Move VMware Cluster Dell FX2 Chassis to FCN - COMPLETED

Incident Type:        Scheduled Maintenance

Start Time:           December 9, 2017 8:00AM

End Time:             December 9, 2017 12:20PM

Service Type:         Production

Symptoms:             Some intermittent slowness may be experienced throughout the production server environment.
                      No downtime is expected for any major production service.

The four server blades (VMware compute nodes) which are part of the server chassis in the CW Data Center must be relieved of their burden, and all virtual servers being run on them must be actively taken over by the remaining environment residing in FCN Data Center. Therefore, during the "handoff", some slowness is to be expected across the board. Canvas and the Google suite will not be affected by this, or any other services residing in the cloud and/or are being provided by Ann Arbor.

12/5/2017 @ 8:27AM - This maintenance is rescheduled from its original date of 11/12/2017 which was postponed due to weather conditions. The work is planned for Saturday, December 9th with a fallback date to Sunday, December 10th if weather again intervenes.

12/9/2017 @ 12:20PM - Maintenance completed. All ESX servers back online.
