Overview of ZS7-2 HE Racked System Capacity Configurations
Capacity configurations take advantage of high-capacity disk shelves and are available in a base cabinet, or a base cabinet with up to three expansion cabinets. Two ZS7-2 controllers and up to 39 disk shelves can be supported, as shown in the following table.
|
Each ZS7-2 HE capacity base cabinet comprises 1, 2, 4, 6, 8, or 9 DE3-24C disk shelves. Each expansion cabinet comprises 2, 4, 5 (half rack), 6, 8, or 10 DE3-24C disk shelves. A maximum of 39 disk shelves can be accommodated with one base cabinet and three expansion cabinets.
Each ZS7-2 HE controller has four SAS HBA cards. Clustered ZS7-2 HE controllers support a high-availability configuration consisting of:
-
Up to nine disk shelves in the base cabinet configured in two, four, or eight chains, and
-
Up to three expansion cabinets, each cabinet supporting two chains with a maximum of 5 disk shelves per disk chain, for a total of 10 disk shelves for one expansion cabinet, 20 disk shelves for two expansion cabinets, or 30 disk shelves for three expansion cabinets.
The cabinets are self-contained and pre-cabled following the required cabling methodology. Pre-racked system cabling tables and diagrams, which can also be used for planning future system expansion, are provided in the section Cabling Tables and Diagrams for ZS7-2 HE Racked System Capacity Configurations.
Each cabinet contains 42 rack units (RUs), with RU01 on the bottom. Each ZS7-2 controller occupies two rack units, and its location is referenced by the bottommost rack unit number. The top controller is referred to as Controller 1 and is located in RU20 in the base cabinet, and the bottom controller is Controller 0 in RU17. The following figure shows the slot number for each HBA card, as well as the port numbers in each card.

Each DE3-24C disk shelf occupies four rack units, and disk shelves are normally installed from the bottom of the base cabinet to the top for stability. Because the ZS7-2 HE controller occupies two rack units, the base cabinet contains a filler panel above each controller so that the cabinet layout is similar to prior offerings of Oracle racked systems with three-rack-unit controllers. It also allows for better serviceability access and cabling through the rear cable management arm (CMA). As shown in the following figure, the DE3-24C disk shelf has two I/O Modules (IOMs) with four ports each. In all cabling configurations, Port 1 and Port 3 are never used.

Cabling Tables and Diagrams for ZS7-2 HE Racked System Capacity Configurations
The following table describes the locations and port connections for two controllers and nine disk shelves in the base cabinet, using 3-meter optical SAS cables. The first disk shelf is located in RU01, and each disk shelf has two IOMs.
The following tables are for configurations of two chains in the base cabinet and two chains per expansion cabinet, therefore allowing a maximum of 39 disk shelves.

The following table describes the locations and port connections for 10 disk shelves in Expansion Cabinet 1, using 6-meter optical SAS cables. The first disk shelf is located in RU01, and each disk shelf has two IOMs. Expansion Cabinet 1 supports disk shelves 10 through 19.

The following table describes the locations and port connections for 10 disk shelves in Expansion Cabinet 2, using 6-meter optical SAS cables. The first disk shelf is located in RU01, and each disk shelf has two IOMs. Expansion Cabinet 2 supports disk shelves 20 through 29.

The following diagrams illustrate how pre-racked systems are cabled, as well as how to expand your system in the future. The legend for each diagram is as follows:
-
A hollow circle indicates the cable connection to the top IOM (IOM 1).
-
A solid circle indicates the cable connection to the bottom IOM (IOM 0).
