Dynamic Device Method

Using this method, the server allocates devices (up to the "start quantity" defined in the installation parameters) when a request is received. When no requests are pending, the devices can be used by other jobs or started tasks.

Based on the level of service required and the number of pending requests, the operator can increase (up to the "maximum quantity" defined in the installation parameters) or decrease the number of devices the server tries to use.

This method provides no guarantee that devices are available to the IOA Archive server when needed. If many requests are pending and not enough devices are available, response time for users degrades.

This method is recommended when the server is often idle, or when there is a shortage of 3490 drives.
