Product Positioning

The BladeCenter and BladeCenter offerings are positioned as the highest-density servers of the IBM eServer line. They represent a new approach to the deployment of application servers where two-way, SMP processing, high-availability design, and systems management and easy setup features are combined in an extremely dense package. The JS20 blade is positioned within the POWER product set as the lowest priced two-way POWER-based server from IBM. The BladeCenter packaging with minimal use of power and maximal server density allows the JS20 to provide exceptionally low cost of operation. The common set of management tools with the rest of the BladeCenter product family helps reduce the management cost of the JS20. This combination is designed to give the JS20 exceptional total cost of ownership. The PPC 970 is also the only POWER processor from IBM to have SIMD instructions. This enhancement to the instruction set makes the PPC 970 the preferred choice for applications that can exploit this increased parallelism. The JS20 blade is positioned within the BladeCenter family as the IBM 64-bit processor blade server option. This provides a performance advantage for data intensive applications as well as the applications that exploit the SIMD capability. The BladeCenter in just 7 U of rack space contains up to 14 blade servers and provides the necessary I/O network switching, power, cooling, and control panel information to support these individual servers. When compared to 1 U high servers, the BladeCenter can support twice the number of processors in the same rack space. The BladeCenter and BladeCenter JS20 blades can require less space and power resources because of their high-density design, reduced power requirements, and single environment systems management. This is an extremely important consideration for: Large enterprises Application service providers Scientific and technical computing businesses They are an excellent fit for applications such as: Bioinformatics Seismic Processing Digital Signal Processing Financial Services Collaboration Terminal Serving Dynamic Web Serving Scientific and Technical Computing Linux clusters This BladeCenter JS20 offering enhances the BladeCenter line and offers customers a POWER-based alternative.
