base cabinet The system’s main cabinet, which contains a Data Services Platform (DSP),
trays, a Storage Service Processor, a service panel, power distribution units
(PDUs), a USB flash disk, and an Ethernet hub and is pre-wired with Ethernet,
Fibre Channel, and power cables. The base cabinet can be connected to one or

concatenated volume One of the logical devices that can be constructed through concatenation so
that storage capacity is not limited to the actual physical size of an individual
disk. You concatenate multiple virtual disks to form a volume. You use a
concatenated volume to store a large file or file system that spans more than
one disk.
