Versity enables organizations to use a single standard file system interface to archive large data collections at the lowest possible cost. With performance that will saturate the hardware, a scalable namespace that can handle up to one trillion files, excellent and highly accessible support, and friendly business practices, this is an archiving system you can love!
Versity Storage Manager (VSM) is a comprehensive software platform that automates the process of storing and retrieving archival data. VSM creates copies and writes them to ultra low cost mass storage media and services including tape, disk, optical, on premise object storage, and public cloud storage. Data is moved from primary storage systems such as Pure, NetApp, GPFS, & Lustre, to VSM where it is packaged efficiently, and then automatically archived to long term storage media according to a defined set of policies. The archive software features a standard POSIX file interface and is compatible with both NFS and SMB so it is easy for Mac, Linux, Windows, Globus, web clients, or any POSIX compliant application or tool to seamlessly access archived data. The VSM product is comprised of two main components: the Intelligent Cache™, and the Archive Engine™. Together these components efficiently package and group incoming data, and then send copies to the specified archival media according to rich policies which are configured by the administrator.
Files are containerized in the open source GNU tar format for long term access. Incoming files are grouped intelligently by user, group, media type, file type, path, or size. Groups are then optimized by size, destination, media target, and number of copies. Individual files or objects may be read back from within groups and from within tar containers without retrieving the entire group. Optimal grouping allows VSM to stream data to archival storage devices and services at high throughput levels, often exceeding 10 GB/s per server.
VSM is capable of ingesting and archiving both files and objects. Modern archiving workloads often include a mix of file and object data. VSM supports both without any modification of enterprise applications and without any reliance upon third party object to tape appliances which limit performance, functionality, and utilization. Protecting object data on tape is easy with VSM.
VSM metadata is stored in the filesystem on SSD's and remains online for responsive search, browsing, and access by enterprise applications. Only file data is moved to slower archival storage tiers. With no external database or out of band metadata storage there is never any possibility of synchronization errors.
With VSM, you never need to worry about running out of cache space! Cache space is managed between high and low thresholds set by the administrator. Archived files are intelligently released (removed) from the cache as needed. Release priorities are configurable for optimal performance (size, itime, rtime, mtime).
When a file is deleted from the archive the space on archival media is automatically reclaimed periodically by a process called recycling. Once an administratively configurable amount of space becomes available on a given piece of media, the recycler automatically recovers the unused space in a background operation.
The Versity Archive Fabric ModuleTM, which is included with VSM, analyzes any file system and provides an analysis that is useful for determining what data is a strong candidate for archiving, and moves the data to the VSM cache.
If your organization is facing end of life for OHSM or your Solaris infrastructure, you can move to a more friendly HSM vendor and easily switch from SAM-QFS or OHSM. VSM can restore SAM-QFS or OHSM dump files and immediately begin reading and writing data on existing tape or disk systems. That's right, you can adopt a better solution with no data migration.
