Target initial configuration Some effort is required to map all the activity at the target, but it is clear that, between 20:00 and 02:00, the target has a very heavy load because local backups, replication jobs from sites A and D and housekeeping associated with replication jobs from sites B and C are all running at the same time. Target improved configuration Consider improving the situation by imposing two housekeeping windows on the target device as shown below. By applying housekeeping windows we now can free up spare time on the target D2D (shown in dotted area on diagram), which could then be used either for future headroom for growth or to schedule tape offloads. 105

Target initial configuration
Some effort is required to map all the activity at the target, but it is clear that, between 20:00 and 02:00, the
target has a very heavy load because local backups, replication jobs from sites A and D and housekeeping
associated with replication jobs from sites B and C are all running at the same time.
Target improved configuration
Consider improving the situation by imposing two housekeeping windows on the target device as
shown below.
By applying housekeeping windows we now can free up spare time on the target D2D (shown in
dotted area on diagram), which could then be used either for future headroom for growth or to
schedule tape offloads.
