 If you can go beyond the big vendors, you might also look at smaller
 companies that support OpenBSD.  Iron Systems, Sera Systems, etc.

 It's difficult at best to determine from their documentation which
 model from which major vendor is fully supported by OpenBSD.
 
 For some Dell desktops, they don't even make it clear if the server
 comes with EIDE or SATA disks, much less whose chipset is used,
 and looking at servers from Dell and IBM, they just state embedded RAID
 and if I ask about which chipset is in which model, the sales rep points me
 towards their download area for MS-Windows drivers.
 
 Dell is getting better about giving details, but there are still caveats.
 Our 2650s all have Adaptec 'aac' RAID chipsets and won't boot 3.7 GENERIC,
 while the newer 1850/2850 machines work under 3.7 but the 'ami' RAID
 controller isn't detected correctly by earlier releases.
 
 Rather than buying hardware blindly and hoping for the best,
 reading the archives and then posting to misc@ is how I hedge my bets
 when ordering new servers from Dell, Sun, etc.

Hogwash. It is when the machine doesn't run OpenBSD. Not all of mine
do.  and I don't count on *any* vendor other than OpenBSD doing
anything like W^X on i386. (i.e. solaris, windows, etc.) I do expect
in the next year or two we will see stuff making use of the nx bit in
places where I redeploy some of these where I would not see that if I
had bought i386 only hardware - which means it may (if they

untill it falls over from metal fatigue. I have to think 4-5 years

Re: 1U server recommendation

2005-07-28 Thread Bob Beck
We are running production web servers on OpenBSD running on IBM
325E's as well as Sun V20Z's, running OpenBSD. We've had decent luck
with both the i386 and amd64 distro on those.  I have used a demo HP
with good success too, but don't have one in production anywhere. 

I'm not using the internal raid stuff. Most of our
web servers are just that, and run off an ide disk using
an external data source (nfs or database). They then sit behind
a pair of carp/pfsync load balancers that advertise the address 
used to hit them, and then redirect to a pool of these servers
using round-robin sticky-address, so I'm using redundancy at the
whole machine level rather than just worrying about the disk. 

For those machines where I do use raid, I'm using 
a dell perc4/DC card stuffed into the machine (it's an ami
under OpenBSD) hooked up to a Dell 220S u320 scsi jbod. We are
using these for Database (mysql/horde), AFS, and NFS services.
(FWIW, we purchased 27 IBM 325e's and 9 V20z's about 6 months ago). 

Only thing to note in this case is that if you run i386 instead of
amd64 on them, you should used 3.7-stable or current to get the
locore.s and apm.c fixes so that apm doesn't make your I/O go
appallingly slow. The other alternative is to use config -e to disable
apm in the kernel, at which point you won't be affected. 

I use serial consoles exclusively on them, hooked through cisco
2511's talking to a private network behind an openbsd box running
conserver. The serial bios's are usable in both of them but need to be
configured so that serial redirection happens out com port A, and is
*disabled* after boot. (the default is for it to remain enabled). You
then tell OpenBSD to use a serial console in the usual way. 

Just my experiences.

On this subject, I am looking for a good dual-processor AMD64

Then my reccomendation under your supported hardware agreement
is exactly what I use:

sun V20Z server
Dell Perc4/DC raid card
Dell Jbod (i.e. 220s or something) hooked up to the PERC card.


 While Sun is offering some very nice AMD64 (and Sparc64) kit,
 Sun just never seems to understand that customers want
 embedded hardware RAID controllers on the motherboard.

While it would occasionally be nice I find the embedded stuff
is usually garbage, and you can only have 3 drives in a 1U chassis. 
at the point I'm going to do this I'd just as soon have two machines
with one drive and do the redundancy between machines instead of
trying to make an ultra reliable 3 disk setup on crap. 

When I do want it reliable, I do what I suggested to you above.

 I run heaps off Dell PowerEdge 1550, 1650, 1750 and 1850 without issues.

Similar results here.

The PE1850 is a solid machine, with (optional) dual power supplies, hardware
mirroring SCSI controller, and if you really want to get crazy, you
can even configure
it to use half the RAM as a spare bank so even a DIMM failure won't take the
server down (haven't tested this personally).

Some PE models can be ordered with your choice of embedded 'bge' or
'em' interfaces, go with 'em'.  Same goes for the RAID controller --
not all PERCs are the supported 'ami' LSILogic MegaRAID chipset;
the PERC4/ei in the 1850 is supported as of 3.7.


Lastly, most (all?) current PowerEdge products can be configured for
serial console in the BIOS, many have optional (not OpenBSD supported)
DRAC network management daughterboards for remote recovery from just
