IBM BladeCenter HS21 blade delivers competitive performance on SPEC
CPU2000
November 22, 2006 ... IBM® BladeCenter® HS21 blade servers, coupled with the BladeCenter
chassis, deliver advanced application serving with performance, density, and scalability ideal for
enterprise environments.
The IBM BladeCenter and BladeCenter HS21 offerings combine high-density design points with
high performance and advanced server functions. These dense products can double the
processing power within a rack space over 1 U thin servers with rich systems management and
control.
The HS21 blade server has demonstrated competitive performance on SPEC CPU2000, which
comprises the SPEC CINT2000 and SPEC CFP2000 benchmark suites. These results were
achieved using Microsoft® Windows® Server 2003 (32-bit).
The scores in the following table are the first SPEC CPU2000 results published for the HS21
blade models using the Quad-Core Intel® Xeon® Processor E5320 (1.86GHz, 8MB advanced
transfer L2 cache, 1066MHz FSB) and the Quad-Core Intel Xeon Processor E5345 (2.33GHz,
8MB advanced transfer L2 cache, 1333MHz FSB).
