Needless to say it is new companies that are pioneering Redundant Arrays of Inexpensive Disks – companies like Raidtec Corp of Alpharetta in Georgia, with a Cork, Eire base, which has announced the first in a series of fault-tolerant disk array subsystems: the FlexArray is claimed to make a dramatic breakthrough in RAID disk arrays both in price-performance and future enhancement capabilities, offering in an external drive array subsystem fault-tolerant storage capacity from 1.2Gb to 7.2Gb per six-drive array; it includes Hot Replacement of drives and Hot Replacement of power supplies so there is no need to power down; multiple FlexArrays can be attached to a single host via SCSI II and Fast SCSI connections for storage capacity of up to 28Gb; it supports RAID Levels 0, 1, 3 and 5 with Hot Replacement, and the first models are aimed at NetWare and Unix personal computers with most popular Unix machines plus AS/400 and Macintosh to be supported by year-end; FlexArray is $3,650 for a diskless subsystem, $10,000 for a six disk drive 1.2Gb system.
