High Availability and Clustering
High Availability and Clusters
Would server downtime be disastrous for your business? Clustering can help you to create a network where resources can withstand most kinds of outages without interruption. It will allow you to build a site where users won’t notice if a server goes down or a switch fails. Clustering also can allow you to increase efficiency in your IT infrastructure – performing maintenance on one server in the cluster while the other is still live.
DSI are authorised partners for RSF-1. RSF-1 is a mature high-availability and cluster middleware application that ensures critical applications and services are kept running in the event of system failures. It sits between the storage volume management and application layers of typically: web servers, application servers, firewall servers and database servers, providing support for most leading applications in those areas.
RSF-1's strength is in its "does exactly what is says on the tin" functionality which provides a very simple, but powerful, configuration and management framework that allows customers to deploy High-Availability solutions in a matter of hours rather than days or weeks and with a minimum of fuss.
With optional monitoring agents for many popular databases, middleware and end-user software, RSF-1 is able to switch critical applications from servers with network, hardware, OS, or application failures to alternative servers in the cluster to minimise downtime. Incorporating feature-rich command-line and GUI interfaces, RSF-1 allows manual and automated fail over of up to 200 critical applications and services within a 2 to 64 node cluster.
RSF-1 is available on a wide variety of platforms including: Intel 32bit, Sun SPARC, PA RISC, Opteron, and supports a wide variety of operating systems including: Solaris, HP-UX, Red Hat 7, Red Hat 8, Red Hat 9, Red HAt EL3, Red Hat EL4, Fedora Core 4, SuSE 9, RedFlag 4.
RSF-1 comes with a comprehensive set of support options from simple "e-mail by return" response to enterprise class 24x7 Platinum Services depending upon what you actually require and not vendor mandated as seems to be the norm with other cluster solutions. Indeed we extend this lack of "hidden extras" to installation and training whereby in most circumstances installation and user training is included in the price.
Along with RSF-1 DSI are also partners for Sun Microsystems and Symantec (Veritas) Therefore also provide solutions on Sun Cluster Server and Veritas Cluster Server should your environment require so.
