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. OpenStack while interesting, is not yet reliable or streamlined enough for our small team of 4 to implement and manage. XenServer Storage & Filesystems Unfortunately the downside to XenServer is that it’s underlying OS is quite old.
