Source Bottleneck [Case ID: 01106362]

Post by sebastian » Nov 17, 2015 7:17 pm

Helly everyone,

we are new to Veeam B&R and have a big problem. At every Backup we get a Source Bottleneck with 99%.

Image

Environment:
14xESXi Hosts:
DELL R720 and R710 - ESXi 5.5

Physical Backup Server:
1xDELL R710 (2xE5630, 48GB RAM, X520 NIC) – Server 2008 R2 SP1 with all updates – B&R 8 2084

iSCSI SAN:
2xDELL Equallogc PS6510E

Backup Repository:
NAS Deluxe Storage

-Backup Server, SAN and Backup Repository are connected via 10GbE
-direct SAN Access is selected
-the SAN Network is mentioned as the privileged network
-in the host file the ESXi server is mentioned and when I ping the name of the ESXi server it is resolved correctly over the SAN network
-the LUNs are integrated with MS iSCSI-Initator
-backups go over the 10GbE network as I can see in the task manager

I set up a Backup Proxy (2vCPUs, 4GB RAM, connected do SAN network) for testing on another ESXi as the machine I want to backup – no speed improvement.

I ´ve got a remote session with a veeam engineer last week and he said, that the problem is at VMware. What do you think? Is there something I didn´t see or is something wrong configured?

If you need more informations, let me knew it.

Thanks

118MB/s is not bad, why do you see this as "big problem"? Please note, that there will always be the bottleneck somewhere, in every setup, since one of the components still will make others to wait.

Thanks for the quick response.

Well, faster is always better ;-)

I expected a higher speed, because the EQL isn´t old and not really bad at all. Also we have a lot of VMs to backup and i think when we make full backups at weekend this could be a problem.
Furthermore the engineer said that the speed should be higher. Also the speed doesn´t improve at night which should in my opinion, because there is less load on the SAN as at the daytime.

You might want to try more VMs in the job to get some parallel task.
