NEO 200s/400s User Guide
Mail Slot
A configurable import/export slot or magazine to provide a means of exchanging tape media
while the unit is still operating.
Mapping table
A table indexed by sequential LUN values, indicating the selected BUS:TARGET:LUN
devices. Mapping tables are used by routers and bridges like the GEOi to perform Ethernet-
to-SCSI pathing.
MD5 Algorithm
MD5 is a way to verify data integrity, and is much more reliable than checksum and many
other commonly used methods.
MIB
Short for Management Information Base. A formal description of a set of network objects
that can be managed using the Simple Network Management Protocol (SNMP). The format
of the MIB is defined as part of SNMP.
Mirroring
Used in RAID 1 and 10, a process of storing data on one disk and copying it to one or more
disks, creating a redundant storage solution. RAID 1 is the most secure method of storing
mission-critical data.
Mounted
A filesystem that is available.
MPIO
Short for Multipath Input/Output. A multipath solution built into Microsoft server-grade
operating systems. It requires the DSM to work with RAID storage array hardware.
MTU
Short for Maximum Transfer Unit. It is the largest size packet or frame, specified in octets
(eight-bit bytes), that can be sent in a packet- or frame-based network.
N_port
A Node port connects via a point-to-point link to either a single N_Port or a single F_Port.
N_Ports handle creation, detection, and flow of message units to and from the connected
systems. N_Ports are end ports in virtual point-to-point links through a fabric, for example
N_Port to F_Port to F_Port to N_Port using a single Fibre Channel fabric switch.
NAT
Short for Network Address Translation. A technique for passing network traffic through a
router whereby one set of IP addresses is used on one side of the router and another set of
addresses is used on the other side. This is done to avoid address conflicts and to increase
the address space of the internal network.
NDMP
Short for Network Data Management Protocol. A protocol standard used by some Network
Attached Storage systems to provide an industry standard means to do backup and restores
of the NAS system without the need for 3rd party agents to be installed on the NAS device.
