thus allowing companies to integrate applications and other data sources. These types of servers benefit from the processing power offered by the x450. The performance of the server shows promise in Web servers that perform secure e-commerce transactions, which is a market segment currently dominated by Sun Microsystems and their SPARC machines. To see Intel's performance comparison of Intel Itanium 2 and Sun UltraSPARC III processors, click Compare processor performance at: http://www.intel.com/products/server/processors/server/itanium2/index.htm When using x450 as a Web server for your e-commerce solutions, you will benefit from its highly parallel computation that can handle higher volumes of secure data transmissions using complex encryption/decryption techniques. The Itanium 2 micro-architecture is a perfect match for the significant compute power requirements of Secure Sockets Layer (SSL), providing protection without incurring delay. SSL uses advanced public key encryption technology to safely move sensitive information across the Internet. In today's complex environments, encryption can occur at two levels simultaneously. For example, the IPsec standard performs encryption on every packet sent over the network. These packets frequently contain data that is encrypted itself. As a result, enterprises need platforms that can encrypt and decrypt data very quickly.
