AT106A HPE Integrity rx2800 i4 Itanium 9560 Processor Kit

AT106A is an Intel Itanium 9560 processor kit for the HPE Integrity rx2800 i4: 2.53 GHz, 8 cores, 32 MB of Level 3 cache and 170 W. This is the highest clock speed of the four Itanium 9500 kits for the server. The spare processor is AT085-69026, an eight core Itanium 9560 (Poulson, 32 MB Level 3 cache, 170 W thermal design power, socket LGA1248).

The spare latch-type heat sink assembly, AH395-67004, has the two locking tabs and the top latch included, and it has to be replaced whenever a new processor is installed.

The server runs one or two processors from the Itanium 9500 series, and frequencies cannot be mixed in a server. Each processor adds a shared last level cache of up to 32 MB, and the total on-die cache reaches up to 54 MB per processor. Memory controllers, two per processor, have an aggregate bandwidth of 34 GB/s read and a 1 MB directory cache.

Processor features include single bit cache error correction, 50-bit physical addressing, 64-bit virtual addressing, Intel Cache Safe Technology, residual error protection for floating point operations and Automatic Process Recovery.
