- Two-Rack Cabling

- Three-Rack Cabling

- Four-Rack Cabling

- Five-Rack Cabling

- Six-Rack Cabling

## E.1 Understanding Multirack Cabling

You can connect multiple Oracle Big Data Appliance racks or a combination of Oracle Big Data Appliance racks and Oracle Exadata Database Machine full racks, half racks, or quarter racks. Exadata racks must have a spine switch. If your Exadata rack does not have a spine switch, then be sure to have an Exadata Expansion Switch Kit on hand for the installation.

The Oracle Big Data Appliance rack has a Sun Datacenter QDR InfiniBand Switch for the spine switch at rack unit 1 (U1). The rack also has two Sun Network QDR InfiniBand Gateway switches for the leaf switches at rack units 20 and 24 (U20 and U24). See Figure D-1.

These switches attach to standard quad small form-factor pluggable (QSFP) connectors at the end of the InfiniBand cables. You can cable together up to eight racks without external InfiniBand switches. The cable lengths in this appendix are for adjacent racks. If they are apart, then longer cables may be required for the connections.

### E.1.1 Cabling the Switches in One Rack

In a single rack, the two leaf switches are connected by seven cables. Each leaf switch has one cable to the spine switch. Nine servers connect to one leaf switch, and the other nine servers connect to the other leaf switch, as shown in Figure E-1.

Figure E-1 Connections Between Spine Switch and Leaf Switches

Description of "Figure E-1 Connections Between Spine Switch and Leaf Switches"

The servers connect to the leaf switches as shown in Figure E-2.

Figure E-2 Connections Between the Servers and the Leaf Switches

Description of "Figure E-2 Connections Between the Servers and the Leaf Switches"

### E.1.2 Cabling the Switches in Two Racks

When you connect multiple racks, remove the seven interswitch connections between leaf switches and the two connections between the leaf switches and the spine switch. From each leaf switch, distribute eight connections over the spine switches in all racks. In multirack environments, the leaf switches inside a rack are not directly interconnected, as shown in Figure E-3.

Figure E-3 shows that each leaf switch in rack 1 connects to the following switches:

- Four connections to its internal spine switch

- Four connections to the spine switch in rack 2

The spine switch in rack 1 connects to the following switches:

- Eight connections to the internal leaf switches (four to each rack 1 switch)

- Eight connections to the leaf switches in rack 2 (four to each rack 2 switch)

Description of "Figure E-3 Connecting Switches Across Two Racks"

### E.1.3 Cabling the Switches in Up to Eight Racks

As the number of racks increases from two to eight, the pattern continues as shown in Figure E-4. Because not all of the racks are shown, not all of the cables are shown either.

Each leaf switch has eight interswitch connections distributed over all spine switches. Each spine switch has 16 interswitch connections distributed over all leaf switches. The leaf switches are not directly interconnected with other leaf switches, and the spine switches are not directly interconnected with the other spine switches.

## E.2 Key to Cabling Table Abbreviations

The following abbreviations are used in the tables:

Abbreviation | Description
--- | ---
Rn | Rack n, where n is the number of the rack, such as R1.
IBn | Unit location in rack, where n is the number, such as IB3.
Pn | InfiniBand port n, where n is port number, such as P8A.

## E.3 Two-Rack Cabling

Note:

- The spine switch is in U1 (IB1) for all racks.
