Quantum StorNext 5 is a file-based management and archive solution comprised of two components, the StorNext File System and the StorNext Storage Manager. This product provides a scalable, policy- based, multi-platform file tiering and archiving solution. It has established a significant installed base in the Media and Entertainment industry and other industries that typically handle large numbers of large files. Quantum has built an extensive line of storage platforms to use with StorNext, including disk-based appliances, object storage systems and tape libraries. For the Open Storage Platform we will focus on the StorNext File System component, a SAN file system that is available as a software-only solution. For more information on StorNext 5, see Evaluator Group Archive research.
StorNext v4.7 is the latest version of the StorNext File System (SNFS) software. It runs natively on a Windows or Linux host, called the Metadata Controller (MDC), laying a scalable file system over any storage volumes that are allocated to it. These are traditionally fibre channel- or InfiniBand- connected storage arrays, object storage systems or tape libraries on the back end. In an OSP system the MDCs (usually redundant) would be run on x86-based servers in a scale-up configuration.
The primary storage capacity presented to the SNFS would typically be resident in the MDC servers with internal or direct-attached storage devices. Additional capacity could come from SAN-attached storage, the same way a ‘traditional’ StorNext implementation would look. These could be block storage arrays or object storage systems. Tape libraries could be included with the StorNext Storage Manager software, which can run on the same MDCs.
On the front end, the Metadata Controllers can serve files to SAN-based host systems through a StorNext agent running on Windows, Linux, UNIX or Mac OS X. SNFS can provide parallel or concurrent access to files for multiple SAN-based hosts, improving performance in the large file environments the product was designed for. LAN-based clients can access files via CIFS or NFS through a Distributed LAN Client (DLC) Gateway, running on a dedicated server, or on the same hardware as the Metadata Server. SNFS clients can also be VMs on SAN- or LAN-attached hosts.
