Plan to use Data Domain

[tasmacher]

We plan to use two Data Domain 670 or 860 in our TSM environment. Currently we use 2 IBM tape library. We backup Lotus Notes data and file services (Windows), SAP (DB2) and VMWare. Approx. 1000 nodes and 200 TB of data. So far we have nothing negative about the Data Domain systems. Are there things to note special or disadvantages which have the systems? We want to use the Data Domain at TSM 6.2.

Have you reviewed the DataDomain best practices for TSM guide?
Here is one and I am sure there is a newer version somewhere.

Utilizing the DD box as your primary disk allows longer retention on disk.
This is a good solution.
Good luck

We have Data Domain with TSM Server 6.2.3.0 and its running fine.

But in Library Manager we still using TSM Device Drive 6.2.2.0, when we upgraded the device drive to 6.2.3.0 got a lot of anr9999d, Data Domain recommended us to downgrade de device driver.
