Routing (MCR) is an simple
shared disk and GVSAN (storage area network) configurations of
up to 8 gigabit can allow users on your network a direct "pipeline" connection to the Metropolis MCR; without the necessity for a multitude of expensive switch and routers. Users appear as network device(as an independent zone or grouped by department) just like output devices and storage volumes; and each pipeline can be easily reassigned or truncated, for greater throughput. Cascading and multi-directional application failover is
supported and application services can also be manually migrated to
alternative servers for maintenance purposes. A Java-based management
GUI provides a single point of administration for multiple Metropolis
MCR server. Metropolis MCR provides a comprehensive
availability management solution designed to minimize both planned and
unplanned down time.
On-line
storage management tools such as Metropolis Volume Manager and File
System provide various data availability options as well as allowing
common administrative tasks to be performed without shutting off client
access to the data.
The following are Metropolis 2000 Series of the package product:
Metropolis
Data Replication can replicate data between multiple nodes and multiple
sites to support disaster recovery and replicated application environments.
Implementing
cluster or availability management solutions is done with a single goal
in mind: to reduce the impact of downtime on business operations. To
maximize availability, a comprehensive approach that addresses potential
failures and potential administrative causes of downtime should be utilized.
GVS provides an end-to-end storage management solution that protects
availability from the point of data creation, through storage and use,
to backup and offsite archiving. Integration points (with the Metropolis
Cluster Server) all along this "data life cycle" for all of
GVS' Metropolis family of products.
