For more details: DataCore Storage Virtualisation and Citrix Xen
'The virtual infrastructure that encompasses both server and storage virtualisation has made my life easier for provisioning new servers and adding disk space,' comments Jeremy Hines, Manager of IS, Evans Fruit Company. 'And it is the total virtualised environment, spanning Citrix Xen and SANmelody that makes this possible.'
"Three Xen virtual hosts, meaning three physical servers, run all of the virtual machines. Two DataCore SANs running on SUN x4250s are physically separated, albeit in the same building, connected to each other via Ethernet. According to the IT staff, SANmelody makes it much easier to add storage to a machine, which is done by carving a new LUN (logical unit number) and then attaching it to the machine. Doing so immediately provides administrators with what amounts to a new hard drive, the size of which is easily increased. Notes Hines, 'You carve out a new LUN, copy the data, and then drop the old LUN. It is pretty straightforward. We really like that in terms of ease-of-use.'"
