• Moving of our mainframe LPARS to a shared mainframe environment, achieving
‘economies of scale’ on Mainframe infrastructure costs for hardware and software.
• Triggers:
• Work on Cost Program
• New required investments: DASD subsystem needed to be replaced
• Process
• 12/2013 Start study outsourcing Mainframe environment
• 01/2014-06/2014 RFI/RFP process
• 07/2014 Selection provider
• 08/2014-11/2014 Contract negotiations with NRB
• 12/2014-05/2015 Migration project

6. 6
3. Why NRB?
Evaluation criteria ( evaluation matrix – objective decision)
• Price
• Other criteria:
• Quality RFP proces - contacts
• Location ( team on one location or separated, West-Europe … )
• Quality transformation and transition during migration phase
• Flexibility concerning ITIL processes ( change requests, problem solving )
• Current infrastructure
• Flexibility SW versioning
• DRP solution
• Availability and performance
• Security base line assessment
• Network: latency
• Optional: additional savings

7. 7
4. Project goals
• Moving of our mainframe LPARS to a shared mainframe environment at NRB, achieving
‘economies of scale’ on Mainframe infrastructure costs for hardware and software
• Ability in a later stage for additional savings related to ISV (Independent Software
Vendors) : contract merge, SW replacement.
• Infrastructure As A Service (IaaS cloud model)
Only hosting hardware – all system engineering activities remains @ SD Worx
• Integration of change management, incident management and DR processes between SD
Worx and NRB for Iaas related activities.
• Ensuring the transparency for business with at least the same performance, availability
and with state of the art technology - at a lower cost.

5. Project tracks
• Technical
• Transformation tracks
• Cut-over actions
Both for:
• Distributed servers (latency sensitive applications)
• Mainframe
• Network
• Services and procedures
• Testing

9. 9
6. Technical track : transformation
5 important technical tracks to be executed before testing & migration :
• Distributed applications: move latency sensitive applications to separated servers
• TCPIP change track : Change IP addresses of all lpars to avoid IP and network changes
during cut-over weekend(s)  Reduce risk and complexity
• GENERAL ‘MF infrastructure preparation’ track: create a ‘landing platform’ for all the
SDWORX lpars  Make sure all basic infrastructure is in place and corresponds to the
SDWORX needs
•
DISK migration track : Setting up an asynchronous replication mechanism between the
secondary SDWORX MF disk subsystem and the new primary disk infra at NRB allowing
smooth testing and ‘fast’ cut-over.
• TAPE Migration track : Convert tape data from CA-VTAPE to hardware VTS solution and
allow tape data to be migrated ‘in advance’ to NRB using VTS GRID functionality.

10. 10
6. Technical track : MF hardware
CPU (existing zEC12-505 CPU – 347 MSU)
• Target : zEC12-614 (4 Shared CP’s + 2 ‘Dedicated’ zIIPs)
• ‘absolute capping’ to limit peak CPU behavior
DISK (existing DS8830)
• Target : DS8870 with flash storage modules and EASY TIER (production environments)
( I/O RT improvement )
TAPE (existing CA VTAPE software virtual tape solution)
• Target : IBM TS7720 virtual tape solution - ONLY on disk.
( tape access time improvement)
CONNECTIVITY
• LAN (4x 1 GbE ports available - 2 ‘isolated’ for preprod & 2 for other partitions –
active/passive)
(to-be equal to as-is situation)

11. 11
7. Services and procedures
• Integration of change and incident/problem management procedures SD  NRB
• Operational Guide
• SLA’s :
• Availability
• Incidents
• Change requests (CPU , Disk , Tape capacity ) – emergency
• IT Continuity
• Performance
• Netwerk latency
• Disk PPRC
• CEC capacity (SYSP and SYSG lpars can peak at least 20% above their
defined capacity , the other lpars can peak at least 15% above their
defined capacities)
• Dummy applications (I/O, CPU)

8. Testing: formal process
• Testcoördinator
• Formal acceptance criteria ( part of contract)
• Detailed testscenario’s

9. Project evaluation
+
• Cooperation with NRB very professional and positive - both PM and technical staff
• Planning was respected during whole project.
• Staged migration whereby lessons learned were included in subsequent phases with an
error free migration of the production Lpars
• All IT departments the same focus/prio to this project: has led to internal smooth
cooperation between the various units and teams
-
• ISV contracts: some outsourcing fees to be payed
