General description The HP StorageWorks 8/20q Fibre Channel Switch (Figure 1) is a 20-port, 8-Gb/s switch with both Ethernet and serial management interfaces. This section describes the features and capabilities of the HP StorageWorks 8/20q Fibre Channel Switch and includes information about the following features: •...
Switch LEDs and controls The switch LEDs provide information about the switch’s operational status. These LEDS include the Input Power LED (green), Heartbeat LED (green), and the System Fault LED (amber) (Figure 2). For information about port LEDs, see ”Port LEDs”...
Maintenance button The Maintenance button (Figure 2) is a dual-function momentary switch on the front panel. Its purpose is to reset the switch or to place the switch in maintenance mode. Maintenance mode sets the IP address to 10.0.0.1 and provides access to the switch for maintenance purposes when flash memory or the resident configuration file is corrupted.
Fibre Channel ports The 8/20q Fibre Channel Switch has twenty Fibre Channel ports. Ports are numbered 0–19 (Figure Each of the ports is served by a Small Form-Factor Pluggable (SFP+) transceiver and is capable of 8-Gb/s, 4-Gb/s, or 2-Gb/s transmission. •...
Port Activity LED (green) The Activity LED indicates that data is passing through the port. Each frame that the port transmits or receives illuminates this LED for 50 milliseconds. This makes it possible to observe the transmission of a single frame. Transceivers The 8/20q Fibre Channel Switch supports SFP+ optical transceivers for the Fibre Channel ports.
Ethernet port The Ethernet port is an RJ-45 connector that provides a connection to a workstation through a 10/100 Base-T Ethernet cable (Figure 5). A workstation can be a Windows or a Linux server that is used to configure and manage the switch fabric. An Ethernet connection to the switch is required to manage the switch using the CLI, QuickTools, Simple SAN Connection Manager, or Simple Network Management Protocol (SNMP).
The serial port connector requires a null-modem F/F DB9 cable. The pins on the switch RS-232 connector (Figure 6) are identified in Table 3. For information about connecting the workstation through the serial port, see ”Connect the management station or workstation to the switch”...
QuickTools web applet QuickTools is a browser-based graphical user interface (GUI) that provides switch management capabilities beyond those of Simple SAN Connection Manager. You run QuickTools by opening the switch IP address with an internet browser on your workstation. See the HP StorageWorks 8/20q Fibre Channel Switch QuickTools Switch Management User Guide.
A zoning database is maintained on each switch. Table 4 describes the zoning database limits, excluding the active zone set. Table 4 Zoning database limits Limit Description MaxZoneSets Maximum number of zone sets (256). MaxZones Maximum number of zones (2,000). MaxAliases Maximum number of aliases (2,500).
Latency Latency is a measure of how fast a frame travels through a switch from one port to another. The factors that affect latency include transmission rate and the source/destination port relationship (Table Table 5 Port-to-port latency Destination Rate Gbps Source <...
Domain ID, principal priority, and domain ID lock The following switch configuration settings affect multiple switch fabrics: • Domain ID • Principal priority • Domain ID lock The domain ID is a unique number from 1–239 that identifies each switch in a fabric. The principal priority is a number (1–255) that determines the principal switch which manages domain ID assignments for the fabric.
Transparent routing IMPORTANT: The Simple SAN Connection Manager (SSCM) application version 2.10 can manage 8/20q Fibre Channel Switches with active TR_Ports; however, SSCM cannot manage or discover remote switches or devices in the remote fabric. Use QuickTools and the storage management interface to present Logical Unit Numbers (LUNs) to remote devices.
fabrics, the interoperability mode must be configured to InteropMode=0. Other B-Series or C-Series switches in the remote fabric need not support NPIV. NOTE: Be sure to configure the TR_Port before connecting the remote fabric to the HP StorageWorks 8/20q Fibre Channel Switch. If the remote fabric is connected to a port on the HP StorageWorks 8/20q Fibre Channel Switch that is not a TR_Port, the two fabrics may establish an E_Port connection and the local and remote fabrics may merge.

• QuickTools web applet (EmbeddedGUI): Provides for access to the QuickTools web applet. QuickTools enables you to point at a switch with an internet browser and manage the switch through the browser. The default is enabled. • Simple Network Management Protocol (SNMP): Provides for the management of the switch through third-party applications that use the Simple Network Management Protocol (SNMP).
Security Security is available at the following levels: • User account security, page 26 • IP security, page 26 • Port binding, page 26 • Connection security, page 26 • Device security, page 27 User account security User account security consists of the administration of account names, passwords, expiration date, and authority level.
The SSL handshake process between the workstation and the switch involves the exchanging of certificates. These certificates contain the public and private keys that define the encryption. When the SSL service is enabled, a certificate is automatically created on the switch. The workstation validates the switch certificate by comparing the workstation date and time to the switch certificate creation date and time.
Fabric management The Simple SAN Connection Manager application is a GUI-based management application for HP StorageWorks that runs on the management station. It provides basic automated configuration and management of switches, HBAs, and storage devices. Switch management functions include IP address configuration and limited control of zoning.
