With lot of enterprise SSDs in the market today, one question in the storage admins mind is,
what performance benefits do I get, if I connect SSDs to my ESX servers.
Sadly ESX40 and ESX4.1 do not distinguish between a LUN backed by SATA disks or SSD.Hence when SSD backed LUNs are presented to ESX server, ESX makes no effort to either use the high performace SSD disks or communicate the information to VC that, the LUNs which are presented by array are actually backed by SSDs.
Presence of SSD can essential help servers in many ways.
ESX can use the SSDs to store VM related information like swap files.This will essential improve VM performance. Other uses can be improve the boot time of ESX.
With SSD support from ESX, usecases in virtualized environment are immense. Its just matter of time before everyone would see what VMware has to offer around SSDs.
