Based on
NSI Software's proven Double-Take replication technology, GeoCluster
extends the capabilities of Microsoft Cluster Service (MSCS) to create
a stretch cluster.
While MSCS,
and clustering in general, provides a high level of application availability,
MSCS clusters maintain only a single copy of the data and only provide
failover within a single site. Built on top of MSCS, GeoCluster offers
added data protection, assuring continual access to data and applications
across sites.
GeoCluster
provides:
- Multi-site
disaster recovery protection Real-time, continuous offsite data
protection and failover to ensure that business-critical data and
applications can be recovered quickly, despite complete failure at
any single site
- Improved
data availability
With byte-level replication ensuring maximum application performance
and minimum bandwidth requirements, GeoCluster reduces exposure to
data loss and eliminates the single point of failure of shared disk
storage
- Reduced
downtime
Application failover is fast and automatic, eliminating or greatly
reducing any downtime
- More
flexibility
Only replicated drive letters and capacity need to match between cluster
nodes making it possible to create clusters using existing servers
and storage. GeoCluster supports active/active configurations where
each node can be supporting production users but failover for the
other node as required.
- Lower
cost option than building a traditional cluster
Since replication occurs over standard IP LAN or VLAN connections,
dedicated links, channel extenders or storage routers are not required.
Endorsing
GeoCluster, Michel Gambier, Group Product Manager of Enterprise Marketing
for Microsoft Corporation, stated, "We are excited to see NSI Software
taking advantage of the cluster service in Microsoft Windows 2000 to
add advanced capabilities such as data replication. By combining the
capabilities of Microsoft Cluster Service with the capabilities of NSI
Software's GeoCluster, our customers can realize even higher levels
of availability and protection for their business-critical applications
and data." |
