Here is my /etc/apt/sources.list file entries: deb http://ftp.us.debian.org/debian wheezy main contrib non-free deb-src http://ftp.us.debian.org/debian wheezy main contrib non-free # PVE packages provided by proxmox.com for non-subscription Proxmox VE 3.x deb...

Thank you Dietmar. That did the trick. Now onto the hard part of configuring the x540-t2's to do iscsi connectivity for our pve boxes. I appreciate your help.

I am running into problem install the Intel X540-T2 driver. I got a tar.gz file from the intel site for the driver for this card.When I unpack it I get ixgbevf-2.12.1 source directory and no .deb package . After I had to install build-essential to get the missing make utility (etc), I still get...

Hi All, Sorry if this is more of a straight Linux networking issue, but I am hoping to resolve this under Proxmox 2 so we can use it as our VM server. The setup is Proxmox 2 server whose storage will be iscsi SAN based (Enhance 3160TG - using 10gbe fiber) . We have been testing and coming to...

Hi Spririt - Not using a switch. Doing direct connect (peer to peer) using autocrossover feature of the cards. Thanks.

One more thing. Win2k8 loaded directly on same server that had Proxmox on it - no OS changes or ethernet tweeks to Win2K8 default installation - just made sure using latest Intel 10Gigabit ethernet driver. Using IOmeter, and their IOmeter config file, we got close to published Enhance-Tech...

Bad thing about the Enhance Technologies SAN is that it is a locked box - can't change any parameters. Found out from them that their maximum MTU they recognize is 3000. SO we just turned off Jumbo Frames altogether . Poor performance cannot be explained by just Jumbo Frame support. It seems...

Hi Udo- The VM is using the iscsi directly on an attached RAID 0 100GB LUN from the Enhance SAN. When I ran the dd tests from host (at proxmox shell prompt ) I get on slightly higher rates: 10GB file with sync'ing - rates ~ 70MB/s. iperf rates were disappointing as well . Was using Writethrough...

Results from iozone testing on CentOS VM under Proxmox 2.0-45: Proxmox kernel version: 2.6.32-10-pve; VM ( CentOS kernel info: 2.6.32) Memory on VM is 6 GB, using virtio to a 100 GB LUN (RAID 0 over 4 disks) from the SAN for OS and disk space (together) Note 1: Might want them to be separated...

Installed newest ixgbe 10 gigabit ethernet driver. Still getting low bandwidth. Used netstat and found packet loss and retransmissions. Here is some out put : # netstat -s | grep retrans 247239 segments retransmited 3063 times recovered from packet loss due to fast retransmit...

Thank you Udo for your suggestions. I checked the driver version with modprobe ixgbe and found that we are using the standard Intel 10 Gigabit PCI Express Net Driver version 3.7.17-NAPI. This is only one month out of date. I did not upgrade at this point yet. I do not have a 1GB NIC connection...
