  • Delivers consistent cache preservation with purpose-built battery for System Memory cache
  • Supports uninterrupted data availability via factory-new IBM cache battery for DS3000

Purpose-Built Cache Protection

The IBM 39R6519 is a dedicated cache battery engineered for the DS3000 System Memory subsystem. It supplies the reserve power that preserves cached write data during unexpected power interruptions. Storage administrators responsible for DS3000 arrays use this module to maintain data integrity across power events.

Direct Replacement Module

This battery installs directly into the designated cache slot without additional cabling or configuration software. The form factor matches the original specification, so the controller recognises it immediately and resumes normal cache-flush operations. No firmware updates or driver packages are bundled; the hardware alone restores the intended protection layer.

DS3000 Cache Compatibility

The sole qualification for this part is confirmed compatibility with the DS3000 System Memory cache. It does not fit other storage controllers, server platforms or external cache enclosures. Verify the subsystem model before ordering; an incorrect match will leave the cache unprotected.

Questions about this item

How often does the DS3000 System Memory cache battery need replacement?

The IBM 39R6519 cache battery is a consumable component; replacement timing depends on DS3000 system usage patterns and write-cache activity.

What limits the battery runtime during continuous cache operation?

Runtime is determined by the DS3000 System Memory cache power draw and the battery cell capacity designed for the 39R6519 module.

Does the 39R6519 generate noticeable heat or noise inside the DS3000 enclosure?

As a solid-state battery module it has no moving parts and produces no audible noise; heat output is minimal during normal cache-backup duty.
