iSCSI (Internet SCSI) is a protocol which encapsulates SCSI (Small Computer System Interface)
commands and data in TCP/IP packets for linking storage devices with servers over common IP
infrastructures.
Fibre Channel
Fibre channel is an extremely fast system interface. It was initially developed for use primarily
in the supercomputing field, but has become the standard connection type for storage area
networks (SAN) in enterprise storage.
SAS
Serial-attached SCSI offers advantages over older parallel technologies. The cables are thinner,
and the connectors are less bulky. Serial data transfer allows the use of longer cables than
parallel data connections.
SSD
An SSD (Solid-State Drive) is a solid-state storage device that uses integrated circuit assemblies
as memory to store data persistently.
Thick Provisioning
Thick provisioning is allocated upon creation the physical disk drive space and is equal to the
user capacity seen by the host server. It also called fat provisioning.
Thin Provisioning
Thin provisioning is allocated on-demand and can be less than the user capacity seen by the
host server. It involves using virtualization technology to give the appearance of having more
physical resources than are actually available.
Snapshot
A volume snapshot is the state of a system at a particular point in time.
Local Clone
Local clone function has another physical data copy as the original volume.
