HP ProLiant DL380 G4 Storage Server configuration

With up to six internal drives and fault-tolerant options for fans and power supplies, an HP ProLiant
DL380 server acts as a high-capacity Exchange server. Other HP ProLiant servers can support 900
to 2,000 Exchange mailboxes.
When configuring the server and storage, ensure that you have:
Sufficient RAM (1 GB) on the server.
Enough disks for the Exchange database volume, especially if you use RAID 5 RAIDsets or ADG.
A larger number of disks improves database volume performance.
The Exchange server internal RAID storage holds the transaction logs. HP recommends storing the
transaction logs on a RAID array accelerated with a write-back cache, with battery backup. The
transaction logs can be stored on an iSCSI NAS RAID array.
For the sample configuration, the server includes a Smart Array 5i RAID controller option kit since the
write cache for this controller can be set at 100%, increasing performance.
RAID 1+0 is preferred for the database volume on the storage server. In the sample iSCSI NAS storage
configuration:
The DL380 G4 Storage Server uses a Smart Array 6402 and Smart Array 6404 controller to access
the disks for its RAID array.
56 disks are available for RAID configurations. These disks sit in four rack-mountable HP
nl
StorageWorks Modular Smart Array 30 (MSA30) disk enclosures with 14 drives each.
A 40-disk RAID 1+0 configuration consists of an array of 10 disks in each of the four enclosures.
The Exchange server accesses its database on the iSCSI NAS RAID 1+0 volume.
