2 PS Series Storage Arrays
PS Series Storage SANs provide a peer storage architecture comprised of one or more independent
arrays. Each array contains its own controllers, cache, storage, and interface ports. Grouped together
they can create one or more single instance storage pools that are based on the IETF iSCSI standard.
The capabilities of the PS Series solution are provided through a unique set of software and hardware
capabilities that, when used cooperatively, can provide a full featured SAN solution. The following
sections provide additional insight into specifications and functions of PS Series arrays.
2.1 Array Models
Starting with the PS5000 family of arrays, Dell EqualLogic model names designate various pieces of
information regarding the PS Series array. The "PS" is the product name and stands for "Peer Storage".
The four digit model number indicates the major feature sets and generational information. The first
digit is the "family" and is typically referred to as the "x-thousand" family where "x" is (currently) either
5 or 6. The second digit designates the chassis form-factor (16 drives vs. 48 drives). The last two are
digits designate the controller type (―00‖ indicates a controller with 1GbE ports, ―10‖ indicates a
controller with 10GbE ports).
The letter designation at the end of the model name indicates the array drive technology being used
within the array: "E" indicates SATA technology, "X" indicates 10,000 RPM SAS technology, "XV" indicates
15,000 RPM SAS technology and "S" indicates SSD technology.
