Standard drive enclosures and drives
Standard drive enclosures and drives are required components of your storage
system configuration.
Each standard drive enclosure feature contains two enclosures.
Each drive set feature contains 16 disk drives or flash drives (SSDs) and is installed
with eight drives in each standard drive-enclosure pair.
The 3.5-inch storage enclosure slots are numbered left to right, and then top to
bottom. The top row of drives is D01 - D04. The second row of drives is D05 -
D08. The third row of drives is D09 - D12.
The 2.5-inch storage enclosure slots are numbered from left to right as slots D01 -
D24. For full SFF (2.5-inch) drive sets, the first installation group populates D01 -
D08 for both standard drive enclosures in the pair. The second installation group
populates D09 - D16. The third installation group populates D17 - D24.
Note: Storage enclosures are installed in the frame from the bottom up.
