Palo Alto-based Legato Systems Inc looks to have won its big break, with Sun Microsystems officially endorsing the company’s Prestoserve software and hardware accelerator for servers that use Sun’s Network File System. Legato introduced the first Prestoserve products a year ago to help tackle performance bottlenecks with the file system; Version 2.0 came out at the end of April (CI No 1,423). Sun announced the licensing deal with a series of other products designed to boost the database and file serving performance of its Sparcserver line. Sun Prestoserve is said to improve response time on a Sparcserver 470 and 490 by up to 75%: it will sell for UKP4,950 and will be available fourth quarter. Also introduced were a new intelligent peripheral interface disk drive subsystem, doubling the input-output transfer rate to 6M-bytes per second on 911Mb 8 IPI disk drives, and a 128Mb memory board to increase maximum memory to 672Mb on Sparcserver 470 and 490 systems, which sells for UKP337,400. The company also reduced the price of its 32Mb memory boards 32% to UKP10,800.
