Technology Overview
Xserve
High-Bandwidth Server
Architecture
The Dual-Core Intel Xeon processor is only part of the Xserve performance story.
Dual independent frontside buses keep data moving in and out of each processor,
and a super-efficient system controller keeps data moving between all subsystems.
Bandwidth is further enhanced by a 256-bit-wide memory controller and a PCI Express
I/O architecture. Together these advanced technologies provide the performance
and throughput for demanding Internet applications, robust network infrastructure
solutions, and high-performance computational clustering environments.
256-bit-wide memory
controller with 667MHz
DDR2 ECC FB-DIMM memory.
Provides up to 21.3GB/s band-
width and up to 32GB capacity.
Two Dual-Core Intel Xeon processors.
Deliver up to five times the performance
of Xserve G5, with each processor having
a dedicated 1.33GHz frontside bus and
4MB shared L2 cache.
2
Dual onboard Gigabit Ethernet.
Provides two independent ports,
as well as hardware support for
VLAN tagging, jumbo frames,
and TCP, IP, and UDP hardware
checksum.
Advanced system controller. Uses a
PCI Express architecture to enable data
to pass directly between subsystems.
Dual PCI Express expansion. Supports
two independent x8 PCI Express cards
with 2GB/s bandwidth per slot; one slot
can be configured to support PCI-X cards.
High-performance 3Gb/s storage
controller. Supports SATA drives or—
for the most demanding applications—
15,000-rpm SAS drives. Delivers up to
3Gb/s of storage performance per
channel and over 2TB of hot-plug
internal storage.
