Fibre-channel cabling
Fibre channel is used to connect storage nodes to storage servers and to connect
storage servers to storage expansion units.
KVM cabling
The KVM switch allows a maximum of eight connections. Use the following
guidelines for cabling the KVM switch:
v Use the information on each end of each cable to create a site map.
v When routing a KVM cable from a cabinet containing cluster nodes to another
cabinet containing the KVM switch, connect a C2T-to-KVM cable to the cluster
nodes and use a KVM extension cable to add sufficient length to reach the KVM
switch.
v Multiple KVM switches can be connected in series. Cluster nodes can be
connected in series to a single KVM switch port, but the management node and
all the storage nodes each require a separate KVM switch port. Certain systems
might require a second KVM switch. Install the second switch in the expansion
cabinet that contains the additional storage nodes.
v When using two KVM switches, connect Port A (the console port) of switch 2 to
port 8 of switch 1. Use a KVM extension cable to make the connection between
the two cabinets. If more length is needed, use two KVM extension cables linked
together.
Remote console manager cabling
The remote console manager (RCM) switch has 16 ACT connections (KVM over
RJ-45/CAT5) and one KVM connection for the console. Use the following
guidelines for cabling the RCM switch:
v Use the information on each end of each cable to create a site map.
v When routing a CAT5 KVM cable from a cabinet containing cluster nodes to the
cabinet containing the RCM, use a CCO cable and a CAT5 cable sufficiently long
enough to reach the RCM switch.
v Multiple KVM switches can be connected in series.
v Up to 40 cluster nodes can be connected in series to each ACT port on the RCM.
The management node and all the storage nodes can also be daisy-chained, with
up to 16 per ACT port. Multiple RCMs can not be daisy-chained together. The
RCM can be connected to an Ethernet network to allow for remote access to the
consoles of the servers over the network.
Local console manager cabling
The local console manager (LCM) switch accepts the CAT5 input from the NetBay
Conversion Options and allows them to be fed into your management station. Its
four CAT5 input ports support four chains of 16 servers per chain. The local
console manager (LCM) switch also supports Cable Chaining Technology (C2T).
Use the following guidelines for cabling the LCM switch:
v Use the information on each end of each cable to create a site map.
v When routing a CAT5 KVM cable from a cabinet containing cluster nodes to the
cabinet containing the LCM, use a CCO cable and a CAT5 cable sufficiently long
enough to reach the LCM switch.
v Multiple KVM switches can be connected in series.
v Up to 16 cluster nodes can be connected in series.
