To install the StoneFly Storage Concentrators into a Telco type rack, use two L-shaped
brackets on either side of the chassis (four total). First, determine how far follow the Stor-
age Concentrator will extend out the front of the rack. Larger chassis should be positioned
to balance the weight between front and back. If a bezel is included on your Storage
Concentrator, remove it. Then attach the two front brackets to each side of the Storage
Concentrator, then the two rear brackets positioned with just enough space to accommo-
date the width of the Telco rack. Finish by sliding the Storage Concentrator into the rack
and tightening the brackets to the rack.
The StoneFly Storage Concentrators should now be securely mounted into the rack/cabi-
net in which they were installed.
Step 4: Cabling the Equipment
The cabling plan is straightforward to describe and must be followed to make the USO-HA
completely functional. The following description shows the steps for two Storage Concen-
trator components, two storage arrays, and one expansion unit. Additional storage compo-
nents are connected in a similar manner.
Storage Concentrator Ethernet connections are made between one or more switches and
the Ethernet ports on each Storage Concentrator in the cluster. In a configuration with
dual-gigabit Ethernet connections in each Storage Concentrator both connectors in the
PCI slot must be filled with standard Cat5 or Cat6 cable. A clustered pair of Storage Con-
centrators presents several configurations of Ethernet ports (maximum per cluster):
1
Six or Ten 1 GbE ports
2
Two, Four or Eight 10 GbE ports
