Appendix A Cabling

Additional information to physically connect ports to devices and to your SAN.

Fibre Channel connections

The Fibre Channel port connects the bridge into either a Fabric or Arbitrated Loop.

The iPBridge 2700 uses optical SFP connectors and multimode fiber optic cable.

Cable length

Cable size

Up to 175 meters

62.5 micron

 

 

Up to 500 meters

50 micron

 

 

Make sure all cables are anchored securely at both ends with the proper connectors.

Ethernet connections

Use at least Cat 5e cable to connect the Ethernet ports to your network.

Note

For best performance, all cabling, network interface cards (NICs), host bus adapters (HBAs), and network switches must be Gigabit Ethernet (GbE), and at least Cat 5e certified. Most standard offices use 2-pair wiring which is not compatible. GbE requires 4-pair wiring.

For best performance, support for 9014 byte jumbo frames should be available for all switches and host iSCSI equipment.

Before you begin installing the iPBridge Ethernet ports, be sure to check or complete the following:

If you are managing your iSCSI system across a WAN and your system uses a firewall, be sure that the following ports are open and available: If you are using the TCP protocol

telnet (port 23)

http (port 80)

ftp (ports 20 and 21)

iSCSI (port 3260)

iSNS (port 3705)

If you are using the UDP protocol

ntp (port 123)

Be sure your host system(s) is set up and configured.

Your host system can use any of three different types of cards: a network interface card (NIC), a TCP/IP offload engine card (TOE), or a storage network interface card (SNIC).

The ATTO driver file from the CD included with your iPBridge or from the ATTO website, www.attotech.com, is installed on your host.

The switch has been configured to forward UDP broadcast messages.

The minimum requirement for Windows-based browsers is Internet Explorer 5.5 or Netscape Navigator 6.2. The minimum requirement for Macintosh browsers is Internet Explorer 5.2 or Safari 1.2.

Ethernet speed defaults to auto; the iPBridge will determine the speed and set other parameters based on the speed.
