Best Practices

2.3.1

Avoiding Points of Failure

 

To achieve maximum uptime when connecting a RAID subsystem into a storage environment,

 

it is imperative that points-of-failure are avoided. The best way to avoid them is through the

 

use of redundant components. As stated above, the cooling modules and PSU modules on the

 

subsystem are fully redundant. Using dual-redundant data paths will further minimize the pos-

 

sibility of system downtime.

2.3.2

Dual-Redundant Data Paths

 

When connecting the RAID subsystem to a server, dual-redundant data paths are recom-

 

mended. If one (1) data path fails, a second data path can be used to transmit data. Dual-

 

redundant data paths are supported by both the host and drive channels.

2.3.3

ID Mapping

 

Host ID mapping is flexible, in the sense that the same array can be associated with different

 

host ID/LUNs, allowing the host clustering configurations. Drives on different channels can

 

then be grouped into an array, and the array has its unique volume size, stripe size, and opti-

 

mization mode. Arrays of different RAID levels can be striped together into logical volumes,

 

making management of huge volume size an easier task.

Enclosure Chassis

2.4.1

Chassis Overview

i

The RAID storage subsystem chassis is an enhanced 3U metal chassis divided into front and rear sections, which are respectively accessed through front (see Figure 2.4) and rear (see Figure 2.6) panels. Pre-drilled mounting holes in the sides of the 3U RAID subsystem enclosure allow you to attach separately purchased slide rails so that you can install the enclosure into a rack or cabinet.

NOTICE!

Components accessed through the front panel are referred to as “Front Panel Components” and components accessed through the rear panel are referred to as “Rear Panel Compo- nents.”
