MISCELLANEOUS TECHNICAL NOTES

The IFT-3102 is a Wide-SCSI to Wide-SCSI RAID controller which provides RAID 0, 1, 3 or 5 independently of the host system’s operating system. The controller also comes with Ultra Wide single-ended upgrade board (IFT-9073UWS - diagram not available) and Ultra Wide differential upgrade board (IFT-9072UWD) - diagram not available.
