Ultra320
A subset of Ultra3 SCSI that allows a maximum throughput of 320
Mbytes/s, which is twice as fast as Wide Ultra2 SCSI. Ultra320 SCSI
provides 320 Mbytes/s on a 16-bit connection.
Virtual Sizing
FlexRAID virtual sizing is used to create a logical drive up to 80 Gbytes.
A maximum of 40 logical drives can be configured on a RAID controller,
and RAID migration is possible for all logical drives except the fortieth.
Because it is not possible to do migration on the last logical drive, the
maximum space available for RAID migration is 560 Gbytes.
Wide SCSI
A variant on the SCSI-2 interface. Wide SCSI uses a 16-bit bus, double
the width of the original SCSI-1. Wide SCSI devices cannot be
connected to a SCSI-1 bus. Like Fast SCSI, Wide SCSI supports transfer
rates up to 20 Mbytes/s.
