[Dovecot] OT: SAN vs Flash only SAN-less VM architecture for data storage

[Charles Marcus]

Hello all,

I am investigating options for leveraging our companies two locations, 
to provide fault tolerance/redundancy for our VM infrastructure.

I was looking at SAN storage options, but ran across an interesting 
article, and would like opinions. It sounds great, a real win-win as to 
cost *and* performance...

We have redundant/identical hosts at each location that can fulfill the 
requirements discussed...

Stan, I'm especially interested in your take, considering your 
experience with high end SANs and VM storage environments...

Thanks,
