FlashSystem 5600, 7600, and 9600: Which Current IBM Array Fits?
IBM's current FlashSystem decision starts with three main performance tiers: 5600, 7600, and 9600. All three belong in the same family, but the right model depends on workload density, host count, capacity growth, replication, and refresh path.
Current model fit
| Model | Best Starting Question | Typical Fit |
|---|---|---|
| FlashSystem 5600 | Do we need compact low-latency storage? | Smaller mixed workloads, compact OLTP, branch, edge, and IBM i environments. |
| FlashSystem 7600 | Have we outgrown entry storage? | Larger mixed workloads, virtualized estates, 7300-class refreshes, and broader host attachment. |
| FlashSystem 9600 | Are we consolidating critical workloads at scale? | Flagship workloads, high bandwidth, 9500-class refreshes, and large protected-capacity designs. |
Do not pick the model only by effective capacity. Confirm latency target, host paths, snapshots, replication, Cyber Vault, support term, and future expansion.
