FlashSystem for IBM i: What Attaches Where
An IBM i FlashSystem decision is an architecture decision. The storage array, Fibre Channel fabric, Power host adapters, VIOS layout, multipath design, and recovery plan all need to match.
Internal vs SAN
Internal NVMe solves local server storage. FlashSystem solves shared external block storage with array services.
Pathing
Confirm zoning, host ports, preferred paths, failover behavior, and maintenance paths before cutover.
IBM i recovery
Align FlashSystem copies and replication with IBM i save, journal, application, and restart procedures.
For the decision checklist, see FlashSystem for IBM i and IBM Power.
