Introduction to the Enterprise Virtual Array
The Enterprise Virtual Array is a product that consists of one or more storage systems.
A storage system consists of a pair of HSV controllers and the physical disk drives
they manage. Each storage system is formally called an Enterprise Storage System.
For the purposes of this manual, this name is frequently shorted to just "the storage
system."
This chapter gives an overview of what an Enterprise Storage System is both
functionally and physically.
After you become familiar with the parts of the storage system, the flowchart in
Chapter 2 will lead you through installation.
Functional Layout of the Storage System
The current trend is to view data storage as analogous to a utility, such as electricity or
water. Like a utility, storage is centrally managed, always there (except in catastrophic
instances), and can be expanded and reconfigured to fit changing needs.
The Enterprise Virtual Array implements this strategy. Centralized management
software controls the storage system and lets an administrator configure the storage
required by various host computers. The management software creates pseudo disks,
called virtual disks, and presents them to a host (or to two or more hosts). The host
sees the virtual disk just as it sees any ordinary disk drive.
For example, say you need for your work computer a 300-GB disk drive with the
highest possible reliability. An authorized administrator accesses the management
software through a browser, creates the required virtual disk on the storage system,
and presents it to your computer. All you see is that your computer suddenly is
attached to a highly reliable 300GB disk drive.
What you don't see is virtualization--how the management software works with the
controller software to create the virtual disk drive by distributing data among the
physical disks of the array.

Virtualization
The Enterprise Storage Systems use a new virtualization technology that moves
beyond traditional RAID. In this new virtualization technology, the physical disks are
organized into disk groups. A disk group is a pool of raw capacity from which the
administrator can allocate the capacity and data protection characteristics of a virtual
12 Enterprise Virtual Array Initial Setup User Guide
Introduction to the Enterprise Virtual Array
disk. The virtual disk will be presented as a LUN to a host for application use. The
virtual disks that the controllers present to the host computers are created using the
capacity of all the drives in the disk group, as shown in Figure 12.
Figure 12: Traditional RAID versus Enterprise virtualization techniques
This new type of virtualization allows data to be distributed more evenly among the
physical disks, thus avoiding hot spindles which occur when data is distributed
unevenly. Each virtual disk's data is distributed evenly across as many physical disk
drives (spindles) as the virtual disk's data protection policy will allow. The leveling
process is dynamic and looks for opportunities to improve utilization, such as a
change in the number of disks in the disk group.
The HSV Element Manager
An Enterprise Storage System is monitored and managed centrally through the HSV
Element Manager, a user-friendly graphical user interface (GUI). The element
manager is installed on a Compaq SANworksTM Management Appliance that is
attached to the fabric on which the hosts and the storage system reside.
The element manager's client is a standard web browser. The element manager uses
the paradigm of folders to organize the various storage system components.
Enterprise Virtual Array Initial Setup User Guide 13
Introduction to the Enterprise Virtual Array
There is a help system associated with the element manager. The help guides you
through specific actions and also presents conceptual information about the storage
system.
Physical Layout of the Storage System
Physically the storage system consists of a pair of HSV controllers and their array of
physical disk drives. The basic physical components are shown in Figure 13. The
physical disk drives plug into disk drive enclosures. The controller pair is cabled to the
disk drive enclosures. A backplane in the disk drive enclosures distributes commands
and data to the drives.

Introduction to the Enterprise Virtual Array
Figure 14 shows a block diagram of how the whole storage system works:
The HSV controller pair connects to two Fibre Channel fabrics, to which the hosts
also connect.
The HSV Element Manager is the software that controls the storage system. It
resides on the Management Appliance. The Management Appliance connects into
the fabric.
The controller pair connects to the physical disk array through Fibre Channel
arbitrated loops. There are two separate loop pairs: loop pair 1 and loop pair 2.
Each loop pair consists of 2 loops, each of which runs independently, but which
can take over for the other loop in case of failure. The actual cabling of each loop
is shown in Appendix A.

