Microsoft plans to license high-availability storage management software from Columbia Data Products (CDP) to manage network-attached storage. Microsoft will include the software in the Windows 2000 Server Appliance Kit.

CDP’s Persistent Storage Manager (PSM) has been optimised to work tightly with the Windows 2000 Server Appliance Kit, ensuring a stable and secure environment that will scale to include storage management capabilities required by OEMs.

IBM and NEC will release NAS appliances, based on the Microsoft Windows 2000 operating system and CDP’s PSM, creating high-availability systems that compete with storage servers costing significantly more, CDP said. Customers will benefit because these products use industry standard hardware and software platforms, thus eliminating the need to buy additional data protection hardware or software, except for archival purposes, CDP said.

"Data protection is a key feature for OEMs building NAS appliances," said Keith White, Director of Marketing for the Embedded and Appliance Platforms Group at Microsoft. "By licensing CDP’s data protection software for inclusion in the Microsoft Server Appliance Kit, server appliance manufacturers can quickly and easily bring powerful NAS appliance offerings to market."

PSM creates multiple point-in-time persistent True Images of any or all system and data volumes residing on the NAS. All persistent images survive system power loss or a planned or unplanned re-boot. Each instance of PSM is able to handle 250 concurrent images of up to 255 independent volumes for a total of 63,750 independent data images. Any image can be managed through the web based Server Appliance Kit (SAK) interface, and accessed the same as any other active volume. For disaster recovery in case of data corruption or loss, any volume can be reverted to a prior time from any persistent image, preventing any system downtime. CDP’s PSM always has multiple backups on-line for users to retrieve their own files or just reboot to a "pre-disaster" image eliminating cumbersome, time-consuming, unreliable tape or other hardware, providing cost savings in hardware, software, and support manpower.

PSM is based on CDP's Open Transaction Manger (OTM) technology. OTM currently is the open file option for products such as Veritas’ NetBackup, NetBackup Professional, and BackupExec. OTM's image based approach to open file protection affords users a high level of data integrity, while eliminating the backup window completely. PSM uses the OTM concept but takes it to the next level of data protection by adding data protection features that integrate with Microsoft's Windows 2000 Server Appliance Kit.
