5-12mb backup speeds for Virtual Appliance on Tegile array

Post by foxj77 » Nov 15, 2016 1:59 pm

Hi there,

We are relally struggling with the performance of our backups onto a Tegile array and this is leading to our backup jobs overunning and massively impacting performance. Anyone else out there using Veeam and a Tegile array and managed to configure it to run ok?

We have a VM running as a proxy in our VMware solution and its running really slowly. The setup is a VM running the Veeam services and the backup jobs are attaching the drives to the proxy but taking a long time to run and complete. We are seeing a 8gb backup taking anywhere between 15-20mins of two identical windows core servers.

I've been looking at the setup to try and optimise the bacup but cannot seem to get the backup rate to any quicker than 6-11mb. I've been reading the documentation on the site and think we have everything setup as needed.

Veeam themselves have looked over the setup and confirmed that everything is running correctly and the bottleneck is being identified as the source.

On our arrary I'm looking over the performance graphs whilst the jobs are running we are seeing no step changes in the read/writes to the disks and only seeing a notable increase in latency on the disk and fibre channel graphs. This of course goes on to impact performance across all of our VMs.

I've followed the notes in this article - https://www.tegile.com/blog/tegile-and- ... s-forever/ with no huge success :-(

Anyone else got any tips on getting usable performance out of Veeam on a Tegile array?

Haven't you tried other transport modes (direct SAN, network) to check performance?

Are you doing Incremental or Reverse Incremental?

Do you have your production VMs you are backing up, a VM with Veeam installed, and the backup target storage all on the same Tegile array?

Can you move Veeam to a physical server and separate the utilization? Maybe that will free up the source bottleneck a little.

Are you suing Reverse incremental or incremental as someone says,

Reverse we get 10-20 mb/s
Incremental we get 400+ mb/s

I understand the overheads of reverse but it is a massive difference, for us anyway.

We have the same problem. New Tegile SAN installed about a month ago. Moved our Exchange, File Servers, etc to it and backup performance dropped dramatically. We were getting 100-200 MB/s when these servers were on our older IBM SAN. Now are getting under 10 MB/s on Exchange and 10-30 MB/s on our File Servers. These backups run at night there isn't a lot of I/O from clients

We use Virtual Applicance mode on our Virtual Veeam Proxies. We have tried Direct Access to the Tegile and the results are the same.

Our Replication Servers that use the same Virtual Proxies that sit on the old IBM san still cruise at over 100+ MB/s

What are we missing on the Tegile SAN?

Hi Casey, what are the bottleneck stats for the jobs?

Bottleneck is the Source.

Exchange job that ran last night sitting on Tegile:
Avg 7 mb/s
Source 97% > Proxy 11% > Network 4% > Target 4%

Rep File server sitting on IBM SAN:
Avg 127 mb/s
Source 99% > Proxy 26% > Network 5%> Target 0%

Veeam says it is the source on pretty much all of our jobs regardless of which SAN (IBM or Tegile) the VM resides on.

I'd recommend involving Tegile specialists, since it looks like the storage is not able to deliver data any faster.
