path PCI Express (PCIe) port port instance RAID SAN SAS SATA SNMP SPI SSSU A path to a device is a combination of a HBA port instance and a target port as distinct from internal paths in the fabric network. A fabric network appears to the operating system as an opaque network between the HBA (initiator) and the target. Since a path is a combination of an HBA and a target port, it is distinct from another path if it is accessed through a different HBA and/or it is accessing a different target port. Consequently, when switching from one path to another, the driver might be selecting a different HBA (initiator), a different target port, or both. This is important to the driver when selecting the proper method of failover notification. It can make a difference to the target device, which might have to take different actions when receiving retries of the request from another initiator or on a different port. A third-generation input/output (I/O) standard that allows enhanced Ethernet network performance beyond that of the older Peripheral Component Interconnect (PCI) and PCI Extended (PCI-X) desktop and server slots. The higher performance of PCI Express derives from its faster, serial-bus architecture, which provides a dedicated, bi-directional I/O with 2.5-GHz clocking, beneficial to Ethernet network connectivity for desktops, workstations, and servers. Access points in a device where a link attaches. The four types of ports include the following: • N_Port (Node Port)-an FC port that supports point-to-point topology. • NL_Port (Node Loop Port)-an FC port that supports loop topology. • F_Port (Fabric Port)-a port in a fabric where an N_Port can attach. • FL_Port (Fabric Loop Port)-a port in a fabric where an NL_Port can attach. The number of a port in the system. Each HBA may have one or multiple ports, identified with regard to the HBA as port 0, port 1 and so forth. to avoid confusion when dealing with a system containing numerous ports, each port is assigned a port instance number when the system boots up. So Port 0 on an HBA might have a port instance number of, for example, 8 if it is the eighth port discovered by the system. Redundant Array of Independent Disks, a family of techniques for managing multiple disks to deliver essential cost, data availability, and performance characteristics to host environments. For details about the supported RAID types for your storage subsystem, refer to your HP MSA documentation. Storage area network, multiple storage units (disk drives) and servers connected by networking topology. Serial attached SCSI; a data transfer technology designed to move data to and from computer storage devices such as hard drives and tape drives. Serial advanced technology attachment; the new standard for connecting hard drives with serial signaling technology. Simple Network Management Protocol is a standard way for computers to share networking information. In SNMP, two types of communicating devices exist: agents and managers. An agent provides networking information to a manager application running on another computer. The agents and managers share a database of information, called the Management Information Base (MIB). Security parameter index, an identification tag added to the header while using IPsec for tunneling IP traffic. This tag helps the kernel discern between two traffic streams where different encryption rules and algorithms may be in use. HP Storage System Scripting Utility software (SSSU), a powerful scripting utility. The SSSU provides a host to array communications bridge for documenting and automating EVA local and remote configuration tasks. HP StorageWorks Simple SAN Connection Manager user guide 141
