Site Prep Team and Tasks
The objective of a site prep is to prepare your site for the successful and
timely installation of the HP XP12000 disk array. Proper site preparation is
vital for the reliability of the disk array.
Site prep involves a careful balance of equipment design criteria, site
environmental variables, your business needs, and your budget constraints.
In addition to this guide, other site prep resources may be available to you.
The HP service organization is committed to making sure you receive the
maximum benefits of your disk array. HP representatives will guide and
assist you throughout the site prep process.

12 HP StorageWorks XP12000 Disk Array Site Preparation Guide
The site prep team
The site prep team plans, schedules, and completes all tasks necessary to
prepare your site for successful disk array installation.
The site prep team consists of HP representatives and you, the customer.
HP representatives
The HP team includes various HP representatives who have the training,
knowledge, experience, tools, and parts required to install and maintain XP
disk arrays. This team:
• Helps you to determine and implement the site requirements for your
specific site and array configuration
• Coordinates all HP resources to ensure successful delivery and
installation of the disk array
Your HP SR is your primary point of contact with HP during the site
preparation process.
Customer
As part of the site prep team, your responsibilities include planning and
preparing a suitable environment for the disk array, and scheduling
equipment delivery and installation. However, HP representatives are
available to help you throughout the site prep process. Your internal site
team may include personnel specializing in your site computer room, such
as your storage administrator and your site electrician.

Site Prep Team and Tasks 13
Site prep tasks
Contact your HP SR for guidance and assistance at any time during the site
prep process.
1. If you have not printed a copy of this guide, HP recommends that you
print at least Chapter 2 and the “Site prep checklist” (page 13). Working
from printed copies will make it easier to use the tools provided and will
produce hard copy documents that you can keep for your records.
2. Carefully review Chapter 2 to understand the site requirements for the
disk array.
3. Use the information, instructions, and tools in Chapter 2 to determine
site requirements for the specific disk array components you ordered.
4. On the site prep checklist, answer each item “Yes” or “No” as it relates
to your site. The checklist includes references to the pages in this guide
where you can find more information on each item.
5. Checklist items that require a “Yes” answer are marked with asterisks
(*). If you answer “No” for any of these items, your site does not meet
site requirements for the disk array. Using the information in Chapter 2,
correct the site environment so that you can answer “Yes” for each of
these items.
6. When your site meets all site requirements, contact your HP SR to
coordinate delivery of the disk array equipment.
7. If you choose to unpack the equipment cartons without HP supervision,
follow the instructions in Chapter 3.
8. Contact your HP SR to schedule the disk array installation and
configuration.
Site prep checklist
Checklist items that require a “Yes” answer are marked with asterisks (*).
The customer summary information is included for the benefit of HP
representatives, who will help you complete the checklist.

18 HP StorageWorks XP12000 Disk Array Site Preparation Guide
Disk array physical specifications
Use the information in this section to determine the total dimensions and
weight for your specific array configuration. You will need these values to
complete other processes in this chapter.
The disk array includes one disk controller frame (DKC), which contains
the controller electronics for the disk array and some hard disk drives, and
zero to four disk array frames (DKUs), which contain additional hard disk
drives. Figure 1 shows the disk array with the maximum of four DKUs.
Figure 1. Disk array minimum/maximum configuration
Supported configurations are:
• One DKC (minimum configuration)
• One DKC and one DKU (R1)
• One DKC and two DKUs (R1 and R2 or R1 and L1)
• One DKC and three DKUs (R1, R2, and L1 or R1, L1, and L2)
• One DKC and four DKUs (maximum configuration)

Site Requirements 19
Dimensions
Use the packaged values when determining delivery space requirements
(page 60), and unpackaged values during space planning (page 32).
Weights
Use the approximate packaged weights when determining delivery space
requirements (page 60), and unpackaged weights to calculate the total
weight of your configuration (page 22).
Table 3 (page 20) provides the approximate weights for:
• Minimum configuration — base cabinet without additional product
components
• Maximum configuration — base cabinet fully populated with product
components

The main factor that increases total weight is the number of disk drives.
The actual weight is the base cabinet weight plus the weight of all
additional components installed.
Table 4 provides the approximate weights of additional disk array
components when integrated into a DKC or DKU cabinet.

1 For shipments from the USA to locations outside the USA and Canada, add 59 kg (130 lb)
for an international shipping crate.
2 Within the USA and Canada, most shipments use a special carrier process in which frames
are shipped without pallets, ramps, and cartons. In these cases, the packaged weight is the
unpackaged weight plus 23 kg (50 lb).
3 For upgrade DKU packaging (includes a ramp), add 29 kg (65 lb).
