Overview 11
• Improved XenServer updates — To improve reliability of software
upgrades, the XenServer Dell Edition image contains a primary and
secondary copy of the XenServer file system. At any time when an update
is applied, only the secondary copy is updated, leaving the primary copy in
a known good state. The secondary copy now becomes the primary image.
You can update the XenServer host by using the XenServer local console or
XenCenter.
NOTE: You can upgrade the XenServer host to release 5.5. For instructions
on upgrading XenServer Dell Edition, see the XenServer Dell Release
Notes available on the Citrix XenServer Dell Edition website located at
citrix.com/xenserver/dell.
• Pre-certified and supported configurations — XenServer Dell Edition is
certified and supported by Dell for select system and storage
configurations.
