If you were just beginning to install your Kerio Mailserver, would you prefer to run it on a Windows or a Mac Server?

We have a 50/50 split of both types of clients.

What are the plusses and minuses of each?

Thanks

Both systems are stable for using KMS, but pc server is cheapest..
(Compare prices of Mac Pro/Xserv vs. HP servers with same hw parameters)

I have KMS on Mac Pro (270 users) and on HP Proliant (40 users).

I prefer Mac servers, but thats just me.

What it comes down to it what you're comfortable with managing.

We administrate four Mac servers and love them for their rock solid stability -- uptime is measured in months (the only time we reboot is for the occasional OS X security update).

Up until last month, our smallest server was a lowly Mac Mini (1.42GHz G4) with 1GB RAM and a couple external drives.

On the high end, we have a Dual 2.0 G5 tower with an internal RAID 1 and an external firewire drive for nightly clones. It serves 140 users like the wind (graphic design users, mind you -- the kind who are complete idiots about 30MB attachments and such).

Beyond that, I'd say seek out as many cost-of-ownership studies as you can find. That's the "true" cost of having a Mac or PC around.

The cost of the hardware might be better for a PC, however you don't need OS X Server to run KMS, you can use OS X Client.

If cost is TRULY a concern, run a Linux distro on a homemade server.

Are you asking me this question?

Yeah, there's a bit of a difference between Windows, OS X, and Linux.

Another thing to consider is the type of file system each OS uses.

We were running KMS on a quad core MacPro with an X-Serve RAID attached as storage. The HFS+ file system was problematic and we would experience severe lock ups on occasion. When Apple announced no official support for ZFS on OS X we migrated over to RHEL5 which uses the ext3 file system and no longer experience lock ups.

In a smaller organization I wouldn't think the type of file system is all that important but for us it necessitate a change in OS. We have approx 400 users using Entourage and connecting to KMS as an Exchange server. We also have approx 40 or 50 users connecting via ActiveSync.

I've never seen problems with HFS+ and servers. Are you sure it was a HFS+ bug, or could it have been directory corruption or bad hardware?

Pretty sure it's an HFS+ bug and deals with a very large number of files being accessed. Seeing as how KMS does not use a database every email, contact, calendar even etc is a file.

The MacPro and X-Serve RAID we were using for KMS have been repurposed and placed in our production environment. We've had no issues what so ever with either.

Interesting, can you give an approximation on how many files there were on the RAID?
