IBM Systems Agenda

The philosophy behind the design of the HS21 and the various BladeCenter Chassis involves four major aspects, Openness, Collaborative Innovation, Virtualization, and Technology Innovation that Matters:

• Unlike competitive blade solutions, many parts of the BladeCenter specifications have been made open. Hundreds of vendors have downloaded the specifications, and dozens so far have released products designed specifically for BladeCenter, including Brocade, Topspin, Cisco, Nortel, Emulex, and others. This provides a wider selection of options to better fit your needs than a purely proprietary offering could.

• IBM has collaborated with industry leaders to offer innovative solution packages for specific industry segments, including banking, retail, telco and others. In addition, IBM formed Blade.org, a planned collaborative organization, to focus on accelerating the expansion of solutions for BladeCenter. Founding members in the blade.org community include Brocade, Citrix Systems, Intel Corporation, Network Appliances, Nortel, Novell and VMware.

• IBM offers virtualization capabilities in a number of ways: desktop virtualization via Hosted

Clients, InfiniBand virtualization and native blade virtualization.

	• Technology for technology’s sake is pointless. Instead IBM BladeCenter focuses on technological
	innovation that provides real customer benefits. Examples of this include a high degree of blade
	and module compatibility across all chassis, the use of fewer and lower-power components to
	enable significant power and cooling savings, and hot-swap and redundant components that
	reduce single points of failure.
Key Features	Intel Xeon Processors
	The HS21 supports up to two identical Xeon processors (that is, the same clock rate and cache
	size and the same number of cores). The choice of processors includes:
	• 80W quad-coreXeon processor models 5310, 5320, and 5345 at 1.6, 1.86, or 2.33GHz
	(respectively), with 64-bit extensions, reduced power draw, a 1066MHz (1.6 or 1.86GHz) or
	1333MHz (2.33GHz) FSB, and 8MB of shared L2 processor cache; supported in all BladeCenter
	chassis.
	• 80W dual-coreXeon processor model 5160 at 3.0GHz, with 64-bit extensions, low power draw, a
	1333MHz FSB, and 4MB of shared L2 processor cache; supported in all BladeCenter chassis.
	• 65W dual-coreXeon processor models 5110 or 5120 at 1.6 or 1.86GHz (respectively), with a
	1066MHz FSB, or models 5130, 5140, or 5150 at 2.0, 2.33, or 2.66GHz, with a 1333MHz FSB.
	These processors feature 64-bit extensions, impressive performance/watt and 4MB of shared L2
	processor cache. Select models also feature an embedded processor with long life support as well
	as NEBS 3/ETSI compliance. Supported in all BladeCenter chassis.
	• 40W dual-coreXeon processor model 5148 at 2.33GHz, with 64-bit extensions, ultralow power
	draw, a 1333MHz FSB, and 4MB of shared L2 processor cache; supported in all BladeCenter
	chassis.
	• 35W dual-coreXeon processor model 5138 at 2.13GHz, with 64-bit extensions, ultralow power
	draw, a 1066MHz FSB, and 4MB of shared L2 processor cache; supported in all BladeCenter
	chassis. This processor is a long-life, embedded offering, intended for a NEBS environment.
	The dual-core Xeon processors contain two complete processor cores; quad-core
	processors, similarly, contain four cores. The processors also contain one unified shared 4MB
	(dual-core) or 8MB (quad-core) cache. The shared cache is dynamically allocated between the
	cores as needed. The two cores appear to software as two physical processors. The dual-core
	processors offer considerably higher performance than a same-speed Xeon processor with a
	single core. Likewise, quad-core processors offer considerably higher performance than a
	same-speed Xeon processor with dual cores.
	Intelligent Power Capability powers individual processor elements on and off as needed, to
	reduce power draw.
	Intel Extended Memory 64 Technology (EM64T) 64-bit extensions allow Xeon processors to
	use large memory addressing when running with a 64-bit operating system. This can result in
	higher performance. Additional registers and instructions (SSE3) can further boost performance
	for applications written to use them. Contact your software providers to determine their software
	support for EM64T.
	DDR II ECC Fully Buffered Memory with Chipkill Protection
