Operational Behavior

The ETC is calculated every 30 seconds by dividing the total blocks outstanding (to be copied,
flushed, compared or scrubbed) by the job’s current performance (MBps).

NOTE:

Because the performance of a job depends on numerous external factors, ETC values

may dynamically change during the job’s execution.

Offline ETC job

If an offline job is Running, ETC is the total outstanding blocks that are yet be copied from
source to destination, divided by the job’s current performance (MBps):

Outstanding blocks / current performance MBps = ETC

If an offline job is running with the Verify option, ETC is the total remaining blocks that are
yet to be copied plus the size or the source LUN, divided by the job’s current performance
(MBps):

Outstanding blocks + source LUN size / current performance MBps = ETC

If an offline job is in Verify state, ETC is the total outstanding blocks that are yet to be verified
from source to destination, divided by the job’s current performance (MBps):

Outstanding blocks / current performance MBps = ETC

If an offline scrubbing job is running, ETC is the number of passes left times the size of the
source LUN plus the number of blocks left for the current pass, divided by the job’s current
performance (MBps):

(Number of passes left x size of source LUN) + number of blocks left for the current pass /
current performance MBps = ETC
