Nature of the work- Upgrade NetApp clusters
Which data center(s)- Lindquist Center (LC) and Information Technology Facility (ITF)
Expected impact on services- Each volume will experience two brief (10-30 seconds) pauses in IO
Expected duration- 3 hours
Date and Time- Saturday, November 19, 2016 from 6:00 AM to 9:00 AM
Nature of the work- Upgrade the F5 chassis systems (two in LC and two in ITF)
The F5 chassis systems host all F5 GTM/DNS and LTM systems in the following way: ITF chassis 1 (ITF primary LTM, ITF GTM/DNS), ITF chassis 2 (ITF secondary LTM); LC chassis 1 (LC primary LTM, LC GTM/DNS). Each chassis will be upgraded, one at time, resulting in the GTM/DNS and LTM systems hosted on the chassis being unavailable for a period of time.
The LTM systems are redundant and services will be moved between the primary and secondary systems as needed. The GTM/DNS systems are redundant and provide the same data. No more than one GTM/DNS and one LTM system will be unavailable at any time.
Expected impact on services- No service impact is expected.
Which data center- LC and ITF
Expected impact on services- None
Expected duration- 2 hours in LC; 2 hours in ITF
Date and Time- Saturday, November 19, 2016 from 4:00 AM to 8:00 AM
