NAS (Network Attached Storage) signifies standards-based file access via CIFS/FTP protocols. Client workstations gain access by simply plugging into the IP network. No software installation or special hardware is necessary on client workstations, significantly reducing deployment and management complexity.
SeaChange’s patented symmetrical, distributed file system technology distributes file system and RAID (“raid squared”) processing evenly across all the nodes in a MediaLibrary cluster. Online addition of new cluster nodes allows MediaLibrary to take on more client connections with more processing horsepower. Users can also scale storage capacity independently from bandwidth by adding cost effective storage expansions without service disruption.
SeaChange’s patented RAID technology extends the traditional RAID (Redundant Array of Inexpensive Disks) from a single computer to an interconnected network of computers (also known as RAIN – Redundant Array of Inexpensive Nodes). RAID protects data by generating and maintaining parity data, an overhead that represents 11% of the total storage capacity for a nine-node MediaLibrary. Compared to alternative mirroring technology, RAID alone brings 45% cost savings for MediaLibrary customers.
Simple to Manage:
SeaChange’s patented scalable NAS technology combines the traditional function of file system, volume management, and RAID into one intelligent virtualization layer. The MediaLibrary completely eliminates the antiquated notion of volumes (also known as LUNs) and the complexity of managing volumes. All storage resources are part of the single file system pool. Capacity planning becomes a simple matter of monitoring the utilization level of the file system. New cluster nodes and storage expansions are added online and seamlessly integrated into the pool.
