1 Review and confirm your plans

Overview

Before installing the EVA, HP recommends that you:

•Develop an installation and configuration plan for your environment.

•Review all videos and documentation.

•Determine if the EVA will be fabric-attached (connected to Fibre Channel switch) or

direct-attached (connected to Fibre Channel adapter in server). The EVA4400 is factory

configured for fabric-attached. To change to direct-attached mode, see “Connecting to the

management module” (page 25).

NOTE: Models of the EVA4400 with an embedded switch (also known as the HSV300-S

controller) are configured in fabric-attach mode and must remain fabric-attached.

Prerequisites

Prerequisites for using this product include:

•A Fibre Channel switch installed in your environment

•An equipment cabinet suitable for 2U sized enclosures

•A management server running Windows for HP P6000 Command View software (server-based

management)

•A management module running HP P6000 Command View software (array-based management)

•A CD-ROM drive attached to either the management server or the server attached to the

management module

Plan your storage configuration

Proper planning of the system storage and its subsequent performance is critical to a successful

deployment of the EVA. Improper planning or implementation can result in wasted storage space,

degraded performance, or inability to expand the system to meet growing storage needs. Planning

considerations include:

•System and performance expectations

•Striping methods

•RAID levels

•Hard drive sizes and types

•Spare drives

•Array sizing (capacity)

NOTE: For the minimum supported configuration, and other configuration information, see the

QuickSpecs document at: http://www.hp.com/go/eva4400

Overview 5

System and performance expectations

To help determine the best way to configure your storage, rank the following three storage

characteristics in order of importance:

•Fault tolerance (high availability)

•I/O performance

•Storage efficiency

With your priorities established, you can determine which striping method and RAID level to use.

As highlighted in the following section, some configuration methods offer greater fault tolerance,

while other configuration methods offer better I/O performance or storage efficiency.

RAID levels

Vraid is the HP term for the implementation of RAID (Redundant Array of Independent Disks) storage.

Vraid is also referred to as redundancy in HP management software. Virtual disks with HP Vraid

use three key RAID methods: data striping, data mirroring, and parity error checking. Unlike

traditional RAID, all HP Vraid levels distribute data across all available physical disks.

Data striping improves speed by performing virtual disk I/O with an entire group of physical disks

at the same time. Mirroring provides data redundancy by storing data and a copy of the data.

Parity also provides data redundancy by storing data and the calculated parity for each stripe of

data. If a subset of the data on a physical disk becomes corrupt or the entire physical disk fails,

the data can be automatically recovered from redundancy so that data loss does not occur.

The EVA has four Vraid types: Vraid0, Vraid1, Vraid5, and Vraid6. Each Vraid type provides

unique I/O speed and has a different level of data redundancy, which directly effects the amount

of physical space used. Once a virtual disk is created, the Vraid type or level cannot be changed.

See Table 1 (page 6) for a comparison of the different RAID levels.

HP P6000 Command View implementation

HP P6000 Command View can be implemented in two ways:

•Server-based management—HP P6000 Command View is installed on a management server

connected to the EVA, providing management of multiple HP EVA storage systems. All

components of the software suite (HP P6000 Command View, HP Command View EVAPerf,

HP Storage System Scripting Utility, SMI-S EVA) are installed. Server-based management is

applicable to all EVA models.

•Array-based management—Beginning with HP Command View EVA 8.1, the EVA4400 is

shipped with HP P6000 Command View pre-installed on the management module within the

controller enclosure. Only one component of the software suite (HP P6000 Command View)

is installed. Array-based management is applicable to the EVA4400 only.

2 Prepare your site

Overview

Preparing your site means providing:

•Physical rack space for the equipment

•AC power for the EVA

•Proper ventilation and temperature conditions

•LAN or Fibre Channel cables to attach the EVA hardware to your network.

To ensure continuous, safe, and reliable operation of your equipment, place your system in an

approved environment.

Consider using the HP Enterprise Configurator (eCO) to help plan and configure racks and

rack-mountable devices. The eCO is available on the HP website:

http://h30099.www3.hp.com/configurator

Click Configure under Disk products.

Provide adequate structural support for the floor

Calculate the total weight of your equipment and verify that your site can support the weight.

Provide adequate clearance space and ventilation

Be sure to provide adequate clearance around the front and back of the racks. Provide at least

25 inches (63.5 cm) in the front of the rack to allow the doors to open fully and provide at least

30 inches (76.2 cm) in the rear of the rack to allow for servicing and airflow.

If there are unused spaces in your rack, attach blanking panels across those empty spaces to force

the airflow through the components instead of through the open spaces.

8 Prepare your site

Provide adequate and redundant sources of power

Make sure that you have two high-line power feeds installed near your computer. These two power

sources usually come from the same external power grid, but occasionally may originate from

different grids or even entirely different sources.

For protection against a power-source failure, obtain and include two uninterruptible power supplies

in your installation.

For power consumption specifications, see the QuickSpecs document at:

http://www.hp.com/go/eva4400

Remove product from packaging

1. Remove product from boxes.

2. Verify that contents match your expectations and site requirements.

•EVA4400 controller enclosure should contain:

One 2U controller enclosure with two HSV300 or HSV300–S controller modules,

two power supply modules, two fan modules, and two battery modules installed.

◦

◦Rack mounting hardware

◦Two 2.0 meter FC copper cables

◦Two power cords

◦Installation documentation

◦XCS controller software recovery CD

•Each FC disk shelf should contain:

◦One 2U M6412 disk enclosure, two power supply modules, two fan modules, and

two battery modules.

◦Rack mounting hardware kit

◦Two 0.41 meter FC copper cables

◦Two power cords

3. Inspect for damage.

If damage is present, contact your local HP representative.

3 Install components

Overview

Component installation includes:

•Rail kits

•Controller and disk enclosures

•Disk drives

NOTE: If you have ordered the factory integrated product, skip this chapter and go to “Turn on

power” (page 20).

Rack installation best practices

In addition to industry-standard recommendations, consider the following:

•Locate the heaviest items, such as uninterruptable power supplies (UPS) and additional disk

enclosures near the bottom of the rack.

•To make cabling easy, install the disk enclosures below the controller enclosure.

•Install similar components next to each other in the rack. Because enclosures, switches, and

servers are of differing depths, if you have more than one of a device, mount those devices

adjacent to one another to accommodate working behind the rack.

WARNING! To reduce the risk of personal injury or damage to the equipment, be sure that:

•At least two people lift the storage system during removal or installation, if the weight, exceeds

22.7 kg (50 lb). If the system is being loaded into the rack above chest level, a third person

MUST assist with aligning the system with the rails while the other two people support the

weight of the system.

•The leveling jacks on the rack are extended to the floor.

•The full weight of the rack rests on the leveling jacks.

•The stabilizing feet are attached to the rack if it is a single-rack installation.

•The racks are coupled together in multiple-rack installations.

•Only one component in a rack is extended at a time. A rack may become unstable if more

than one component is extended.

•To prevent damage and to ease insertion of the device into the rack, support the weight of

the device and keep it level when sliding it into the rack.

Review Figure 1 (page 11) before installing the EVA components in the rack.