Obtaining a License Key
A license key is necessary to unlock the Virtual Controller Software (VCS) that runs
on both controllers in a storage system. One license covers both controllers in a
storage system.
Obtaining a License key requires several documents. See Chapter 3 for instructions on
locating these documents.
Compaq StorageWorks Enterprise Virtual Array World Wide Name (WWN) Label.
License Key Retrieval Instruction Sheet, which includes the License Authorization
ID.
If you purchased the snapshot license, you will also need the snapshot License Key
Retrieval Instruction Sheet, which includes the License Authorization ID.
VCS License Types and WWN
There are two types of VCS licenses:
Basic
Snapshot
These licenses are sold as part of a software kit. Snapshot is sold based upon the
snapshot capacity the customer requires.
There is one WWN per controller pair on a storage system.
IMPORTANT: Both the license and the WWN are required to create an initialized storage
system.
Basic License
The basic license provides the right to use VCS to create and operate an Enterprise
Storage System whose Fibre Channel identity is the World Wide Name that was
generated by manufacturing and attached to the hardware. A single VCS software kit
provides the basic license which covers both controllers in the storage system.
Enterprise Virtual Array Initial Setup User Guide 41
Obtaining a License Key
The license is bound to the World Wide Name (WWN). The WWN is a characteristic
of the entire storage system as an entity. This relationship is shown in Figure 41. The
license and the WWN do not belong to any specific component of the storage system.
Individual components can be removed and replaced--even the controllers--but the
storage system remains and retains its World Wide Name identity.
Both the license and the WWN are required to create an initialized storage system.
License World Wide Name
Storage System
CXO7708A
Figure 41: Relationship of the license and the WWN to the storage system
The WWN, which is generated by manufacturing and attached to the hardware,
belongs to the storage system. It is entered into the operator control panel (OCP) of
one of the controllers (described in Chapter 6), but it does not belong to the
controllers. The controllers simply keep a record of the WWN until the storage system
is initialized. At the time of initialization the WWN is tied to the storage system.
The basic license must be tied to the WWN. This is done through the License
Fulfillment Process described in the next section. You will receive an Authorization
ID on a License Key Retrieval Instruction Sheet. You will provide the Authorization
ID and the WWN to the license fulfillment website. The license fulfillment website
42 Enterprise Virtual Array Initial Setup User Guide
Obtaining a License Key
will then generate and send back a license key. This license key ties the WWN to the
license. When this license key is entered into the HSV Element Manager, it unlocks
VCS on both controllers, and you can begin using your storage system.
Snapshot License
The snapshot license gives you the right and ability to use the value-added snapshot
function. A snapshot is a fast virtual copy of a virtual disk at an instant in time. You
must have the VCS basic functionality before enabling this value-added feature.
The Snapshot license follows the same licensing scheme as described for the Basic
License.
License Fulfillment Process
The license fulfillment process can be completed manually through email or fax, or by
visiting the Compaq website.
If you have more than one license or more than one storage system, you can obtain up
to 10 license keys at the same time. Each license key is locked to the WWN of one
storage system, so keep records that show the association of license keys with WWNs.
Basic Licensing Process
Follow the instructions on the License Key Retrieval Instruction Sheet to obtain a
license key at the license fulfillment website. If you do not have web access, the
License Key Retrieval Instruction Sheet describes how to obtain a license key
manually through e-mail or fax.
IMPORTANT: The manual process could take up to 48 hours so obtaining your license key
should be one of your first priorities.
The license fulfillment website will prompt you to enter the storage system's World
Wide Name (WWN). This is the number that is on the sheet called Compaq
StorageWorks Enterprise Virtual Array World Wide Name (WWN) Label. This number
may also be on labels on both sides of the controllers (see Figure 42).
Enterprise Virtual Array Initial Setup User Guide 43
Obtaining a License Key
CAUTION: You must enter the WWN exactly as it is on the label before you submit the
licensing information. The WWN entry is case-sensitive and the hyphens must be
entered. Once the WWN is entered into the licensing database, the license key is
irrevocably locked to that WWN.
Do not enter the checksum that appears on the label into the website. Doing so will
invalidate the license key.
CXO7601A
Figure 42: Location of the World Wide Name label
When you obtain the license key, copy it or print it. You will need to enter the license
key into the HSV Element Manager, as described in Chapter 7. The license key is
made up of alphanumeric characters and may have as many as 4 lines of text. It is very
important that the license key be entered exactly.
Snapshot Licensing Process
If you bought the snapshot feature, follow the same process as above using the
snapshot License Key Retrieval Instruction Sheet.
44 Enterprise Virtual Array Initial Setup User Guide
Obtaining a License Key
Licensing Additional Storage Systems
If you have more than one license or more than one storage system, you can obtain up
to 10 license keys at the same time. Each license key is locked to the WWN of one
storage system, so keep records that show the association of license keys with WWNs.

