Hi Martin,

I can not update to the new kernel. Aptitude update/safe-upgrade do not show me any pending updates. I tried also to install the latest proxmox-ve-2.6.35.
Not sure what the problem is. Can I force the update ?

Kind regards.

Current pveversion:
Code:
BigOne:~# pveversion -v

strange. download the missing packages manually and install them manually:

Code:
wget http://download.proxmox.com/debian/dists/lenny/pve/binary-amd64/proxmox-ve-2.6.35_1.8-11_all.deb http://download.proxmox.com/debian/dists/lenny/pve/binary-amd64/proxmox-ve-2.6.35_1.8-11_all.deb http://download.proxmox.com/debian/dists/lenny/pve/binary-amd64/vzdump_1.2-12_all.deb

and install:
Code:
dpkg - i ......
 
Does the 2.6.35 kernel have support for PCI_DEVICE_ID_ARECA_1880 ? (Areca ARC-1880-ix cards). From what I see we'd need to wait until .37 for main debian kernels.

Could anyone suggest a good 12 or 16-port raid card known to work well?
 
Great thanks!... I have been looking for release notes on these kernels ... are there any? What improvements can we expect?

NO, I cant see that symbol in the sources.
 
The Adaptec unified raid-controllers really rock, terrible fast and absolutely reliable.
We use eg: Adaptec RAID 51645

I had a test server with an Areca 1261 / ARC1280ML that worked well. (I don't remember which version it was - "lspci" and the silkscreen on the PCB didn't agree with each other, my notes are a little vague) That particular machine was running the stock PVE 1.7 / OpenVZ kernel, quite a bit older. The 1261 is 16-ports, the 1280 is 24.

Our new servers are running Dell PERC H700 cards, which are reworked LSI MegaSAS 9260 controllers. They're only 8 ports, but I'd imagine the larger cards in the series would work fine. (Kernel 2.6.32-4-pve, megaraid_sas module)
 
Cool, thanks for the feedback. We were able to build a custom kernel and get it working... but now another question:

Anyone try the (PMC) Adaptec 6805/6405 series? We got a few new servers with this card based on Adaptec saying the card used the same drivers, but this is false. Got it working in a debian install using the drivers from adaptec, but having trouble in proxmox.

Will this driver (Adaptec 6 series) be included in a near release of proxmox? (it flies with the BBU under debian - faster and cheaper than the 5405Z/5805z, and included cable as well!)
 
till now we don´t get the new series of Adaptec in our test labs - still looking for a sponsor. are they really faster than the 5er series? they are much cheaper and not proposed for high performance on the Adaptec website.

what trouble do you get on Proxmox VE with these cards?
 
Why do you say they are not proposed for high performance at adaptec? I saw they still say: "Series 5 still delivers high performance in all server-related workloads with a high number of I/O operations like OLTP and file servers, the Series 6 offers enhanced bandwidth with its 6Gb/s SAS 2.0 and PCIe Gen2 interfaces"...But I find that interesting, as with 6.0Gb/s 10k drives in a raid 1E we were getting about 4k fsyncs/sec (using the proxmox pveperf tool in debian). I can send the output when I am back at the office.

I will talk to my boss on Monday, but I am sure we can sponsor a card and the zmcp (bbu). Can I have him email you?
 
I am referring to this page:
http://www.adaptec.com/en-us/products/controllers/hardware/?channel=tab1

the first row shows 'performance' controllers, the second 'value' controllers. and the value controllers are also cheaper, using another raid chip - so I assume they do not perform such good as the 5er series but as I wrote we do not benchmark the 6 series so I do not know it really.

And yes, would be great if you want to sponsor a card for our test lab here. just contact martin@...
 
Hello !

Do you have any plan to include 2.6.38 kernel to pvetest repo ?
I have deeply tested pure kvm performance on 2.6.32, 2.6.35 and 2.6.38, and the cpu usage for the same task is just better :)

  • nic:e1000 kernel:2.6.32 --- WinCPU:90% ProxCPU:100%
  • nic:e1000 kernel:2.6.35 --- WinCPU:30% ProxCPU:80%
  • nic:e1000 kernel:2.6.38 --- WinCPU:25% ProxCPU:75%
 
currently there is no plan to include 2.6.38.

regarding cpu usage and network: use virtio, should be less cpu intensive.

Thanks for the response, I will wait a few year and ask again ;)

About virtio, It always crash with intensive network usage, and I tested it with 1.6 and 2.0 dll, over those 3 kernels branch. (2.6.32 / .35 / .38)
Crash = no more network packet.
 
if you see a case where the network crashes please open a new thread and describe a way to reproduce the issue.
