setup like this to allow for instant failover in the event of a storage or compute node failure?
Many thanks,
Rob

The short answer is yes but also no.
Yes Petasan will work and can be replicated but no it does not manage fail-over at this time. Your ESXi system can fail over to different SAN networks but that is kind of complicated. There are ways to make this work but it will have to be outside of Petasan.
For replication, you will need a 10Gbps link between clusters to get near real time replication and the initial replication will take a long time as it is a shard by shard replication, but once done its just the deltas that are sent.
