MMFR Sole Justification for PSSC Labs Compute Cluster Nodes_CO_S_20260801_Redacted.pdf

This is a Memorandum for Record documenting a sole source justification for a federal procurement by the Department of the Air Force, United States Space Force, Space Launch Delta 30.

The Air Force seeks to procure compute cluster nodes through PSSC Labs (GSA schedule GS-35F-0598R) to expand computational capacity for pre-launch and Day of Launch risk analysis, and to enable mission content analysis in support of launch operations. The required computing solution comprises 768 total AMD EPYC 2.0 GHz processor cores, 1,536 hyperthreaded cores, 4,096 GB of high-performance ECC system memory, 7.0 TB of RAW storage space, and 480 GB raw storage per compute node. The system includes a 10/100/1000/10000 10 GigE high-performance network backbone, existing 48-port 10 GigE network switch, 48-port 10/100/1000 Gigabit Ethernet switch, remote management and monitoring network, rack and power infrastructure utilizing existing 42U rack enclosures and dual 208V/30 AMP power distribution units. The solution must include CBeST Cluster Management Toolkit v6.0, Red Hat Linux 9.x operating system with one-year subscription license, TPM 2.0 security, ARCTOS RRAT compatibility, TAA-compliant USA-built components, and a three-year complete warranty. PSSC Labs services bundle and support are included. The sole source justification is based on the requirement that the computing solution must be specifically designed for ARCTOS application software and maintain strict compatibility with existing PSSC Labs-manufactured onsite infrastructure; PSSC Labs is identified as the only vendor capable of meeting these highly specialized compatibility requirements. The contracting officer certification confirms the anticipated cost is fair and reasonable.
