The DD3 ISA RAID 1 disk mirroring controller
mounts into any standard ISA slot and mirrors two IDE drives. Because the device uses the slot for power only and not for data transfer, it is not hampered by
the normal speed limitations of ISA devices. It offers an ideal solution for industrial chassis and for mirroring IDE drives where there is no free PCI slot or
drive bay available. Simply drop the ISA
board in place, connect the supplied cables and
you are ready to enjoy total data redundancy.
The ISA provides back panel status lights,
serial port and alarm reset.
