Apply updates to vmware Hosts

Posted on by

On July 20th I will be applying vmware updates to ESXi host in Prod 1,  2, 3 clusters. This is a rolling maintenance and will not create any outages for running guest vm’s.  As they will be live migrated off one blade at time as its put into maintenance mode and patches applied.

Regular remote access mechanisms like ssh or remote desktop to the VMs will be unaffected. All VMs and their services will continue to run as normal. There should be no customer impact.

HP StoreVirtual SAN Maintenance

Posted on by

** Emergency Maintenance Announcement – No service interruption anticipated **

We will be replacing a failed raid/rom battery in a fast disk node in our lefthand SAN. This is the storage network that back’s our VMware infrastructure.

We do not anticipate any service interruption. Our nodes are redundant for each other, we will only be working on a single node as such the change should not be service interrupting.
