Network attached storage (NAS) devices are designed to create easily expandable and secure data storage devices. They usually feature multiple drives, RAID protection options and hot-swap capabilities for reducing down time should drive failure occur. Software-powered features vary depending on the operating system included, and the processor and memory onboard, but may include automated backups, remote access, VPN, encryption, snapshots and advanced RAID configurations. Rackmount units may also feature multiple network ports, up to 10Gb/s connectivity, redundant power supplies and the ability to connect additional disk shelves to expand capacity.
These NAS accessories allow you to expand or upgrade your NAS solution with features like extra memory, enhanced networking or additionally connectivity.
