Attachment 10b.8 – E032 R112 Shelter – Server Stack – 02-FMECA.xlsx

This document contains a preliminary failure modes and effects criticality analysis (FMECA) for server stacks on a shelter.

The FMECA analyzes potential failure modes for two redundant server components, labeled E031-RS-112 Server-01 and E032-RS-112 Server-02. It identifies 42 possible failure modes including improper or loss of data, improper operation due to timing problems, open or short circuits, internal failures, and poor air flow from fans. Each failure mode is assigned a criticality value based on its potential effects on the server, higher-level systems, and the overall shelter mission. Taking the redundancy of the server stacks into account, the document modifies the criticality classifications from categories I-III to the lower category III-1R. The FMECA will inform further analysis and design to improve reliability of the critical server components.

The related federal contract opportunity is a draft request for proposal for low-rate initial production and full-rate production of the Integrated Battle Command System hardware. It involves producing IBCS end items according to technical data packages and specifications while maintaining approved software/firmware and authority to operate on existing hardware. Engineering changes may be required for obsolescence, new capabilities or export. The solicitation number is provided as well as description of the agency, Department of the Army Materiel Command Contracting Command at Redstone Arsenal.
