Product Description

Overview

The Hewlett-Packard SureStore E hub, short-wave model S10 and long-wave model L10, is a full-duplex, 1063-megabit-per-second hub. It increases loop reliability, number of loop connections, and distances between server and mass storage devices in a Fibre Channel Arbitrated Loop. The hub’s port detection and bypass circuitry dynamically detects and bypasses a failed node on the loop. Nodes can be added, removed, and reconnected without bringing down the loop and disrupting communication for other nodes.

Fibre Channel Manager is a web-based software application that allows you to remotely manage and monitor the health of the hub. To learn more about Fibre Channel Manager, visit the Hewlett-Packard (Software Depot (http://www.software.hp.com). Fibre Channel Manager is available as a free download from this web site.

Older hubs may require a firmware upgrade to meet Fibre Channel Manager’s minimum requirements. The Software Depot web site has more information about this. The latest hub firmware and upgrade instructions are available as a free download from this web site.

Detailed configuration information and part numbers for the hub are provided in chapter6, Reference.

12 Overview

Features

HP SureStore E hubs provide the following features:

• Short-wave hub (model S10): 10 non-Open Fibre Control (non-OFC) short-wave

optical transceivers

• Long-wave hub (model L10): nine non-OFC, short-wave optical transceivers and one

non-OFC, long-wave optical transceiver

• Local retime and regeneration of transmit signals to prevent accumulation of jitter and

improve the signal

• Reliable, automatic bypass of failed nodes; dynamic recognition of newly added or

removed nodes, with a controller in each port permitting the bypass of a port if the port fails signal validity tests

• Active loop reconfiguration when a node to an arbitrated loop is added, removed, or

moved

• Plug-and-play capability, which allows the hub to connect to compatible servers and

other Fibre Channel Arbitrated Loop (FC-AL) devices while they are operating ( FC-AL devices can be added or removed while the hub is active.)

• Cascade support (hub-to-hub connections) for increased loop distances

Cascaded short-wave hubs are supported up to 500 meters; cascaded long-wave hubs are supported up to 3000 meters (3 km). Under certain conditions, cascaded long-wave hubs are supported up to 10,000 meters (10 km) (see page105 for more information). The 10-km capability only applies to long-wave hubs connected to HP-UX servers.

Product Description

Note Increased loop distances are associated with increased latency times.

• Access to the RS-232 interface for firmware upgrades and hub configuration and

troubleshooting

• Support for a hub management tool (Fibre Channel Manager) to remotely manage and

monitor the health of the hub

Features 13

Front Panel, Model S10 Short-Wave Hub

The front panel contains LEDs for monitoring power, fault, and port status. The RS-232 port is provided to configure and troubleshoot the hub and to upgrade its firmware. The 10Base-T port provides an ethernet connection if you choose to manage the hub with Fibre Channel Manager.

Supported Topologies

Devices such as FC-AL disk arrays and HP system servers that support FC-AL can be connected to the hub in a loop that includes one or more servers. All nodes in the loop must be 1063 Mbps short-wave, non-OFC, FC-AL. The ports connected by a cable must have the same optical transceivers. Figure4, Figure5, and Figure6 show typical hub topologies. For details on supported topologies, contact an HP sales representative.

Single Short-Wave Hub Topology

For the model S10 short-wave hub, Hewlett-Packard recommends 50-micron multimode fiber cable for new installations, but also supports 62.5-micron multimode fiber cable with SC-style connectors in existing installations. Stated distances assume 50-micron multimode cable.

A server with an FC-AL short-wave adapter can connect to an hub 500 meters away. Each of the 10 ports on the short-wave hub can connect to an FC-AL device up to 500 meters away. The maximum distance between the server and the end FC-AL device is 1000 meters (1 km).

Cascaded Short-Wave Hub Topology

The example in Figure5 shows two model S10 hubs connected in a cascade topology. Cascaded short-wave hubs use one port on each hub for the hub-to-hub connection. Such a configuration increases the potential distance between nodes in the loop an additional 500 meters. The maximum distance between the server and FC-AL devices with cascaded short-wave hubs is 1500 meters (1.5 km).

Cascaded hubs must have the same firmware versions to operate properly. If you are using Fibre Channel Manager to manage cascaded hubs, configure the hub that has the LAN (ethernet) connection as a parent hub and the remaining hub as a child hub (see Configuring Cascaded Hubs on page60).

18 Supported Topologies

Cascaded Long-Wave Hub Topology

Cascaded FC-AL, non-OFC, model L10 long-wave hubs use the long-wave port for the hubto-hub connection. The maximum supported distance between cascaded long-wave hubs with single-mode 9 micron cable is 3 km. The maximum distance between a server and FCAL devices on cascaded long-wave hubs is, therefore, 4000 meters (500m + 3000m + 500m). Under certain conditions, cascaded long-wave hubs are supported up to 10,000 meters (10km) (see page105 for more information). The 10-km capability only applies to long-wave hubs connected to HP-UX servers.

