"Half" of an HA solution is service & support
Investigate customer reference accounts on both implementation and post implementation service and support
If you are using or deploying a package like SAP, JDE, Intensia ...find out how many they have done, how many are in production, talk to a reference account on how the project went
Does the solution provider support ClusterProven ISV solutions
Project 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 iSeries
Post 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
ƒ Most widely deployed type of HA solution across iSeries install base
ƒ Can be the most resilient and diverse coverage model
ƒ Ask reference accounts about service and support
Single server and Save-While-Active (SWA) for backups
For disaster recovery
ƒ iSeries Replication Clusters (internal or ESS storage)
ƒ OS/400 Mirrored ESS
ƒ Hosted iSeries Services or Business Continuity Recovery Services
For basic planned and unplanned outages
ƒ iSeries Switched Disk Clusters
ƒ Best solution will often be a combination of one or more availability technologies
Analyze your availability requirements first
ƒ Engage your iSeries rep or HA expert for assistance
