Note: The MSA1000 must be installed in the sequence listed here and in the HP StorageWorks MSA1000 Installation Guide.

There are specific dependencies; if you deviate from this sequence, you may have to uninstall and reinstall your MSA1000,

beginning at step 1.

Two views of the MSA1000 are shown, with the key components identified.

5 Prepare your switches and hubs

In an existing SAN, your switches and hubs are already set up and configured,

but if you are deploying your MSA1000 into a new SAN, you need to install and

configure your Fibre interconnect devices at this time.

Installation Guide section: Step 4: Installing the HBA in your Servers

4 Install the HBA in your servers

Because the MSA1000 can be deployed into a variety of operating system

environments and configurations (including single-path and multi-path),

specific HBA are required for the different deployments. Obtain the correct HBA

for your environment and install the HBA into each server that will access the

MSA1000.

Note: Be sure to follow the procedure as detailed in the HP StorageWorks MSA1000

Installation Guide.

At this point in the installation process, you have prepared your servers and

Fibre interconnect devices for the MSA1000 and have connected your

MSA1000 to your SAN. With your SAN ready to go and the MSA1000 installed

and ready to go, you can now power up your MSA1000.

Note: Be sure to follow the procedure as detailed in the HP StorageWorks MSA1000

Installation Guide.

3 Prepare your servers

Depending on your plans, you will connect your MSA1000 to either a new or an

existing server. In both scenarios, it is important that your server is operating

properly before adding any MSA1000-specific components to it.

If more than one server will be accessing the MSA1000, HP recommends

designating one of the servers as a management server. It is on this server that

you will load management software (such as the ACU) and from this server that

you will perform your SAN management tasks.

With the MSA1000 and any additional storage enclosures installed in the rack,

you can now connect the SCSI, Fibre, and power cables.

Note: Multi-path configurations have exacting cable requirements.

At this point in the process of installing your MSA1000, you have prepared your

SAN for the MSA1000 and are ready to physically install your MSA1000.

After you install the MSA1000 and any additional storage enclosures in the

rack, you can install the hard drives into the units.

After the servers and interconnect devices are set up and the MSA1000 is

physically installed, connected and powered up, you can configure the

MSA1000 for your operating system environment.

These configuration steps vary for each operating system.

Note: Be sure to follow the procedure as detailed in the HP StorageWorks MSA1000

Installation Guide.

MSA1000 Installation and Configuration Best Practices

● Complete the Planning Worksheet on the opposite side of this document to

help you gather all of the items required for installing your MSA1000.

● Go to the MSA1000 website at http://www.hp.com/go/msa1000 to confirm

your plans and review current information about your MSA1000.

● When planning your LUNs, customize the RAID type and striping method to

the type of data that will be stored on the array.

For example, for non-critical data, you may want to use RAID 0, which

provides no fault tolerance, but provides rapid storage of large amounts of

data. For critical data, use RAID 1 (RAID 1+0), RAID 5, or RAID ADG,

choosing the RAID type the offers the desired combination of fault-tolerance,

I/O performance, and capacity utilization.

Note: Depending on the number of drives that you include in an array, the ACU

automatically assumes a default RAID type of ADG, which maximizes fault tolerance and

capacity utilization, but at a significant cost of I/O performance. For comparable fault

tolerance but higher performance, consider using RAID 1+0.

● When planning your LUNs, set the drive rebuild priority of your LUNs to

“high” to minimize exposure during a drive failure.

● When planning your LUNs, to optimize performance and redundancy in a

mirrored environment (RAID 1 or RAID 1+0), stripe the drives in the array

across the separate buses within the MSA1000 and any attached enclosures.

For example, because drive bays 1-7 in the MSA1000 are located on bus 1 and

bays 8-14 are located on bus 2, when creating a mirrored array with 6 drives,

include the drives in bays 1, 2, 3, and 8, 9, 10.

● In a SAN with multiple-servers, HP recommends designating one of the servers

as a management server, to centralize your management tasks.

It is on this server that you will install management software such as the ACU,

and it is from this server that you will perform your SAN management tasks.

● Use the HP StorageWorks MSA1000 Installation Guide to actually install and

configure your MSA1000.

Details are available in the installation guide that are not provided in this

Overview poster.

● Install your MSA1000 in the sequence listed in the installation guide.

Several installation and configuration steps include dependencies and if you

deviate from the listed sequence, you may have to un-install and then

re-install your MSA1000, beginning at step 1.

● Before installing your MSA1000, consider redundancies of power, storage, and

data paths.

To provide redundant power, be sure to plug the two power supplies on the

MSA1000 into separate Uninterruptable Power Supplies (UPS) on separate power

sources. If you only have 1 UPS, maintain separate power paths by plugging one

MSA1000 power supply to the UPS on one power source and plug the other

MSA1000 power supply to a separate power source.

To provide redundant storage, configure your LUNs using fault-tolerant RAID

levels and striping methods.

To provide redundant data paths, you must include two isolated fibre channel

fabrics and the associated hardware and software components in the

configuration. (For example, you must include two MSA1000 controllers, two

interconnect devices, and two HBAs in each server. Environments using Secure

Path software must install the software on each server.)

● When installing or updating the HBA drivers, always use the drivers and the

installation scripts provided on the MSA1000 Support Software CD or the

MSA1000 website.

Your MSA1000 will not operate as intended if you update your HBA driver

manually or use drivers obtained from the HBA manufacturer.

● After installing your MSA1000, remember to set your host mode to identify your

operating system to the MSA1000.

● If you need to install Secure Path software, be sure to follow every server reboot

prompt that is presented.

Failure to acknowledge a server reboot prompt may result in your path redun-

dancy not functioning properly. Be sure to reboot your server after the server

portion of the install and again after the client portion of the install.

1 Review your configuration plan

Before you install your MSA1000, it is important that you first thoroughly

research, study, and establish a configuration and installation plan for your

specific environment.

HP suggests that you go to the MSA1000 website for configuration

specifications and late-breaking information and complete the Configuration

Planning Worksheet on the reverse side of this poster.

As part of the planning process, now is the time to determine how you need to

configure the MSA1000 storage.

If your plans include adding any of the available option kits for the MSA1000,

install them now. It is easier to install these options before you install your

MSA1000 in the rack.

Some of the MSA1000 option kits include a redundant controller, additional

controller cache, redundant Fibre Channel I/O Module, embedded MSA SAN

Switch 2/8, and an embedded MSA Hub 2/3.

Note: Do not install any hard drives into the MSA1000 until after the MSA1000 installed

in the rack.
