IBM FlashSystem 5300
High-interest 1U NVMe FlashSystem still generating warehouse exposure, especially around 20 TB to 30 TB environments, datasheets, control enclosures, and refresh questions.
The 5300 is not only a legacy model page topic. It is where buyers ask whether a compact FlashSystem is enough, whether published reseller configurations still make sense, and whether a new quote should move to the 5600.
Use the 5300 page as a bridge between existing exposure and current 5600 decision paths. See the full generation table at IBM FlashCore Module Generations for exact FCM4 compatibility.
IBM accelerated the FlashSystem 5300'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 5300 orders are no longer possible; treat any remaining 5300 as installed-base support or refresh-to-5600 planning.
IBM FlashSystem 5300 datasheet reference
The 4662-7H2 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 5300 price request should specify which capacity point and how many modules, since a 9.6 TB FlashCore Module 4 quote and a 38.4 TB FlashCore Module 4 quote are not comparable line items.

Frequently Asked
Is IBM FlashSystem 5300 still relevant?
Yes, for installed-base, reseller-inventory, datasheet, and refresh research. The AS400/Midland warehouse shows FlashSystem 5300 as the strongest model-specific FlashSystem query. For a new current-generation quote, compare the 5300 question against FlashSystem 5600.
