Terminology
3ware SAS/SATA RAID Controller CLI Guide, Version 9.5.1
uses the
following terminology:
Logical Units.
Usually shortened to “units.” These are block devices
presented to the operating system. A logical unit can be a one-tier, two-tier, or
three-tier arrangement. Spare and Single logical units are examples of one-tier
units. RAID 1 and RAID 5 are examples of two-tier units and as such will
have sub-units. RAID 10 and RAID 50 are examples of three-tier units and as
such will have sub-sub-units.
Port.
3ware controller models up to the 9650SE series have one or many ports
(typically 4, 8, 12, 16, or 24). Each port can be attached to a single disk drive.
On a controller such as the 9650SE with a multilane serial port connector, one
connector supports four ports. On 9690SA series controllers, connections are
made with phys and vports (virtual port).
Phy.
Phys are transceivers that transmit and receive the serial data stream that
flows between the controller and the drives. 3ware 9690SA controllers have 8
phys. These “controller phys” are associated with virtual ports (vports) by
3ware software to establish up to 128 potential connections with SAS or
SATA hard drives. Each controller phy can be connected directly to a single
drive, or can be connected through an expander to additional drives.
VPort.
Connections from 3ware 9690SA controllers to SAS or SATA drives
are referred to as
virtual ports
, or VPorts. A VPort indicates the ID of a drive,
