Which type of InfiniBand switch is used in a multi-brick XtremIO X2-R array?

Show Suggested Answer Hide Answer
Suggested Answer: A

In a multi-brick XtremIO X2-R array, a 36 port InfiniBand switch is used. This type of switch provides the necessary number of ports to accommodate the connectivity requirements of a multi-brick configuration, ensuring high-speed data transfer and communication between the bricks and other components of the storage array1.

The InfiniBand switch plays a crucial role in the XtremIO X2-R's architecture, as it allows for the interconnection of multiple bricks, which collectively contribute to the array's performance and scalability. The 36 port switch ensures that there are enough ports available for current use and potential future expansion1.

Wait, are we sure it's the 36 port? Seems a bit high.

Definitely not the 12 port switch, that's too small.

I'm a bit stumped on this one. The port count seems like an important detail, but I'm not sure which option is correct. I'll have to make an educated guess and move on.

Based on my understanding of storage arrays, I believe the XtremIO X2-R would likely use a higher port count switch to handle the data throughput, so I'm going to go with option A, the 36 port switch.
