Expansion Cabinet Configurations for Oracle ZFS Storage Appliance Racked System ZS7-2 HE Performance Configurations

Oracle ZFS Storage Appliance Racked System ZS7-2 HE performance configurations support multiple cabinets that allow for expansion of up to 30 additional disk shelves. Each expansion cabinet accommodates a maximum of 10 Oracle Storage Drive Enclosure DE3-24C disk shelves and is also offered in a “half-rack” option.

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 ZS7-2 HE base cabinet. Each Oracle ZFS Storage Appliance Racked System ZS7-2 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 ZS7-2 HE expansion cabinet configurations. 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 and DE3-24P disk shelves, as described in All-Flash/Mixed Configurations for Oracle ZFS Storage Appliance Racked System ZS7-2 HE.
