Mirroring Recover, you might configure the application to use 512 MB and

Storage Mirroring Recover to use 256 MB, leaving 256 MB for the operating

system and other applications on the system. Many server applications

default to using all available system memory, so it is important to check and

configure applications appropriately, particularly on high-capacity servers.

Any changes to the memory usage will not take effect until the Storage

Mirroring service has been restarted on the server.

● Maximum disk space for queue—This is the maximum amount of disk

space, in MB, in the specified Folder that can be used for Storage Mirroring

Recover disk queuing, or you can select Unlimited which will allow the

queue usage to automatically expand whenever the available disk space

expands. When the disk space limit is reached, Storage Mirroring Recover

will automatically begin the auto-disconnect process. By default, Storage

Mirroring Recover will use an unlimited amount of disk space. Setting this

value to zero (0) disables disk queuing.

● Minimum Free Space—This is the minimum amount of disk space in the

specified Folder that must be available at all times. By default, 50 MB of disk

space will always remain free. The Minimum Free Space should be less

than the amount of physical disk space minus Maximum disk space for

queue.

Note:

The Maximum disk space for queue and Minimum Free Space

settings work in conjunction with each other. For example, assume

your queues are stored on a 10 GB disk with the Maximum disk

space for queue set to 10 GB and the Minimum Free Space set to

500 MB. If another program uses 5 GB, Storage Mirroring Recover

will only be able to use 4.5 GB so that 500 MB remains free.

● Specify the Alert at following queue usage percentage. This is the

percentage of the disk queue that must be in use to trigger an alert message

in the Linux system log. By default, the alert will be generated when the

queue reaches 50%.
