Glossary
and integrated hardware and software. A file system is located and
managed on the NAS device and data is transferred to clients over
industry-standard network protocols (TCP/IP or IPX), using
industry-standard file-sharing protocols.
node
Any device with a Fibre Channel interface (such as an HBA in a
server or a storage system’s SP) that connects to a Fibre Channel loop.
P
PDU (power
distribution unit)
A device for the distribution of ac line power from one inlet to
multiple outlets. Multiple PDUs in a rackmount cabinet provide
higher availability since the power continues if one PDU (or its ac
source, if the PDUs use separate ac sources) loses power.
power supply
A device to connect ac mains power to low voltage dc power for the
system components. A CX700 has two power supplies, PS A and PS
B. With two, it can survive failure of one supply. You can replace a
power supply under power, without interrupting applications.
R
replace under
power
The capability that allows you to replace a FRU (for example, a disk
module or a fan module) without powering down the storage system.
Applications continue while you replace the failed module.
S
SAN (storage area
network)
A high-speed special-purpose network (or subnetwork) that
interconnects different kinds of data storage devices with associated
data servers on behalf of a larger network of users.
server
In the context of storage systems, a processor that runs an operating
system and uses a disk-array storage system for data storage and
retrieval.
SP (storage
processor)
A printed-circuit board with processor memory modules and control
logic that manages the storage-system I/O between the server FC
adapter and the disk modules.
SP memory
module
A memory module (DIMM) that provides the local storage for an SP.
