Appendix A Glossary
Cache backup
Because a cache memory uses DRAM, information stored in
it is lost when the subsystem power is shut off. To provide
against unexpected power failure, the subsystem has an
setup to maintain data in the cache memory by batteries.
Cache backup is a state in which the data is protected by
the batteries.

Common Internet File System
CIFS is the extension of SMB protocol used in the file
sharing service of the Windows.
The specification is disclosed so that the CIFS can be used
in the OS other than Windows.
CSMA/CD is the LAN access method used in Ethernet.
When a device wants to transmit data, it monitors the
transmission status of a cable. If the cable is free, the
device transmits data. If the cable is not free, the device
waits a random amount of time before retrying. If more
than two devices start a transmission at exactly the same
time, a collision occurs in a cable. They both back off and
wait a random amount of time before retrying. The
CSMA/CD enables multiple devices to communicate
sharing one cable.
CUDG
Data LAN
interface
Control Unit Diagnosis
LAN interface in NAS unit that takes access from the
NFS/CIFS client. User LAN interface provides Copper 4
ports for one NAS unit, and supports 1Gbit/s.
Destage
Automatically writes data in cache memory, not yet
written on the disk drive, on the disk drive when the main
switch is turned off.
DHCP
DHCP is an abbreviation for Dynamic Host Configuration
Protocol; it is a client/server type protocol according to
which a server automatically assigns an IP address when
each client has started.
