contain several hundred cores and that the accelerator card may also have several gigabytes of onboard memory. Many accelerator cards use 100 to 300 watts of power, which is significantly greater than the 75 watts of power that is supported through the PCIe x16 connector. Fortunately, the PCIe specification defines a method for supplying additional power to cards using auxiliary power connectors on the system motherboard that connect to the accelerator cards using special cables. Depending on their physical configuration, these cables are capable of supplying an additional 75 watts to 225 watts of power to a PCIe card. HP Product Engineering has specifically added these power connectors to ProLiant systems to support these accelerator cards. Electrical power consumption produces heat, and as a result of their relatively high power consumption high performance visualization/acceleration cards place an additional burden on server cooling systems. HP has designed advanced sensor and fan control systems into G6 ProLiant servers to deliver the most efficient cooling possible and to support the additional cooling requirements of the latest generation of these cards. Capability matrix for HP ProLiant servers Table 1provides a summary of the mechanical, I/O and power support incorporated into HP ProLiant G5 servers to support the use of visualization and acceleration products. Included in this table are the HP option kits for the power cables required to support them in the various servers. Table 1.