Caution When cascading long-wave hubs, only connect long-wave ports to long-wave

ports or short-wave ports to short-wave ports.

Ports 1 through 9 on each long-wave hub are for connections to FC-AL devices. Ports 1 through 9 can also be used in a cascaded configuration; however, the maximum distance between hubs decreases from 3000 meters to 500 meters.

Maximum distance between server and FC-AL device = 4000 m

NOTE: Under certain conditions, the maximum distance between an HP-UX server and FC-AL device can be 11,000 m.

Read this chapter completely before installing the hub or attaching any FC-AL devices to the hub.

22 Overview

Procedure 1: Prepare to Install the Hub

Before installing the hub:

• Complete site-required arrangements for the hub.

• Make sure electrical power and temperature control requirements are met.

• Define a strategy for integrating the hub into an existing loop.

• Draw a map of all nodes to be connected to the hub.

Installation

Procedure 1: Prepare to Install the Hub 23

Procedure 2: Unpack the Hub

1. Unpack and inspect the hub for damage that may have occurred during shipment.

2. Save the boxes and packing materials in case there is damage or anything needs to be reshipped at a future date.

3. Verify that all items shown in Figure7 are present. Contact an HP sales representative if items are missing.

4. If the hub is to be used as a standalone unit, attach the four rubber feet to the bottom corners of the hub. Optionally, remove the hub’s preinstalled mounting ear brackets and nylon retainers. The brackets and retainers are used to mount the hub in a rack.

Procedure 3: Verify Hub Operation

By performing this procedure, you test the hub and verify that it operates properly before you mount it in a rack or connect any devices to it.

1. To initialize the self-test, first plug the power cord into the hub and then into a power receptacle. The hub does not have a power switch.

The hub runs the self-test each time the power cord is plugged in or the Reset button is pressed.

Note The hub’s power supply automatically adjusts to a range of 100 VAC ±10% or

240VAC ±10%.

2. The hub finishes the self-test in less than 15 seconds.

If the Fault LED (amber) stays on after self-test, the hub failed. Refer to chapter 4, Troubleshooting, or contact an HP service representative for assistance.

If the Power LED does not light, refer to chapter4, Troubleshooting, or contact an HP service representative.

Installation

Note Interruptions to the hub’s AC power source initiate a self-test. Make sure the

power source circuits are properly grounded before using the supplied power cord to connect the hub to the circuit.

3. Verify that each Fibre Channel port is operating properly. Insert the loopback cable into the port and verify that the port status LED turns on. Both ends of the loopback cable plug into the port connectors.

If you plan to use Fibre Channel Manager to manage the hub, continue with step4. If you do not plan to use Fibre Channel Manager or another hub management tool, go to step7.

Procedure 3: Verify Hub Operation 25

4. Verify that the 10Base-T port is operating properly. Insert an ethernet cable that is connected to the LAN into the 10Base-T port, and verify that the 10Base-T status LED turns on. (The status LED may begin flashing.)

5. Set the hub IP address and configure the hub as described in chapter 3, RS-232 Interface Functions.

6. Verify the connection between the HP-UX server and the hub. At the management server where Fibre Channel Manager is or will be installed, execute the following command:

/etc/ping <hub IP address> Example: /etc/ping 15.43.214.13

Fibre Channel Manager requires HP-UX 10.20 or 11.0 on the management server.

If you are unable to ping the hub, refer to If the Management Server Cannot Ping the Hub on page78.

7. Unplug the hub.

26 Procedure 3: Verify Hub Operation

Procedure 4: Mount the Hub into a Rack (Optional)

The hub mounts into any standard HP 19-inch wide EIA cabinet. The hub’s front panel will face the rear of the cabinet. The front of the hub contains the 10 Fibre Channel connectors. You will need a T25 Torx head screwdriver to complete this procedure.

1. Record the serial number, located on the bottom of the hub, and the MAC address, located under the 10Base-T port. The MAC address is unique and cannot be changed.

2. Verify that the rack is adequately secured and has enough space (1 EIA) for the hub. Remove filler panels as needed from the front of the cabinet and open the rear door.

3. If the rubber feet are attached to the bottom of the hub, peel off the feet. Attach the mounting ear brackets and nylon retainers if they are missing from the left and right sides of the hub (Figure8).

Secure the mounting ear brackets with three M3 x .5 screws to each front outside corner, turning the angled end of the bracket outward. Attach the nylon retainers with one screw through the center of the retainer and into the hole in each side of the hub.

4. Slide a sheet metal nut onto the outer column in the back of the rack. Make sure to align the hole in the nut with the hole at the selected EIA location on the column.

Procedure 4: Mount the Hub into a Rack (Optional) 27

5. Insert one end of the left rail in the adjoining slot. Line up the hole in the rail lines with the holes in the nut and column (Figure9).

6. Use a second sheet metal nut and repeat steps 4 and 5 to attach the other end of the rail to the inner column on the front of the rack.

Note DO NOT attach screws at this time.
