CHEYENNE HSM for NetWare Cheyenne HSM provides you with the flexibility to manage the greatest amount of data at the least expense, while optimizing access to all files. Cheyenne HSM is the storage management system for on-line data across any combination of media which best meets your cost and response time requirements. The key to HSM is the automatic move-ment of data, called migration, from server hard disk to less expensive storage medium. File migration is managed by administrator-configurable migration guidelines based on storage utilization, file age and frequency of access. Because much of your data will be automatically transferred to less expensive storage medium, the overall cost of storage (including related administrative expenses) will decrease. Because HSM moves data intelligently (based on the parameters you set), it balances cost reduction with user access requirements. Critical files will remain on hard disk for immediate access. Migrated files are accessed, as usual, through this volume, so that network users will achieve relatively fast access to inactive files normally relegated to off-site archiving. At Cheyenne we realize that the best products should be easy-to-use. That's why we've designed Cheyenne HSM with an intuitive Windows GUI interface. We also realize that your company has unique needs, and that those needs may change with time. Therefore, Cheyenne HSM offers a variety of flexible migration rules which can be tailored to your changing specifications, while supporting a wide variety of media, devices, and clients. Cheyenne HSM is your comprehensive data/storage management solution for the present, and for the future. CHEYENNE HSM: The Flexible Hierarchical Storage and Data Management System for NetWare networks. The Dilemma: Although it is important for users to retain easy access to all files, it often comes at an unacceptably high price Two scenarios are likely inactive files remain on hard disk wasting valuable resources storing rarely-accessed files, or inactive files are moved to another, often off-site, location, dramatically compli-cating access to these files. Is there another, better alternative? The answer is a resounding YES! The Solution: Cheyenne HSM retains critical files on the hard drive and offers transparent retrieval of files which have been migrated off the hard drive, yet may be accessed through your primary server. Cheyenne HSM moves ''dormant" files from high cost server hard drive to less expensive media, until finally, they reside on the least expensive media. To retrieve a network file, no matter how old, the user need merely access the file through the network directory, and the file will be retrieved with minimal delay. It's as simple and efficient as that! INTUITIVE INTERFACE
FLEXIBLE MIGRATION MANAGEMENT Cheyenne HSM enables you to design your HSM strategies to fit your company's unique needs. Two sets of migration rules, watermarks and retention rules, combine to determine which files migrate, and when. The administrator defines these rules based on his knowledge -- of the network and of the needs of the users. Once all migration rules are defined, migration may he scheduled to run at a specific hour, for a specific length of time, and may be repeated as often as required. While in most cases these migration rules adequately manage all files, occasionally, the administrator may perform ad-hoc migration or de-migration (selecting specific files or directories to be moved off, or returned to, a server hard drive).
REDUCES OVERALL STORAGE COSTS  As
an administrator you must weigh cost factors against the need for improved
data access and long-term file retention. Cheyenne HSM will help you lower
thc related administrative and hardware expenses of retaining rarely-used
files, by moving these files to less expensive storage media. The HSM hierarchy
offers two separate stages (secondary and tertiary) beyond primary storage,
in which you may use a variety of high capacity hard drives, optical devices
(WORM and Rewritable), and tape devices, as alternative storage media Based
on the parameters you set, HSM will automatically migrate files to the
appropriate medium, and de-migrate them upon demand. With Cheyenne HSM
your time is freed to focus on network performance, rather than storage
capacity. Cheyenne HSM also contains cost through minimizing' hardware
requirements. You can maximize your investment in storage by selecting
a configuration which shares server(s) and storage devices for all your
data management requirements.
IMPROVES FILE ACCESSIBILITY With Cheyenne HSM, network users access ALL files from within their network directory, without the aid of an administrator! As files are migrated from server hard drive, a "stub" is created in primary storage for each file. This stub contains all pertinent file information including the location to where the file has moved, so that it may point HSM to your file for speedy access. For those who desire maximum flexibility and minimal idle time, an optional messaging TSR may be installed on your workstation. When opening a migrated file Cheyenne HSM notifies the user that the file they are opening is a migrated file and provides an estimate of retrieval time. The user may then choose to "release" their workstation and continue working while file retrieval occurs in the background. COMBINES WITH ARCSERVE FOR FULL DATA PROTECTION Cheyenne HSM does not replace your current backup system for archiving and disaster recovery, it complements it. It works seamlessly with Cheyenne's ARCserve for NetWare Windows Edition. With ARCserve you can backup the Cheyenne HSM server(s) so that files not yet migrated, as well as migration stubs for those files which have been migrated, are protected. In addition, Cheyenne HSM's own backup utility offers the fastest recovery for media failure or disasters by performing media-to-media copy at the secondary and tertiary levels. DESIGNED FOR GROWTH The flexibility of environments and devices with which Cheyenne HSM operates ensures that when your company grows, Cheyenne HSM will grow along with you. You may start with a simple environment with all three levels of storage on a single, non-dedicated server. Eventually, you may move each hierarchical stage to it's own dedicated server, thus improving file access, so crucial to a network with hundreds of gigabytes of network data. Additional drives, optical jukeboxes and tape autochangers can be added at any time. Cheyenne HSM also supports of a variety of clients (including DOS, OS/2, Windows, Windows NT, Macintosh, and UNIX) to accommodate an increasing variety of network users for your complex network environment.
Supported Devices Magnetic SCSI hard drive & drive arrays Optical WORM, rewritable, drives & jukeboxes Tape QIC cartridge, 4MM, 8MM, drives, & autochangers "Yes it runs with NetWare" logo denotes developer tested only. Novell makes no warranties with regard to this product. |
Both
Cheyenne HSM and Cheyenne ARCserve Windows Edition use a similar Windows
GUI for system administration. The HSM manager guides the network administrator
through the definition of all migration rules and all other data management
tasks. Cheyenne's intuitive front-end features straightforward icons for
rapid setup, a simple menu system, and on-line help screens. Any network-attached
workstation can manage the entire HSM system. Additionally, the HSM manager
features CheyenneHSM Expert, a rich set of real-time utilities which monitor
and analyze data storage/management, including a bona fide modeling utility.
This utility helps you to choose the optimal migration configura-tion by
testing the outcome of several migration schemes before actually migrating
any files.
