Non-RAID The RAID level option that can be used for a virtual disk having a
single disk drive and that does not need the data redundancy or
performance benefits of RAID. The capacity of a non-RAID virtual
disk equals the capacity of its disk drive. For fault tolerance, use
RAID 1 or above.
NTP See Network Time Protocol (NTP).
originator The network device that originates an iSCSI login request to another
device (the recipient). For a login request from an iSCSI host initiator
to a storage system, the host is the originator and the storage system is
the recipient.
