What are the typical UltraPath network topologies?
There are two typical UltraPath network topologies: direct connection network and switch connection network. Figure 1 and Figure 2 show the respective illustration.
Figure 1 Direct connection network
HBA = host bus adapter
NIC = network interface card
Figure 2 Switch connection network
In Figure 2:
The switches can be FC ones or Ethernet ones.
In an Ethernet switch connection network, if the iSCSI initiator maintains its default parameters, the working controller switchover takes about 2 minutes. If you want to shorten the time, contact Huawei for optimized iSCSI initiator parameter settings.
