Configuring Vmware for Storage.

if I understand Configuring Vmware for Storage is made up of 2 phases.
1-We configure Vmkernels for Multipathing  on the vSwitch...
 2- we also need to configuring ESX host physical adapters to talk to the storage...

Something that needs to be configured under the storage Tab of ESX host... any steps on how to achieve that ?

Thank you

1. All Shared Storage NFS and iSCSI needs a VMKernel Portgroup. It's also best practice to reduce a single point of failure to ensure this is at least two paths. Hence the term multi-path. Whether VMware Admins or Architects or apply this best practice is up to them.


2- we also need to configuring ESX host physical adapters to talk to the storage...

If you want to connect ESXi to Shared Storage NFS, there is nothing more to do other than connect to NFS export.

If you want to use the iSCSI software adaptor, you need to add it!

So if ESX host has HBA as adapters then you run the scan on vsphere client to discover them then add them.
if ESX host has just regular NICs then we add ISCSI software adapters and rescan them

If you are lucky enough to have an Hardware iSCSI Adaptor, or ToE card, of iSCSI HBA it's usually all ready configured (at the BIOS) with an IP Address and IQN - and you are correct, you select the Adaptor and select -Re-scan HBA.

When you re-scan the HBA, if it finds LUNs (if SAN and LUNs have been configured) - you can then Add (new) Storage and format them with VMFS and create a Datastore.

if no hardware, then you would use the Software iSCSI adaptor, which is emulated in software, and follow above...

(for both you need to add the IP Address of the SAN)
