1.2 Serverboard Features
Figure 1-1 NovaScale R422 Motherboard (X7DBT/X7DBT-INF)
At the heart of the NovaScale R422/R422-INF server lies two (twin) NovaScale R422
X7DBT or two NovaScale X7DBT-INF dual processor server boards, which are based on
Intel's 5000P chipset. Below are the main features of the NovaScale R422 X7DBT/X7DBT-
INF motherboard. Note that the features on each board are doubled for the server.
Processors
Each NovaScale R422 X7DBT/X7DBT-INF motherboard supports dual Intel® 5300/5100
Series processors.
Memory
The NovaScale R422 X7DBT/X7DBT-INF motherboard has eight 240-pin DIMM sockets
that can support up to 32 GB of ECC FBD (Fully Buffered DIMM) DDR2-667/533 SDRAM.
Memory can be installed in both interleaved (dual-channel) and non-interleaved (single-
channel) confi gurations. All memory modules used to populate the system should be the
same size, type and speed.
Serial ATA
The South Bridge (ESB2) of the 5000P chipset includes a Serial ATA controller for 3 Gb/s
SATA drives. The hot-swappable SATA drives are connected to a backplane that provides
power, bus termination and confi guration settings. RAID 0 and 1 are supported.
PCI Expansion Slots
Each NovaScale R422 X7DBT/X7DBT-INF motherboard has one PCI-Express x8 slot, so
two PCI-Express x8 slots are provided in the server. In the NovaScale R422/R422-INF
server confi guration, riser cards have been pre-installed to support two low-profi le PCI-
Express x8 add-on cards.
Ethernet Ports
Two Intel® 82563EB network controllers are integrated into the 5000P chipset on each
