Unplanned?

Disaster Recovery?All of the above?

High Availability (HA) or Continuous Availability(CA) requirements?

Near zero downtime for any outage type?

Loss of transactions not tolerated?

Availability level vs.. cost vs.. complexity

Complexity varies, but all solutions createsadditional complexity

Long distances between the primary and backupservers?

Communication costs

Availability discussions should include

1. Server hardware

2. Storage (disk and tape storage)

3. Software and Automation

4. Networking

5. Services

"Half" of an HA solution is service & support

Investigate customer reference accounts on both implementation and postimplementation service and support

If you are using or deploying a package like SAP, JDE, Intensia ...find out howmany they have done, how many are in production, talk to a referenceaccount on how the project went

Does the solution provider support ClusterProven ISV solutionsProject Plans (ask for a project plan documentation example)

Project Ownership, Project Manager, Implementation Plan

Test Plan, Training Plan,

What type of technical training certification is required for the implementation

experts in both the ISV solution and iSeriesPost Installation Support, how many support people per installed customer ?Training and certification

Assess Total solution attributes....

Positioning Availability Solutions

iSeries Clustering and High Availability Business Partner Solutions

Most widely deployed type of HA solution across iSeries install base

Can be the most resilient and diverse coverage model

Ask reference accounts about service and support

Single server and Save-While-Active (SWA) for backups

For disaster recovery

iSeries Replication Clusters (internal or ESS storage) OS/400 Mirrored ESS

Hosted iSeries Services or Business Continuity Recovery Services

For basic planned and unplanned outages

iSeries Switched Disk Clusters

Best solution will often be a combination of one or more availability technologies

Analyze your availability requirements first Engage your iSeries rep or HA expert for assistance
