Overview of Oracle ZFS Storage Appliance Racked System ZS7-2 MR Capacity Configurations

Capacity configurations take advantage of high-capacity disk shelves and are available in a base cabinet, or a base cabinet with one expansion cabinet. Two Oracle ZFS Storage ZS7-2 MR controllers and up to 19 Oracle Storage Drive Enclosure DE3-24C disk shelves can be supported, as shown in the following table. Note that the total number of disk shelves for the base cabinet and the expansion cabinet together cannot exceed 19.

Note:

Oracle ZFS Storage Appliance Racked System ZS7-2, which has preset configurations, can be upgraded in the field to any supported configuration for Oracle ZFS Storage ZS7-2. For example, you can upgrade the racked system by adding one disk shelf to a two-disk-shelf configuration, adding cabling for the new disk shelf, and then recabling the disk shelves. Thus, three disk shelves are supported, even though the racked system is not offered in a three-disk-shelf configuration. Complex upgrades require extensive planning and recabling.

Table 10-9 Oracle ZFS Storage Appliance Racked System ZS7-2 MR Capacity Configurations Components

Base Cabinet	Expansion Cabinet 1
Up to 9 Oracle Storage Drive Enclosure DE3-24C disk shelves Factory configurations: 1, 2, 4, 6, 8, or 9 Oracle Storage Drive Enclosure DE3-24C disk shelves Two Oracle ZFS Storage ZS7-2 MR controllers	Up to 10 Oracle Storage Drive Enclosure DE3-24C disk shelves Factory configurations: 2, 4, 5, 6, 8, or 10 Oracle Storage Drive Enclosure DE3-24C disk shelves

Each Oracle ZFS Storage ZS7-2 MR controller supports two SAS HBA cards. Two SAS HBA cards must be installed in each Oracle ZFS Storage ZS7-2 MR controller to support disk shelves in the expansion cabinet.

Each Oracle ZFS Storage ZS7-2 MR controller has two SAS HBA cards. Clustered Oracle ZFS Storage ZS7-2 MR controller support a high-availability configuration consisting of:

• Base cabinet: Two chains with four disk shelves in one chain and five disk shelves in the other chain for a total of nine disk shelves, and

• Expansion cabinet: Two chains with five disk shelves in each chain for a total of ten disk shelves.

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 Oracle ZFS Storage Appliance Racked System ZS7-2 MR Capacity Configurations.

Each cabinet contains 42 rack units (RUs), with RU01 on the bottom. Each Oracle ZFS Storage ZS7-2 MR 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; the bottom controller is Controller 0 in RU17. Because the Oracle ZFS Storage ZS7-2 MR controller occupies two rack units, the base cabinet contains a filler panel above each controller so 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). The following figure shows the slot number for each HBA card, as well as the port numbers in each card.

Each Oracle Storage Drive Enclosure DE3-24C disk shelf occupies four rack units, and disk shelves are normally installed from the bottom of the cabinet to the top for stability. As shown in the following figure, the Oracle Storage Drive Enclosure 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.
