Overview
This section provides information related to upgrading a Cisco HyperFlex Stretched Cluster. The procedure for performing a Stretched Cluster upgrade is similar to the regular HyperFlex cluster upgrade procedure.
Cisco HyperFlex Stretched cluster upgrade process involves upgrading the below 3 components:
-
Cisco HyperFlex Data Platform1
-
VMware vSphere ESXi
-
Cisco UCS Server Firmware
You can combine HyperFlex Data Platform and VMware ESXi upgrade in a single combined upgrade for HyperFlex Stretched clusters using the installer. You can choose to upgrade one or two of these components at a time.
If you prefer to upgrade individual components one at a time, see Upgrade UCS Firmware, HX Data Platform and VMware vSphere - Individual Component Upgrade. The component upgrade process for standard cluster and HyperFlex Stretched cluster are the same.
This section describes the steps to perform a combined upgrade of HyperFlex Data Platform and VMware vSphere ESXi. In this process, the HyperFlex nodes will go through an optimized rolling reboot without any workload disruptions by use of VMware vMotion.
