Cluster Management Console
Our web-based utility offers real-time monitoring of performance and load activity. It supports dynamic runtime configuration of cluster settings, maintenance, and groupings via a web interface for remote or local administration to expand your ability to maintain your system. The built-in security features give the protection you need for a secure business solution.
Application Stability Agents
These agents continuously monitor the cluster to determine the health of services. We include agents for the most popular services as well as tools to create custom agents for proprietary services. Together these agents provide total customization for your solution.
Heterogeneous Server Clustering
Our technology supports clustered server groups running Linux, Unix and Windows NT/2000/XP. While the traffic manager operates on a Turbolinux platform, your applications can be clustered on their current platform with no additional coding effort.
What Services Can Be Clustered?
Many typical network services can be clustered with the Cluster Server product. The main requirement is that the service must be able to be run on more than one machine at a time. Just about any TCP/IP service will work. The following services are commonly used with Cluster Server:
- Web sites (HTTP, HTTPS)
- FTP
- Email (SMTP, POP3, and IMAP)
- News (NNTP)
- DNS
- Database (DB2, Oracle)
Turbolinux Cluster Server should generally not be used to cluster database servers that are write-intensive. There is no built-in locking mechanism between cluster nodes, so if more than one cluster node is writing to the same database, data could become corrupted. If you need to cluster a database, you do have a few options. If you use the cluster to read the database, and another single system to write to the database, everything should work fine. Another method is to use a two-tier model, with web servers within the cluster accessing a database server behind the cluster.
