We definitely sell PowerEdge systems without an OS and have for quite a
while. However, we do limit configuration for higher end systems to include
My appologies. I may misremember. I purchased the machines (twelve T5500s,
four R815s, and four C6145s) about 5 years ago and don't remember precisely
the arrangements. I'd have to check archived email to know for sure.
The machines were purchased through ECN (Purdue's Engineering IT services). I'm
a lowly professor. But I software-maintain my own machines. I definitely
didn't spec out a hardware RAID controller. The mechanisms by which one was
included are unclear at this point.
There's definitely a PERC controller in there based on <https://lists.debian.org/debian-user/2016/06/msg00934.html>
"05:00.0 Serial Attached SCSI controller: LSI Logic / Symbios Logic SAS2008 PCI-Express Fusion-MPT SAS-2 [Falcon] (rev 03)"
I'm not seeing the subvendor/subsystem ID's there but it's presumably the
PERC 6/i. If you're really not using it at all, you might be able to pull
it out if the driver for it is causing problems. However, I suspect you
need it to connect to the drive backplane. Stuart (CCed) may be able to
offer some more insight into driver issues you might see.
The SATA controller should only really be in use by the optical drive if
present. Some of the mid-tier systems of that generation support SATA
drives connected directly to a controller on the motherboard, but support
for that under Linux was spotty from my recollection.
My T5500s have optical drives. But neither my R815s nor my C6145s have optical
drives. All my machines have SATA drives. The R815s in question each have
six ST9500530NS drives. They have been running squeeze and then wheezy with
software RAID for 5 years since purchase.
Now that I have someone from Dell on the line who appears to be
Debian-friendly, it would be nice if you made firmware upgrades
Debian-friendly. I have been able to apply
but have not been able to apply
(I don't even know if either of the ESM upgrades are for my hardware. But the
shell scripts don't run.)
