1-2 Motherboard
Features
At the heart of the SuperServer 5025B-4/5025B-T lies the X7SB4/X7SBE, a single
Intel Xeon processor motherboard designed to provide maximum performance.
Below are the main features of the X7SB4/X7SBE. (See Figure 1-1 for a block
diagram of the chipset.)
Processors
The X7SB4/X7SBE supports single Intel Xeon 3200/3000 Series LGA775 proces-
sors at system bus speeds of 1333, 1066 and 800 MHz. Please refer to the mother-
board specifi cations pages on our web site for updates on supported processors.
Memory
The X7SB4/X7SBE has four 240-pin DIMM slots that can support up to 8 GB of
unbuffered ECC DDR2-800/667 SDRAM.
Onboard SCSI (5025B-4 only)
Onboard SCSI is provided with an Adaptec AIC-7901 SCSI controller chip, which
supports dual channel, Ultra320 SCSI at a burst throughput rate of 320 MB/sec.
The X7SB4 provides one SCSI port.
Note:
The operating system you use must
have RAID support to enable the hot-swap capability and RAID function of the
SCSI drives.
Onboard SATA
A SATA controller is built in to the ICH9R portion of the chipset to provide support
for a six port, 3 Gb/sec Serial ATA subsystem, which is RAID 0, 1, 5 and 10 sup-
ported. The SATA drives are hot-swappable units.
Note:
The operating system
you use must have RAID support to enable the hot-swap capability and RAID
function of the SATA drives.
PCI Expansion Slots
The X7SB4/X7SBE has one PCI-Express x8 slot, one PCI-Express x4 slot, two
64-bit 133 MHz PCI-X slots and two 64-bit 100 MHz PCI-X slots (one functions as
a ZCR slot for the X7SB4). An IPMI slot is also included on the board.
