Micropolis Corp has announced VideoNet, a software management tool for its AV Server 50, the low-end server targeted at supplying video to networked workstations. The company said the server can deliver 60 video streams via co-axial cable to desktop machines. The AV Server 50 with VideoNet starts at $20,000, includes four MPEG-2 video channels with 6Gb of storage – the equivalent of four hours 30 minutes at 3Mb per second data rate. The disk drive manufacturer has also released the latest version of its Raidware software for its Raidion disk arrays. Raidware 4.X has PCI communications, supports RAID levels 0, 1 and 5 and up to eight independent disk arrays. It also has a disk patrol feature that scans all disks within the drive to check for data corruption. It can also be used to upgrade external disk driver subsystems to RAID disk arrays. Raidware 4.X became available last month as part of the Micropolis LT Series Raidion subsystems and will also be sold separately for $1,000. The Chatsworth, California-based company has also unveiled its first Fast-Wide SCSI-2 Microdisk external storage subsystem. The 16-bit interface is claimed to give users data transfer rates that are up to 40% faster than its 8-bit drives. The 2.1Gb and 4.3Gb Wide Microdisks will ship as standard or customised version for audio and video applications which have a minimum sustained transfer rate of 4Mb per second with a maximum burst rate of 20Mb per second. The 2.1Gb Model MDLT2100W is $1,900, its 2.1Gb Audio/Video counterpart, Model MDAV2100W, is $2,000. The 4.3Gb MDLT4300W costs $2,500 and the 4.3GV Audio/Video version, the Model MDAV4300W, costs $2,600.
