Chapter 5 Configuring the xStack Storage Array
Figure 5-20 shows an example of a LAG created between the xStack Storage Array and a Gigabit
Ethernet switch. In this example, multiple initiators (servers) that are used in a load balancing
configuration can form one high-speed aggregated link. In this figure, the xStack Storage Array is
connected to a Gigabit Ethernet switch using four 1 Gbps links. If one link fails between the
xStack Storage Array and the switch, the other links in the LAG take over the traffic and the
connection is maintained. A different example can be shown using the same figure but in a non-
load balancing configuration and with a larger number of initiators aggregated into the LAG. In
this example, there could be six initiators connected to the switch that can participate in the
LAG. At any point in time, if one initiator is generating less traffic, the others can generate more
traffic, up to a maximum of 4 Gbps and the switch will balance the load. Since a single initiator
does not typically generate continuous data, this configuration can allow better overall
bandwidth utilization.
Figure 5-20. Example of Link Aggregation between the xStack Storage Array and a Gigabit Ethernet Switch
Using the following procedure, you can change this mapping so that a LAG consists of more than
one physical port, depending on the requirements of the network (i.e., the more ports in the
LAG, the more bandwidth and more redundancy that is available). When you create LAGs, you
can indicate whether the LAG is to support a virtual LAN (VLAN). All xStack Storage Array models
support eight VLANs, one for each IP address. As you create LAGs, record the information in
Appendix B.
