Hardware requirements

Hello,

I’m interested in knowing what others have found suitable for running RT for a 20 person technical support centre with a 9,000 person client community.

Any advice would be appreciated,

We run ours on a dual AMD Opteron 250 with 8 GB of memory. It shares
the box with a lot of other things though. RT doesn’t really need that
much horsepower, but it would benefit to use a lot of RAM.

I’m interested in knowing what others have found suitable for
running RT for a 20 person technical support centre with a 9,000
person client community.

We use a dedicated Dell PE1850 running FreeBSD 6.0/amd64, 1GB RAM,
and a mirrored SCSI disk using Dell’s PERC 4e/Si RAID controller (256
MB cache + battery) and 15kRPM disks.

We run RT installed via the FreeBSD ports system using FastCGI and
Apache. I’m curious what I could do with lighttpd and fastcgi, but
my time is better spent elsewhere than mucking with packages.

The box itself is wicked fast. RT is acceptable on it. I hear 3.4.5
addresses some speed issues (we’re still on 3.4.4)

We have about 8 to 10 reps answering questions from a customer base
of a few thousand. These same reps also answer live chat, so they’re
not always pounding on RT.

The real question I suppose is how many tickets per day you expect.
I think any modern hardware like this could handle several hundred
tickets per day with enough people.

Here is the RT wiki article regarding performance tuning.

http://wiki.bestpractical.com/index.cgi?PerformanceTuning

The key understanding is that the server on which the DB runs needs to
be wicked fast. (No, I’m not from Boston, but have friends who are)

Don’t make the mistake of going with big cheap SATA drives, go with
smaller SCSI drives and arrange them in a RAID 0+1 configuration so that
you get striped and mirrored data sets. With SCSI drives you get
greater parallel drive performance as the actuators can be moved into
position on all drives simultaneously.

If you insist on going SATA, get the Western Digital Raptor drives.
They’re more expensive… look at these graphs

In general, wicked fast equals:

Fast disks + enough RAM for indexes + enough CPU

Disk and memory I/O will almost always be the bottleneck for your DB.

Does anyone know where I can get the hardware
inventory add-on I’ve seen floating about in the RT
community?
I looked on google and the wiki.

Why do you say that? We use 3.4.5 with it just fine.
