Each of the 4-packs supports up to four hot-swappable Ultra3 SCSI disk drives,
which can be used for installation of the operating system or storing data.
The 36.4 GB and 73.4 GB disks have the following characteristics:
򐂰 Form factor: 3.5-inch, 1-inch (25 mm) high
򐂰
SCSI interface: SCSI Ultra3 (Fast 80) 16 bit
򐂰 Rotational speed: 15,000 rpm (disks with 10K rotational speeds from earlier
systems are not supported)
The RIO-2 riser cards are connected to the planar boards. The RIO-2 ports of
each riser card are connected through I/O loops to RIO-2 ports on I/O books in
the CEC. The connectivity between the I/O drawer RIO-2 ports and the I/O books
RIO-2 ports is described in Remote I/O loop.
