Uniprocessor systems with basic server-class features serve many purposes. For small businesses, uniprocessor systems fit within budget constraints. For mature businesses of any size, uniprocessor systems can provide an ideal fit for server appliances. For all businesses, server-level uniprocessor systems deliver greater reliability, availability, and scalability than otherwise equivalent desktop systems. For any business seeking a cost-effective server-level system for entry-level applications and server appliances, Intel offers the Intel Entry Server Board SE7221BK1-E and Intel Entry Server Platform SR1425BK1-E. The Entry Server Board SE7221BK1-E accommodates one Intel Pentium 4 processor for high levels of overall performance. The board also provides up to 4 GB of dual-channel ECC DDR2 SDRAM and supports the next-generation PCI Express I/O interconnect technology. For enhanced availability and manageability, the Entry Server Board SE7221BK1-E supports Intel Server Management 8 software, hardware, and utilities as well as a number of Intel server technologies expressly designed to simplify administration and maintenance. In addition, Intel has combined the Entry Server Board SE7221BK1-E with the cost-effective Intel Entry Server Chassis SR1425-E (not sold separately) to make the Intel Entry Server Platform SR1425BK1-E. This platform provides a powerful, versatile, and cost-effective rack-mount 1U system.
