Depending on age of the 1850s and it seems all the 1600s have an issue when Anaconda is trying to detect USB. Do a no usb install on those. Also, on the 1850, if you're using a raid card, you may need to disable the onboard raid as it can be touchy. Otherwise, I have 3000Rs, 1850Rs, DL360Rs (which i won't buy again as these have been the most unreliable) and DL380s, all happily chugging along on ver 3 and ver 4 installs. I did hit some snags with LVM conflicts. I think the proprietary scsi conflicted, but setting up with disk druid has always been reliable.

Let me guess, power supply fan failures on the 360's? If it helps, the newer ones have come a long way.
On topic, I have CentOS on:
DL360G1 DL380G1 and G2 DL580G1 and G2 PL8000 PL8500
No issues on any of them that I can recall.

That's the start, but the replacement was supposed to be 'fixed'. But I don't understand it shutting down instead of issueing a warning when only one of the three PS fans dies. And all this happens almost to the day from manufacture. I had one in a colo situation where they had three... all made within a few months of one another and all had the same failures within those same months of one another.
Then next comes the processor fan........ then the power supply..... then ..... I just think they tried to make it too small (1u) personally. All in a nice clean room with good heating/cooling. The 380s seem to be light years ahead in superiority. I would hope the new 360s are better, but somehow I have my doubts. I'm hearing some grumblings about various blade servers being short lived as well. (and I don't mean 1u servers, even though compaq/hp like to call the 360s blades). I just feel like there are limits to what can be done in a given space... although on many things that space keeps getting smaller.
Gimme' a new version of the Proliant 7000!!! LOL!!! ;)

Greetings!
I wish to thank everyone for their testimony regarding this "CentOS on Compaq Proliant Rackmount Servers" thread.
The basics have been answered and I am grateful.
Even though I can fund brand new shiny latest greatest fastest I think it is a foolish waste of money unless there is a true "need".
Is it currently worth getting used dual PIII 1850R's or should I start with used dual PIII DL380's and like 1Ghz minimum processor speed?
I couldn't find used 1850R's on eBay with more than 600Mhz.
Although there are not thousands upon thousands of clients there is A LOT of bandwidth to service.
Remember, the goal here is to have a bunch of happy little CentOS boxen purring away. :)
I have several custom built units, yet I need more!

The 1850R doesn't go any faster than 600Mhz. The bus on them is 100Mhz. Depending on what services you are going to offer on these boxen and the number of clients being serviced should help you decide on the hardware. I run lots of 1850's serving static webs and SMTP/POP3. My email scanning takes place on Xeon based machines...2Ghz and higher.

Yup, it's a shame to waste expensive horsepower if you don't need it and most web stuff doesn't use a lot of horsepower.. Buy a bit above your needs. Quality over horsepower as well, has been my philosophy.

I would advise going to the DL380 series. These use only the ultra2 or 3 scsi drives.. not the mix of ultra and wide-ultra. I very nice speed improvement. Also, when buying, watch for drives quanity, size and speed (try to avoid the 7200rpm and get the 10 or 15k units). Compaq ram is not your average street ram, but instead meets much higher specs. Genuine Compaq ram can cost a lot used. Watch for machines with the ram you need. You'll also need a Compaq SmartStart CD to closely match the age of your machine. This is used to program bios's on the machine. You can download some flash updates from HP, but the CD can be pretty rich from Compaq.. Finding units with dual power supplies is a plus as well. Most of these items when included with the machine, are much less than buying them individually. I don't know how many times I've relocated a server without ever taking it down by unplugging one PS, plugging it into an extension cord, unplugging the other... might have to disconnect the cat cables for a bit... move it... and never reboot. I run one PS on my batteries, one on another circuit.. so the load is reduced on the backup system. I then power up the other circuit with generator and am not charging the batteries with the generator.... It's very efficient and all set to go at any time.
I couldn't find used 1850R's on eBay with more than 600Mhz.
I think that was the ending point for the 1850s. The DL380s are almost the same unit with a lot of parts being interchangable. The 380s are just more modern in terms of processors, circuitry, raids, drives... and pretty much picked up I think at the 600mhtz point and have grown from there. The dual 866s and up to about 1.2 giggers are very reasonble on ebay
Although there are not thousands upon thousands of clients there is A LOT of bandwidth to service.
A t-1 is still only 1/6th of a ten base ethernet card... and how much power does it take to deliver products at one sixth of a 10base card? Yeah, I know.... it's more complex than that. Database apps can eat up a lot, email/spam systems can eat up HUGE amounts of processing power. But if you're mostly delivering web pages, it just doesn't take much.

I've been extremely happy with all of my proliant servers... heck, I still have one old single 300mhtz running for play! It still runs great! Even has a gig of ram in it. :) I have one dual 333 3000 in use. The next lowest is a single 450 (a colo) and then a single 550 (nameserver only). The rest are duals. Higher up the chain.
A product like MailScanner (set up full blown to do about everything it can), processing maybe 20,000 to 30,000 emails a day, will be about all a single 550 can handle (and that's on the dangerous side). Queries on huge databases will eat up processors... the rest doesn't need much in my opinion.
Best, John Hinton
I run Centos on Compaq dl380g1/2/3's and Dell servers. While the Compaqs are strong hardware they are old and frankly the performance compared to modern (cheap or otherwise) hardware is not really that impressive. A dual 1 gig P3 dl380 and ultra 3 scsi drives get significantly out performed by a generic celeron with software raid SATA drives. I firmly believe the best value for money and performance is the Dell Poweredge 750 with hardware raid SATA drives. The PE 750 is cheap and installs out of the box (Centos 3 and 4), performes flawlessly and is extremely fast.

Strangely enough I just had a quick look on the Dell website and unless I am going mad it appears that Dell is selling the PE750 at 1/2 the price in New Zealand than they are in the US, which is absolutely bizzare. I get a PE750 with p4 3.0 and raid1 160gig sata for 2100NZD = 1400USD, but the same thing on the Dell US site prices up at 3000 USD ? WTF ?

Hmm, if you drop the "gold" support it drops to 1944USD. Still strange, we are used to paying more not less for hardware here in New Zealand.

Do you buy your hardware SATA Raid from DELL?

I'll also add that the "Proliant Support Pack" works as well.
I've just finished installing three DL380 G2's using CentOS 3.x.
I picked up all three off of ebay.....
DL380 G2, dual 1.4ghz, 1-2 gig mem, redundant pwr, redundant fans, 15k 36g x4 drives. Two had the optional SA5i+ (BBWC) raid controller and one had standard SA5i raid controller.
PCI-X,PCI 2.2 and ACPI 1.0b compliant
Two came with complete rack hardware.
Big plus to check for also... Two came with around six months of cpq warranty left.
Paid $1,450-$1,550 + ship.
Very good boxes for the money.
Remember, get serial number and check cpq site for warranty some sellers don't even realize there's any warranty left.
