We are running one ESXi host with a mixture of live and test servers. Hardware is an HP DL360 G6 with 4 SAS drives.
Our aim is to purchase another server (DL380G6) to run another host ESXi server and a separate (preferably HP) storage unit to host the images and share them across both servers.
I have contacted our suppliers and have been recommended several different HP StorageWorks products, however they do not seem to be able to adequately explain the difference between the various types and whether we need DAS/NAS/SAN/iSCSI etc -what each type can achieve for us and ideally which one can also enable us to share storage amongst all servers on our LAN (not just virtual machine images)?
Thanks for your help
