Draft RFP - Enterprise Service Solutions IV

The Defense Information Systems Agency (DISA) is seeking industry feedback on a draft Request for Proposal (RFP) for Enterprise Service Solutions IV (ESS IV), an Indefinite Delivery/Indefinite Quantity (IDIQ) contract to provide managed storage services and on-demand storage solutions for approved locations within and outside the continental United States. The primary objective is to obtain a scalable, flexible storage system that can dynamically adapt to varying storage and throughput demands through a utility-based billing model based on actual usage. The contract will encompass comprehensive managed services including hardware, software, licensing, design services, logistics, field maintenance, and systems engineering services to support all application workloads. Evaluation will be conducted through a multi-phase process including written proposals, oral presentations, and potential Proof of Concept demonstrations, with key evaluation factors including Small Business Participation Plan, Supply Chain Risk Management Plan, and Technical/Management Approach using a best value trade-off methodology. The deadline for submitting feedback on the draft RFP and Performance Work Statement is December 29, 2025, and the government will not accept actual proposals in response to this draft notice but will consider all submitted comments before finalizing and publishing the formal solicitation.

No set-aside designations have been applied to this procurement. The contract carries an estimated total value of approximately $500 million and will consist of a five-year base period with five one-year renewal options, providing a potential ten-year contract lifecycle. The solicitation includes mandatory minimum small business participation goals requiring 23 percent participation by small businesses, 5 percent by small disadvantaged businesses, 5 percent by women-owned small businesses, 3 percent by HUBZone businesses, and 5 percent by service-disabled veteran-owned small businesses. The sample task order provided details a multi-tenant infrastructure environment supporting 411 physical servers, 1,430 virtual servers, 6,010 terabytes of used storage, and a total front-end throughput of 80 gigabytes per second, which represents the scale and complexity of the storage solutions being sought. Additionally, DISA requires the prime contractor to sponsor at least two facility clearance levels for small businesses during the base contract year as part of its commitment to removing barriers to entry for small business participation.
