System notes
The AW2000h is a 2U twin server system. With four mainboards
incorporated into a single chassis acting as four separate nodes, there
are several points you should keep in mind.
The server has an integrated dual-port Gigabit Ethernet which
supports Intel I/O Acceleration Technology (IOAT), iSCSI boot, Virtual
Machine Device Queues (VMDq) and PCI-SIG SR-IOV implementation.
Each node can be installed with one or two CPUs, different memory
capacities, different number and capacities of HDDs.
Nodes
Each mainboard acts as a separate node in the system. As independent
nodes, each may be powered off and on without affecting the others.
In addition, each node is a hot-pluggable unit that may be removed
from the rear of the chassis. The nodes are connected to the server
backplane by means of an adapter card.
System power
A single power supply provides the power for two serverboards. Each
serverboard however, can be shut down independently of the other
using the power button on its own control panel. An additional power
supply module is needed for a fully configured system with four
serverboards.
SATA backplane, drives and RAID
As a system, the AW2000h supports up to twelve SATA drives. There
are three hard drives per node in the system. A single SATA backplane
works to apply system-based control for power and fan speed
functions, yet at the same time logically connects a set of three SATA
drives to each serverboard. Consequently, RAID setup is limited to a
three-drive scheme (RAID cannot be spread across all twelve drives).
