Introduction
This document provides an overview of Deutsche Börse’s disaster recovery concept for the T7 trading system.
It contains the required technical background information as well as functional features and limitations toenable participants to continue trading in a DR situation.
Please note: Chapters 2 and 3 describe the general set up of real DR scenarios whereas chapter 5 focuses on
the DR test exercise, describing which interfaces and functionalities are in scope of the disaster recovery test
exercise and which are not.
Participation in the T7 disaster recovery test exercise is not only strongly recommended by Deutsche Börse but
it is also seen as an essential part of the industry’s disaster recovery readiness.
Therefore, Deutsche Börse kindly requests all Trading Participants to take part in the T7 disaster recovery test.

For an overall description of T7 network options, please refer to the document “N7 Network Access Guide“,
also available on the Eurex and Xetra website:www.eurex.com -> Support -> Initiatives & Releases -> T7 Release 12.1 -> Network Accesswww.xetra.com -> Technology -> T7 Trading architecture -> System documentation -> Release 12.1 -> Network AccessGruppe Deutsche Börse

Disaster recovery scenarios

2.1

Status quo
The following drawing describes the different connection possibilities to the primary data centre.
Three types of customer installations have to be considered:•

Customer installations inside the primary data centre (co-location)•

Customer installations connecting to the Frankfurt Access Point•

Customer installations connecting to remote Access Points (London, Chicago, etc.)

Figure 1: All three types of customer installations and their redundant connectivity to the T7 production back ends.

Figure 2: Disaster recovery scenario 1

In such a scenario, customer installations connecting to remote access points (i.e. London, Chicago, etc.) willcontinue to use both leased lines connecting them to the local access point. The local access point continues touse backbone lines to Frankfurt which are terminating in the secondary data centre.
Customer installations connecting to the Frankfurt access point will be able to continue to use a single leased
line connecting to the access point half located in the secondary data centre.
Customer installations within the primary data centre are considered to be non-functional in this DR scenario.

DR scenario 2 - Partial loss of primary data centre, co-location still accessible
Figure 3 displays the result of a DR scenario that renders the T7 back end of the primary data centre (FR2)
inaccessible. The co-location facility is still accessible. Co-location customers are still able to access the DR data
centre.

Figure 3: Disaster recovery scenario 2

In such a scenario, only the T7 back end located in the primary data centre will be considered to be nonfunctional.
Customer installations connecting to remote access points (i.e. London, Chicago, etc.) will continue to use bothleased lines connecting them to the local access point. The local access point continues to use backbone lines
to Frankfurt which are terminating in the secondary data centre.
Customer installations connecting to the Frankfurt access point will continue to use both leased lines
connecting them to the access point half located in the secondary data centre.
Co-location customers will be able to continue to use their existing connection to access the DR environment.

General considerations
In a disaster recovery scenario, the T7 infrastructure regularly used for T7 simulation will be re-used to serve as
T7 disaster recovery production infrastructure.
The switch of the back ends and the transfer of reference data will not be instantaneous but is expected to takeup to two hours.
While most T7 interfaces will be available in the disaster recovery scenario, several conceptual differences toregular production exist and have to be accounted for.

3.1

Functional•

Order books will be empty after switch to the DR environment.

•IDs (MatchStepID, EventID etc.) are reset and start from “1” again. Timestamps must be used to detect
duplicate IDs.

•

OrderIDs are based on timestamps, no further action required.

•

Trades of the current business day will not be transferred to T7 DR System but can still be inquired fromthe respective Clearing systems.

•

T7 DR system will start with an empty trade data base. However, on-exchange trades as well as match
numbers reported in a DR scenario will start with an offset of 5.000.000 whereas TES trades will startwith an offset of 1.000.000.

•

Intraday defined strategies will not be transferred to the T7 DR system.

•

Cover activations will not be transferred to the T7 DR system.

•

Number of partitions in DR is lower than in Production and therefore the product assignment topartitions will differ.

