To configure shared storage in a vSphere cluster, follow these steps:
1. Identify and select the storage device and protocol you want to use as the shared storage. Common options include Fibre Channel, iSCSI, NFS, and vSAN.
1. Ensure that the storage device is configured and connected to all hosts in the vSphere cluster. Each host should be able to see and access the storage device.
1. Create a new datastore using the shared storage device. This can be done through the vSphere Web Client or the vSphere Client.
1. Give the datastore a unique name and specify the type of file system format (VMFS or NFS) that you want to use.
1. Enable vSphere High Availability (HA) and Distributed Resource Scheduler (DRS) to allow for automatic failover and load balancing of virtual machines.
1. Configure storage settings for each virtual machine in the cluster. This includes selecting the shared datastore as the storage location for virtual disks and configuring disk sharing between virtual machines.
1. Test the configuration by migrating virtual machines between hosts and ensuring that they maintain access to the shared storage.
1. Monitor and maintain the shared storage environment to ensure optimal performance and availability for all virtual machines in the vSphere cluster. This includes ensuring that storage resources are evenly distributed and avoiding overloading any one host or datastore.
