EFSaaS is a private Enterprise File Synchronization and Sharing (EFSS) solution for Enterprises and SMBs. It helps users easily build their own EFSS services, which includes countless cloud-based benefits such as anytime, anywhere data access, FTP replacement for file sharing, team collaboration tools and email attachment integration. EFSaaS can be implemented on various hardware platforms, including on a 3U-16 bay Intel x86 server-storage appliance which is suitable to be deployed by SMBs. In addition, if performance demands it, EFSaaS can be implemented on multiple Intel x86 1U servers connected to both SAN and NAS. This solution provides the redundancy to protect both servers and storage.
