Abstract
Is it time to re-evaluate your Business Continuity and Disaster Recovery plans?
This session will cover the basic concepts, industry definitions and best practices
This session can apply to all environments, including System z mainframe, POWER Systems, and x86 servers.

Three Components of Business Continuity
Fault-tolerant, failure-resistant streamlined infrastructure
with affordable cost foundation
1. High AvailabilityNon-disruptive backups and
system maintenance coupled with continuous availability of
applications
2. Continuous OperationsProtection against unplanned
outages such as disasters through reliable, predictable
recovery
3. Disaster Recovery
IT DataProtection

Some Fundamental Truths about Business Continuity
1. Disasters Happen.
2. A Disaster is any incident or event that interrupts access from decision-makers and applications to business data for whatever constitutes an unacceptable period of time.
3. A Disaster is usually distinguished from a mere inconvenience (temporary crisis) by its duration.
4. The nature of the business process impacted determine its tolerance for downtime, which is relative and contextual.

Business Continuity – Key Goals
1. Operations continue after a disaster
2. Recovery is Predictable and Reliable
3. Costs are Predictable and Manageable
4. Protection of Critical Business Data throughout the entire process

Planning Should Focus on Effects – Not CausesAll effects tend to fall into one of four categories
1. Workforce shortage caused by infectious outbreak, labor strike, extreme weather or a breakdown in transportation
2. Loss of technology due to cyber attack, interruption in communications, power outage or flood
3. Loss of facilities resulting from fire, workplace violence, hurricanes, floods and other natural disasters
4. Failure in the supply chain that prevents the shipping and receiving of products and raw materials

App 1 App 2 A3 A4 A5

Business Continuity Plans (BCP) should focus on “Business Process” as unit of recovery
• Prioritize Gold, Silver, Bronze• Decide RTO for each, for example:
• Gold in 4 hours• Silver in 48 hours• Bronze 2 weeks or longer
• Be pragmatic
Determine which Applications and Data are required to support each Business Process
• IBM Tivoli Application Dependency Discovery Manager (TADDM)
Identify server, storage and network infrastructure needed to support the Applications and Data
• Can these run in the Cloud?

•The primary site initiates an I/O to the secondary site to transfer the data
•Secondary indicates to the primary that the write is complete
•Primary acknowledges to the host application that the write is complete
•Round-trip latency added to each Write I/O
• 1 msec delay per 100km separation distance

• A mirror or backup copy is only useful if all data for an application is saved at a consistent point
• To achieve snapshot consistency, Long Busy is used to create point in time copy on multiple volumes at a single point in time
• To achieve consistency at a remote mirror location, the order of dependent writes must be maintained and a dependent write to a volume must be mirrored if other dependent writes were successfully mirrored
• The remote mirror functions each maintain consistency in their own way

� Simplify and automate complex replication tasks – Automated replication configuration scales up to thousands
of pairs of disk volumes– Preserves historic configuration information
• easy setup for repetitive configuration or re-configuration– Operational control of replication environment via a highly
usable GUI rather than DSCLI scripts or TSO commands• but provides also CLI, csmcli

�Support for heterogeneous guest OSs
– AIX– Red Hat, SUSE, and Ubuntu Linux– IBM i
� Automated Disaster Recovery management
� Economics of eliminating hardware and software resources on backup site
– Enterprise Pool support (optional)
� Easier deployment for DR: unlike clustering or middleware replication technologies
� VM restart technology has no OS or middleware dependencies
A simplified way to manage DR
�Enterprise Pool support: DR site for less�Storage replication: EMC, SVC/Storwize.

Information concerning non-IBM products was obtained from a supplier of these products, published announcement material, or other publicly available sources and does not constitute an endorsement of such products by IBM. Sources for non-IBM list prices and performance numbers are taken from publicly available information, including vendor announcements and vendor worldwide homepages.

The information is presented here to communicate IBM's current investment and development activities as a good faith effort to help with our customers' future planning.
Performance is based on measurements and projections using standard IBM benchmarks in a controlled environment. The actual throughput or performance that any user will experience will vary depending upon considerations such as the amount of multiprogramming in the user's job stream, the I/O configuration, the storage configuration, and the workload processed. Therefore, no assurance can be given that an individual user will achieve throughput or performance improvements equivalent to the ratios stated here.
