Well, the main questions is if DL360/DL320 & OpenBSD is working good
together, the rest is only me thinking out loud :)
They work fine for me.
I have a pair of DL320 G5 machines each with a quad port Intel
Pro/1000 PT card in them and they do all our vlan routing and pass
traffic off into an OSPF area on its way to the internet.
Sounds good. Are you using only these quad ports? Or the onboard too?
Onboard too. I went a bit overkill and bonded everything into pairs.
Onboard bonded crossover cable to the other box for pfsync/sasync
then a couple of other bonded pairs off the quad port card with vlans on
top of that.
Basically, I have 3 more gigE interfaces available should I need them.
(I can unbond one of the pairs - none of them need to be 2 x gigE).
I've been thinking about using one onboard to external, one for pfsync
and then get a dualport NIC where both ports are bonded to the switch.
Since I will do both external and internal routing (but I'm not sure I
will even be able to get that performance out of the box so might be a
none-problem), it would be nice to have 2GBit in case I actually push 1
gig of traffic on the external interface (in which case the internal
would be full too and thus internal routing would suffer)..
You don't happen to have any numbers on performance do you?
Never really benchmarked actually, so nothing specific, no.
I do know that the carp failover is lovely, though. Nothing notices a
box being rebooted (haven't yet tried yanking a power cable).
iLO is fine - just set it up for serial console (if you want a GUI
console you have to buy an 'Advanced iLO' license, but it's really not
needed for a router box). You'll probably want to flip the iLO virtual
serial port to be the 1st serial port, just to make life simpler.
Yeah, openbsd works pretty good with the serial console, but how is it
with BIOS etc? If I recall correct one can access RBSU (HPs rom boot
thingy) etc from text console too. How is it with bootloader support for
console? That works all the way right? Never used it myself in openbsd.
Yep, it all works just fine. There are a few options for accessing the
BIOS I think - text console or a curses-type interface.
The DL320 can have proper RAID, but only if you buy an additional
controller. I use a pair of 80G SATA drives with the onboard
controller and they work fine (the box doesn't really do much disk I/O
- all the network monitoring and graphing is elsewhere).
Yep, thats my plan too (or well 250G since 250G is almost as cheap as
80G, and we are using 250G in other machines, no need for different
spares), and use software raid. One thing I'm worried about though is if
one disk fails, will the BIOS be able to boot from the other disk with a
broken/empty disk in the first slot? I haven't seen any indications in
the BIOS about being able to change, and I've had similar problems
before (empty disk in slot1, disk with OS in slot2, box refusing to boot
since disk1 is empty).
I don't think this will work with the way I have it set up at present.
The trick on Linux is to install the bootloader on disk 2 so that it is
configured to boot from disk 1 (as disk #2 will become disk #1 when disk
#1 is no longer there or operational). I haven't tried to figure out the
necessary magic for that as yet.
