Dataram announced the release of a 16 GB memory upgrade, the DRH8640/16GB, for Hewlett-Packard’s Integrity rx7640 and rx8640 mid-range servers.

Each of Dataram’s DRH8640 memory upgrades consists of a matched pair of 278-pin 533 MHz ECC DDR2 DIMMs developed specifically for the rx7640 and rx8640 servers. High-density 2 Gb DRAM technology makes possible these high-capacity proprietary 8 GB DIMMs.

Memory is installed on one or more HP Cell Boards based on HP’s sx2000 chipset. Each Cell Board contains four Intel Itanium 2 processor sockets and 16 DIMM slots divided into quads. The rx7640 supports one or two HP Cell Boards and a maximum memory capacity of 256 GB. The rx8640 supports one, two or four HP Cell Boards and a maximum memory capacity of 512 GB. These HP servers are ideal as enterprise database servers and are known for their reliability, availability and scalability with large memory configurations.

The minimum memory capacity is 2 GB per Cell Board, configured as 2 x 1 GB DIMMs and installed in echelon 0. The maximim memory capacity is 128 GB per Cell Board, configured as 16 x 8 GB DIMMs. DIMMs of different capacities are supported but the largest capacity DIMMs must be installed first across a Cell, followed by progressively smaller capacities. For the best performance, a Cell should be configured with a multiple of 8 DIMMs (4 pairs) and memory loaded equally across Cell Boards.

In addition to Dataram’s new 16 GB DRH8640/16GB upgrade, 4 and 8 GB product capacities are also available.
