Controller Module - Seagate Exos AP 4U100 Installation And Maintenance Manual

Controller module

This section describes the Controller module used in Exos AP 4U100 12Gb/s storage enclosures. It is used as a server
module.
The Figure 18 shows a Controller module taken out from the enclosure. You need to insert the Controller module with the
same orientation as shown in the figure below.

The Controller module (a.k.a. Server module) is an Intel server module that is designed for integration into the Seagate
Exos AP 4U100 enclosure. The Exos AP 4U100 enclosure is designed to accept two Controller modules providing
connectivity to drives.
Each Controller module is a server, with either 1, or 2 Intel x86 CPUs and associated storage, interface, add-in card, and
management subsystems. Each Controller module features 2 low profile Peripheral Component Interconnect Express
(PCIe) slots that support a variety of qualified PCIe cards including SAS HBAs and high-speed Ethernet adapters. These
PCIe slots allow attachment to a host via Fibre Channel (FC), or Fibre Channel over Ethernet (FCoE), or Internal Small
Computer Interface (iSCSI), or other methods, as required.
Figure 19 provides a description of the controller module that installs into the rear panel of an Exos AP 4U100 enclosure.
The module is shown resting on its base. To install the module into one of the Controller module slots located on the
enclosure rear panel, you would first revolve the module by 90º along its longitudinal axis, before inserting it into a slot as
shown in Figure 4 (page
