Hi Marc,

Install OpenManage Server Administrator on that system. It will provide
you GUI or CLI interface to configure the SOL.

Here you go for OMSA latest release

Thanks very much Tino & Patrick.

I am guessing the same goes for the SAS6/iR too.

Thanks, looks like 6 volumes is probably supported. I plan on
configuring it
via the BIOS if at all possible.

Of course, some benchmarking will be done before we put the box in
production. The server today has about 15 million small files. (Another
reason for splitting it up.) ZFS on Solaris doesn't have a problem with
that. but I can tell you that the SUSE 9, + Escalade controllers + 7200
RPM
sata drives (|-p) server that is being replaced does have a problem.

It isn't just the hardware , there is a substantial performance
difference
between ext3 and XFS filesystems on the box, with XFS having a 10 or 15%
edge. If I can get the controller in this new box to be the bottleneck
I'll
be happy. We have an R510 in production now as a file server, with one
big
RAID6 array, and so far I can get 500 or 600 iops/sec out of it, as far
as
benchmarking a production server goes. I'd be real happy to hit 800.

I think it's the former.

We bought a load of R410s with 4 disks in RAID10.

We then bought another batch, exact same config, but were tld that we
couldn't order them with RAID10, so we had to order them with RAID5 and
reconfigure as RAID10 when they arrived. As it happened, half the batch
came with RAID10 anyway!

Depending on your application, it might be worth using RAID10, ie.
creating a large stripe out of your mirrored pairs.

Don't forget to buy battery-backed cache.

Rest assured, it works really very well indeed. I've used a couple of  
external network KVM units, or "KVM-IPs", whatever you prefer to call  
them, and the DRAC4 is really top-notch.

It's the only downside of the DRAC, IMO. The 3rd-party KVM-IPs I've  
used have at least supported Macs; my current one allows viewing with  
a standard  VNC client, which the DRACs do not, but does not offer any  
remote media. My last one (actually I still have it here, I need to  
sell it) offered remote media (including booting) by pasting the URL  
to a Samba share into its web-interface. You might have success with  
the Firefox under Linux, but only a specific version, on Redhat, was  
officially supported.

The one I have is the DRAC 4/I, don't know the part number, on a  
PowerEdge 2800. I would *assume* that different models of the 4, i.e.  
the 4/S or the 4/X or whatever, would be basically the same, offering  
the same facilities but for different models of PowerEdge.

Not addressed to you, specifically, but for the benefit of others:  
watch out for the 2650s, which offered a DRAC option, but came with a  
"RAC" as standard. The RAC is rubbish, a poor relation to the DRAC,  
although not too bad as a freebie - the viewer is really inadequate,  
and IME may not work when you need it to; the remote power functions  
are all I've found it good for.

Correct. Reconfiguration is supported by the PERC series of controllers
only (with the exception of the PERC H200).

Hello list,

I'm looking to setup Serial over Lan on my cluster of PowerEdge 1950's.
Does anyone have this setup?

I'm kind of confused on how all the redirection works.  From posts that
I
have read, we redirect console to a serial port, then tell the BMC to
forward the serial console to the LAN.  But my BIOS has a 'Direct
Connect'
mode.  My IPMI doesn't have any of the Serial redirect.  I fear that I
am
confusing IPMI and BMC somewhere too.  Could some take a stab at
explaining
this please.

One further question. If I do get this setup, does it give me 'full
console
access' over serial. In other words, do I get the BIOS POST, or does the
serial console only come up after post?  I am aware that I need to setup
my
OS (Centos) to spawn a serial tty, and this I have done before, just not
over baseboard LAN.

Pointers to docs accepted at par. :)

-- Marc
