The mainframe storage environment supporting the three mainframes in the WCS Tier 3 Co-location must be comprised of a homogeneous fabric to contain Tier1 Storage, Tier 2 storage and an object storage fabric.

The mainframe storage environment for the three mainframes located in the WCS Tier 3 Co-location must be built using a homogeneous fabric that integrates Tier 1 storage, Tier 2 storage, and an object storage fabric within a unified architecture. This requirement ensures consistency, compatibility, and streamlined management across all storage tiers supporting critical mainframe operations. The structure must be designed to meet the performance, reliability, and scalability demands of the Social Security Administration’s infrastructure without fragmentation or proprietary silos. The storage solution must be capable of supporting enterprise-level workloads and maintaining high availability for mission-critical systems hosted within the co-location facility.
