Sites that do not meet these minimum performance figures are requested to report on the problems encountered to the European Grid Operations Coordination bodies.

EGI documentation

  • Manuals: The EGI Operations Manuals are technical prescriptive documents that provide guidelines on how to accomplish a given task. These documents are periodically reviewed, and need to be followed by all partners (as opposed to a best-practice documents that provide optional guidelines).

A best practice can be optionally adopted by a partner if deemed suitable, the guidelines provided are optional. Nevertheless a best practice is periodically reviewed, and if relevant to grid middleware deployment it is preliminary approved by the relevant Technology Provider. A Best Practice is contributed on a voluntary basis by EGI partners to share knowledge and experience. Contact: operational -documentation-best-practices[at]mailman.egi.eu
  • Procedures: EGI Operational Procedures are prescriptive documents that describe a step-by-step process requiring action from two or more partners.
