Replacing Existing Hardware Components in vSAN Cluster

Under certain conditions, you must replace hardware components, drivers, firmware, and storage I/O controllers in the vSAN cluster.

In vSAN, you should replace hardware devices when you encounter failures or if you must upgrade your cluster.

vSAN ESA contains a single storage pool of flash devices. Each flash device provides caching and capacity to the cluster. For more information on how the vSAN ESA is designed, see the vSAN Planning and Deployment guide.
