The Department of Veterans Affairs has awarded Peraton an IT infrastructure contract worth up to $497 million over seven years.
Peraton will provide infrastructure-as-a-managed service for storage and computing infrastructure facilities in the US and abroad, across the VA's roughly 300 sites.
The deal will see Peraton integrate on-premise infrastructure with the VA Enterprise Cloud, including the department's electronic health records service VistA Imaging.
The IaaMS service will support up to 220+ petabytes of VA's mission-critical data, and enable VA to create a standardized service delivery model, the department said.
"Peraton is uniquely positioned to deliver next-generation storage capability and services to the VA and the veterans who have proudly served our country," said George Rollins, VP of VA and Defense Health, Peraton.
"This is an incredible win for the team. We look forward to our continued partnership with the VA, and to helping the Department realize the expected benefits from its major modernization initiatives."
Rival ThunderCat Technology previously protested the award of the contract to Perspecta, which was acquired by Peraton for $7.1bn, but has since withdrawn its complaint.
Built out of the IT unit of military contractor Harris Corp, and owned by Veritas Capital, Peraton also spent $3.4bn acquiring federal IT and mission support business of Northrop Grumman.
In February, Veritas separately jointly acquired defense IT contractor Cubic Corporation for $2.8 billion.
Peraton was also recently awarded a five-year contract worth $130 million from the DoD's Defense Manpower Data Center (DMDC). The company will support DMDC's effort to modernize more than 100 applications.
