Figure 7. Optional c3000 K VM Module – K VM menu screen Interconnect options and infrastructure A key component of the c3000 en closure is the I/ O infrastructur e—essentially, a NonStop signal midplane that provides the internal wiring between the server or st orage blades and the interconnect modules. The NonStop signal midplane is an en tire[...]

Figure 8. Diagram of the HP BladeSystem c3000 signal midplane By taking advantage of the similar four-wire differ ential transmit and receive mechanism, the NonStop signal midplane can support either network-semantic protocols (such as Ethernet, Fibre Channel, and InfiniBand) or memory-semantic protocol s (PCIe), using the same si gnal traces. 3 Fi[...]

Figure 9. Logically overlaying physical lanes (r ight) onto sets of four traces (l eft) Each device bay connector has a 100-pin signal connector with 64 high-speed signal pins hard-wired from the device bay connector to the interconnect bay s. This configuration result s in 16 lanes (64 ÷ 4) to each interconnect bay, which provides at least tw o l[...]

Each interconnect module a lso prov ides external connectors that va ry based on the particular design. In the c3000 enclosur e, pairs of single-wid e inte rconnect modules installe d in adjacent horizontal bays provide redundant connectivity for dual-por t interfaces in each device bay. Adjacent interconnect modules also have high-speed cross- con[...]

However, a full-height serv er blade does require a mezzanine card to connect to the direct attach storage blade. The card must be in the Mezzanine 3 connector to al low ful[...]

4x DDR single-port mezzanine ca rd will work equally well in Mezzanine 1, Mezzanine 2, or Mezzanine 3 connectors. Both types of mezzanine cards us e a 450-pin connec tor, enabling up to eight lanes of diff erential transmit and receive signals—in other words, up to two x1 connections, up to two x4 connections, or a single x8 connection. Because t[...]
