Frequently Asked Questions

Can 01EK172 and 01EK157 modules coexist in the same FlashSystem array?

Yes — IBM qualifies all three 3.61TB MicroLatency module variants as interchangeable within the same FlashSystem array. Mixing IBM-approved variants is fully supported.

Is the 01EK172 a newer revision than the 01EK157?

IBM part number suffixes reflect IBM's internal qualification and supply chain designations rather than strict generational ordering. Both modules deliver identical MicroLatency performance specifications for supported FlashSystem platforms.

How many MicroLatency modules can a FlashSystem enclosure hold?

Module capacity varies by FlashSystem model. IBM FlashSystem 900 supports up to 12 Small Flash Modules per enclosure. Consult the IBM FlashSystem product guide for your specific model's maximum module count and total raw capacity.

The IBM 01EK172 ensures uninterrupted supply of 3.61TB MicroLatency flash capacity for IBM FlashSystem environments — delivering the same deterministic sub-100µs performance and FlashCore compression as the broader 01EK family while giving storage procurement teams a reliable alternative sourcing option.
