Veeam and HP 3PAR StorServ 7400, direct san access

[Ratti3]

Hi,

We have just purchased a HP 3PAR StorServ 7400 SAN to replace an EVA 4100.
I'd like to know if Veeam supports this SAN for direct san access for backups?

Thanks

Hello!

If you are talking about direct SAN access transport mode that is used during backup and replication jobs to retrieve data from the source storage, than Veeam B&R is storage agnostic in this sense and you can configure direct access to any storage that allows it.

Veeam B&R also provides Veeam Explorer for SAN Snapshots functionality, which currently allows for granular VMware recovery from HP StoreVirtual VSA and LeftHand snapshots. HP 3PAR support is coming in Veeam B&R v7.

Thanks!

thanks that makes sense, good to know, looking forward to some blistering speeds during backup.

looking forward to some blistering speeds during backup.

Kindly keep us updated about the results you'll get. Thanks.

Btw, today we announced another disruptive innovation that will be available in Veeam B&R v7 - Backup from Storage Snapshots. Stay tuned for further info about this feature.

Got the results. System is the following:

Old System:
EVA 4100
15 NL Disks (500GB - 1TB) RAID5
27 FC Disks (146GB - 300GB) RAID5

Speeds were about 50 - 70 MB/s

New System:
3PAR 7400 (2 Configured Nodes)
48 FC 900GB 10K Disks RAID5 in 4 Cages

Speeds are now 200 -250 MB/s, this is showing as about 150-170 IOPS per disk, so near the max of 200 IOPS per disk.

Note the old EVA was allocated to the max, not all the data has been transferred to the 3PAR.
Did some IOMeter tests:

4K 80% Random reads

EVA - 170-400 IOPS 0.5-1MB/s <-- LOL
3PAR - 5000 IOPS 21MB/s (consistent at the moment)

Any questions about the 3PAR ask away

Hi.

Check these out in regard to SAN mode with 3PAR (I understand that you are already using it, but anyway FYI) :

Impressive numbers. Thanks for sharing!

[Ratti3]

I have now transferred 70% of the VMs accross.

I'm now getting about 600MB/s, this is 2 jobs running at the same time.

Note Veeam is using CBT for these backups, on Friday an Active Full will run, I will post the results for that.
The backup repository is a HP DL380e Gen 8, with 18 1TB 7.2K SFF, I get 50,000 IOPS on a 32K Seq IOMETER test, so Veeam still reports the 3PAR SAN as the bottleneck.

Thanks for sharing value information; highly-appreciated.

In addition, please, don't bother about the bottlenecks statistics, especially, when you get such a remarkable performance speed. The bottleneck stats just provide you with the information regarding amount of time that every backup component is busy, so the bottleneck will be always present (in every setup).

Thanks.

Do you have any performance stags on you're full active backup because we are migrating from netapp to a p7400 (2N) with 80 900 10 SAS disks and 20 3TB MDL SAS disks to a DL380p with 10+12 4TB disks

Hi, could you share how your job in Veeam is setup? How large is the datastore/volume that you are trying to backup? Are you backing up the data to a volume on 3APR or another EVA as a targer?

I am seing impressive speeds during full backups but incremental backups from 3PAR volumes are 1/4 of the speed.

Got the results. System is the following:

15 NL Disks (500GB - 1TB) RAID5

i get with veeam 7 in full backup 500MB/s , reverse incremental only between 25 and 80 MB/s but veea says it is the target

[Gostev]

Reversed incremental is 3x I/O on target comparing to full, so target is almost always a bottleneck for this backup mode.
