The intelligent chassis of the Linksys Network Storage System NSS4000 gives administrators and integrators the flexibility to optimize the NSS for performance, capacity and a company's storage and sharing needs. The NSS4000 supports up to 15 concurrent, connected CIFS (Windows, Macintosh, Linux) users. Linksys NSS products bring robust NAS (Network Attached Storage) within reach of today's budget-minded workgroups and small businesses. They are ideal for storing, backing up, sharing and archiving critical information. The feature set of the NSS series set it apart from entry-level, desktop NAS systems, while at the same time its competitive pricing gives small businesses the opportunity to realize substantial cost savings when compared with more expensive storage systems. Unlike other NAS systems, that need to contain operating system software on one or more hard drives in a NAS system, each Linksys NSS product features a unique and intelligent chassis that contains the Linux OS that controls it. This gives the NSS system added stability and reliability, as well as the flexibility to be configured without connected drives or reconfigured at any time - even hot swapping and resorting hard drives to different storage bays. This flexible architecture makes the Linksys Business Series NSS series ideally suited for budget-conscious companies that are constantly growing and evolving.
