Internal DASD Expansion

Power Systems Internal DASD Expansion Drawer

An internal disk expansion drawer adding DASD capacity directly to an existing Power server without introducing external SAN complexity.

Storage Systems

Program Overview

Internal DASD expansion is usually the simpler path when a shop just needs more disk pool capacity and is not trying to consolidate storage across platforms. This drawer adds supported drive bays without the added complexity of external SAN fabric and multipathing.

Sizing should be driven by actual ASP disk busy and free space trends, not just how many empty bays remain in the current enclosure.

Best Fit

Best fit for shops that need more disk pool capacity on an existing server and want to avoid the added complexity of external SAN attachment.

What this program helps with

  • Supported drive bay expansion for the target Power server enclosure
  • Mixed drive type support where the platform allows it
  • Straightforward addition to existing ASP configuration
  • Lower implementation complexity than external SAN attachment

What to vet before shortlist

  • Confirm enclosure and backplane compatibility with the exact server model
  • Check current RAID or mirroring protection before adding new drives
  • Review disk busy trends to size capacity rather than just replacing free space
