XenServer, SSDs & VM Storage Performance

IntroAt Infoxchange we use XenServer as our Virtualisation of choice. There are many reasons for this including: Open Source. Offers greater performance than VMware. Affordability (it’s free unless you purchase support). Proven backend Xen is very reliable. Reliable cross-host migrations of VMs. The XenCentre client, (although having to run in a Windows VM) is quick and simple to use. Upgrades and patches have proven to be more reliable than VMware.
