Product Overview

The intelligent Cisco NSS6000 4-Bay Advanced Gigabit Storage System Chassis (Figure 1) gives administrators and integrators the flexibility to optimize the network storage system (NSS) for performance, capacity, and the company's storage and sharing needs. The NSS6000 supports up to 132 concurrent, connected Common Internet File Systems (CIFS) (Windows, Macintosh, Linux) users. The Cisco Small Business Network Storage Systems bring robust network attached storage (NAS) 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 these network storage systems (Figure 2) sets them apart from entry-level, desktop NAS systems, while at the same time their competitive pricing gives small businesses the opportunity to realize substantial cost savings when compared with more expensive storage systems.
Unlike other NAS systems, which need to contain operating system software on one or more hard drives, the Cisco Small Business Network Storage Systems feature a unique and intelligent chassis containing the Linux operating system that controls it. This gives the storage 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 re-sorting hard drives to different storage bays. This flexible architecture makes the Cisco Small Business Network Storage Systems ideally suited for budget-conscious companies that are constantly growing and evolving.

Figure 2. Features of the Cisco NSS4000 and Cisco NSS6000 Network Storage Systems


• Advanced Gigabit network system chassis with support for Redundant Array of Independent Disks (RAID) 0/1/5/10 and "just a bunch of disks" (JBOD)

• Supports Mac/PC (CIFS), Linux (network fiile server [NFS]), and FTP clients

• File-based disk encryption (Advanced Encryption Standard [AES] 256)

• Virtualization/aggregation master unit (Allows RAID sets to span chassis)

• Advanced storage network features - Self-Monitoring, Analysis, and Reporting Technology (SMART), journaled file system, and diskless design

• Optional redundant power supply support via the Cisco RPS1000 380W Redundant Power Supply Unit
