Dell PowerEdge R900: System Features

System Features

The major hardware and software features of your system include:

®

®

• Two, or four Quad-Core Intel

Xeon

Processors 7300 Series.

• Support for symmetric multiprocessing (SMP), which is available

on systems with two or four Intel Xeon microprocessors. SMP greatly

improves overall system performance by dividing microprocessor

operations between independent microprocessors. To take advantage

of this feature, you must use an operating system that supports

multiprocessing.

NOTE: If you decide to upgrade your system by installing additional

microprocessors, you must order the microprocessor upgrade kits from Dell.

Not all versions of the Intel Xeon microprocessor will work properly as

additional microprocessors. The upgrade kit from Dell contains the correct

version of the microprocessor as well as the instructions for performing the

upgrade. All microprocessors must have the same internal operating

frequency and cache size.

• A minimum of 2 GB of 667 MHz, Fully Buffered DIMMs (FBD),

upgradable to a maximum of 128 GB by installing combinations of

512-MB, 1-GB, 2-GB, or 4-GB memory modules in the four memory risers.

• Support for up to five 3.5-inch, internal hot-pluggable SAS

(Serial Attached SCSI) hard drives or support for up to eight 2.5-inch,

internal hot-pluggable SAS hard drives.

• One slimline IDE DVD-ROM/CD-RW drive or slimline SATA

DVD-ROM/CD-RW drive (when available).

• Two hot-pluggable power supplies in a 1 + 1 redundant configuration.

• Four fan modules, each comprised of two dual-rotor fans, for a total

of eight cooling fans.

• Three x4 and four x8 PCI-Express expansion slots.

• I/O Riser card providing four Gigabit Ethernet NICs, capable of

supporting 10-Mbps, 100-Mbps, and 1000-Mbps data rates.

• Dedicated PCI slot for an integrated RAID controller card with 256 MB

of cache memory and a RAID battery.

NOTE: System boot is not supported from an external device attached to

a SAS or SCSI adapter, including SAS 5/E, PERC 5/E. See support.dell.com

for the latest support information about booting from external devices.
