ADIC brings fail-over to SANs

Kevin Komiega

Advanced Digital Information Corp. of Redmond, Wash. released a new version of its CentraVision SAN file sharing system (CVFS). Featuring automated server fail-over technology, the CentraVision is designed to enable sharing of centralized files to network workstations and servers. ADIC is aiming its CentraVision 1.4 at helping to extend the use of SANs to enterprise and Web-hosting applications.

ADIC's director of marketing, Steve Whitner explained that the significant difference over the older version of CentraVision is the inclusion of the fail-over feature.

"Earlier versions have been used primarily by post-production and graphics production houses where data is staged for a short period of time during a specific project, then moved off to some longer term, non-SAN storage," he said. "The new version, with fail-over, makes it more usable for people who want to keep shared data continually available."

CentraVision 1.4 provides automated server fail-over technology, meaning that in the event any server becomes disabled, the central file indexing function is automatically transferred to another server leaving the remaining hosts with uninterrupted access to the centralized files.

The CVFS file sharing system allows UNIX, Windows and Linux hosts to transparently share centralized Fibre Channel disk resources over a high bandwidth SAN. ADIC said that letting different users share storage volumes and even individual files, the CentraVision

enables collaborative workflow and reduces the need for IT departments to duplicate, move, store and manage files.

ADIC gained the CentraVision file-sharing technology in September of 1999 when it acquired MountainGate Imaging Systems Corp. MountainGate specializes in providing software for high bandwidth cross-platform file sharing in Storage Area Networks (SAN).

ADIC says that in the new CVFS 1.4 release, the indexing data required to allow hosts to access the centralized files can be automatically replicated and distributed among different SAN servers. In the event that any server becomes disabled or is powered down, the central indexing function is automatically transferred to another server and all the remaining hosts retain uninterrupted access to the centralized files.
