Introducing Linux into the Enterprise
So now it's time for some of those cool tricks I promised. Would you believe me if I said that you can build a complete Windows 2000 or NT 4.0 server in just a few minutes under GSX? Or, how about multiple servers at the same time in under an hour? Here's how it works. The first build of an operating systems in GSX takes the usual amount of time to complete and configure, but if you need multiple servers with the same base build or similar configuration, you can copy the files created after the initial build to subsequent virtual server directories. Simply create the new servers in the web admin console as before, copy the server files, then change a few lines of information (such as server name and the pointers to the new server's disk files, *.dsk) in a config file (i.e., win2000.cfg). After that, power on the new servers and change their IP address, machine name, etc. It's a good idea to tarball the files, name them appropriately and copy them off to a DLT, CD burner, etc. Now pat yourself on the back because you built multiple identical servers in minutes. At this point you can customize your servers to be SQL, web, e-mail, etc.
In addition, GSX gives you a fast way to build multiple servers and a much quicker way to recover from a serious crash. In the event of an unrecoverable OS failure (you were backing up, weren't you?), rather than having to rebuild the OS and then restore your data, copy the server files from the tarballs that you created. Now restore your data and calmly say to yourself, "life is really, really good".
So there you have it--a high-powered Linux server that can host as many virtual servers as you have the memory and the horsepower for. I encourage you to visit the VMware site and check out the GSX Server product (there is also an ESX Server product that runs directly on top of the hardware--no OS), and give the 30-day demo a spin. For our purposes, Linux combined with VMware's GSX Server have been a real blessing.

Until recently, IBM’s Power Platform was looked upon as being the system that hosted IBM’s flavor of UNIX and proprietary operating system called IBM i. These servers often are found in medium-size businesses running ERP, CRM and financials for on-premise customers. By enabling the Power platform to run the Linux OS, IBM now has positioned Power to be the platform of choice for those already running Linux that are facing scalability issues, especially customers looking at analytics, big data or cloud computing.
￼Running Linux on IBM’s Power hardware offers some obvious benefits, including improved processing speed and memory bandwidth, inherent security, and simpler deployment and management. But if you look beyond the impressive architecture, you’ll also find an open ecosystem that has given rise to a strong, innovative community, as well as an inventory of system and network management applications that really help leverage the benefits offered by running Linux on Power.Get the Guide
