Imagine that we have a thousand of servers at our disposal that do not have a system, but we alreadCMU_Screeny have the iLO network set up. With the iLO functionality in servers, we can mount the system image and install it, but how long would it take? It would be very long and tedious work. The rescue comes from the HP Insight Cluster Management, called HP CMU, which is designed to make the work of the Administrator quick and easy.

Having this, and through the Java graphical interface, we can see all servers in one window. When choosing any server, we prepare a ready image with the drivers on it. By clicking on the server, we prepare the so-called GOLD IMAGE, which we then run on all other servers via the PXE Boot network. It’s amazing, given that there can be up to 4096 servers, we can do the whole operation in just 2-3 minutes.

But that is not all we can do with the CMU system. It also helps us to upgrade iLO and BIOS quickly and easily. Just download the new firmware of iLO or BIOS our server from HP Webpage and save it to the /opt/cmu/firmware/ directory, and then upgrade all nodes in just 2 seconds. This tool also helps us to monitor not only each server separately, but all nodes simultaneously in one pane. We can see what load is on the node, what is the memory consumption, etc. Having this information, we can analyze and monitor our computing cluster on an ongoing basis. We also have the feature for disabling/enabling and resetting a particular server in the graphical user interface. We can therefore turn off all servers or restart them with one click. The UID locator also a useful function, which enables us to easily locate one server physically among all the others. Let us recall — 1 of as much as 4096 servers.

As I have already mentioned, the graphical interface of HP CMU is based on Java, which also helps us to append custom scripts and new functionalities.

In a word, I personally cannot imagine work today without getting advice from HP CMU.
