Continuous Availability (CA) / and Disaster Recovery
(DR) questions ?
Is Continuous Availability (CA) / and Disaster Recovery (DR) a current
business focus ?
What level in the organization is driving this? (Business or Technical)
Is your CA / DR solution driven by business competition?
Regulation/Litigation? Reputation and brand loyalty? Productivity?
What do you do for CA / DR today?
 What are your RPO and RTO objectives ?
 Do you currently subscribe to a DR off-site solution?
 Do you currently have multiple data centers today? How far apart ?
What will you do for CA / DR in 3-5 years ?
 What will be the RPO and RTO objectives ?
 Will you have multiple data centers today? How far apart ?

Customer Business Objectives
Determine business continuity objectives:
 Recovery Time Objective (RTO) –
How long can you afford to be without your systems?
 Recovery Point Objective (RPO) –
How much data can you afford to lose / recreate?
 Network Recovery Objective (NRO) –
How long to switch over the network?
Select technology(s) to meet business objectives
SYNCHRONOUS Remote Copy
ASYNCHRONOUS Remote Copy
Continuous data availability.
Use when:
Extended distance disaster recovery. Use
when:
 Response time impact is acceptable
 Smallest response time impact to
applications is required
 Within metro distance
 No data loss is the objective
 Fastest recovery time is required
6

Sales Lessons Learned
Important to have a knowledge of business processes and applications
A broader understanding of the company’s risk tolerance and maturity can
be very helpful in positioning our solution
GDPS can dramatically decrease the recovery times and points, while
increase service level availability
Storage and data are at the center of the discussion
SunGard, Accenture, HP and EMC represent IBM’s greatest competitive
threat in the Business Continuity marketplace
When IBM leverages all of its strengths, we are clearly the leader!

Revenue and Profit Potential Across IBM Brands
GDPS at Wells Fargo
GDPS at Fedex
Wells Fargo is in the process of implementing a 3-site
GDPS configuration (MzGM) – a combination of
GDPS/PPRC and GDPS/XRC. Scheduled to be
completed in December of 2009, it will be the worlds
largest GDPS configuration with a substantial zLinux
infrastructure supported by the GDPS xDR Feature.
Federal Express has implemented GDPS/PPRC
HyperSwap Manager for continuous availability of data
and GDPS/XRC for extended distance protection and
automated failover in case of a disaster. Fedex also
replaced EMC autoswap with IBM’s GDPS HyperSwap
Manger.

”Using the GDPS/PPRC HyperSwap technology is a significant step forward in achieving continuous
availability. The benefits in our GDPS environments are that planned switches of the disk
 (new) GDPS
configuration
took 21-33 seconds without application outage. The user impact time of unplanned
qualification program
disk reconfigurations was 9-16 seconds; with 8 seconds to swap a configuration of over 4,600 PPRC
(IBM and Hitachi)
volume pairs. Without HyperSwap planned and unplanned reconfigurations had resulted into a
service outage of almost two hours in our Sysplex/GDPS with 10 systems."

Learning Points High Availability - GDPS
1. GDPS is a Continuous Availability (CA) and Disaster Recovery (DR)
Solution.
2. Recovery Time Objective (RTO) – Time to get all applications up and
running (after disaster).
3. Recovery Point Objective (RPO) – If data recovery backleveled the
data, how long? (what is the time currency of the data after recovery).
4. Metro Mirror is a Synchronous Disk replication technique limited to
distances less than 100K. (Example: GDPS/PPRC)
5. Global Mirror is an Asynchronous Disk replication technique across
unlimited distances. (Examples: DPS/Global Mirror and GDPS/XRC)
6. Hyperswap provides CA within a data center via GDPS/PPRC – this
protects from a Storage Control Failure with a RPO of 0 and an RTO of
less than 1 hr (typically far less).
