1) yes we're running active/active we're not using server_3 as a standy

2) yeah I'm a little uncertain about that too, on the visio diagrams I have of NS80G I do see 2 ports labeled as AUX0 and AUX1 but on the back of mine, I just see
BE0,BE1,FC0,FC1, are these ports different in technical terms? or is it just a labeling thing?

4) we will be backing up 4 separate 1TB Luns, and I have seen better performance by dedicating 1 drive to each LUN when backing up, each of the C4s have 2 drives

5) we're currently on 5.5 33-2

we will be using netbackup 6.5.3 as the NDMP client

appreciate the response and thanks for the suggestions man

Few things I like to check -

1) It seems you are running active/active data mover configuration for the 2 blade NS80G - is that correct? If Data mover 3 (server_3) is a standby data mover, you can not use it for Backup

2) On a data mover, FC0 & FC1 - which are typically called AUX1 and AUX1 are used for backup - so yes you are right on using these two ports.

3) Create seperate zone for the AUX ports - so yes you are in right track

4) I am not sure why you want to use two Tape units here for the same data mover. Rather, I 'll connect only one Tape unit and zone it to AUX0 (FC0) and AUX1 (FC1) - since they are on the same switch. In fact, you may consider connecting to only AUX0 - though it depends on how many drives you have on the Tape unit, how much data you want to backup.

5) Lastly - what NAS code you are running? Is it quite old code?

I am sure there will be more comments/suggestions from others.

2) Yes it is only a labeling - AUX 0 and AUX 1 are at times labeled as 0 Fiber and 1 Fiber

4) You may consider spreading over the backup job for different time. Anyway - I don't find any issue having two different TLU connected to same Data mover - but may be bit more than required.

In that case, it becomes just like a direct connection from Data mover AUX port to Tape Unit - as if there is no need to have a switch environment.

By the way, please ensure that the Tape Unit and the FC bridges are the EMC supported one as per the EMC Support Matrix. I know Netbackup 6.5 is supported with NAS code 5.5.

Thanks,

As always thank you for you valuable input Sandip

My absolute pleasure. Also, it will be so nice of you, if you can mark the relative replies as Correct (only one) and/or Helpful (upto 2).

Thanks again,
Sandip

re: the labeling - FC0 and FC1 vs AUX0 and AUX1. It would be quite helpful if the documentation team and the hw team updated in sync with each other.
I was looking for aux0 as well (from past experience) and from the pdf documentation.

thanks for the clarification Sandip.
