Introduction
The ProLiant Storage System is a cost-effective, high performance external
storage system for Compaq server products. The storage system provides up to
30.1 gigabytes of hard drive mass storage using hot-pluggable Fast-Wide
SCSI-2 and Fast-SCSI-2 hard drives. All operating systems will benefit from
the easy to service pluggable drive connection scheme.

Options
The following options are available for your ProLiant Storage System and may
be obtained from your local Compaq Reseller or Authorized Compaq Service
Provider.
Fast-Wide Duplexing Option Kit
Compaq Part Number 199614-001
Duplexing, or Controller Duplexing, refers to the technique of simultaneously
recording two sets of identical data (duplexing) using two completely separate
data paths. This provides total data protection through data mirroring (RAID
1). Because the entire data path is duplicated, a second SCSI controller, along
with its associated SCSI bus, is required. The two SCSI controllers need not be
in the same server.
A ProLiant Fast-Wide Duplexing Option Kit is available to divide the seven
drive bays on the single wide SCSI bus in the ProLiant Storage System into two
separate wide SCSI buses of four drives and three drives. This enables:
■ Separate controllers to implement advanced fault tolerant data protection
methods
■ Two servers to share the same storage system
The Duplexing Option may be installed by the user or by your Authorized
Compaq Service Provider. Installation instructions for the Duplexing Option
are included in the Fast-Wide Duplexing Option Kit and in Chapter 6 of this
guide.

Redundant Power Supply
Compaq Part Number 137889-001
An optional Redundant Power Supply is available to ensure that server access
to stored data will not be interrupted due to power supply failure. The
Redundant Power Supply is a dual power supply with both halves running
simultaneously and independently at approximately one-half power. Should
one half fail, the other automatically assumes the full load.
If a failure occurs in one half of the redundant supply, front bezel indicators
warn of the failure. The storage system continues operating at full capacity
while the user arranges for service at a convenient time.
Installation and replacement of the Redundant Power Supply option must be
performed by a Compaq Authorized Service Provider.

Chapter 2
Configuration Planning
The Compaq ProLiant Storage System can be used with a variety of SCSI
controllers, hard drives, and system software.
SCSI Controllers
The ProLiant Storage System can be used with any of the following controllers:
■ Compaq SMART SCSI Array Controller option board
■ Compaq 32-Bit Fast-Wide SCSI-2/E Controller option board
■ Compaq 32-Bit Fast-Wide SCSI-2/P Controller option board
■ Integrated 32-Bit Fast-Wide SCSI-2 Controller in Compaq ProLiant
1500 servers
■ Compaq 32-Bit Fast-SCSI-2 Controller option board
■ Integrated 32-Bit Fast-SCSI-2 Controller in Compaq ProSignia,
ProSignia 500, ProSignia 300, ProSignia VS, ProLiant 1000, 2000,
4000, and Systempro/XL servers.
■ Wide-Ultra SCSI Controller (see Wide-Ultra SCSI Support below)
■ SMART-2 Array Controller
All Compaq Fast-SCSI-2 controllers, including the SMART SCSI Array
Controller, are capable of data transfer rates of 10 megabytes per second. Fast-
Wide SCSI-2 controllers are capable of data transfer rates of 20 megabytes per
second.
Wide-Ultra SCSI Support
The ProLiant Storage System /F supports the use of Wide-Ultra SCSI drives
and controllers. However, even with all Wide-Ultra SCSI components (drives,
controllers, and drivers), data transfer will be limited to Fast-Wide SCSI-2 rates
(20 MB/s).

