dovecot - Jul 2013 - OT: SAN vs Flash only SAN-less VM architecture for data storage

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,

Until you read the article carefully and note the network requirement:

"Data is synchronously written to another host with a PCIe SSD for data
protection and high availability via a simple, private *10GbE* network."

How about all flash storage like the one from Skyera ?