Installing the Storage System Hardware
Moving a Rack
After completing the procedures listed in "Prerequisites" on page 51, you can move
the rack to the installation area.
WARNING: The physical size and weight of the rack requires a minimum of two
people to move it. If one person tries to move the rack, there is a potential for
injury.
To ensure stability of the rack, always push on the lower half of the rack. Be
especially careful when moving the rack over any bump (for example: door sills,
ramp edges, carpet edges, or elevator openings). When the rack is moved over a
bump, there is a potential for it to tip over.
Moving the rack requires a clear, uncarpeted pathway that is at least 80 mm (30 in)
wide for the 60.3 cm (23.7 in) wide, 42U rack. A vertical clearance of 203.2 cm
(80 in) should ensure sufficient clearance for the 200 cm (78.7 in) high, 42U rack.
CAUTION: Ensure that no vertical or horizontal restrictions exist that would prevent
rack movement without damaging the rack.
Make sure that all four leveler feet are in the fully raised position. This process will
ensure that the casters support the rack weight and the feet do no impede movement.
If the feet are not fully raised, complete the following procedure:
1. Raise one foot by turning the leveler feet hex nut counterclockwise until the
weight of the rack is fully on the casters. (Reference Figure 54 in performing this
step.)
2. Repeat step 1 for the other feet.

Applying Power
CAUTION: Before applying power to the system be sure that the temperature has
stabilized and is in the range +10C to +35C (+50F to +95F). If the system
temperature is outside of this range, an error condition will exist when you apply power.
Applying power to the rack involves the following steps:
1. Place the circuit breakers on both power distribution units (PDUs) to the Off
position.
The PDUs are located in the back of the rack. See Figure 59 for location of the
circuit breakers and Figure 510 for a close-up view of the circuit breakers.

2. Place the controller enclosure power switches to the Off position.
3. Connect the PDU power cable to the wall receptacle.
At this time, you can apply power to the rack enclosures.
4. Place both the PDU circuit breakers to the On position.
At this time, the drive enclosure power supplies will start operating. The audible
alarm will sound, but should turn off as soon as both controllers are fully powered
up.
5. Verify that the power supply and blower status LEDs (green) are On.
The middle drive status LED should be On; the other two drive state LEDs should
be Off. The I/O module status LED (middle) should be On.
The drives will start to spin up, during which time the top drive status LED will
blink. When the two top drive status LEDs are On and the bottom drive status
LEDs are Off, the drive has spun up. Wait until the drives have spun up before
turning on the controllers.
IMPORTANT: If you see any error indications, refer to the Drive Enclosure User Guide and the
EMU User Guide for possible causes and corrective actions.
6. When all the drives are spun up, place the power switches of both controllers to
the On position.
The LCD on the controller enclosure operator control panels (OCPs) should show
"HSV Startup." When one of the controller's OCP displays the message "Enter
Node WWN" the controllers are running their software and are operational.
When both controllers are powered up, the audible alarm should turn off

Attaching the Controllers to the Fabric
The controller pair attaches to its hosts through a Fibre Channel fabric. A fabric
consists of a switch or a group of interconnected switches. The convention is to
represent a fabric as a cloud.
For redundancy, the controllers should be cross-connected to two fabrics; that way, if
one fabric becomes nonoperational the hosts still can get to the data through the other
fabric.
NOTE: Some operating systems have specific requirements for how switches are configured.
Consult the Installation and Reference Guide for the operating systems of your hosts. The
specific operating system constraints always take precedence over this generic description.
