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 ObjectivesDetermine 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

Continuous data availability. Use when:

Response time impact is acceptable

Within metro distance

No data loss is the objective

Fastest recovery time is required

ASYNCHRONOUS Remote CopyExtended distance disaster recovery. Use

when:

Smallest response time impact to applications is required

Extended distance disaster recovery is the objective

Minimal data loss is acceptable



. . . with enormous impact on the business

Downtime costs can equal up to 16 percent of revenue 1

4 hours of downtime severely damaging for 32 percent of organizations, 2

Data is growing at explosive rates – growing from 161EB in 2007 to 988EB in 20103

Some industries fine for downtime and inability to meet regulatory compliance

Downtime ranges from 300–1,200 hours per year, depending on industry1

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

System z $32.1M Storage $45.3M Software $3.6M GDPS $2.3M

Total IBM revenue: $83.2M

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.

GDPS at Fedex

System z HW and SW $7.0M Storage $6.9M GDPS $900K

Total IBM revenue: $14,8M

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.

GDPS services opportunities can starburst—to include related hardware and software at time of sale, and follow-on hardware and services revenue

ValueVision

Experience

”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

configuration took 21-33 seconds without application outage. The user impact time of unplanned disk reconfigurations was 9-16 seconds; with 8 seconds to swap a configuration of over 4,600 PPRC

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."

Wolfgang Dungl, Manager of Availability, Capacity and Performance ManagementWolfgang Schott, GDPS Project Manager iT-AUSTRIA



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).
