What's an appropriate level of server hardware to have for SME?
I saw a post discussing X86_64 CPU support and other discussion on RAID which seem to be included (possibly) in SME 7 but I have not found any specifics about this.
More to the point, I only wish to support anout a dozen (or so) workstations. Is considering X86_64 & Hardware RAID5 overkill for this size of task?
Also, what are the thoughts on RAM for this size of task/duty?
Thanks...

X86_64 is not supported in SME. It will load OK put will not run in 64 bit so it would be a waste of money buying a 64 bit processor and board. Software RAID5 is supported.
As for the size of your network, I have a network that had 5 workstations doing fairly heavy file sharing, 3 website and mail server in server/gateway mode that hummed along very nicely on an Athlon XP1600, 512 Meg of ram and IDE drives running in SW raid1.
It started to get a bit slow when I added 5 more workstations so I decided to kick the processor up to an XP2000 but that hardly did much. I read around and found out that Linux uses memory very efficiently so I decided to add 512 Meg more. That really did the trick. I put the XP1600 back in and it works as well as the XP2000 which shows me that memory plays a large role.
I now have several servers up that all have XP1600-2600. You can buy these very cheap and they make great servers. I always put a Gig of ram in, it just seems to really speed the server up under heavy file serving.
I have not tried the raid5 yet but plan on it soon.
All-in-all it really depends on what the workstations will be doing. If they will be using SME as just a gateway then you won't need much. If SME will be serving up a lot of files, running a few web sites and serving up email and printers, then I suggest stepping it up. What exactly will the server be doing?

PS. I have SME7pre1 running on an AMD K6-200 (that's right 200mhz) with 256 Meg. It will load and run but is slow. It is my home gateway and only has 1 very low traffic website on it and is just for testing. Just wanted to see if it would load and have been using it for a few weeks now as a test server. It actually surprised me and does very well under this small load.

Thanks for the post. That's the kind of heads-up info I am after.
Is there anyone else who would like to offer their thoughts &/or experiences?

I installed e-smith around 6 years ago for my wife's 3 workstation lawfirm. 3 years ago I upgraded them to a Dell server with hardware RAID. It currently runs SME 6.0 and they use file services & email mainly. The onsite h/w maintenance expires in July, and I probably need to get them to buy a new server, if only to continue to have next day on-site maintenance.
The comments about RAM and 64bit CPUs are useful.
I hope that by July there will be a v7 production release.
In the context of V7, Are there any views on:
H/W vs S/W RAID
SATA vs IDE
Intel vs AMD
Dell vs other UK available vendors offering 3 year onsite support and tolerant of Linux installations

Hi,
i am running law-firm office here with 5 - 10 WS (varying on workers on duty).
Server/Gateway with static IP, lots of mail and complete filesharing and printing.
Server is SME7pre1 running very nicely on a Athlon XP1700 Asus MoBo A7N8X-E (1 GB RAM, 1 onboard GB-NIC for LAN and 1 more for Internet).
HD is two WD Caviar 36GB in Raid1.
Memory is more important as stated before. With PIII800/512 MB Ram we were slow before. CPU does not matter so much.
I hava a 3ware SATA Raid5 controller lying around here from our old win2k Server. I will give that a try. But i will use hw-raid5 then (3*80 GB disks), because that to my experience it is easier to backup/image and easier to restore even on other hardware than software-raid.
Do not forget backups. I am running a HP tapestore 36 GB tapedrive in the server. Bought that one cheap at ebay. Modified backup-script to do weekly full backups to tape. Backup2ws daily for ibays with data and weekly 1 full backup 911 without ibays.

At home, i've got a sme server running very nicely on the following:
-AMD Duron 900Mhz
-Gigabyte Ga-7IXEH
-512MB Ram
-Seagate 80GB ATA-100 HDD
-52x CDROM
-2x 3com 10/100 Lan Cards.
-32MB TNT2 Riva Graphics
It just works brilliantly.
It is hosting two internet domains (email, web etc)
It is also a proxy and content filter for my local network.
Really, anything from 500Mhz upwards with 128MB RAM should let you test SME in a development enviroment nicely. But when you want to use it for an office etc, then you want more reliability, so maybe 1+Ghz with 512+MB RAM. But it really depends on your budget, and how many workstations your server is going to serve.

I can and have built a succession of servers using motherboards, processors etc for home use running SME Server. However for my wife's business, I want them to be able to call out someone else if their hardware goes wrong. I has to be a PC manufacturer that doesn't disappear one day, as has happened so often in the UK to local companies. So I guess I am stuck with the likes of Dell who sell direct with on site service. Hence my questions above, which would affect my choice of model - So if anyone has anything to say about the current range of choices for CPU, RAID etc, please contribute!

I played around with the Dell (UK) website, and came out with a reasonable server for £986.
-3.2Ghz Intel Xeon (2MB Cache/800Mhz FSB)
-1GB RAM (2x512MB DDR2-400)
-2x160GB (SATA/7200rpm)
-48x IDE CD-ROM Drive
-Integrated 1000MBit LAN (First Card for LAN)
-Intel Pro 100MBit Network Card (Second Card for WAN)
-56K Lurch Modem (Maybe for Hylafax)
-Dell USB Keyboard
-Silver 3 Yr (24x7) Premier Enterprise Support
Now just to wait for SME7 final

That setup will for sure do the trick and very nicely at that!!! :-D

From previous posts, the CPU is not the most critical item, and so I thought a 2.66GHz Celeroin would be adequate.
The current system has a pair of 80GB drives, with h/w RAID controller. The "backup & restore" panel says only 8GB of the dirve is in use, so there seems litte need to increase the capacity.
I presume that the SATA presents no problems for SME v7. However I am unclear what Dell mean by "Raid Connectivity C2 Onboard SATA, Two Drives connected to Onboard SATA Controller". Is this a hardware RAID capability, or merely an invitation to use software RAID? One of the posts said that H/W RAID is preferable.
I also want tape backup, and the Travan is what is already installed, and works with the existing system. Would a backup tape from SME Server V6 restore onto a clean install V7 without problems?

C2 raid is software raid, the SC430 does not support onboard HW raid.
The prev SC420 had onboard HW raid.
I got a Dell CERC for the raid part ;-)

.. for thise budget conscious people try an older Compaq DL380 (G1).
If you can live with the noise you get dual PIII, to 4GB SDRAM ECC, 3 Hotswap SCSI drives, caching SCSI RAID, hot swap PSU's, rackmount.
Here in Oz these can be had in a variety of configs for very little money (buy a 2nd as a spare!) and run fantastic; want a bit more grunt for that overloaded mail/web server then try an ML530 PIII Xeon.
Can't beat these enterprise servers for robustness and reliablility when combined with the $$$ figure attached.
Cheers
