The move is aimed at improving their joint offerings in data protection, storage management, and information security.
The companies plan to combine Fujitsu's Eternus storage systems and Primergy servers with Symantec's data and storage management software products.
These include NetBackup, Backup Exec, Backup Exec System Recovery and Storage Foundation, and Symantec Endpoint Protection.
Both companies will integrate their products and services to help customers streamline datacentre, information and risk management, as well as reduce costs.
Greg Hughes, enterprise products group president of Symantec, said customers continued to face flat or decreasing budgets in light of exponential information growth.
"With this enhanced relationship, Fujitsu and Symantec intend to more tightly integrate our solutions and services to help customers improve hardware utilisation, reduce complexity, and improve operational visibility," he said.
