    Hi Raudi,

    Did you try Sanmelody out ?? I was wondering how the ISCSI side compared. Ive been looking at it using FC cards with ESX server, and so far it works without issues. So from my point it is the open-e side that has issues with ESX server and FC cards certainly not my hardware.

    No, last week i was not in the country. Vacation, came back today.

    With the iSCSI Enterprise i cant't use FC, i was thinking about to use a iSCSI HBA but my ESX host is a dual Xeon quad core with 1,86 GHz, there must be enough CPU for the software iSCSI...

    A customer has a EqalLogic and he has 93 MB/s during sequential read and write, and he uses the Software iSCSI too.

    Regards

    Whow! I installed OpenFiler on my system and what a performance!

    First i tested again the Open-E with IOmeter from a Virtual Machine:

    1 Worker:

    100% seqential, 100% read, 32 KB - 30 MB/sec
    100% seqential, 100% write, 32 KB - 35 MB/sec

    2 Workers:

    100% seqential, 100% read, 32 KB - 10 MB/sec
    100% seqential, 100% write, 32 KB - 60 MB/sec

    Now the values when using OpenFiler on the same Hardware:

    1 Worker:

    100% seqential, 100% read, 32 KB - 43 MB/sec
    100% seqential, 100% write, 32 KB - 30 MB/sec

    2 Workers:

    100% seqential, 100% read, 32 KB - 73 MB/sec
    100% seqential, 100% write, 32 KB - 54 MB/sec

    At last i started a tape restore and and then a IOmeter test from my Workstation with 4! Workers, i got a read speed of 107 MB/sec and have no problems with the restore speed.

    I can start a IOmeter in a Virtual Machine with 4 Workers, they are reading with 95 MB/sec and the 4 Workers on the Workstation are running with 105 MB/sec at the same time....

    And now? My hardware works...

    I will test now with the Open-E again. But first i will load factory defaults, perhaps there are problems in the settings after the x updates...

    Regards
    Stefan
