Upgrade of a X4500 to a X4540

From time to time a question arrives at my desk. Just received it one more time a few minutes ago: “Can we update your X4500 system to an X4540 equvialent system? We want PCIe and QuadCores would be a nice idea, too”. Yes, you can. It´s the B24-FSZ2-4540-CONT on the Sun price list. That´s just the controller module of the X4540. You can use it to upgrade your X4500. There are certain differences between a X4540 and an upgradeded X4500 like the number of supported power supplies (two instead of three where available because of necessity). Ask your friendly SalesRep for additional information.
