Control backup traffic to the media servers
On disk pool storage units, you can use the settings to control the backup traffic to the media servers. Effectively, this setting directs higher loads to specific media servers when you use multiple storage units for the same disk pool. A higher number of concurrent jobs means that the disk can be busier than if the number is lower.
For example, two storage units use the same set of media servers. One of the storage units (STU-GOLD) has a higher setting than the other (STU-SILVER). More client backups occur for the storage unit with the higher setting.
