Overview of Oracle ZFS Storage Appliance Racked System ZS7-2 HE 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 Oracle ZFS Storage ZS7-2 HE controllers and up to 39 disk shelves can be supported, as shown in the following table.

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.

Each Oracle ZFS Storage Appliance Racked System ZS7-2 HE base cabinet comprises 1, 2, 4, 6, 8, or 9 Oracle Storage Drive Enclosure DE3-24C disk shelves. Each expansion cabinet comprises 2, 4, 5 (half rack), 6, 8, or 10 Oracle Storage Drive Enclosure DE3-24C disk shelves. A maximum of 39 disk shelves can be accommodated with one base cabinet and three expansion cabinets.

Each Oracle ZFS Storage ZS7-2 HE controller has four SAS HBA cards. Clustered Oracle ZFS Storage 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 Oracle ZFS Storage Appliance Racked System ZS7-2 HE Capacity Configurations.

Each cabinet contains 42 rack units (RUs), with RU01 on the bottom. Each Oracle ZFS Storage ZS7-2 HE 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 Oracle Storage Drive Enclosure 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 Oracle ZFS Storage 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 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.
