System Requirements

OMERO.server

The system requirements for OMERO.server vary greatly depending on image size and number of users. At a minimum we suggest:

• Mac OS X 10.5 or later; Windows XP or later; Ubuntu 8.10 or later/Centos 5/Debian Lenny or other Linux distro
• Single core 1.33GHz Intel or AMD CPU
• 1GB RAM
• 250MB hard drive space for OMERO.server distribution
• Java 1.5 or later
• Python 2.4 or later
• Hard drive space proportional to the image sizes expected

The recommended OMERO.server specification we suggest for between 25-50 users is:

• Mac OS X 10.5 or later; Windows XP or later; Ubuntu 8.10 or later/Centos 5/Debian Lenny or other Linux distro
• Quad core 1.33GHz Intel or AMD CPU
• 8GB RAM
• 250MB hard drive space for OMERO.server distribution
• Java 1.5 or later
• Python 2.4 or later
• Hard drive space proportional to the image sizes expected (Likely between 10 and 100TB)

RAM is not going to scale linearly, particularly with the way the JVM works. You're probably going to hit a hard ceiling between 4 and 6GB for JVM size (there's really not much point in having it larger anyway). With a large database and aggressive PostgreSQL caching your RAM usage could be larger but I would surely doubt a large deployment using more than a few GBs of RAM for this purpose, it's just not cost effective.

Summary: Depending on hardware layout 16, 24 or 32GB of RAM would be ideal for your OMERO server. If you have a separate database server more than 16GB of RAM may not be of much benefit to you at all.

CPU is really not something that an OMERO system is almost ever limited by. However, when it is limited it's almost always limited by GHz and not by the CPU count. So you're not going to get a huge OMERO experience performance increase by, for example, throwing 24 cores at the problem.

Summary: Depending on hardware layout 2 x 4, 2 x 6 system core count should be more than enough.

OMERO.insight, OMERO.editor and OMERO.importer

• Mac OS X 10.5 or later; Windows XP or later; Ubuntu 8.10 or later/Centos 5/Debian Lenny or other Linux distro
• Single core 1.33GHz Intel or AMD CPU
• 1GB RAM
• 100MB hard drive space for OMERO.clients distribution
• Java 1.5 or later

Large imports may require 2GB RAM.

OpenGL versions of OMERO.insight

NOTE: These are suggested requirements based on limited testing. Your mileage may vary. Any OpenGL 1.3 capable card should work.

• NVIDIA 7xxx or later GPU; ATI 4xxx or later GPU
• 2GB RAM
