Multimaster and satellite
Opsware's multimaster replication engine and satellite
functionality give administrators the ability to build
and manage servers located in any data center or remote
location from a single console. It is designed specifically
for IT organizations that are tasked with managing servers
in multiple locations. The multimaster replication engine
helps keep global data centers synchronized by automatically
replicating key data components of the Opsware System's
information system across all data centers. The Opsware
Satellite breaks through the difficultities bandwidth
constraints and network complexity to deliver data center
quality of service to remote servers.
Automating multiple data center and remote facility
operations provide the following unique benefits:
Replicates all the information needed to build
or manage a server. The multimaster replication
engine synchronizes the information and software required
to build or manage a server.
Enables remote management from a single console.
Administrators can use the Opsware Command Center to
build and manage servers in remote data centers or remote
facilities. The Opsware System automatically routes
management tasks to the right server using intelligent
proxying techniques to locate and transmit instructions
to servers in other data centers.
Replicates software on-demand. Opsware's
intelligent replication and caching algorithms ensure
that only the software packages needed in a particular
data center are stored locally.
Replicates information in near real-time.
The Opsware System automatically replicates all crucial
information needed to build or manage a server in near-real
time.
Secure communication channels. The
Opsware System replicates information over a secure
connection offered by underlying services. Unauthorized
users are prevented from viewing the traffic or introducing
their own data into the communication channel that connects
data centers.
Unified and replicated audit trail.
The Opsware System maintains a digitally signed audit
trail of all the management tasks Opsware users performed
on a server. This log is automatically replicated among
or between data centers, ensuring that multiple copies
of the audit trail exist.