•

A new reference data file (RDF) will be produced during DR start up and will be published by the DR backend (as well as further intraday updates) onto the Common Report Engine into the respective
production directory.

3.2.2.1•

User IDs, ETI and FIX LF sessions will be used from production.

•

All TCP and UDP Ports will be the same as for normal production.

•

Multicast Groups will be the same as for normal production for the following T7 broadcast interfaces1:
o Market Data Interface (MDI)o Enhanced Market Data Interface (EMDI)
o Extended Market Data Service (EMDS)
o Reference Data Interface (RDI)•

Rendezvous Points (RP) will be the same as for normal production1.

•

Technical Heartbeats will be the same as for normal production1.

•

CRE Subnet will be the same as for normal production.

Different in comparison to Production•

ETI Trading Gateway and Partition Specific Gateway Subnets will differ from regular production.

•

FIX LF Gateway Subnets will differ from regular production.

•

GUI Landing Pages, Webstart Servers and (Crypto) Proxy Servers will differ from regular production.

•

Stream-A multicast groups for Enhanced Order Book Interface (EOBI) will differ from regular production(Stream B for EOBI is not available).

•

Source IP addresses will differ from regular production for the following T7 broadcast interfaces:o Market Data Interface (MDI)o Enhanced Market Data Interface (EMDI)
o Enhanced Order Book Interface (EOBI)
o Extended Market Data Service (EMDS)
o Reference Data Interface (RDI)

Enhanced Order Book Interface (EOBI)
Deutsche Börse offers the possibility to receive EOBI data in case of a Disaster Recovery scenario.
In DR scenario 1, customers connecting via leased line, who have access to the regular “A” multicast streams,
will be able to receive EOBI data using dedicated EOBI multicast addresses (see chapter 4 for network details).
In DR scenario 2, co-location customers will be able to receive EOBI data using the dedicated EOBI multicast
addresses via their cross-connects ((see chapter 4 for network details).
Please make sure that your internal firewall settings are adjusted accordingly.
Please be aware that Stream B for EOBI is currently not available in DR.

1Stream B Multicast Groups, Rendezvous Points and Technical Heartbeats will only be available for DR scenario 2

3.3

Accessing ETI HF Sessions in a DR scenario
As mentioned in Eurex circular 005/23 and Xetra circular 002/23, the use of ETI HF production sessions has
been restricted to the Exchange's Equinix FR2 facility (non-public ground). The use of ETI HF production
sessions from other locations is no longer possible in the T7 production environment.
Please note that in the event of a disaster recovery scenario, it will however still be possible to use ETI HF
production sessions from locations outside the Exchange's Equinix FR2 facility to access the PS gateways of the
T7 disaster recovery environment.
For more detailed information, please refer to the related circulars which are available on the Eurex and Xetra
website:Eurex Circular 005/2023
Xetra Circular 002/2023

3.4

Return to Production
After the DR scenario has been resolved, Deutsche Börse will communicate the procedure for re-establishing
the connection to the production environment with adequate notification time.
For more detailed information, please refer to the document “Emergency Playbook on Incident Handling”
which is available on the Eurex and Xetra website:

4Disaster recovery network details
Due to the nature of the distributed T7 architecture, different interfaces will be configured in varying ways.
T7 interfaces whose production infrastructure is solely located in the primary data centre will switch to thesimulation infrastructure and need to be accessed via simulation network addresses (i.e. ETI gateways, FIX LF
gateways).
Other T7 interfaces whose production infrastructure is distributed across both data centres will be able tocontinue to use the existing/remaining production infrastructure in the DR data centre (i.e. multicast addresses).
On the following pages, you can find all available T7 interface connection details in a disaster recovery scenario.

4.1

Ping test
Due to the previously described concept, all needed IP addresses (except EOBI multicast address range, seechapter 3.2.2.1) are already in use either in T7 production environment or T7 simulation environment andaccessible at any time. Because of that set-up it is not necessary to offer a dedicated ping test prior to the disasterrecovery test exercise.

