Up to two instant access sessions can be created per node.
Remote backup and retrieve sessions and instant access sessions are mutually exclusive - when an instant access session is active, remote backup and retrieve sessions cannot run, and when remote backup and retrieve sessions are active, instant access sessions cannot run.
When NDU or network reconfiguration is in progress, remote backup, retrieve, and instant access sessions cannot run.
An instant access session can be created for a volume group that consists of up to four volumes.
For optimal system performance, it is recommended that up to 125 volumes be backed up to PowerProtect DD per appliance.
