Expansion Cabinet Configurations
ZS5-4 Racked System All Flash supports multi-cabinet configurations that allow for expansion of up to 30 additional disk shelves. Each expansion cabinet accommodates a maximum of ten 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 ZS5-4 Racked System All Flash base cabinet. Each ZS5-4 Racked System All Flash 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 describe the cabling of ZS5-4 Racked System All Flash expansion cabinet configurations.
Note - The base cabinet can contain all DE3-24P disk shelves or a mix of DE3-24C and DE3-24P disk shelves, as described in Base Cabinet Configurations.
