IBM FlashSystem 7300
High-interest midrange FlashSystem model for buyers comparing 7300-class replacements, Hitachi VSP One Block, Dell PowerStore, Pure Storage, and the current 7600 tier.
FlashSystem 7300 is where many comparison questions cluster. The useful page is not a spec repeat. It is a decision map for whether a buyer should keep, expand, refresh to 7600, or compare against Pure, Dell PowerStore, and Hitachi VSP One Block.
A 7300 vs competitor question needs workload and recovery context first. Ask about host mix, ingest behavior, usable capacity, replication, protected copies, and lifecycle commitments before comparing array families.
IBM accelerated the FlashSystem 7300's withdrawal from marketing from June 30, 2026 to May 16, 2026, with a final order cutoff of May 15, 2026, citing parts availability and supply chain pressure. New 7300 orders are no longer possible; treat any remaining 7300 as installed-base support or refresh-to-7600 planning.
IBM FlashSystem 7300 datasheet reference
The 4657-924 control enclosure runs FlashCore Module 4 media (FCM3 on earlier orders) across the standard 4.8 TB, 9.6 TB, 19.2 TB, and 38.4 TB FCM4 capacity ladder. A 7300 price request should specify which capacity point and how many modules, since a 19.2 TB FlashCore Module 4 quote and a 38.4 TB FlashCore Module 4 quote are not comparable line items.
