Adding TL895 Libraries to the Compaq Enterprise Backup Storage System
Sizing Calculations
Before you can begin the sizing process, you must have a thorough understanding of the
network, the type of data to be backed up, and the back-up window parameters. The easiest and
most precise way to size an Enterprise Backup System is to use the Compaq StorageWorks
Enterprise Backup Solution sizer software, which may be obtained from the Internet at
http://www.compaq.com/products/storageworks/ebs/ebstoolsbackupsizing.html.
If you do not have access to the software, the whitepaper entitled Sizing the Compaq
StorageWorks Enterprise Backup Solution (Part Number
ECG551/0399
) found
at:
http://www.compaq.com/support/techpubs/whitepapers/
will walk you through the manual
sizing process. The basic steps are:
1.
Calculate the Base Rate
2.
Adjust the Base Rate
3.
Calculate Number of DLT Drives Needed
4.
Determine the Retention Parameters
5.
Determine Number of Tapes Required
6.
Determine Number of Libraries Needed
