Multiple Array, Lan Switch, Woc Connection With Two Wans - Hitachi AMS 2000 User Manual

Multiple array, LAN switch, WOC connection with two WANs

Figure 3-12, shows two local arrays connected to two remote arrays, each
via two LAN switches, WANs, and WOCs.

Recommendations
• If a Gigabit Ethernet port (1000BASE-T) is provided on the WOC, the
LAN switch to the WOC is not required. Connect array ports 0B and 1B
to the WOC directly. If your WOC does not have 1Gbps ports, the LAN
switch is required.
• You can reduce the number of switches by using a switch with VLAN
capability. If a VLAN switch is used, port 0B of local array 1 and WOC1
should be in one LAN (VLAN1); port 0B of local array 2 and WOC3
should be in another LAN (VLAN2). Connect the VLAN2 port directly to
Port 0B of the local array 2 and WOC3.
