You must cable a new AFF A700 with two DS224C shelves that are fully populated with 15.3 TB SSDs. You want to ensure that the maximum bandwidth between the disks and the controllers is reached.
In this scenario, according to NetApp best practices, which type of cabling should you use?
Quad-path HA is the correct cabling method to ensure maximum bandwidth between the disks and the controllers in a NetApp AFF A700 system with two DS224C shelves fully populated with SSDs. This configuration provides additional path resiliency and effectively doubles the I/O bandwidth to the storage stack, making it ideal for high-performance SSD environments.
correct answer A
A https://community.netapp.com/t5/FAS-and-V-Series-Storage-Systems-Discussions/What-s-Quad-path-used-for/m-p/127941#M7873 While quad-path HA provides additional path resiliency, the main purpose for the additional cabling is to double the I/O bandwidth to the SAS3 storage stack. Configuring the storage stack with quad-path HA and double-wide intrastack connections is optional. All-SSD storage stacks can benefit from the increased bandwidth, especially for for large block (e.g. 64KB) sequential read streaming workloads.
