With features equal to standard 1U rack mount servers, the 2 processor, dual-core or quad-core BL460c combines power-efficient compute power, and high density with expanded memory and I/O for maximum performance. The BladeSystem c7000 enclosure supports up to 16 BL460c server blades, 2 more servers than the IBM BladeCenter and each BL460c supports double the memory capacity of the HS21 server without their expansion blade. Now with Quad-Core and Dual-core Intel Xeon processors, DDR2 Fully Buffered DIMMs, Serial Attached SAS or SATA hard-drives, support of Multi-Function NICS and multiple I/O cards, the BL460c provides a performance system ideal for the full range of scale out applications. In this small form factor, the BL460c includes more features to ensure high-availability such as hot-plug hard drives, mirrored-memory, online spare memory, memory interleaving, embedded RAID capability, and enhanced remote Lights-Out management.
