I cannot say of my own, personal, experience. But I was told that the Unisys ES7000 Intel servers are capable of "tolerating" an CPU failure. The CPU becomes unusable and the work running on that CPU must be recovered and restarted (I.e. it "abends" because there is no ACR like on z/OS). I was futher told that Windows Datacenter Edition will mark the CPU as unusable and no longer try to run work on it. However, the CPU is not hot-repairable, so you run degraded until you can take an outage to replace it. I was told similar things about memory and I/O buses. Again, I cannot guarantee the accuracy of these statements. -- John McKown Senior Systems Programmer UICI Insurance Center Information Technology This message (including any attachments) contains confidential information intended for a specific individual and purpose, and its' content is protected by law.
