The connector labeled '1' in the exhibit is a Quad Small Form-factor Pluggable (QSFP) connector. This type of connector is used for high-speed interconnects, including 4X InfiniBand (such as QDR and FDR) and 40GbE. NetApp systems utilize these cables and connectors for the private cluster interconnect network, which requires high bandwidth and low latency. The "4X" designation in InfiniBand signifies that the link uses four parallel data lanes, a configuration supported by the QSFP physical interface.

A. 3: This is an RJ-45 connector, which is used for standard Ethernet networking (e.g., 1000BASE-T, 10GBASE-T), not InfiniBand.

C. 2: This is a Small Form-factor Pluggable Plus (SFP+) connector, typically used for 10Gb Ethernet or 8/16Gb Fibre Channel, not 4X InfiniBand.

D. 4: This is an external Mini-SAS connector (SFF-8088 or SFF-8644), used for connecting controllers to disk shelves via the SAS protocol.

1. NetApp FAS8000 Series Installation and Setup Instructions: In the section "Step 3 Cable the controllers

" the guide provides diagrams of the controller's rear panel. It explicitly identifies the InfiniBand cluster interconnect ports as using QSFP connectors

which visually match connector '1' in the exhibit. (See "Rear view of the FAS8020/FAS8040/FAS8060 controller module

" page 28).

2. NetApp CN1610 Cluster-Interconnect Switch Installation and Configuration Guide: This document shows the different ports available on a NetApp cluster switch. It clearly illustrates SFP+ ports (matching connector '2') and RJ-45 management ports (matching connector '3')

distinguishing them from the QSFP ports used for the main interconnect. (See "CN1610 switch front panel

" page 10).

3. NetApp Universal SAS and ACP Cabling Guide (TR-4089): This technical report details the cabling for disk shelves. It includes images and descriptions of Mini-SAS connectors (SFF-8088) and Mini-SAS HD connectors (SFF-8644)

which match the appearance of connector '4'. (See "SAS Connectors

" page 6).
