The exhibit displays the Synchronous Replication dashboard in Pure1. The question asks to identify the array that replicated the most data, which corresponds to the array with the highest replication throughput. The "Throughput" column shows the rate of data transfer.

By examining this column, we can see that two arrays, dogfood-cheesewheel and dogfood-chuckwagon, both have a throughput of 1.1 GB/s. This is the highest value in the table, greater than the 1.0 GB/s throughput for the other arrays. Therefore, both dogfood-cheesewheel and dogfood-chuckwagon replicated the most data during this period.

C. dogfood-couch: This array's replication throughput is 1.0 GB/s, which is lower than the maximum observed throughput of 1.1 GB/s.

D. dogfood-elk: This array's replication throughput is 1.0 GB/s, which is lower than the maximum observed throughput of 1.1 GB/s.

1. Pure Storage Pure1 Manage User Guide: In the section "Monitoring Performance," the "Replication" tab is described. It details the key performance indicators for replication, including "Throughput," which is defined as the rate of data being replicated between arrays, measured in bytes per second. The exhibit directly reflects this monitoring capability. (Reference: Pure1 Manage User Guide, Section: Analytics > Performance > Replication).

2. Pure Storage FlashArray Best Practices: ActiveCluster: This technical report discusses monitoring for ActiveCluster, Pure's synchronous replication solution. It emphasizes tracking performance metrics like throughput to ensure replication health and performance. The "Throughput" metric shown in the Pure1 exhibit is the primary indicator of the volume of data being replicated. (Reference: FlashArray™ Best Practices: ActiveCluster, Document: TR-180804-01, Section: "Monitoring ActiveCluster").
