Chapter 5 Hardware Architecture 5-3
5.2 The AMD Opteron Processor
AMD Opteron processors with Direct Connect Architecture include several new
features, including seamless quad-core upgradability and DDR2 memory. AMD
Opteron processors with DDR2 memory feature a common core architecture that is
consistent across 1-way, 2-way, and 8-way systems. Features of the second
generation 2.2-GHz AMD Opteron include:
■ x64 Architecture (64-bit extensions) with AMD Direct Connect Architecture using
HyperTransport technology supports simultaneous 32-bit and 64-bit computing
■ Three HyperTransport links supporting up to 24 Gbyte/sec peak bandwidth per
processor
■ Integrated 128-bit wide DDR memory controller that reduces latency and
increases performance
■ Individual 1-MB L2 cache per core
■ Low power usage and cooling requirements - AMD Opteron processors running
at 68W offer efficient heat dissipation without reducing performance
■ AMD PowerNow! technology can deliver performance on demand while
minimizing power consumption
■ DDR2-based systems can upgrade to Quad-Core AMD Opteron processors when
they are available, within existing power and thermal envelopes
■ NEBS certified
■ Socket F 1207-pin
The following processors are supported on the Sun Netra CP3220 blade server:
■ CPU, Opteron, Dual-Core, 2.2GH 68 W, NFP
■ CPU, Opteron, Quad-Core, 1.8 GHZ 79W, NFP
