RoSE_STEM
has given Stratus users the full tape library management functionality
normally available
with mainframe tape library systems. With the decrease in cost of high capacity
disks, more and more data
is being stored on Stratus computers. This data is often of a critical, extremely
important nature and, as
with any computer system, must be backed-up. RoSE_STEM gives you the ability to
standardise your
back-up procedures in a reliable way to enable you to know when and where your data
was backed-up.
|
When combined with automated or robotic devices, RoSE_STEM offers you the ability to
have a
completely operatorless backup and retrieval system for your entire Stratus based
file and data set.
RoSE_STEM provides full control over tape devices and tape volume handling. RoSE_STEM
maintains
databases of tape libraries and saved objects. The saved object database allows
reports to be generated
showing when a particular object was saved and to which volume that save was written.
Using its database,
the RoSE_STEM product can immediately identify which volume to mount in order to
restore a particular
object. RoSE_STEM supports all tape writing operations for backup together with the
relevant reading for
retrieval operations:- save, write_tape, dump_disk, dump_sql etc. Furthermore, all of
the tape operations
are 100% compatible with the standard operating system equivalents.
Automation of Tape Jobs
Regularly performed tape jobs can be configured in a database. The configuration will
include all of the
necessary tape writing parameters and a list of the data to be saved. The tape job
will be given a name
which will be used to submit that job without having to remember any of the
configured parameters.
The submission of jobs can be performed manually or may be put in the operating
system batch queues for
automated execution. When this facility is combined with one of the supported robotic
devices, all of your
backups can be done without operators.

Support For All Secondary Storage Media RoSE_STEM can be used with 1/2" tape drives, 3480 and DAT drives with or without stackers, 8mm Exabyte™ drives. RoSE_STEM can also control Exabyte™ tape robots and StorageTek™ Silos for completely automated backup environments. RoSE_STEM is 100% compatible with standard VOS tapes formats and commands.
Restoring Files
To successfully and speedily restore a file the following information must be readily
available:

STEM_NET - DAT saves to V-Series
If
you have a requirement to read VOS format DAT save tapes that you
created on your Continuum(s) on your new V-Series modules then STEM_NET
solves that issue. Our
solution utilizes our mature tape library management product, RoSE_STEM
and a new adjunct product STEM_NET. This will allow users to restore DAT
tapes in VOS save format created on a Continuum ( or XA/R) module to
V-Series, from a DAT tape drive connected to a
PC running MS Windows 95 or later. This
is done using bespoke software we have written for MS Windows,
which then transfers the data from the DAT tape over IP
to communicate with
a STEM_NET process on VOS in conjunction with
RoSE_STEM.
The PC will require a SCSI or USB DDS DAT tape drive either internal or
external .These drives are readily available and are plug and play. Using
STEM_NET we can restore VOS DAT Save Tapes made on Continuum to the
V-Series at the same speed as you can natively restore to Continuum. |
RoSE_STEM - With Encryption RoSE_STEM With Encryption, including 3 DES and AES, is available as an NOW and is in production use at several sites on V-Series. You can also use RoSE_STEM With Encryption on Continuum, but we question whether it will be usable due to the time overhead. In general we therefore only recommend RoSE_STEM With Encryption on V-Series. We have a full series of options for key management built into RoSE_STEM as follows:-
(i) User
configured key, stored clear and visible The infrastructure is in place to implement other options at user request. There is no hardware involved in our solution at all.
