Calor Gas has overhauled its storage infrastructure using an end-to-end storage area network (SAN) package from B2net.

The SAN, which uses virtual server technology, has allowed Calor Gas to simplify and integrate its disparate enterprise data storage and back-up systems. The gas supplier is now consolidating 50 of its 90 servers down to just four.

The consolidation tackles the sprawl of the gas firm’s server estate, which included outmoded, disparate servers where applications were isolated or did not sit comfortably alongside one another. The inefficient infrastructure meant available storage could not match growing demand and was costly to maintain.

Calor Gas network manager Andrew Browne said: “The new server approach will enable us to have as close to a 24-7 operation as we can. The aim was to significantly reduce the maintenance we needed to run on the old system in terms of patching, upgrades and downtime.

“By moving to a virtual storage environment, we can maximise storage efficiency and demand and reduce the cost base of the infrastructure. We had to make the project as cost neutral as possible by removing physical barriers and reutilising our newer servers for other projects instead of purchasing new ones.”

The new system includes a Network Appliance 3020 Cluster Server, four VMware virtual servers and PlateSpin technology to convert the servers to virtual storage devices. It also incorporates Symantec’s Enterprise Vault for email and file archiving, NTP Software’s QFS Storage Firewall and Overland Tape Library for back-up.
