    1 Introduction This chapter provides an introduction to PS Series storage arrays and groups and describes the steps for getting started. PS Series Arrays and Groups PS Series storage arrays deliver the benefits of consolidated storage in a storage area network (SAN) that is affordable and easy to use—regardless of its size. With intelligent, automated management and fast, flexible scalability, PS Series arrays greatly reduce storage acquisition and management costs.
  • Page 10 Installation and Setup Introduction Figure 1-1: Group With One Member To connect to a volume, a computer needs only a standard iSCSI initiator. Volume access can be restricted through IP address, initiator name, or CHAP (Challenge Handshake Authentication Protocol) credentials. Once connected, the volume is seen by the computer as a regular disk that can be formatted as usual.
