1-16 System Overview

SAF-TE LOGIC

NOTE: SAF-TE Logic is in systems that include the hot-swap SCSI disk drive cage. SAF-TE Logic is not available in systems that include the standard SCSI disk drive cage.

The SCSI backplane includes SAF-TE (SCSI Accessed Fault Tolerant Enclosure) logic that provides an interface to the disk subsystem that supports status signals, hot swapping drives, and enclosure monitoring.

The transport mechanism for the standardized alert detection and status reporting is the SCSI bus. Disk drives, power supplies, cooling fans, and temperature are continually monitored and the conditions then reported over the SCSI bus to the system. When used with RAID management software the user can be alerted of impending or imminent disk conditions requiring attention. This allows the user to react to conditions that could normally go unnoticed until data loss.

SYSTEM BOARD FEATURES

The following subsections describe the major components of the system board. See "System Board" earlier in this chapter.

Processor

The system board accommodates one or two Intel Pentium III processors with 512k cache in the FC-PGA2 package. This processor uses the .13 micron technology and offers advanced performance. The processor external interface operates at a maximum of 133 MHz.

Memory

The system board contains six 168-pin DIMM sockets each supporting 72-bit ECC (64-bit main memory plus ECC) registered SDRAM DIMMs (PC-133 compatible). Memory is two-way interleaved and partitioned in three banks. You may install a minimum of 256 MB (128MB × 2) and as much as 6 GB.

The controller automatically detects, sizes, and initializes the memory array, depending on the type, size, and speed of the installed DIMMs and reports memory size and allocation to the server via configuration registers.

NOTE: Use DIMMs that have been tested for compatibility with the server board.

Contact your service representative or dealer for a current list of approved memory modules.
