 Software Product  Description	HSManager - PRODUCT NAME:	HSManager for OpenVMS	SPD 50.00   	Hierarchical Storage Management    E HSManager provides "set and forget" management of space on active and I near-line storage. HSManager keeps active files on primary (fast) storage = and migrates little used files to secondary (slower) storage.   L HSManager supports magnetic disks,  compressing disks, ZIP archives, opticalF jukeboxes and tape autoloaders in any combination.  Disk and disk likeJ devices may be either primary or secondary storage, tapes and ZIP archives may only be secondary storage.  D HSManager integrates fully with all Acorn Software Products (Squash,K VirtualBranches and Branches) as well as with a variety of other rule based , storage managers available from 3rd parties.  I Using HSManager you make maximal use of your existing storage.  By moving C infrequently used data to lower cost storage you reduce your system A management expense, your system manager is not involved in manual K restructuring of your data, and your capital expense, by not needing to buy - additional, expensive, rotating mass storage.   G In addition, HSManager extends the OpenVMS file system to provide "soft L links" in two varieties.  Read/Only soft links allow data to be read, but ifI any attempt to write the data, data is moved to the original place before F the writing can occur.  Read/Write soft links allow data to be read orJ written wherever HSManager has placed it.  Soft links can span devices andJ are provided as a generic facility available independently of the specificI HSManager functionality (although HSManager has to be running in order to  utilize soft links).   BenefitsE Transparent migration of little or unused data to lower cost storage. C Fully integrated with compression software, tape data libraries and  magneto-optical data libraries.   Lowered system management costs. Reduced capital expenses.   Reduced requirements for backup.   Features) Compatible with all OpenVMS applications. I Transparent migration of data from primary to secondary storage and back. L Automatic, scheduled, and manual control in any combination over the managed data. C Built in space management algorithm based on dates, file sizes, and  available space.I Simple, menu driven, configuration of the storage hierarchy and the space  management. 9 Available for OpenVMS/VAX 5.5 and OpenVMS/AXP 6.1 and up.  "Soft links" that span devices.  Read/Only soft links.  Read/Write soft links. User defined storage hierarchy. H Supports a variety of 3rd party rule based storage management utilities.@ Optical Jukebox support for DEC, HP, IDE, Kodak, NKK and others.L Tape Autoloader support for Conner, DEC, DLI, Exabyte, Odetics, Spectralogic
 and others   Functional DescriptionL Using HSManager data files appear to be on a users disk while, in fact, theyH may have been anywhere, in a backup save set on a tape, some other disk,H etc. HSManager transparently (without user intervention) moves data fromL active to "inactive" storage in a process called shelving.  When the data isI accessed then that data is restored (as appropriate) to allow the user to ) access it in a process called unshelving.   G Depending upon the configuration, shelved data is always unshelved upon L access, unshelved upon write access only, or never unshelved, i.e., the data is accessed on the shelf.   P The user is never aware that his data is anywhere but where he expects it to be.E The system manager can specify a simple space management policy, then H implement that space policy manually or automatically.  In addition, theK system manager can manual select files to be managed without a space policy D in place thus allowing complete control over which data are shelved.   ApplicationsK Storage intensive sites which routinely archive or move data in response to J user requests or are faced with ongoing problems due to reconfiguration of storage due to constraints.   
