7 1 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 chapter describes the features and capabilities of the HP StorageWorks 8/20q Fibre Channel Switch. You can manage fabrics with the Command Line Interface (CLI), the QuickTools web applet, or the optional Enterprise F ...

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” (page 10). The Maintenance button (Figure 2) is the only switch control. It is used to reset a switch or to recover a disabled switch. To apply power to the switch, plug the power cord in ...

9 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. For more informatio ...

The 8/20q Fibre Channel Switch has twenty Fibre Channel ports. Ports are numbered 0–19 (Figure 3). 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. • SFPs are hot-pluggable. • User ports can self-discover both the port type and transmission speed when connected to devices or other switches. • The port LEDs are located above ports 0–9 an ...

11 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. A transceiver converts ...

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, Enterprise Fabric Management Suite, Simple SAN Connection Manager, or Simple Network Management Protocol ( ...

13 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 2. For information about connecting the workstation through the serial port, see ”Connect the management station or workstation to the switch” (page 38). Power supply and fans The switch has a single power supply that converts 100–240 VA ...

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. QuickTools provides the following management features: • Faceplate device management • S ...

15 Storage Management Initiative–Specification (SMI-S) SMI-S provides for the management of the switch through third-party applications that use the SMI-S. For more information, see the HP StorageWorks 8/20q and SN6000 Fibre Channel Switch CIM Agent Reference Guide. File transfer protocols FTP and TFTP provide the command line interface for exchanging files between the switch and ...

17 2 Planning a Fabric This chapter contains information about planning a fabric. Devices When planning a fabric, consider the following: • The number of devices and the anticipated demand. This will determine the number of ports that are needed and in turn the number of switches. • The transmission speeds of your HBAs and SFPs. The switch supports 2-Gb/s, 4-Gb/s and 8-Gb/s tra ...

of 8-Gb/s with a maximum frame size of 2,148 bytes. Related performance characteristics include the following: • Distance, page 18 • Bandwidth, page 19 • Latency, page 19 Distance Consider the physical distribution of devices and switches in the fabric. Choose SFP transceivers that are compatible with the cable type, distance, Fibre ...

19 Bandwidth Bandwidth is a measure of the volume of data that can be transmitted at a given transmission rate. A Fibre Channel port can transmit or receive at nominal rates of 8 Gb/s, 4 Gb/s, or 2 Gb/s depending on the device to which it is connected. This corresponds to full duplex bandwidth values of 1,700 MB, 850 MB, and 424 MB respectively. Multiple source ports can transmit t ...

HP StorageWorks 8/20q 4-port Upgrade License activates additional Fibre Channel ports to 12, 16, or 20 ports. Applying a license key is not disruptive, nor does it require a switch reset. To order a license key, contact your switch distributor or your authorized reseller. For more information, see ”Installing feature license keys” ...
