Detecting VMware, Citrix and MS HyperV Cluster….
Nowadays, server virtualization is commonly used in companies of any size starting from small companies to large data centers. Nearly all professional virtualization technologies support the idea of a resource pool. Image a resource pool as a set of servers and diskspace that can be freely used by virtual machines within the pool. The resource pools or clusters serve two purposes. Whenever a server fails, then the remaining servers can take over the virtual machines running on the failed server. Furthermore, administrators can easily extend resource pools by adding more disk drives or physical servers.
For administrators, it is essential to know which servers belong to a cluster. This information gets more and more important as software vendors license their software differently for virtual machines than for physical servers. For instance, RedHat allows you to pool licenses if you have an VMware ESX cluster! Knowing which operating systems and software runs in what cluster can save real dollars!
Therefore, we implemented with the help of a customer the cluster detection for the three major virtualization technologies:
- VMware ESX(i) Servers
- Citrix XenServer
- Microsoft HyperV
With JDisc Discovery 3.1 (Build 3101), you’ll get the list of physical servers that belong to a cluster and our custom reporting lets you list the cluster information for each physical and virtual machine.
