Hey Nux, I have worked with a DAS before (albeit DELL), it depends on how it is segregated, in my case, I used it for Exchange and it was seen as shared storage.
If you are looking for performance, you have 12Gbps in total, but you might want more. What configuration were you looking at? Throughput, I/O, Host count etc?

What you need is something like EMC ScaleIO or VMware VSAN that leverages DAS but replicates over the network for resiliency and scale.

Vadim, Let's say this http://www.supermicro.co.uk/products/chassis/3U/836/SC836BE2C-R1K03JBOD.cfm plus a LSI Megaraid card. It has 8 x Mini-SAS ports that I can connect hypervisors to, but from what I read and from what Simon says ( :> ) that doesn't give me shared storage unless I re-export it from another computer. Doing this beats the purpose in a way, because I wanted speed.. If I go over the network I lose that. So it starts to be clear to me DAS is not what I need. :) Lucian -- Sent from the Delta quadrant using Borg technology!
