Usability: Speak to a customer reference that has role swapped during an unplanned outage

Reference accounts: what are they doing, how did they implement, how are they using it

Strategic development relationship with IBM

Industry solution provider relationships

IBM eServer iSeries


"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
