    yes... bottleneck is between theMedia server  and the DD..

    network is not good enough..

    the IP that you used to connect to DD is 10 gig network or 1 gig network...?

    Ipefr test is purly related to network test and no involment of Netbackup... so 

    you need to improve the network speed first before expecting the good speed in backup.

    work with network team to improve it.

     

     

    and yes.. vcenter 5.1 is fully supported with 7.5.0.5

    see the release note for 7.5.0.5

Hi Nagalla,

1) Please correct me if I am wrong, but didn't support for vm 5.1 start with 7.5.0.4? Is that correct? I am running 7.5.0.4 on Master and Media servers now.

2) I'm not sure why the job details dont mention the transport type. I ran the test job again, checked the bpbkar file, and I see no mention of the the transport type in there either. Is there something else specific I should be looking for inside the bpbkar log?

3) For my vm policies, I use the query method. BUT, for my test policy, I only have one test client, so I just added it in manually. I did go in and change the resource limit for datastore to 1, applied, and ran a manual backup of a policy that uses VM query. The results were about the same, at about 25MB/s.

I installed iperf, having never used it before, and I believe the results here are telling. Take a look.

C:\>iperf -c 10.20x.xxx.xxx -t 60 -i 10

This looks horribly slow to me.
