1. xSeries 250 contains an Ultra2 hot-swap, split backplane which supports Ultra160 HDDs at Ultra2 bus
speeds when connected to the standard integrated storage controller. Ultra160 bus speeds are supported with
the addition of an optional Ultra160 storage controller.
2. xSeries Ultra160 SCSI Repeater Card kit includes a jumper cable and installation hardware. This option is
used to convert the standard split backplane into a single SCSI channel supporting up to 10 HDDs.
3. Not supported by the onboard external SCSI port. To configure one of the SCSI storage devices listed here,
select an optional SCSI controller then refer to Appendix D: Cables - Storage Units - Controllers to confirm that
the controller supports the desired External Storage Expansion Unit and to select a supported cable. For HDD
or other expansion unit options, see the specific expansion unit section. For Fibre Channel storage devices,
refer to the Fibre Channel Solutions Overview section.
4. EXP300 includes a single 2M Ultra2 SCSI cable and dual hot-swap 500W power supplies, each with its own
power cord. To convert an EXP300 to a tower form factor, Netfinity EXP300 Rack-to-Tower Conversion Kit (P/N
09N7296) is required.
5. FAStT EXP500 Storage Expansion Unit (P/N 35601RU) includes dual hot-swap 350W power supplies, each
with its own power cord.
6.The FAStT200 includes two hot-swap, 350W auto-ranging redundant power supplies, each with its own power
cord.
7. Can be upgraded to FAStT200 HA Storage Server through the addition of a FAStT200 Redundant RAID
Controller (P/N 19K1121).
