Base Cabinet Configurations for Oracle ZFS Storage Appliance Racked System ZS7-2 MR with All-Flash/Mixed Configurations

Oracle ZFS Storage Appliance Racked System ZS7-2 MR all-flash/mixed configurations have two SAS-3 HBAs in each controller, 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 following figure shows the slot number for each HBA card, as well as the port numbers in each card.


This image shows the Oracle ZFS Storage ZS7-2 MR back panel with HBA slot numbers.

As shown in the following figure, the Oracle Storage Drive Enclosure DE3-24P disk shelf has two I/O modules (IOMs) with four ports each. In all cabling configurations, Port 1 and Port 3 are never used.

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.

The Oracle ZFS Storage Appliance Racked System ZS7-2 MR 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 ZS7-2 MR or not compatible with Oracle ZFS Storage Appliance Racked System ZS7-2 MR 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 ZS7-2 MR controller with 4x4 port SAS-3 HBAs, see Cabling Oracle Storage Drive Enclosure DE3-24 Disk Shelves to Oracle ZFS Storage ZS7-2 Mid-range (MR) 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 six base cabinet options are cabled.

Oracle ZFS Storage Appliance Racked System ZS7-2 MR Performance Configuration:

Four Oracle Storage Drive Enclosure DE3-24P Disk Shelves (maximum performance)


This image shows Oracle ZFS Storage Appliance Racked System ZS7-2 MR with four Oracle Storage Drive Enclosure DE3-24P disk shelves in four chains.

This configuration can have one, two, or four Oracle Storage Drive Enclosure DE3-24P disk shelves utilizing the maximum performance cabling scheme.

Oracle ZFS Storage Appliance Racked System ZS7-2 MR Performance Configuration:

18 Oracle Storage Drive Enclosure DE3-24P Disk Shelves (optimum performance)


This figure shows the Oracle ZFS Storage Appliance Racked System ZS7-2 MR performance configuration with 18 Oracle Storage Drive Enclosure DE3-24P disk shelves in four chains.

Oracle Storage Drive Enclosure DE3-24P disk shelves in this configuration are added in pairs. Any other combination of disk shelves are added by pairs starting at the bottom of the rack. Valid disk shelf count combinations are 2, 4, 6, 8, 10, 12, 14, 16, and 18 disk shelves.
