    How to properly tune 10Gbe card for best rates to iscsi SAN

    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...

    IOzone CentOS 6 VM to SAN Performance Results over 10GbE

    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...

    IOzone CentOS 6 VM to SAN Performance Results over 10GbE

    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...

    IOzone CentOS 6 VM to SAN Performance Results over 10GbE

    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...

    Large File write test to iscsi san causes Proxmox to hang

    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 This is only one month out of date.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...
