Storage System – This is the hardware itself, which manages disks into logical units (RAID). LUN – Logical Unit Number – A part of logical unit. One logical unit can consist of multiple LUNs (and usually does) RAID, JBOD (Just a Bunch of Disks), Hot Spare, Parity SP – Storage Processor

WWN (World-Wide Name) – 64 Bit number, to which we can attach a label
Fabric – part of SAN storage, components which are part of one access path (serverport, switch, storage port)
HBA – Host Bus Adapter – the card which connects a host to the Fiber Channel network (SAN Switch)

Storage security – Which ESX host should see which LUN?
SAN Zoning – A method, which makes it possible to create logical groups containing WWN nodes over the physical Fabric Channel network; it is applied on the FC switch level; it is similar to VLANs used in Ethernet networks
LUN Masking – A method, which makes it possible to „hide” certain Luns from certain hosts; usually implemented on HBA level FC / SAN Switch – The most important component of the FC network, the HBAs can be connected to the SAN switch
