better performance of multithreaded applications and more resources for virtual machines. The Intel® Xeon®
Processor 7500 series support up to 8 cores (16 hyperthreads) per processor.
Memory—With the support for a new Memory Cartridge and 32 GB DDR3 DIMM, the DL580 G7 supports 2TB
of memory capacity. In addition, by supporting low-voltage DIMMs, the DL580 G7 reduces power consumption
when compared with previous generations.
Expansion Slots—The DL580 G7 features PCI Express Gen 2.0. This achieves twice the bandwidth when
compared to PCI-Express 1.1 in G5. The DL580 G7 supports up to (11) I/O slots with dual IOH. It also
supports up to three 300 W Graphic Cards and GPGPUs. The DL580 G7 features a modular I/O subsystem
(base I/O feature set plus an I/O expansion module) for more choices in configuration. The DL580 G7
standard configuration is five PCI-Express I/O slots. Upgrade the server with the optional 6-slot PCI-Express or
PCI-X modules for a maximum number of 11 slots.
Storage Controller—The DL580 G7 has an integrated Smart Array P410i storage controller and comes standard
with Flash-Backed Write Cache (FBWC), eliminating the worries of losing data with loss of battery power.
Network Controller—The DL580 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 I/O slot.
Redundancy—The DL580 G7 supports up to four hot-plug fans and up to four 1200W 94% efficient, common-slot
power supplies. The DL580 G7 offers memory redundancy through memory mirroring, sparing, ECC, Single
Device Data Correction (SDDC), and Double Device Data Correction (DDDC).
