Greetings. We're looking at buying a new server to use as our LTSP Terminal server, along with all our general server needs such as IMAP email, MySql database, apache webserver for internal web-development use (not external), and the like. It will service about ten concurrent users.
We've spec'd out the server below from Dell. It's probably more machine than what we need, but the way Dell has the pricing on this system right now, most of the less powerful systems that I have looked at with similar configurations either cost more, or aren't enough less to warrant getting them instead of this one. In a nutshell, this system Dell PowerEdge 2900 with two Xeon dual core processors, 8 GB Ram, with two 146 GB SCSI 10k rpm hard drives in a hardware Raid 1 configuration, for $3,482.00. Few questions: 1. Someone told me I should not set it up with Raid 1 -- that I should set it up with three 73 GB hd's. He said it would be faster than the Raid 1. I don't know much about Raid, but I gathered that Raid 5 should be slower than Raid 1 -- if not in the writing, than at least in the reading. Which should I go with -- 1 or 5? Any opinions? He also said that in a Raid 5, if one drive went out, the other two would just pick up and run without the other drive until I could replace the faulty drive, without me having to do anything. Is that right? 2. Do the drives in either Raid 1 or 5 have to be *exactly* identical? That is, if a drive fails a few years from now, and I can't get an exactly identical drive to replace it, will I be ok as long as I can get one that is the same size, although perhaps a different brand or model? Or would I have to replace all of the drives? 3. If I go with a Raid 1, is one hd Raid controller enough, or should I get two? I know one will do the job, but would two be better? (Like I say, I don't know much about Raid. This will be my first experience with it.) 4. Should I load the 64-bit version of SuSE on it, or the i386? From what I understand, there are fewer software packages available for the 64-bit system. (Do I even have the choice with Xeon processors?) I need Java, OpenOffice, a web browser (preferably Firefox), MPlayer plugin, Perl, and Php to work. 5. I thought I read somewhere you can run 32-bit software on a 64-bit system, but that it only runs in 32-bit mode. What's the deal with that? (First time for 64-bit for me, too.) 6. I've priced systems with HP and Gateway, too, and they seem to cost more than Dell for less powerful systems. Where do you all get your servers? Do you build them yourselves? If so, is there a better place to get the components than Tiger Direct, PC Connection, JDR, and CDW? What processors do you all recommend? 7. The 5-year old Dell PowerEdge 1400SC server we have has never really been all that stable. I have to reboot it every week, and sometimes it still hangs during the nightly processing (backups, etc.). And this is true regardless of what flavor of Linux I run on it. It runs ok once I reboot it, but it's a pain in the neck. Does anyone else have problems with Dell PowerEdge servers? 8. Any other comments / suggestions about the system we're looking at buying? I would greatly appreciate any and all advice. I don't know that much about all this kind of stuff, and these are some of the questions and concerns I have. I wanted to run it by some others who do know about this stuff, and you all are the nicest group of people I know that I can ask. So like I say, I'd really appreciate any advice you all offer.
