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).
