Answer
Yes. An IBM i partition connects to a FlashSystem array through the same external SAN attachment path used for other external storage, provided the Power server has supported host adapters and the FlashSystem array is configured for IBM i attachment specifically. This is a common path once internal DASD capacity or performance is exhausted, or when a business wants to consolidate IBM i storage onto shared infrastructure serving other platforms.
Buyers evaluating this path should confirm adapter and firmware compatibility with the exact Power server generation before ordering FlashSystem hardware or FlashCore Module capacity.
