Overview of Oracle ZFS Storage Appliance Racked System ZS9-2 HE with All-Flash/Mixed Configurations

All-Flash/Mixed configurations take advantage of Oracle Storage Drive Enclosure DE3-24P high-performance disk shelves and are available in a base cabinet, or a base cabinet with up to three expansion cabinets for some configurations. Six base cabinet options are offered in a total of 35 possible system configurations, and all base cabinet options contain two Oracle ZFS Storage ZS9-2 HE controllers.

Expansion cabinets can contain one or both of these disk shelf types:

• Oracle Storage Drive Enclosure DE3-24C

• Oracle Storage Drive Enclosure DE3-12C

The total number of disk shelves cannot exceed the available rack space.

Note:

Oracle ZFS Storage Appliance Racked System ZS9-2, which has preset configurations, can be upgraded in the field to any supported configuration for Oracle ZFS Storage ZS9-2. 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.

Oracle ZFS Storage Appliance Racked System ZS9-2 HE maximum performance configurations feature up to eight Oracle Storage Drive Enclosure DE3-24P disk shelves in the base cabinet. The disk shelves are configured as one single shelf per chain to obtain maximum performance. Depending on the number of chains in the base cabinet, Oracle ZFS Storage Appliance Racked System ZS9-2 HE maximum performance configurations can have up to three expansion cabinets.
