System Overview
Processor Overview
Each Intel Pentium
III
Xeon processor is packaged in a single edge contact (S.E.C.)
cartridge. The cartridge includes:
!
The processor core with an integrated 32 KB primary (L1) cache
!
The secondary (L2) cache
!
A thermal plate
!
A back cover
Each processor implements the MMX™ technology with streaming SMID extensions
and maintains full backward compatibility with the 8086, 80286, Intel386™,
Intel486™, Pentium, and Pentium Pro processors. The processor's numeric coprocessor
significantly increases the speed of floating-point operations and complies with
ANSI/IEEE standard 754-1985.
Each S.E.C. cartridge connects to one of two processor mezzanine boards through a
330-pin Slot 2 edge connector (SC330.1). The cartridge is secured to the mezzanine
carrier by a retention mechanism. Each mezzanine board connects to the profusion
carrier. Depending on configuration, your system has one to eight processors.
The processor external interface is multiprocessor (MP)-ready and operates at 100
MHz. The processor contains a local APIC unit for interrupt handling in MP and
uniprocessor (UP) environments.
The L2 cache is located on the same die as the processor core and L1 cache. The cache:
!
Is offered in 1 MB and 2 MB configurations
!
Is ECC protected
!
Operates at the full core clock rate
Memory Overview
Main memory resides on two add-in boards, called memory modules. Each memory
module contains slots for 16 DIMMs and is attached to the profusion carrier through a
300-pin connector on the midplane. The memory controller supports PC 100-registered
SDRAM DIMMs. Various DIMM sizes are supported, but each DIMM must be at least
128 MB. Memory amounts from 128 MB to 16 GB per module are supported. The
ECC used for the memory module is capable of correcting single-bit errors (SBEs) and
detecting 100% of double-bit errors over one code word. Nibble error detection is also
provided.
You can install:
!
From 1 to 32 DIMMs (total number of DIMMs for two memory modules)
!
Equal number of DIMMs on each memory module (except when only one DIMM is
used)
