1 Cabling Preparation for HP 3PAR StoreServ 7000/7450

The following instructions list important precautions and information about cabling installation options for the HP 3PAR StoreServ Storage system.

Following Precautions

Follow these general precautions to avoid injury, data loss, and damage before and during installation or while servicing the HP 3PAR StoreServ Storage system:

• Avoid using improper tools

• Prepare an Electrostatic Discharge-safe (ESD) work surface by placing an antistatic mat on

the floor, or table, near the storage system. Attach the ground lead of the mat to an unpainted surface of the rack

• Always use a wrist-grounding strap, provided with the storage system. Attach the grounding

strap clip directly to an unpainted surface of the rack

• Avoid contact between electronic components and clothing which can carry an electrostatic

charge

• Ensure all cables are properly labeled and easily identifiable prior to removing a component

• Observe local occupational safety requirements and guidelines for handling heavy equipment

• Always load the heaviest item first, and start from the bottom when loading the rack. Loading

from the bottom makes the rack bottom-heavy and helps prevent the rack from becoming unstable

• Do not attempt to move a fully-loaded equipment rack. Remove all equipment from the rack

before moving the rack

• Use at least two people to safely move the rack from the pallet

Identifying and Labeling the Components

This section of the chapter applies to all configurations in this guide. The guide provides instructional guidance for cabling the HP 3PAR StoreServ 7000/7450 according to a specific configuration. All HP 3PAR StoreServ Storage systems contain either the HP 3PAR 7200 (2 nodes) or 7400/7450 (with 2 or 4 nodes), M6720 large drive enclosure(s), and M6710 small drive enclosure(s).

The M6720 large drive enclosures supports 3.5-inch disk drives and the smaller M6710 drive enclosure supports 2.5-inch disk drives.

The cabling configurations are identifiable by the specific number of nodes connecting to a combination of small or large disk drive enclosures. The cabling configuration examples below uses the following identification:

• 2 Node 10 Drive Enclosure (1S) refers to a configuration using two nodes connecting to one

small (2.5-inch) disk drive enclosure

• 2 Node 10 Drive Enclosures (6S+4L) refers to a configuration using two nodes connecting to

a combination of six small (2.5-inch) and four large (3.5-inch) drive enclosures

Types of Components

Use the red and green color coding to assist with the cabling. Only connect to components sharing the same color.

Figure 1 Identifying Components and SAS Ports

Identifying and Labeling the Components 5

Labeling the Enclosures

Before connecting the cables:

• Labels (A, B, C, and D) are provided to help identify the enclosures in the storage system.

Apply the labels to each enclosure in a visible location and avoid covering other labels

• Apply label A to the controller enclosure with nodes 0 and 1. Alternate the labeling (A/B) on

each enclosure below the controller enclosure

If applicable, a system using four nodes, apply label C to the controller enclosure with nodes 2 and 3. Alternate the labeling (C/D) on each enclosure above the controller enclosure.

The illustration below describes a typical configuration using two nodes and a combination of large and small drive enclosures.

NOTE: The illustrative depiction may not reflect the configuration setup of your system but the

labeling pattern is similar.

2 Node 1 Drive Enclosures (1L)

Before you begin cabling the storage system, carefully read or print the following section, including figures 1 and 2, “Identifying and Labeling the Components” (page 4).

Attach DP-1 Chains to Enclosures

This system does not require any connections to node port DP-1.

Attach DP-2 Chains to Enclosures

Red routing

1. Connect Node 0 (DP-2) to the I/O 0 (DP-1) on the B drive enclosure closest to the controller.

2. Connect all A drive enclosures from (DP-2) to (DP-1) working away from the controller.

Green routing

1. Connect Node 1 (DP-2) to I/O 1 on the B drive enclosure farthest from the controller.

2. Connect all B drive enclosures from (DP-2) to (DP-1) working toward the controller.

NOTE: The two adjacent enclosures are not directly connected.
