Disk I/O performance is very important for storage arrays, But I/O problems may also come from the network. For example, an Ethernet-based SAN, such as iSCSI or FCoE, may cause network bandwidth bottlenecks. Therefore, configuring storage on an independent application server can simplify potential network congestion problems. Network I/O performance can also respond to the bandwidth-intensive application stream. The bottlenec
