Blimey! You obviously know your stuff. So how do you find Gentoo
measures up to Redhat / Fedora on these machines?
Never had an issue with Gentoo on any of them. The SCSI and ether
drivers were well supported.
Other than the CPU/RAM the main different between 2650, 2850, and
2950 was the SCSI card. I'd choose the 2850 over the 2650 given a
choice for anything with heavy I/O and the 2950 are noticeably faster
than the 2850 for our db stuff.
Ours is a 2800, and it's the 2600 that I find most readily / cheaply
available. Looks like the xx50 models are the rack-mount & lower-profile
models of the same generation. Looks like they're more expensive
secondhand and it's not obvious if hot-swap PSUs are available?
I am not sure about the xx00 series, but you could hot swap PSUs in the
xx50 machines.
The machines at this site aren't under high-load, so that's not really a
problem. We like this class of servers for the redundancy of the
moving-and-failure-prone kind of parts (PSU & disks).
If I might ask some follow-up questions:
Are the SCSI cards in these models the same brand / chipset / Linux
driver, please?
Or are they completely different?
Hmmm the SCSI card was onboard and you could get RAID by adding the
memory dimm/unlocker doohicky if your system didn't come with it. We hit
Ebay and picked up a bunch for cheap. Within a series the SCSI card was
always the same other than maybe minor revision. Perc3i ver 3, ver 2,
and etc in the 2600 and then Perc4i ver 1, ver 2 in the 2800.
You'd never have an issue with an early rev or later rev having issues
in any 2.6 kernel I ran.
