FogBugz On Site System Requirements

Operating System

Windows Server 2012 R2 (English version only)


SQL Server 2012


For best scaling and performance, we recommend running FogBugz On Site using separate web and database servers. FogBugz On Site can run on Virtual Machines.


If you’re installing FogBugz On Site and hosting its databases on a single server, we recommend at least 32GB RAM. If you’re hosting your FogBugz On Site databases on a separate SQL Server, we recommend at least 16GB RAM for your FogBugz On Site web server. Both ElasticSearch (installed on your FogBugz On Site web server) and SQL Server benefit greatly from additional RAM. Meeting (and exceeding) these requirements helps ensure optimal performance from FogBugz On Site.

Storage Type

We highly recommend installing FogBugz On Site on Solid State Disks (SSDs). Whether searching or listing cases, planning your development cycles using the Iteration Planner, or querying case data using the FogBugz API, FogBugz On Site uses ElasticSearch to deliver your case data swiftly. Our ElasticSearch usage benefits when FogBugz On Site is installed on SSDs. Installing FogBugz On Site on SSDs helps ensure optimal performance from FogBugz On Site.

Storage type IOPS are recommended per the following:

− Random 4KB Reads: Up to 75,000 IOPS
− Random 4KB Writes: Up to 11,500 IOPS
− Random 8KB Reads: Up to 47,500 IOPS
− Random 8KB Writes: Up to 5,500 IOPS

RAID Setup:

This is optional. If you choose RAID, we recommend RAID 1 or RAID 10.

Disk Space

Installing FogBugz On Site requires 2GB of free disk space. Additional disk space is required for your FogBugz search index, which is stored on your FogBugz On Site web server. This search index can grow to larger than 30GB for installations with heavy case volume.

FogBugz On Site database size can vary significantly depending on case volume and usage patterns. If you’re migrating data from an existing FogBugz For Your Server installation, FogBugz On Site database size and growth rate will be similar. If you’re starting new with FogBugz On Site, heavy case volume and attachment usage tend to most strongly indicate a need for greater database storage capacity. We’ve seen databases ranging from several hundred MB to greater than 300GB in size. Please plan for reasonable database growth over time.

Planning Guidelines

Plan to have 10-15% of your database size as free disk space. For example, if your database is 270GB, you will need 27GB to 41GB for search caching and another 2GB for FogBugz On Site installation files and libraries, or a total of 30GB to 43GB of free space.
