Co-StandbyServer for Windows NT/2000
Your High-Availability Solution
Co-StandbyServer NT has earned industry recognition as the standard for others to aspire to (winner of several "Product of the Year" awards). For Windows 2000, Co-StandbyServer 2000 with its impressive list of new features and enhancements is setting out to continue that trend and leadership role.
enables two fully functioning Windows 2000/Advanced servers to act
as hot spares for each other in the case of application or server
failure. If a failure occurs, Co-StandbyServer 2000 ensures a
complete and reliable switchover. It transparently migrates the
applications, data and users from the failed server to the mirroring
New features for Co-StandbyServer 2000
Supports Windows 2000
Improved Mirroring Engine - Greater data integrity (additional acknowledgement), partition-level mirror.
Intelligent Resources - Resources can be configured to trigger failover.
Intuitive Application Modules - Proactive Management of Application Services (true "Application" switchover).
Powerful New GUI - Single Console Management, multiple instances.
Co-StandbyServer NT/2000 (Co-SBS NT/2000) ensures local high availability of applications and related data. Co-StandbyServer's block-level mirroring technology, and the use of a dedicated mirroring link, allows writes to be written to both servers at the same time. Unlike other solutions, this is done without adding additional traffic to the users production network. Co-StandbyServer does not require manual intervention after a server failure. Co-StandbyServer utilizes block-level synchronous mirroring vs. asynchronous replication at the file-level. The data is always in a known state avoiding problems associated with latency.
Co-Standby Server is the only block level mirroring solution for Microsoft NT/2000 that offers configuration flexibility (servers can be separated up to 10km through a designated link) and ensures true availability (99.99+%, 24/7) and access to mission-critical data and applications. COSBS's simplified implementation and management environment provides the ideal solution for small businesses or enterprise branch offices with limited or no on-site support. Existing industry standard hardware (does not require identical systems) can be utilized.
Co-StandbyServer NT/2000 for Windows
is a clustering system that assures high-availability of critical network resources. Data, applications, shares, IP addresses, and printers are covered by this pure protection solution. Legato's new data mirroring technology operates at the device driver level on individual I/O requests. Data is synchronized between the cluster servers. Mirroring traffic uses a separate, dedicated inter-server link that keeps your LAN bandwidth free for client/server applications.
Co-StandbyServer NT/2000 protects
critical SQL 7.0/2000
data by mirroring components from an SQL server to the secondary server in the clustered pair. The server not running SQL can be used as a redundant server or it can run other applications. In the event of a failure on the SQL Server, the surviving server quickly takes on the messaging responsibilities of the primary server. Co-StandbyServer ensures access to a complete and reliable application and data environment.
Co-StandbyServer NT/2000 protects
Microsoft Exchange 5.5
by mirroring components from an Exchange Server to the secondary server in the clustered pair. The server not running Exchange can be used as a redundant server or it can run other applications. In the event of a failure on the Exchange Server, the surviving server quickly takes on the messaging responsibilities of the primary server. Co-StandbyServer always ensures a complete and reliable application and data environment.
Co-StandbyServer 2000 provides high
availability for Microsoft Operations Manager 2000
by protecting the Microsoft Operations Manager events and performance data that are stored in a SQL 2000 database. Through the use of the SQL 2000 Application Module, Co-StandbyServer 2000 has the ability to move all necassary SQL 2000 resources from one machine to another in a matter of seconds. In the event the Microsoft Operations Manager database fails, Co-StandbyServer 2000 will quickly and automatically activate the database on a secondary machine, allowing all Microsoft Operations Manager procedures to continue. By ensuring the availability of Microsoft Operations Manager 2000, Co-StandbyServer 2000 provides the assurance that your critical data will be available as well as reducing the costs associated with down time. This is the latest in a series of solutions that provide true high availability for Microsoft's Windows environments.
