We are evaluating Veeam 9.5 Backup and Recovery to backup all our virtual environment, simply the infrastructure: 2 EXSi 6.0u3 hosts, Vcenter 6.0 and Equalogic SAN PS6210. Using BCM57810 10Gb Nic, Netgear XS70T 10Gb switch.
Using the 10Gb network, I am trying to achieve a kind of a high backup speed in Veeam B+R. all the recommendation around suggesting going to the direct SAN access will get the best performance in terms of backup speed.
Thanks for the guide under [FAQ] Frequently Asked Questions https://forums.veeam.com/vmware-vsphere-f24/vmware-frequently-asked-questions-t9329.html#p39948
and to many urls like the justins IT blog http://www.jpaul.me/2010/08/the-missing-manual-part-1-veeam-b-r-direct-san-backups/
I configured a physical windows 2012 r2 server with 2 Nics (10Gb for Backup , second 1Gb for production), iSCSI initiator, access to the Equalogic SAN, "diskpart, automount disable", connect to a LUN ... I can see the disk at the windows management disk, run the backup and getting max speed of 200MB/s
. followed this link https://forums.veeam.com/veeam-backup-replication-f2/improving-direct-from-san-backup-speed-with-iscsi-san-t4093.html
"netsh, interface, tcp, set global autotuninglevel=disable" no change
, some recommendation under this link http://datacore.custhelp.com/app/answers/detail/a_id/1626/~/sansymphony---iscsi-best-practices
... no success neither. Therefore I have a 10Gb network, but just getting a 2Gb speed
Another test I mad is creating a VM Veeam B+R, getting 500MB/s
. then created another VM Veeam on the other ESXi horst to use another Nic and resources and run 2 backup in parallel to the same target... I get 800MB/s
at the target. this test is just to make sure there is no bottleneck at the source, destination, switch ...
So I think I am missing something in the physical SAN direct access method to get at least 800MB/s
much appreciated you efforts.