Hot-Pluggable Drives
The ProLiant Storage System /F supports these Compaq hot-pluggable drives:
■ 1.6-inch Fast-SCSI-2
■ 1.6-inch Fast-Wide SCSI-2
■ 1.6-inch Wide-Ultra SCSI (see Wide-Ultra SCSI Support later in
this chapter)
■ 1-inch Fast-SCSI-2
■ 1-inch Fast-Wide SCSI-2
■ 1-inch Wide-Ultra SCSI (see Wide-Ultra SCSI Support later in
this chapter)
ProLiant Storage System will accept both 1-inch and 1.6-inch standard height
drives. The drives may be of any storage capacity but must be mounted on
Compaq hot-pluggable drive trays.
Hot-Pluggability
The ProLiant Storage System supports hot-pluggable drives. Under certain
conditions these drives can be removed or installed without turning off the
power to the storage system or the server. This feature eliminates interference
with the operation of the server while replacing drives in some configurations.
In planning your configuration it is important to understand that the hot-
pluggability feature must also be supported by the operating system and
controller. See Table 2-1.
Hot-pluggable drives in fault-tolerant configurations can be used to replace
failed drives without powering down your system. The data on the failed drive
will be automatically restored on the replacement drive.

Compaq ProLiant Storage System User Guide
Writer: Don Shimel Project: Configuration Planning Comments:
File Name:E-CH2.DOC Last Saved On:3/12/97 12:50 PM
IMPORTANT: When using NetWare software drive mirroring, the drive
that contains both the DOS partition used to boot the server and the
NetWare server files should not be hot-plugged. Although the system can
be booted from a drive in the ProLiant Storage System, the DOS partition is
not mirrored by NetWare. Therefore, if a hot-pluggable drive containing
the DOS partition fails, the DOS partition will not be reconstructed from the
mirrored drive. Refer to the SCSI.RDM file on the NetWare Programs From
Compaq diskette for more information. This diskette can be generated
from the Compaq Software Support CD or Compaq SmartStart CD provided
with the ProLiant Storage System.
Hot-pluggable drives can also be used as a means to provide high-capacity
direct access removable media. Systems supporting the "removable media"
must be initialized with all drives in place so that they are recognized and
configured into the list of available devices.
IMPORTANT: Drives used in a fault-tolerant configuration cannot be
used as removable media data storage. When a drive is removed, the
operating system flags it as failed and will automatically try to rebuild the
lost data from the other configured drives when the failed drive is replaced.
Hot-pluggability features are dependent on operating system or SCSI controller
support. Refer to README files or Release Notes on Compaq-supplied
operating systems for information about hot-pluggability.
CAUTION: To prevent loss of data, drives must be removed and replaced
only under certain conditions, basically when both the
Drive Access
and
On-Line
indicators are OFF. Refer to "Removing and Replacing Hot-
Pluggable Drives" in Chapter 4 of this guide for information about these
conditions

2-6 Configuration Planning
Writer: Don Shimel Project: Configuration Planning Comments:
File Name:E-CH2.DOC Last Saved On:3/12/97 12:50 PM
SCSI IDs
All devices on a SCSI bus must have unique identification numbers.
The drives used with the ProLiant Storage System are automatically assigned
SCSI ID numbers depending on the drive bay in which they are installed.
CAUTION: Server lockups could occur if a drive is installed in a drive
bay set with a SCSI ID that is already used by another device in the server
if both devices are on the same SCSI bus.
For example: assume that the SCSI controller in the server is connected to
a tape drive (SCSI ID of 1) and a CD-ROM drive (SCSI ID of 6) installed in
the server. If the external port of the same SCSI controller (same SCSI bus)
is connected to a ProLiant Storage System, drives must be installed in the
storage system drive bays with IDs from 2 through 5 to avoid using IDs 1
and 6, the same IDs that have been assigned to the internal SCSI devices
IMPORTANT: All SCSI hard drives on the same SCSI bus must be either
internal (within the server) or in an external storage system, but not both.
A configuration with both internal and external SCSI hard drives requires
more than one single-channel SCSI controller. A multi-channel controller,
such as the Compaq SMART SCSI Array Controller, supports both internal
and external SCSI hard drives on separate SCSI buses.
