VMware vSphere and Dell MD3200, and other shared storage options
Posted on 2014-10-03
I've a project coming up with several options and I would like to make sure I get this right. Dell is very naughty with their shared storage hardware where it doesn't permit you to use non Dell disks, I've tried even the same model number of drives but because Dell puts their own firmware, you can't use any other drive then their own. They get a normal SAS drive, mark up 4 times the price and put out in the market.
So, cheap SSD for read only applications on the MD3200 is a no go as I can't use anything that is not sold by Dell. It is a shame, I have Citrix servers here that barely do any read and a couple of RAID10 arrays would do very well.
I could perhaps use Solarwinds iscsi software on a Windows server and share the storage, but this is scsi, hiher latency and gbit network. I have already a DAS device connected through SAS which is a very low latency device.
The virtual SAN from vmware seems quite expensive and not fully matured for proper production use, it would be good to have shared storage across the hosts that is replicated to other hosts so it works as a "shared" storage, but god knows if that works well.
What other options do you guys suggest?
