Hardware for a small environment

[Athena]

Hello,

We plan to deploy the Windows package for 5 user accounts, registering 50-100 tickets/day.

The installation guide mention the following HW requirements :

"You can also run it on Microsoft Windows. OTRS does not have excessive hardware requirements. We recommend using a machine with at least a 2 GHz Xeon or comparable CPU, 2 GB RAM, and a 160 GB hard drive for a small setup."

How many 2 GHz cores are needed ?
Is 2GB just for OTRS, or is it 2GB for OTRS + Windows ? Is it saferto ask 4 GB ?
Does the 160 GB HD includes Windows 2008 R2 (40 GB) or not ? So, do I need 160 or 200 GB ?

Thanks in advance for your help.

Your deployment is small enough that any hardware you throw at it will be adequate.
If you have it, 4GB is better than 2GB.
Drive space requirements depend on expected attachment size. By default, attachments are stored in the database as BLOBs. However, this can be changed to FS/FileSystem, and if you're planning on large attachments, you might consider looking at storage at roughly zero compression. Other size issues are not as relevant. General transactions are small and don't take up nearly the amount of space as attachments.

Your deployment will/should be far less than 1GB for all parts of OTRS (not counting OS). Attachments and cache storage will increase this, but, depending on expected attachment size, you may be a few years out before you'd hit any limit with 100GB free space.
