applications in High Performance Computing (HPC) and enterprise data centers. Parallel or distributed applications running on multi-processor multi-core servers benefit from the reliable transport connections, and advanced multicast support, offered by ConnectX IB.

End-to-end Quality of Service (QoS) enables partitioning and guaranteed service levels, while hardware based congestion control prevents hot spots from degrading the effective throughput.

NOTE: In order for the 448262-B21 to work in DDR mode on the 410398-B21 HP switch blade, the switch blade's firmware level must be 1.0.0. If the switch blade's firmware level is lower than 1.0.0, the 448262-B21 works only in SDR mode.

For details on how to upgrade the switch firmware on the HP switch blade using itutil, see the itutil discussion in Chapter 6, “Administration and Management”.

•AH304A PCIe adapter with 2 (two) 4X fabric copper interfaces

The AH304A product is for use in high-performance technical computing clusters and in database clusters, and includes features specifically required to support and integrate with the Oracle 10gRAC database. The AH304A can only be installed in supported servers.

•410533-B21 HP 4X DDR IB Single-Port Mezzanine Fabric Adapter is for use in the HP Integrity BL860c Server Blade. It is used in conjunction with the 410398-B21 HP BLc 4X DDR Mezzanine Switch, which is required and embedded in server blade enclosures, such as the C7000. This switch does not provide subnet manager functionality.

•AD313A PCIe adapter with 2 (two) 4X fabric copper interfaces

The AD313A product is for use in high-performance technical computing clusters and in database clusters, and includes features specifically required to support and integrate with the Oracle 10gRAC database. The AD313A can only be installed in supported servers.

•AB286C PCI-X 133Mhz adapter with 2 (two) 4X fabric copper interfaces

The AB286C product is for use in high-performance technical computing clusters and in database clusters, and includes features specifically required to support and integrate with the Oracle 10gRAC database. The AB286C can only be installed in supported servers.
