Hello everybody,
I've just suscribed to the list after discovering it recently. I'm not strictly an ISP, but I provide various services for 150-200 users.
I would like to run woody on HP Compaq Proliant ML350 G3 (no choice of the model because of public market reasons). Before buying some machines, I would like to check if woody can be installed on. Actually, colleagues of mine own some (running FreeBSD) and proposed me to try to install woody on one box. The hardware is :
raid controller : smartarray 641 ethernet NIC : BCM5702 (subsystem : NC7760)
This will be my first woody install on raid hardware, so I'm inexperienced.
Colleagues told me that woody install fails due to "old" kernel
2.4.18-bf24 which doesn't include recent modules for the raid (cciss)
and the NIC (tg3 seems better than bcm5700). I've searched the list
archive but I didn't really find an answer.
As of kernel 2.4.23/4 i have been getting some problems with the bcm5700 driver (card's not detected and other things) so i would recommend using the tg3 drivers.
I don't know for sure about the RAID controller [1] but to get the NIC in a ProLiant DL380G3 (a BMC57xx too) working I compiled the driver from Broadcom against a 2.4.18-bf24 source. This way I get modules which can be used with the woody bf24 kernel so I can setup the system and download a newer kernel to the system. Beginning with 2.4.19 you can use the tg3.o module supplied by the kernel...
You can grab the compiled modules from my repository (http://people.iirc.at/moswald/linux/bf24_modules/bcm5700/) or the source directly from Broadcom (http://www.broadcom.com/drivers/)
[1] It may work with the cciss module just as the SmartArray 5i does -
Please note that with the standard Debian 3.0 cd the SmartArray only works in single channel mode. If you use a dual channel config you will get a error like 'can't get controller into duplex mode'. I don't know if this if also true for the 641, but since it uses the same driver i think it is.
Another thing with the DL380G3 (and maybe also the ML350) is that the
(raid) performance is very disappointing. This might have something todo
with hyperthreading / SMP. But i am not sure. I have tested with a
single CPU and in some cases the performance was (much) better.

but I read somewhere about a bug in the driver which wasn't fixed until 2.4.21.
best regards,
Markus
