NetApp SAN & Public Cloud Storage Maintenance
Posted by Kevin Stange on 04 December 2017 01:01 PM
We have scheduled maintenance to our NetApp SAN storage platform to replace a faulty controller card. The NetApp SAN is used to power the storage for our Xen Public Cloud and customer accessible SAN services hosted out of chi18. This maintenance does not affect the Datera SAN hosted in chi02.
Date: Sunday, December 17th, 2017
Due to the redundant nature of the SAN platform, the entire load will be transferred to a single controller box while the other is upgraded. This process will be performed for each controller and performance and stability will be tested before and after each change before continuing. When the load is transferred using a normal "takeover," there should be no interruption to service, though periods of slow response times may occur. While we expect the transfer of load to be seamless, if a failure condition should occur that may impact filesystem integrity, we will stop maintenance and proactively correct issues.
If you have any questions or need assistance during the upgrade, please contact us via our helpdesk.
