System Requirements for Virtual Appliances

To ensure that JSA works correctly, you must use virtual appliances that meet the minimum requirements.

Your virtual appliance must have at least 256 GB of storage available. Before you install your virtual appliance, use the following formula to determine your storage needs:

(Number of Days) x (Seconds in a day) x (Events per second rate) x (Average size of a log event x 1.5 JSA normalized event overhead) x 1.05 / (1000 x 1000 x 1000) + 40 GB

The following table describes the minimum memory requirements for virtual appliances.
