Base Cabinet Configurations for Oracle ZFS Storage Appliance Racked System ZS5-2 Performance Configurations
Oracle ZFS Storage Appliance Racked System ZS5-2 maximum performance configurations require two SAS-3 HBAs, which provide the maximum of eight ports of SAS-3 HBA connectivity.
The SAS-3 HBA port numbering order is ascending, from bottom (Port 0) to top (Port 3). Both SAS-3 HBA cards and Oracle Storage Drive Enclosure DE3-24 disk shelves use the SFF 8644 connectors.

The Oracle ZFS Storage Appliance Racked System ZS5-2 cabling configurations follow standard cabling methodologies with additional restrictions that allow use of the cable management arm (CMA). They provide a more practical implementation for SSD log device and read cache device matching, and can be configured for maximum or optimal performance.
Any upgrades that change the number of SAS-3 HBA cards, or include more than one cabinet that is not an original Oracle ZFS Storage Appliance Racked System ZS5-2 or not compatible with Oracle ZFS Storage Appliance Racked System ZS5-2 must be re-cabled for that particular configuration. For cabling examples of connecting Oracle Storage Drive Enclosure DE3-24 disk shelves to an Oracle ZFS Storage ZS5-2 controller with 4x4 port SAS-3 HBAs, see Cabling Oracle Storage Drive Enclosure DE3-24 Disk Shelves to Oracle ZFS Storage ZS5-2 Controllers. For SAS cable length guidelines, see Cabinet and Cabling Guidelines.
The cabinets are self-contained and pre-cabled following the required cabling methodology. The following diagrams illustrate how the five base cabinet options are cabled.
