4.3. Quality of Service (QoS)

This section outlines the QoS selection for individual disks and the usage instructions to create

QoS specific RAIDs.

The provided flash GUI allows you to manage the pool of online disk with a QoS (Quality of

Service) setting. This setting allows you to easily “mark” drives with a specific QoS setting in

accordance to the drive specs.

For instance, one would want to create different RAIDs on different disk quality or specs in

order to match the production requirement of this RAID.

A RAID destined to archiving files, for instance, would require bigger but cost effective drives

since the RAID will not be used for intensive IOs but rather for large storage. For that reason it

might be a good idea to only use large SATA drives for this RAID.

On the other hand, RAID serving very fast and data demanding applications might require less

storage space, but sturdier and faster drives, such as more expensive but more reliable SAS

drives.

For that reason, the QoS setting was introduced, letting the user marking his drives according to

their final use, and to be able to create a specific QoS RAID using the matching User defined

QoS drives.

4.3.1. Disk Management

• The QoS setting must be defined for each drive separately.

• The QoS setting can be changed at any time by the User, except if the drive is already

part of an active RAID.

• There are currently 3 QoS level settings available on the system:

o Mission Critical (default level).

o Business

o Archive

In order to select the QoS for a specific drive, you need to navigate to the following section

within the GUI: Click on the Administration tab ÆClick on the Disks sidebar button.

Within this disk management view, you will then need to locate the drive for which the QoS

setting needs to be changed by clicking on the “disk edit” button as shown below:

1 2 ... 36 37 38 39 40 41 42 43 44 45 46 ... 71 72
