Compaq ProLiant ML530 (Generation 1)



  • Hello,

    I'm having two issues getting my compaq proliant ml530 (g1) to run pfSense the way I'd like it to be.

    1. I've got two 933 MHz CPUs installed, bios post also shows up two cpus, but pfsense (see dmesg output below) only finds one.
    2. There are 3 NICs installed: two Intel 1000 (em0,1) and one 3com 905-tx (xl0). I've tried to put them onto the same as well on different pci busses, with the same result: On heavy load the interrupt cpu load goes up to 100%.And the throughput stalls around 210MBit.

    Hope a dmesg could provide extra information: http://pastebin.ca/481798
    I'd be very happy if someone could provide a hint what is going on there.
    Using: pfSense 1.2-BETA-1-PRERELEASE-SNAPSHOT-04-23-07-pfSense



  • Not sure why it's only detecting one CPU.

    With a single 933 MHz CPU, ~210 Mb is obviously the best you can do on that hardware. Maxed out on interrupt load means your CPU is a bottleneck.

    If you can get it to detect the second CPU, you should be able to push that over 300 Mb, but don't expect miracles out of CPU's that slow. If you need to firewall gigabit at wire speed, you're going to need a faster processor, even a dual 933 isn't going to cut it.

    On the CPU detection, first see if you can get a BIOS update and updates for any other firmware on the box. I would suggest searching for people's experiences with that hardware and FreeBSD 6.2, might find something useful that way. Also search here on the forum and on the mailing list archives.

    Well fortunately after a firmware update of that Compaq both CPUs are detected (before they weren't even detected on Linux).

    I can't believe that it won't get any faster than that with such hardware. After the second CPU got detected, we now reach 270 Mbits and interrupt CPU load is around 40-45%. (Each CPU around 40-45%) So what could it be that now slows the network?

    Unfortunately there wasn't too many information on the net about compaq ml530 with freebsd 6+ .. but anyway at least the CPU problem is now solved.. Thanks for the hint, maybe you've got another one for the still somewhat "slow" network ..
