NovaScale R422-E2/R422-INF-E2 Installation and User's Guide
1-2 Serverboard Features
At the heart of the NovaScale R422-E2/R422-INF-E2 lies two R422-E2/R422-INF-
E2 dual processor serverboards, which are based on Intel's 5520 chipset. Below
are the main features of the NovaScale R422-E2/R422-INF-E2 serverboard. Note
that the features on each board are doubled for the server.
Processors
Each NovaScale R422-E2/R422-INF-E2 serverboard supports two Intel
®
5500
series (LGA 1366) processors, each processor supporting two full-width Intel
QuickPath Interconnect (QPI) links with a total of up to 51.2 GT/s Data Transfer
Rate (6.4 GT/s per direction). Please refer to our web site for a complete listing of
supported processors (http://www.bull.com).
Chipset
Intel 5520 chipset, including the 5520 (North Bridge) and the ICH10R (South
Bridge).
Memory
The NovaScale R422-E2/R422-INF-E2 serverboard has twelve 240-pin DIMM
sockets that can support up to 48 GB of DDR3 registered ECC 1333/1066/800 MHz
memory (with maximum of 8 GB per DIMM module) (see Section 5.6 in Chapter 5
for DIMM Module Population Conguration).
Serial ATA
The South Bridge (IOH-36D/ICH10R) of the 5520 chipset includes a Serial ATA con-
troller for 3 Gb/s SATA drives. The hot-swappable SATA drives are connected to a
backplane that provides power, bus termination and conguration settings. RAID 0
and 1 are supported.
PCI Expansion Slots
Each NovaScale R422-E2/R422-INF-E2 serverboard has one PCI-Express 2.0 x16
slot, so two PCI-Express 2.0 x16 slots are provided in the server. In the NovaScale
R422-E2/R422-INF-E2 server conguration, riser cards have been pre-installed to
support two low-prole PCI-Express 2.0 x16 add-on cards.
