The Dataverse Network Project

Before you install the DVN application, make sure that your installation platform meets the system requirements needed to support the DVN. System requirements are:

• Operating system (OS) - The IQSS DVN core runs under Red Hat Linux 4. 

  You could deploy the DVN-EAR archive on any platform, but currently the scripts to restart and stop GlassFish are built for Red Hat Linux. The DSB component should work under any Linux or UNIX system.
  Note: Red Hat Linux is the recommended OS, because it is the distribution tested most thoroughly.
• Servers – A minimum of two servers are recommended: one server runs the DVN core on GlassFish, and another runs the DSB component on Apache. More servers can be set up for load balancing and storing data files.
• CPU - The IQSS DVN uses two dual-core, 64-bit processors.
• Memory - The IQSS DVN uses a server with 48 gigabyte of memory.
  Development and testing systems require a minimum of 2 gigabyte of memory.
• Disk space - The disk space required depends on the amount of data files that you expect to manage and where you choose to store them. The IQSS DVN file system is a separate server, consisting of a Network File System on a 1.5 terabyte volume.
