Supported Operating Systems

–  Windows (Server 2003 and 2008)

–  Linux (Redhat Enterprise Linux or Centos recommended)

–  Solaris 10

–  OpenSolaris

–  Macintosh OS X Server

Recommended Minimum Hardware

–  Dual-core 2.0Ghz or equivalent CPU

–  4Gb RAM

–  200Gb local storage space

Note that hardware requirements are dependant on the size of the digital collection and the number of likely concurrent users. A single server with the recommended minimum hardware specifications will typically support peak loads of approximately 200 page requests per minute. For large collections source images and METS/ALTO data are typically stored on external storage (e.g. NAS or SAN), while caches and search indexes are stored on local storage space. For very large collections more than 200Gb of local storage may be required. For very busy collections servers with dual quad-core processors (i.e. 8 processing cores in total) and 16Gb of RAM are recommended. For extremely large and/or busy collections it is also possible to split the Veridian™ software installation over two or more servers.
