Bus Architecture
Six PCI-X slots are available. Four of these slots (1, 4, 5, and 6) are 64-bit capable at 133 MHz, 3.3 volts.
The remaining PCI-X slots (2 and 3) are 32-bit capable at 66 MHz, 3.3 volts. The slots are numbered on
the rear of the chassis from left to right or top to bottom, 1 through 6.
All 64-bit PCI-X slots are capable of running either 64-bit or 32-bit adapters. However, a 32-bit adapter
operates in a 32-bit mode and shows no performance advantage while running in a 64-bit slot. The
preceding illustration shows the PCI adapter slot locations when viewing from the rear of the systems.
Processors
v
One-way and two-way processor DCMs (double chip modules) are available.
v
An 8 MB L3 cache is contained in the processor DCM.
Memory
v
1 GB to 16 GB ECC (error code correction) DDR (double data rate) SDRAM (synchronous dynamic
random-access memory)
v
Memory DIMMs plug into the system backplane (8 DIMM slots).
v
DIMMs must be populated in quads (a single memory feature contains four DIMMs).
v
Memory quads can be different memory sizes.
v
A system can have a maximum of 16 GB of memory.
Media Bays and Media Backplane
Two slimline media bays and one full-height media bay are provided. The slimline media bays are for IDE
optical devices or diskette drives. The full-height bay is for a SCSI tape drive or DVD-RAM drive.
Note:
The following restrictions apply to the media drives:
1. Media devices are not hot-pluggable.
