FlashSystem Decision Areas
Open a focused decision profile here, or move directly to the full sizing, migration, comparison, resilience, recovery, and lifecycle guides below.
The directory keeps profiles that work as distinct reference records. Broader questions now belong to one full guide each, so the same subject is not split between a thin profile and a complete answer.
Size usable and protected capacity
Separate raw, usable, protected, replicated, growth, and effective capacity before comparing models.
Plan a Storwize migration
Map hosts, copy services, cutover, and rollback from V3700, V5000, V7000, or older FlashSystem arrays.
Compare storage families
Compare FlashSystem with Pure Storage, Dell PowerStore, and Hitachi around the real workload and recovery design.
Build cyber resilience
Connect detection, Safeguarded Copy, Cyber Vault, separation of duties, and tested clean recovery.
Design HA and DR
Define failure modes, recovery point and time targets, replication, site design, and restore testing.
Review Storage Assurance
Compare upgrade, support, migration, price protection, and capacity commitments across the lifecycle.
FlashCore Module (FCM)
The FlashCore Module decision: when IBM's FCM media matters for density, data reduction, telemetry, ransomware detection, and lifecycle planning versus standard NVMe media.
IBM i and IBM Power Attachment
Power and IBM i storage planning across Fibre Channel, VIOS, multipath, zoning, host adapters, internal NVMe, and SAN-attached FlashSystem design.
External Storage Virtualization
FlashSystem as a modernization platform through IBM Storage Virtualize, external array virtualization, migration services, and cross-system management.
