Hi,
Can someone tell me the difference between a da LUN and a datastore?
My understanding is that that a datastore is what you see in the Vsphere client - i.e. either a local disk on an ESXi host or a collection of disks\parts of a disk within a SAN.
A LUN, from my understanding is a logical unit number which is used to identify a piece of storage at the end of a Fibre Channel or SCSI cable. A LUN can represent a single disk, multiple disks or a portion of one or more disks.
I've read it's not advisable to put multiple data store on a single LUN, however I'm assuming it's generally OK to have multiple LUNs to a single data store?
Vmware has a 256 LUN limit, would this limit mean you have a 256 datastore limit?
Apologies, storage is not my strong point and I've seen lots of examples where the terms LUN and datastore are used interchangeably.
Thanks
