storage, or I/O option blades. With the advent of the high-density compute blades such as the ProLiant BL2x220c, up to 32 server blades - each with 2 processors and up to 32 GB of memory for the G5 product - can be housed in a c7000 enclosure. The BladeSystem c-class architecture also provides scalable bandwidth. The NonStop signal midplane is capable of conducting extremely high signal rates of up to 10 Gb/s per lane (that is, per set of four differential transmit/receive traces). For example, in a c7000 enclosure fully configured with 16 halfheight server blades, the aggregate bandwidth is up to 5 Terabits/sec across the NonStop signal midplane.6 This is bandwidth between the device bays and interconnect bays only. It does not include traffic between interconnect modules or blade-to-blade connections. Using Virtual Connect Enterprise Manager (VCEM) software, administrators can scale server blade management by pooling multiple enclosures and managing them together. VCEM is a software application that provides management capabilities for up to 150 BladeSystem enclosures. VCEM provides a central console to perform efficient administration of LAN and SAN connections, groupbased configuration management, plus the rapid assignment, movement and failover of server-tonetwork connections and their workloads. Resilience and availability BladeSystem c-Class enclosures employ multiple signal paths and redundant hot-pluggable components to provide maximum uptime for components in the enclosure. Independent signal and power backplanes enable scalability, reliability, and flexibility. The NonStop signal midplane and separate power backplane have no active components (Figure 5). Separating the high power delivery in the backplane from the high speed interconnect signals in the midplane results in minimal thermal stress to the signal midplane and high reliability. Figure 5.
