Chapter 2 Oracle DE2-24 Disk Shelf to 2X4 Port SAS-2 HBAs
Balance the number of disk shelves across the disk chains in your system.
The maximum number of disk shelves supported by each disk chain is six.
Connect each disk chain to two HBAs if available.
Do not mix disks with different capacities or rotation speeds within a single disk shelf.
To maximize performance, use the maximum number of disk chains supported by the controller’s SAS HBAs. For example, four SAS HBAs with eight chains and eight disk shelves will have better performance than two SAS HBAs with four chains and eight disk shelves.
