Questions about this item

How long will the 8 GB cache memory on the MR416i-p Gen11 last before it needs replacement?

The 8 GB cache is a solid-state module soldered to the controller and has no user-replaceable battery or capacitor; it is designed to last the service life of the server accessory without scheduled replacement.

What is the first performance limit reached when the x16 lane interface runs at sustained throughput?

The x16 lane PCI interface sets the maximum sustained bandwidth ceiling; once that link is saturated, the controller cannot push data faster regardless of cache size.
