Which Hardware is necessary to server RT?

I would like to know which is the necessary configuration of a server at
hardware level to RT in a small company, 30 users.
Does anybody know?

Thank you!

Mr. Blanco,

It will depend on how many tickets you expect to log in your
system. I would have a system with at least 1GB of memory and
mirrored disk drives for redundancy. We have 2 systems, one for
the DB and the other for the Web server. If one fails, the other
system can take over both functions albeit with reduced performance.

We serve a branch campus of a university. 7 IT staff, approximately 250
users. We are running on a 1 gig PIII, 512 MB, no problems with RT
3.2.2. So far, only about 3000 tickets, though. I can easily see our
needs growing if we get to the point that some others I have seen on
past discussions have.

Thank you!

I believe that will open around 30 tickets a day and 10
simultaneous users in the system.

That’s a pretty lightly-loaded web server.

I would guess you could get away with a cheap Intel server, at least
1GHz and 512MB. You could also get away with software mirroring which
would save you from a drive failure.

A server-class machine (e.g. HP ML150, around $1300) would be great,
but if you have a tight budget you could go with a PC-class machine.

I have a similarly sized installation.

Performance was pathetic on the original machine, a dual-CPU p3-600
with 1G of ram and softare-mirrored scsi disks. It took on average 5-10
seconds for a ticket to fully display in my browser.

after moving to a 2.4GHz xeon with 512M ram performance is much
better, but it’s still not what I would call snappy.

I don’t recall whether this is still an issue with mysql 4 but with
mysql 3 (no longer supported by RT, you need mysql 4 if you do mysql)
you needed to change the default mysql configuration to get it to use
more than some pathetically small amount of RAM. Look at the example
mysql config files that come with the mysql source and/or your binary
distribution (on red hat, look in /usr/share/doc/mysql-something).

that said, telling mysql to use the extra memory helped some on my
p3-600 but it was still heinously slow.

mod_perl can take a fair amount of memory, so you’ll want to budget for
that. I’ve run RT 3.0 on everything from a dual P-III w/ 512MB RAM to a
dual 2.8GHz Xeon box w/ 1GB of RAM. The Xeon obviously was snappier, but
the P-III performance wasn’t all bad. The Postgres backend lived on the
same machine as the web interface in both cases.
