Expansion Cabinet Configurations for Oracle ZFS Storage Appliance Racked System ZS9-2 HE Performance Configurations

Oracle ZFS Storage Appliance Racked System ZS9-2 HE performance configurations support multiple cabinets that allow for expansion of up to 30 additional Oracle Storage Drive Enclosure DE3-24C disk shelves or up to 60 additional Oracle Storage Drive Enclosure DE3-12C disk shelves.

Each expansion cabinet can contain one or both of these disk shelf types:

  • Oracle Storage Drive Enclosure DE3-24C: Up to 10 disk shelves. Also offered in a “half-rack” option.

  • Oracle Storage Drive Enclosure DE3-12C: Up to 20 disk shelves.

For any configuration, the total number of disk shelves cannot exceed the available rack space.

Note:

Not all base cabinet configurations support expansion cabinets.

The expansion cabinet installation follows a balanced-chain installation where the chain on the bottom of the cabinet takes the first disk shelf pair, and the second chain on the top half takes the second pair. The alternating manner of a balanced chain installation distributes SSDs and follows the load-priority methodology.

The number of expansion cabinets supported is dependent on the number of chains remaining in the Oracle ZFS Storage Appliance Racked System ZS9-2 HE base cabinet. Each Oracle ZFS Storage Appliance Racked System ZS9-2 HE expansion cabinet requires two chains to support a full expansion cabinet. Also, a total of four SAS-3 HBA ports (two HBA ports for each chain) are required for each expansion cabinet.

The following diagrams illustrate the cabling of Oracle ZFS Storage Appliance Racked System ZS9-2 HE expansion cabinet configurations with Oracle Storage Drive Enclosure DE3-24C disk shelves. 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).

Note:

The base cabinet can contain all Oracle Storage Drive Enclosure DE3-24P (HDD) disk shelves, or all Oracle Storage Drive Enclosure DE3-24P All-Flash (SSD) disk shelves, or a mix of Oracle Storage Drive Enclosure DE3-24C/DE3-12C and DE3-24P disk shelves, as described in All-Flash/Mixed Configurations for Oracle ZFS Storage Appliance Racked System ZS9-2 HE.
