Hi, I recently did some benchmarking on a Rackspace VM and was surprised that bonnie++ showed a read throughput of almost 500MB/sec. Does anyone have an idea how they achieve these speeds in a shared environment? While you can achieve this with a RAID easily these days once you have lots of VMs accessing that array I would expect that speed to go down quite a bit. Was I just lucky that I was the only one accessing the disks that way at that moment or how do they keep up with this kind of demand?
Regards, Dennis

Seems like the 2Gbps fibre bandwidth is equally divided into 4 in the SANprovide such speeds. a Very conservative design I suppose.
dunno. Last seen SAN about 6 months ago so memory fades...

You're mixing up units. 2 Gbps means 2 Gbit/sec, which is around 200 MB/sec.

Ooops!
I stand corrected
