Expansion ports (also referred to as drive ports)
The DS4300 controller drive/expansion ports are used for extending the storage
capacity from the internal DS4300 chassis. They are use for data transfer between
the drives in the DS4000 storage expansion enclosures and the RAID controllers in
the DS4300 Storage Subsystem. There is only drive/expansion port per controller.
The drive/expansion port from each controller must be connected to the same set of
DS4000 storage expansion enclosures to support redundant drive loop
configurations (two data paths per storage expansion enclosure). DS4300 Storage
Subsystems support only one redundant drive-loop pair. The DS4300 single
controller model does not have any expansion ports.
Ethernet ports
There are two Ethernet interface ports, one for each controller (Controller A and
Controller B). Use the Ethernet ports to directly manage (also referred to as
out-of-band management ) DS4300 storage subsystems. With controller firmware
version 6.xx.xx.xx, the default IP addresses for controllers A and B Ethernet ports
are 192.168.128.101 and 192.168.128.102, respectively. The default subnetmasks
for these ports are 255.255.255.0. The DS4300 single controller model has only
one Ethernet port (because it has only one controller).
