Why doesn MSCS support Windows NT Server software RAID (“FTDISK”) for disks connected to the shared disk bus?
The current FTDISK capability in Windows NT Server provides excellent, cost-effective protection of disks connected to a single server. However, its architecture is not well suited to some situations that can occur when doing failover of disk resources connected to two servers through multi-initiator SCSI. Microsoft plans to enhance FTDISK in a future release to address this issue. In the meantime, disks connected to a Windows NT Server machine through multi-initiator SCSI can be fully protected by widely available hardware RAID.
