FlashSystem for IBM i: What Attaches Where

Updated August 13, 2026

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.
