Enterprise-level computing in a space-constrained setting presents challenges in terms of processing power, memory, networking, I/O, and storage. Organizations in such environments, especially those running Internet, departmental database, data-center, and other high-transaction applications, need a server solution addressing these challenges with high levels of performance, reliability, and manageability. For such organizations, Intel provides the Intel Server Board SE7520JR2. For processing performance, the Intel Server Board SE7520JR2 supports dual Intel Xeon processors with an 800 MHz system bus and the purpose-built Intel E7520 chipset. A reliable high-capacity memory subsystem is provided through support for six dual-channel Registered Error-Correcting Code (ECC) DIMM sockets available in DDR 266/333 and DDR2 400 configurations and with memory sparing and mirroring. The Server Board SE7520JR2 also includes versatile networking through dual integrated Intel PRO MT Server Adapters and flexible and powerful I/O with up to two slots in a 1U system and six in a 2U system.
