Cable Interfaces Supported
Your Drobo uses the following two types of ports.
Note: Only the USB cable interface or the iSCSI (Ethernet) cable interface can be used
at any one time. If both are plugged in, only the USB interface will be active.
USB 2.0
USB (Universal Serial Bus) is a popular interface that allows you to attach additional
hardware devices to your computer in a plug-and-play style. On the Drobo B800i, this
connection is used only for initial setup and administrative purposes, after which the
iSCSI (Ethernet) connection is used.
iSCSI (Ethernet)
iSCSI (Internet Small Computer System Interface) is an Internet Protocol (IP)-based
networking standard for connecting storage devices to computers. By using a high
performance Ethernet connection, iSCSI can be used over long distances on your
existing network infrastructure. It’s also ideal for high volume data storage traffic and
is designed to be a direct block-level protocol that reads and writes directly to the
storage device.
With two iSCSI ports on the Drobo B800i, you can maximize performance. You can
configure each port to a different network so that both networks have access to the
Drobo B800i. You can also connect one port directly to the host computer and the other
to a network via a router.
With iSCSI, you have the flexibility to set up your Drobo B800i in one of three
configurations: directly connecting it to the host computer (for best performance),
connecting it to a switch in which another Ethernet port on the switch is connected
to the host computer, or connecting it to a switch (or router) in which another
Ethernet port on the switch (or router) is connected to your network. For the latter two
configurations, you will need to manually set IP addresses for the ports. You will do this
during the setup process. See “Setting Up in Just a Few Steps!” on page 7 for more
information.
