See if you can add this up. To start, we have about 200 Sun servers and
about 1200 NT servers. About 100 Sun servers and about 100 NT servers
are on the SAN and share the following EMC and Hitachi subsystems:

7 EMC 8830 frames with about 13 TB raid 10 useable, each
1 Hitachi 9980V frame with about 45 TB raid 5 useable

There are a whole lot of direct attached SCSI disk arrays and internal
disks in each of the 1200 NT servers. I can't even start as to how much
storage these servers account for. These all get backed up.

We use STK 9840A and 9840B drives. These drives can do about 20GB per
tape at about 20 to 40 mb per second.

500 tapes??? Well, I think I've mistaken or I kicked out an old number.
We probably use twice that. Most of the SAN disk is used for Oracle and
SAS databases. Oh yea, we also have about 200 TB of mainframe but IBM
manages that. So, do some math and figure out how many tapes we use on
a full backup. You can save me some time.


So you work for Boeing, right? One of the largest Powderhorn sites I know
of...
