Setup Guide

Network

For best results, Overland Storage strongly recommends that you use a dedicated GbE network to share the storage resources on the REO Appliance among multiple backup servers.

To ensure optimum performance, always use the appropriate patch cables to connect the REO Appliance to the backup-server storage network. To select the appropriate cables, use the following guidelines:

„If you intend to use GbE, you must use Category 5E (or better) cables for GbE connections. You can use either straight-through or cross-over cables.

„If you intend to connect the REO Appliance to a 100 BaseT network, use CAT 5 (or better) shielded (screened) or unshielded 100-ohm twisted-pair RJ-45 network cables. Also:

„If you intend to connect the Management Port, which is a 10/100 port, to an application or backup server via a switch, you must use a straight-through cable.

„If you intend to connect the Management Port directly to your application or backup server (without a switch), you must use a cross-over cable.

„The maximum length of cable for any Ethernet-based network connection is 328 feet (100 meters).

Note: For smaller environments, you can attach the REO Appliance directly to a single application or backup server by using standard Category 5E cables without the use of a switch.

iSCSI Initiators

iSCSI initiators are required to communicate with the iSCSI targets (REO Devices) on the REO Appliance. Each backup server that will interface with the REO Appliance must be equipped with a software- or hardware-based initiator. The REO Appliance supports any computing platform with an available iSCSI initiator, either in software or using an iSCSI HBA (it must be iSCSI draft 20/version 1.0).
