Managing Tape Library Directly Connected to Unified VNX 3500
I want to have an end solution where client backups are stored on disk for a period and also copied over to tape. At the moment the solution I have is working but performance is poor.
In my current solution I have a Tape Library unit directly connected to Netbackup Media server. I have EMC Unified VNX sliced into 3 file systems. Using the VNX data mover the VNX file systems are mounted via NFS share onto the media server.
I am using Disk Staging to initially store backups to disk as stage 1. Then for stage 2 relocation of images to tape the backups are sent back over the network to the media server.
So I am looking to improve this situation as the relocation of images to the tape library takes a significant amount of time.
I would like to move the tape library to connect directly to the VNX. I know that the tape library can be controlled by the media server over NDMP when directly connected to VNX.
However I am curious to know if I can use disk staging in this scenario. Otherwise would using NDMP direct copy be an option?
Any opinions would be greatly appreciated.
