BOX HILL, STORAGETEK, LEGATO OFFER BACK UP OVER SANS.

New York city-based Box Hill Systems Corp teamed up with StorageTek Technology Corp and Legato Systems this week to deliver what they claim is one of the first solutions to enable organizations to perform back-ups over storage area networks (SANs). A SAN is a fibre channel-based, high-speed network, which is separate from the local area network, and supports transfer speeds of up to 200 Mbps. Previously, back-ups have typically been carried out over the Lan, which meant the network had to be taken down and not used for anything else while the back-up was being carried out. In the case of a bank, for example, this could cause a break in service for customers, said Philip Black, CEO of Box Hill, but for any organization having the network off-line is an inconvenience for users. Shifting storage to the SAN allows firms to keep their Lans up and running 24 hours a day; what the three companies are calling "Lanless back-up." Using the SAN allows disk subsystems and tape libraries to be shared among multiple [Unix or NT] servers, thereby reducing hardware costs. Additionally, Lan throughput will not be degraded due to back- ups, and back-ups will be completed faster, with SAN speeds up to and above 100Mbps. As part of the joint initiative, Box Hill will integrate its fibre channel-based line of (RAID) systems (used for local PC or server storage) with Legato NetWorker and Legato SmartMedia backup software alongwith StorageTek's selection of tape libraries, fibre channel disk and networking components. Box Hill will be responsible for providing customer service and support. To make its software operate across a SAN, Legato had to strip out the TCP/IP stack and make it compatible with the fibre channel protocol. "This makes SAN speeds faster," said Black, "it also reconfigured the software so it could be distributed among lots of servers rather than just hung off one, as in the Lan environment." Additionally, multiple PCs can now share one tape library, he added. The Lanless back-up solution is available now and costs around $100,000, depending on the configuration.
