Featured Reviews

Atif Najam - PeerSpot reviewer
A stable system for high-end data processing with a great support structure
The only problem with the IBM system is improving its hardware licensing model. For example, when you procure a server with 40 physical codes, you must also procure licenses to activate the codes. In Dell or any system, you procure the hardware and have the full right to use the hardware. For IBM, it's different because when you procure a 40-code processor and have 40 physical codes, you only have a license to use 20. As a result, the 20 alert codes will always be in activated mode. Hence, the hardware licensing model could be improved because the licensing model is a bit different from the standard hardware procured.
