Chapter 5: PDU Linking
101
Pairwise Outlet Groups
The PDU Linking feature offers the "pairwise" functionality for outlet grouping.
Pairwise lets you create auto-named pairs of outlet groups than span multiple
PDUs (master and link units) using the same outlet label. Pairwise simplifies
outlet switching up or down a server by automatically creating multiple outlet
groups, each containing one pair of outlets between PDUs that can be
controlled as a pair-related outlet group.
Example: Chain with master and a single link unit
PDU 1 (Master Unit) Server Load PDU 2 (Link Unit)
Outlet 1 Server 1 Outlet 1
Outlet 2 Server 2 Outlet 2
Outlet 3 Server 3 Outlet 3
… … …
Outlet 20 Server 20 Outlet 20
Using the above example, to power up or down a server, you would typically
switch one outlet of PDU 1 and one outlet of PDU 2. With pairwise, you can
auto-create an outlet group named "Outlet pair 3", and the new group will
automatically contain Outlet 3 from PDU 1 (master) and Outlet 3 from PDU 2
(link). Powering up or down the server only requires switching the "Outlet pair
3" outlet group, allowing for improved accuracy and speed over outlet control.
Automatically Create Pairwise Outlet Groups
1. From the Outlet Groups page, from the drop-down menu select
Automatic Creation.
