ODM
(Online Data Manager) and Disk Mirroring for SCO
OpenServer 6
The
new, low cost SCO
Online Data Manager (ODM) and Mirroring add-ons for OpenServer 6
provide
customers with the tools to easily manage and protect their business
critical
data.
ODM is a
separately installable component that requires the Maintenance
Pack and provides
advanced data redundancy and recovery. A separate
license is required, which can be entered before
or after
installing ODM using the SCOadmin License Manager (scoadmin license).
ODM is a software solution for RAID systems and replaces the OpenServer
5 VDM (Virtual Disk Manager) product.
There are two different versions available:
The Disk Mirroring product,
which only allows for setup of RAID1 configurations, is a low cost
alternative to entry level RAID controllers available on the
market.
Customers who just
need software disk mirroring solution to enhance the availability of
disk
storage systems without any other RAID features, have the option of
purchasing
an OpenServer 6 Mirroring license. The Mirroring option
for OpenServer 6 provides increased data
availability by providing fault tolerance against disk failures and
faster data
access. By adding a second disk to the
system and adding Mirroring, administrators will automatically have
access to
their business-critical data should one disk fail.
SCO Online Data Manager for
OpenServer 6 provides software RAID Levels 0, 1, 5, 10 as well as
on-line disk
performance analysis. It includes a graphical Visual Administrator for
exceptional ease-of-use, and supports online filesystem resizing,
migration,
and RAID level modifications. ODM is a cost-effective, enterprise-class
storage
management solution for high availability and online volume management.
ODM
provides
enterprise data management features such as online volume
administration,
online filesystem backup, improved synchronous write performance and
further
enhances filesystem I/O performance using enhanced I/O clustering. I/O
clustering is a technique of grouping multiple I/O operations together
for
improved performance. With ODM, large file access performance is
comparable to
that provided by raw disk. ODM also supports dynamic disk defragmentation and online filesystem
resizing.
With
ODM, the system administrator
can visually identify ‘hot spots’, or high activity areas on disks.
These can
then be moved closer together to reduce disk seek times or moved to
other disks
to increase performance. It also features hot-relocation,
the ability of a system to automatically react to
I/O failures and restore redundancy and data access, saving the
customer
valuable time and money.
ODM supports:
- concatenation
(data is mapped linearly onto one or more subdisks in
a plex)
- spanning
(concatenation using
subdisks that reside on more than one VM disk)
- striping
(a technique of
mapping data so that the data is interleaved
among two or more
physical disks)
- logs for mirror
recovery
