Introduction
The HP xw4400 Workstation offers flexible storage options in a compact chassis. There is support for
SATA 1.5Gb/s (sometimes called “SATA-1”) and SATA 3Gb/s (sometimes called “SATA-II”) drives,
integrated SATA RAID and optional Serial Attached SCSI (SAS) RAID.

Drive Bays. These
bays are convertible
to additional 1” HDD
Bays
(2) Tool-less 1.0”
3.5” Drive Bays
The xw4400 supports (2) tool-less internal 1” HDD slots and (3) 5.25” tool-less optical bays. Two of
the 5.25” bays can be converted to additional 1” internal HDD bays using the optional DY659A
bracket. When configured with 4 HDD bays, the xw4400 can support up to 3.0TB of SATA 3Gb/s
storage. The optional SAS controller supports up to 4 disks, allowing up to 1.2 TB of SAS 3Gb/s
storage.

The xw4400 supports many combinations of SATA and SAS drives for both factory integrated and
After Market Optional (AMO) storage. The supported choices are shown in the flowchart, starting
with the selection of SATA or SAS for the first drive. The xw4400 has an integrated SATA RAID
controller, but a SAS controller must be added before any SAS drives. HP supports the LSI SAS304
1E SAS Controller. The PCIe-based adapter supports up to 4 internal SAS drives. As indicated, it is
possible to start off with a SATA drive and add a SAS controller and up to 3 SAS drives.

RAID
The xw4400 has an integrated Intel ICH7R SATA RAID controller that supports RAID 0* (Striping, for
performance) and RAID 1* (Mirroring, for fault tolerance) and is capable of RAID 5 and 10. For
SAS, the SAS3041E controller provides support for RAID IS, IM, and IME. In all cases, disks in a
RAID array must be identical. Also note that using disk mirroring halves the amount of available
storage. Setting up a SATA RAID configuration on the xw4400 is the same as on the xw4300. More
details on the xw4300 SATA RAID configuration can be found in Setting up SATA RAID on the
xw4300.
Cabling
For Factory-integrated storage, all required cabling is provided. For AMO storage, a SATA cable kit
is provided with each drive ordered. SAS drive AMO kits include a SATA cable and a SATA to SAS
drive adapter.
Summary
The xw4400 provides a large amount of highly-configurable storage in a small chassis.
