HP ProLiant DL585 G7 server technology

HP ProLiant DL585 G7 processor architecture
The DL585 G7 servers support four AMD Opteron 12-core 6100 Series processors. AMD 12-core
technology delivers high performance and reduced latency for multi-threaded applications and multi-
tasked environments.
The DL585 G7 servers feature HyperTransport™ 3.0 (HT3) technologies, which provides a direct,
scalable bandwidth interconnection between the processor, the I/O subsystem, and the chipset
(Figure 2). HT3 is an enhancement of HT1, and increases the interconnect rate from two giga-transfers
per second (GT/s) available on previous AMD processors to a maximum of 4.8 GT/s. Each processor
operates at speeds of up to 2.4 GHz, maintains 512 KB of L2 cache memory, and shares a total of
12 MB of L3 cache. An integrated memory controller supports PC3-10600 (DDR3-1333) DIMMs.

HyperTransport™ technology Assist
HyperTransport™ technology Assist (HT Assist) reduces cache probe traffic between processors,
resulting in faster queries that increase performance for cache sensitive applications such as
database, virtualization, and compute intensive applications. HT Assist™ resides in the first 1MB of L3
