We currently have a single DPM server (2012R2 RU5) with 76TB of disk space connected to a tape library. As we are getting close to the 80TB limit we want to deploy another DPM server and have questions around it.

1) Can we move the local DPM DB to a shared SQL server and when we deploy the 2nd DPM server it will use the same DB?

2) Can we share our tape library between the two DPM servers?  We have a Dell TL4000 fiber channel dual drive system. 

- we perform disk backups on the weekend and we want to setup where both DPM servers have access to and can write to tape.  Possibly each DPM servers controls a single a single  drive but the DPM database needs to be aware of which DPM server the backup occurs from or can restore to.

Other issues I'm not thinking of?

Thanks

HI,

No need to move the DPMDB.  If you want multiple DPM servers to share a single tape library you can set up tape library sharing using this TechNet article.

I would also recommend TechNet article shared by Mike Jacquet.

Pre-requisites have been nicely explained in the blog post

Some of the trouble shooting steps which might be required are explained nicely in this article