Disaster recovery test script
Deutsche Börse’s disaster recovery test exercises will be performed twice a year on a weekend (usually
Saturday).
These exercises will be conducted for the markets Eurex, Xetra and Börse Frankfurt. Please inquire with therespective partner exchange to find out whether and to what extent it participates.
During a DR test exercise, production reference data will be used, including User IDs, T7 GUI SSH keys, FIX LF
sessions as well as ETI sessions.
The business date for the DR test exercise is "DR test calendar date – 1 business day" (e.g., DR test date: 5
October 2024, therefore business date on the DR system: 4 October 2024)
Please note: Changes done to any reference data will not be copied back to production after the test. Please
do not perform any changes to this data during the test exercise. Any order book or trading information
created during the DR test exercise will not be transferred back to production.
Please be aware that trading participants are responsible for adapting their internal infrastructure andprocesses to ensure that no internal test data (orders, trades, etc.) generated during the T7 disaster recovery
test is transferred to downstream production systems.

5.1

Disaster recovery test scenario
The DR test scenario will simulate an outage of the regular T7 production system which is hosted in the primarydata centre facility (see chapter 2.3 ).
However, this DR test scenario will not simulate a complete data centre outage, which means that co-location
customers will also be able to participate during the test (DR scenario 2).
In such a disaster recovery scenario, T7 infrastructure regularly used for T7 simulation will be used to serve as
DR production infrastructure.

5.2

Schedule of the disaster recovery test
Planned start DR test:

13:00h CE(S)T

Planned end DR test:

16:00h CE(S)T

Planned start re-connection test on production:

17:00h CE(S)T

Success criteria for the disaster recovery test
The disaster recovery test exercise can be regarded as successful when•either a message “Connection Test #####1 <hh:mm:ss>” appears with an increasing sequence numberin the News Board of the T7 Trader or Admin GUI•

or a successful session or trader login via ETI has been performed and MDI2/EMDI/EOBI2/RDI
heartbeats have been received.

•or a successful session or trader login via FIX LF has been performed and MDI2/EMDI/EOBI2/RDI
heartbeats have been received.

5.5

T7 Trader GUI
T7 Market Data Service (MDI)
T7 Enhanced Market Data Service (EMDI) – not applicable for Börse Frankfurt T7 (XFRA)
T7 Enhanced Order Book Interface (EOBI)
Please note: Unlike the other market data interfaces, EOBI will be accessible via dedicated multicast
addresses. Please make sure that your internal network/firewall/switch settings are adjusted
accordingly.

DR test exercise: Availability of reference data
During the disaster recovery test exercise, participants will be able to••read reference data via Reference Data Interface (RDI) (see chapter 4 for network details).
receive the Reference Data File (RDF) via the Common Report Engine (CRE)
Please note: In a real DR situation, the RDFs will be transferred in the production folder.
During a DR test exercise, RDF data will be distributed in the simulation folder.
The files can be easily identified as test files because the DR environment number(s) will be used for
its naming convention.

DR test exercise: Common Report Engine (CRE)
Participants will be able to access the Common Report Engine to receive RDF test data in the simulation folder(in a real DR situation the RDFs will be transferred in the production folder as usual).
The files can be easily identified as test files because the DR environment number (45 for XEUR, XEEE, XETR,XMAL and XBUL, 41 for XFRA) is used for its naming convention.
However, no further reports will be generated during the disaster recovery test exercise.

5.10 Re-connection test
After the disaster recovery test exercise has been completed, the regular production environment is planned tobe made available from 17:00h CE(S)T until 18:00h CE(S)T for a re-connect test to allow participants to re-test
their infrastructure in the production environment.
The T7 production environment will be shutdown afterwards and will be re-started for the next business day
on Sunday evening, at the usual time.

5.11 Support
The Technical Key Account Managers will be available for supporting the disaster recovery test exercise via
your individual VIP number from 13:00h CE(S)T until 18:00h CE(S)T.
