![]() ![]() IBM Power hardware is also designed, from the ground up, to cater for enterprise workloads - Its hard to find a bank that doesn't use IBM Power hardware for their backend. Whereas, on IBM PowerVM, you can have 40 cores in your cluster, and if you are only allocating 4 cores to the database, you only need to license for 4 cores. So if you have a Wintel cluster with 40 cores and are only using 4 cores for your database, you will still be required to license the database for 40 cores IBM PowerVM on the other hand, is certified by all major application vendors so that you only need to license for CPU cores that are allocated to the workload. The application costs on Wintel, can create bill shock for customers, as unless you are using the application vendors cloud service, you will have to license your whole Wintel Cluster - all cores - regardless of if you are using them for the application or not. ![]() IBM also charge software maintenance, but it covers both the hypervisor (PowerVM) and the operating system (IBM AIX or IBM i). When running on Wintel environments, you have the costs of the hypervisor and software maintenance, then you have the operating and software maintenance costs. ![]() When running IBM Power hardware, vs another vendors hardware, the same hardware maintenance costs are involved. IBM Power hardware is designed to maximize I/O while still providing flexibility when it comes to virtualization. ![]()
