Gigabit Ethernet Transfers with XT3 Servers for Avid
DNXHD® and Apple ProRes 422
Preliminary note
The following observations focus on steady rates; the transfer
performances with small clips will be lower as they generate a lot of
starts and ends of sessions.

SIMULTANEOUS BACKUP AND RESTORE
The backup sessions reach higher bandwidth and pre-empt the bandwidth against
the restore sessions. On a ‘per session’ based, the system allocate between 3.75
and 6 times more bandwidth to backup session than to restore session.
