Whether you need multiple SCSI host adapters or not depends on the character of the I/O transactions. For random I/O, which resembles a typical news server a whole lot more than sequential I/O, the SCSI bus will not be the bottleneck. This assumes, of course, that the SCSI host adapters you select can keep the drives busy. Leonard
