3. Details of the initiative

This particular DR scenario simulates a complete outage of the entire Equinix data center (FR2) facility. In such a disaster recovery scenario, Deutsche Börse Cash Market’s T7 infrastructure regularly used for its T7 simulation will be re-used to serve as disaster recovery production infrastructure.

During the DR test exercise, production reference data will be used, including User IDs, T7 GUI SSH keys and ETI sessions. Changes which have been made to this reference data will NOT be copied back to the production environment after the test. It is not advisable to perform any changes to this data during the test exercise.

While order entry, modification and deletion will be possible during the DR test exercise, any order book or trading information created during the DR test exercise will NOT be transferred back to the production environment.

The following Cash Market T7 interfaces will be available during the DR test exercise:

  • Xetra T7 Trader- and Admin-GUI
  • Enhanced Transaction Interface (ETI)
  • Xetra Market Data Interface (MDI)
  • Xetra Enhanced Market Data Interface (EMDI)
  • Enhanced Order Book Interface (EOBI)
  • Reference Data Interface (RDI)
  • Reference Data File (RDF) from production - provided on request 
  • Common Report Engine (CRE)

Trading Participants taking part in the DR test exercise can expect to receive market data via MDI, EMDI and EOBI, can read reference data via RDI or request RDF from Customer Technical Support (CTS). Order and quote entry will be possible via ETI and Trader GUI. 

The following Cash Market T7 interfaces will NOT be available during the DR test exercise:

  • Extended Market Data Service
  • FIX Trading Interface

CCP will not be participating in the DR test exercise. The disaster recovery test for the T7 Börse Frankfurt System will provided at a later point in time and further information will be provided at the appropriate time.
