Prerequisites for VMware vCenter ESX Servers

Verify that the following prerequisites are met before provisioning storage for VMware vCenter ESX servers.

Install the required adapters
Depending on the type of storage available, your VMware vCenter ESX Server requires the following adapters for connectivity to specific storage devices or networks:
- ISCSI Adapter for an ESX
  The ESX/ESXi software iSCSI initiator built into VMkernel communicates with the network adapter through the network stack to facilitate the iSCSI connection. Use the vSphere Client Configuration tab and click Storage Adapters in the Hardware panel to configure the iSCSI adapter.
- Fiber Channel HBA
  Use the default configuration settings for Fiber Channel HBA.
Configure Discovery Addresses for iSCSI Initiators
Set up target discovery addresses so that the iSCSI initiator can determine which storage resource on the network is available for access.

Note: For more information about installing and configuring the required adapters, see the VMware website.
