Well, did it. I finally got Ubuntu 10.04 LTS installed and running on my Net4801 (via PXE netboot install and serial console), and got Lio-Target running on it:

Ubuntu is running off the Compact Flash card. There is a hard drive inside the Net4801 which was used as a block device for the iSCSI target, note the net4801 IDE channel only runs UDMA/33. After testing this, I popped in a USB 2.0 PCI card, and attached a 500GB USB drive. Please see a pic below:


Writing around 1.6MB/sec (CPU utilization ~40%)

Reading around 2.5MB/sec (CPU utilization ~80%)

Please Note:

The test numbers are not exactly correct due to caching Windows performs.

  1. “Please Note:

    The test numbers are not exactly correct due to caching Windows performs.”

    That disclaimer made my day, I just had to burst out laughing.

    (And yes, it’s true, Windows makes use of so-called “aggressive caching” on iSCSI)
