The sequential read performance as shown in Figure 9 peaks at ~2000MB/s.

6.2. 10 Gigabit Ethernet sequential writes and reads
Results of sequential write and read tests over the 10 Gigabit Ethernet link to the NFS server are shown
in Figure 10 and Figure 11. From the graphs it can be seen that the NSS-HA solution scales well for both
writes and reads. The peak throughput saturates around 1200MB/s which reaches the maximum
capability of the public network that connects the client cluster to the server. Both the 144TB and
288TB configurations exhibit similar performance trends since the network is the limiting factor in this
case and not the number of disks in the solution. Note that for these tests, each client is connected to
the NFS server via a single Gigabit Ethernet link.
