IBM BladeCenter HS21

High-density, modular blade servers that support the latest Intel® Dual-Core Xeon® processors

IBM HS21 Blade ServerTake advantage of Intel’s dual-core Xeon CPUs with the IBM HS21 blade server. Take advantage of the shared 4MB L2 cache and support for single- and multi-threaded applications. The HS21 also includes high-performance features such as Intel Extended Memory 64 and high-speed fabrics with the BladeCenter H, even thought the HS21 is compatible with the entire BladeCenter chassis family.

The HS21 comes with 1GB memory standard, but you can expand up to 32GB per server. This cutting-edge technology features the same modular architecture designed for maximum compute density, but they also take advantage of new technology to reduce cooling and power costs without sacrificing performance.

Take advantage of technologies like 2Gb & 4Gb Fibre Channel, Gigabit Ethernet, Myrinet, or 1X & 4X Infiniband with the HS21 blade servers expansion PCI slots.
