Comparison between the DL585 G7 and G6 servers
The DL585 G7 offers multiple enhancements compared to its predecessor. They include:
Processors – The DL585 G7 supports up to 48 cores (12 cores per CPU) compared with
the 24 cores supported on the G6, allowing for better performance of multi-threaded
applications and more resources for virtual machine operations.
Memory - The DL585 G7 has twice the number of memory channels and an increase in bus
frequency compared to the G6. This more than doubles the bandwidth of the memory
subsystem. In addition, by supporting low-voltage memory, the DL585 G7 reduces power
consumption over previous generations.
Expansion Slots - The DL585 G7 chipset features PCI Express Gen 2.0. This achieves
twice the bandwidth when compared to PCI-Express 1.1 in G6. The DL585 G7 supports up to
11 I/O slots with dual IOH. It also supports up to four 300 W Graphic Cards and GPGPUs.
The G7 also features a modular I/O subsystem (base I/O feature set, plus an I/O expansion
module) for more choices in configuration. The DL585 G7 has the standard 5-slot PCI-Express
I/O. You can upgrade the server using the optional 6-slot PCI-Express or PCI-X modules for a
maximum number of 11 slots.
Storage Controller – The DL585 G7 has an integrated Smart Array P410i storage
controller, instead of the PCIe card version used on the G6. The DL585 G7 comes standard
with Flash-Backed Write Cache (FBWC), eliminating worry about losing data with loss of
battery power.
Network Controller - The DL585 G7 provides two more embedded 1 gigabyte (GbE)
Ethernet NIC ports for a total of four. An optional NC524SFP module will upgrade two of the
ports to 10 GbE without requiring the use of an onboard I/O slot.
Redundancy - The DL585 G7 supports up to four hot-plug fans and up to four HP common-
slot power supplies providing N+1 redundancy.
