Marathon Technologies, already providing one of the first high availability solutions for XenServer virtual machines (at guest level), managed to further integrate with the Citrix hypervisor.
The two company are now working to include Marathon everRun VM into the XenServer setup, integrate the everRun Availability Center inside XenCenter and transparently synchronize the HA settings into each other console.
It’s not clear if this integration will be provided by a special version of XenServer that only Marathon Technologies can resell (since the company has an OEM agreement in place), or if it will be an out of the box solution for every XenServer solution sold to worldwide customers: the latter case sounds similar to the integration deal that XenSource closed with Symantec for storage management before the Citrix acquisition (a deal still frozen since that time).
