Programmed Logic Corp, the company working to establish a set of modular storage management software for the OEM market (CI No 3,141), has gone to NCR Corp for volume manager software, a hole in its current product line. Programmed Logic will license NCR’s Disk Array Plus product, rename it StackVM, port it to other operating systems, modify it to fit its own stackable component architecture, and then license the enhanced product on to third parties. NCR itself looks likely to take the enhancements. The two firms have been working together for almost a year on the software, with Programmed Logic working to integrate it with its HTFS high throughput file system, and preparing ports to Sun Microsystems Inc’s Solaris and Microsoft Corp’s Windows NT. NCR recently signed up as a Solaris OEM (CI No 3,218). Disk Array Plus, part of NCR’s Lifekeeper range of high availability middleware and clustering software, is the only product Programmed Logic says it could find to compete with Veritas Software Corp’s volume manager, but with the additional ability to replicate disks and logically stack RAID levels over other RAID levels. It previously ran only on NCR’s MP-RAS Unix implementation, and as part of the Santa Cruz Operation’s OpenServer 5.0 operating system, where it has been integrated with the HTFS file system. Programmed Logic will sell it as part of its stackable storage products, including the StakFS file system, HTFS journaling file system and StackOS operating system. The Solaris version is out very soon and the Windows NT port is due in the latter half of next year.
