• When handling hard drives, follow industry-standard practices. Internal storage media can be damaged when drives are shaken, dropped, or roughly placed on a work surface. When removing a drive, press the release button, and then pull the drive only slightly out of the enclosure. Then, to allow time for the internal disk to stop rotating, wait approximately 10 seconds before completely removing the drive from the enclosure. • If your environment includes multiple servers, HP recommends designating one of the servers as a management server, to centralize management tasks. It is on this server that you install management software such as the ACU, and it is from this server that you perform SAN management tasks. • When installing or updating HBA drivers, always use the drivers and installation scripts provided on the MSA Support Software CD and the MSA1500 website. The MSA will not operate as intended if you update your HBA driver manually or use drivers obtained from the HBA manufacturer. • When assigning system names and aliases, use only the following characters: • Uppercase alpha characters (A-Z) • Lowercase alpha characters (a-z) • Numeric characters (0-9) • Special characters and space) • If you are connecting the MSA to existing servers, you may need to re-install some of your management software after installing the MSA. • In dual-controller multipath configurations (both active/active and active/passive), you must install some management software (such as multipathing software, management/monitoring utilities, and array configuration software) on each server with access to the MSA. • When planning and configuring the LUNs: • In direct-connect environments or any environment using the ACU-CLI, a minimum of one storage LUN on the MSA must be configured and set to the appropriate host mode before connecting the MSA to the server. • When determining how many hard drives to include in an array and how many LUNs to create from that array, consider the I/O load of the data that will be stored on those LUNs, and, also consider that rebuild and expansion times increase with the number of drives. • Optimize performance and redundancy by striping the drives in the array across separate storage enclosures on different SCSI buses, especially in mirrored environments using RAID 1 or RAID 1+0. • In general, striping an array across many hard drives increases the total throughput on that array and delivers better I/O performance, but there is a performance trade-off when an array is divided into multiple LUNs. Too many LUNs on the same group of hard drives causes more drive seeking and a loss of throughput. 22 Installation procedures-All deployments

Installation procedures—All deployments

•

When handling hard drives, follow industry-standard practices. Internal storage media can be

damaged when drives are shaken, dropped, or roughly placed on a work surface. When

removing a drive, press the release button, and then pull the drive only slightly out of the

enclosure. Then, to allow time for the internal disk to stop rotating, wait approximately 10

seconds before completely removing the drive from the enclosure.

•

If your environment includes multiple servers, HP recommends designating one of the servers as

a management server, to centralize management tasks. It is on this server that you install

management software such as the ACU, and it is from this server that you perform SAN

management tasks.

•

When installing or updating HBA drivers, always use the drivers and installation scripts provided

on the MSA Support Software CD and the MSA1500 website. The MSA will not operate as

intended if you update your HBA driver manually or use drivers obtained from the HBA

manufacturer.

•

When assigning system names and aliases, use only the following characters:

•

Uppercase alpha characters (A-Z)

•

Lowercase alpha characters (a-z)

•

Numeric characters (0-9)

•

Special characters (! # + ( ) ’ ; , . and space)

•

If you are connecting the MSA to existing servers, you may need to re-install some of your

management software after installing the MSA.

•

In dual-controller multipath configurations (both active/active and active/passive), you must

install some management software (such as multipathing software, management/monitoring

utilities, and array configuration software) on each server with access to the MSA.

•

When planning and configuring the LUNs:

•

In direct-connect environments or any environment using the ACU-CLI, a minimum of one

storage LUN on the MSA must be configured and set to the appropriate host mode before

connecting the MSA to the server.

•

When determining how many hard drives to include in an array and how many LUNs to

create from that array, consider the I/O load of the data that will be stored on those LUNs,

and, also consider that rebuild and expansion times increase with the number of drives.

•

Optimize performance and redundancy by striping the drives in the array across separate

storage enclosures on different SCSI buses, especially in mirrored environments using RAID 1

or RAID 1+0.

•

In general, striping an array across many hard drives increases the total throughput on that

array and delivers better I/O performance, but there is a performance trade-off when an

array is divided into multiple LUNs. Too many LUNs on the same group of hard drives causes

more drive seeking and a loss of throughput.
