High-end NAS products may support Gigabit Ethernet (GigE) for even faster data transfer across the network. The two-controller NAS system expands capacity with the addition of drive shelves, depending on the scalability of the controllers. Scattered storage arrangements will not work for SMBs. A late development in NAS circles is special kinds of support for streaming 4K video, and the spec sheet is your friend in these cases. With scale-out NAS, the storage administrator installs larger heads and more hard disks to boost storage capacity.
Each of these issues contributes to lack of efficiency and potential loss of income if customers must wait for a data outage to be corrected. These drives will allow NAS makers to fit more drives into their chassis, which means more long-term storage capacity. Enterprise NAS provides rapid access and NAS clustering capabilities. SoftNAS Cloud NAS software-only product enables customers to scale data migration to Amazon Web Services (AWS), Microsoft Azure and VMware vSphere. Keep an eye on your inbox! Our expert industry analysis and practical solutions help you make better buying decisions and get more from technology. Western Digital Corp.

This consolidates block- and file-based data on one storage array. Network-attached storage (NAS) is a file-level (as opposed to block-level storage) computer data storage server connected to a computer network providing data access to a heterogeneous group of clients. Homeowners may rely on NAS to manage storage for smart TVs, security systems and other consumer-based internet of things (IoT) components. Instead, all the objects are presented in a flat address space. Sign-up now. You could also use your NAS to make your files available to you over the Internet , using it as a remote file server you can access from anywhere. Although it may technically be possible to run other software on a NAS unit, it is usually not designed to be a general-purpose server. Hyper-converged infrastructure (HCI) bundles the computing, network, SDS and virtualization resources on a single appliance. NetApp Inc. helped pioneer the use of an extensible file system with its Fabric-Attached Storage (FAS) and, more recently, All Flash FAS. NAS is like having a private cloud in the office. With plenty of room for photos, videos, music and files, the EX4100 helps protect your content with multiple RAID options all the way from RAID 0 to RAID 10.
