Hello!
Customer used to run VMware backup using Netbackup, via NBD. They moved to Commvault and SAN transport mode.
Happens that, even with few data readers (6), underlying storage (SAS+SSD pool on a DELL Purity) where the Datastores resides is suffering a lot. Overall latency goes so high that the production environment goes down.
We are using HSX and SAN is 16Gb.
Does anyone has any experience with situations like this? Any clue? Is HSX via SAN too much for their storage?
Regards,
Pedro
Well I would say that the storage unit is not able to cope with additional load when running backups. Solution can be quite simple, change the transport mode from auto/san to nbd.

Hi! Yes… that is what I'm thinking… unfortunately the storage is not being able to deliver the required load by the SAN transport mode backup. Have you ever seen this (SAN mode trashes the environment and with NBD works fine)?

IMO SAN transport is preferred all the way around compared to NBD when you have the connectivity to do it. Simply limit the number of streams or parallel VM backups and you’ll find the sweet spot without killing the array. Been doing SAN transport for years, even with NetBackup.
