depending on your system configuration, four or six pci-x slots are available. the slots are 64-bit capable at 133 mhz, 3.3 volts. if your system has four pci-x slots, use slots 3 and 4 with pci adapters that require high performance. use slots 1 and 2 with pci adapters that do not require high performance. all slots are capable of using the full-length pci-x adapters. the pci-x slots are numbered on the rear of the chassis, from left to right.
when equipped with power4+ processors and a six-slotted pci riser card, the model 6c4 and model 6e4 include six hot-plug pci-x slots, dual integrated ultra3 scsi controllers, dual 10/100 mbps integrated ethernet controllers, and four front-accessible disk bays supporting hot-swappable disks. these disk bays can accommodate up to 587.2 gb of disk storage using 146.8 gb ultra3 scsi disk drives. two media bays are used for a cd-rom, dvd-ram, dvd-rom, or another optional media device, such as a tape or diskette drive. the converged service processor 2 (csp), including system power control, is also integrated, along with the native i/o functions such as serial ports, keyboard, and mouse. also included are an enhanced i/o subsystem with the implementation of the remote i/o (rio) interconnect and pci-x bus protocols.
the model 6c4 can support up to two high-density 7311 model d20 i/o drawers to provide additional pci-x slots and disk drive bays. a fully configured system with two i/o drawers has 20 pci-x slots and 4.1 tb of disk space. optionally redundant hot-plug cooling fans and power supplies are available.
all pci-x slots can run 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 following illustration shows the pci adapter slot locations when viewing from the rear of the system.
processors
1 one-way and 2-way processor cards with the gp 1.0 ghz power4 microprocessors with 32 mb of l3 cache per processor card. only a single 1-way card is allowed per server at a time. a 3-way configuration is not supported.
2 one-way and 2-way processor cards with the gq 1.45 ghz power4+ microprocessors with 8 mb of l3 cache per processor card. only a single 1-way card is allowed per server at a time. a 3-way configuration is not supported. power4 and power4+ cards cannot be intermixed.
3 a 1-way to a 2-way upgrade is available by feature conversion.
4 a power4 to power4+ upgrade is available by feature conversion and requires the redundant cooling option, a 6-slot riser card, and a rio-enabled planar.
5 l3 cache capacity per processor configuration:
1 one-way configuration = 1 l3 chip with an 8 mb memory capacity
2 two-way configuration = 1 l3 chip with an 8 mb memory capacity
3 four-way configuration = 2 l3 chips per processor, each with 8 mb memory (32 mb memory capacity)
memory
1 1 gb to 32 gb ecc (error code correction) ddr (double data rate) sdram (synchronous dynamic random-access memory).
2 memory dimms plug into the processor cards (8 dimm slots per card).
3 dimms must be populated in quads (four dimms). a memory feature consists of a quad. additional quads can consist of any memory size.
4 a system with a single processor card (1-way or 2-way) can have a maximum of 16 gb of memory.
media drives
typical system configuration consists of two media bays. one of the media bays can be configured with either ide cd-rom or ide dvd-rom.
1 media bay 1 can accommodate an ide cd-rom or ide dvd-rom.
2 media bay 2 can accommodate a scsi dvd-ram, diskette drive, or tape drive.
the scsi dvd-ram can read cd-rom installation media.
the following media drives are available for the model 6c4 and model 6e4.
1 diskette drive
2 dvd-ram drive 4.7 gb capacity
3 650 mb ide 48x cd-rom drive
4 4.7 gb ide 16x/48x dvd-rom drive
5 80/160 gb vxa tape drive
6 8 mm 60/150 gb tape drive
7 4 mm 20/40 gb tape drive
hot-pluggable disk drives
four hot-plug disk-drive bays:
1 18.2 gb to 587.2 gb of disk storage
2 the following disk-drive sizes and speeds are available:
1 18.2 gb ultra3 10k rpm 1 inch
2 36.4 gb ultra3 10k rpm 1 inch
3 73.4 gb ultra3 10k rpm 1 inch
4 146.8 gb ultra3 10k rpm 1 inch
5 36.4 gb ultra3 15k rpm 1 inch
6 73.4 gb ultra3 15k rpm 1 inch
