Appliance 5220 NDMP backup extremely slow
I have problem with NDMP backup. I'm using a 5220 with 2.5 software on it to backup a EMC configured as a V-Block using NDMP.
Speed I see is average of 5MB/s??? I have ha a few backup to run about 50MB/s but this is til very slow for a NDMP backup.
NBU 220.127.116.11 installed on master server. Appliance have a 10GB network adapter, EMC also have a 10GB nic, not a dedicated backup nic. Both connectet to the same core switch.
I've tryed using buffer files, and I can see new buffer setting beeing used when backup runs. But there are no changes to the backup speed.
Looking at the EMC when backups are run, there are almost not I/O on disk, controllers.. So bottle neck does not seem to be here.
Strange this is that I cannot see much traffic on the 5220 nic either..
Policy selection setup:
Set filesystem =/something/
Set Hist = yes
Set direct = yes
Set level = 0
So the the big question is how can I get speeds up and running??
Any help much appreciated
