Time Guidelines and Migration Performance Values

Your best estimate of time and space requirements are generated by running EDMT against a
copy of your production database, on hardware (see Appendix D) similar to your production
environment, in a lab environment. For customers that do not have that ability the following
subsections provide information gathered while performance testing in the labs (see Appendix
E) at Cisco Systems, Inc.

Typical Database Migration Performance Values

The following table provides high level guidelines for the upgrade times for Loggers and HDSs
based on the hardware (as defined in the 

 (http://www.cisco.com/

en/US/products/sw/custcosw/ps1001/products_user_guide_list.html) and the results observed
during internal upgrade testing (see Appendix E). Actual times vary based on the parameters
previously discussed.

Backup, Network Copy, and Restore – Technology Refresh Only

Copy speed is dependent upon the speed of the network and the speed of the disk sub-system.
The faster the network the faster the copy completes.

• The values in the Database Used Size in the table above are based on the amount of disk

space used by the Source database, not the size of the disk it resides on.

• The Backup/Copy/Restore Times in the table above assume the network meets the minimum

requirements of the 

 (http://www.cisco.com/en/US/products/

sw/custcosw/ps1001/products_user_guide_list.html).

• For Technology Refresh upgrades, have the fastest network possible (gigabit through one

network switch) between the source and the destination machines. Use of a crossover cable
is not recommended because it lacks buffer memory and can cause data loss.
