B Appendix – Topology and configuration detail
For clients, multiple VMware ESXi 5.01 servers were configured. Three of the servers were connected to
the back-end SAN switches (and to SAN storage), while the others were connected to the front-end client
LAN switches. On each ESXi server, VMs that ran Linux were created. For both the 1 Gb and 10 Gb test
scenarios, there were 16 clients for block testing and 16 clients for file tests.

The ESXi servers consisted of three Dell PowerEdge R610 servers for the block I/O clients and three Dell
PowerEdge R710 servers for the file I/O clients. For the 1Gb (FS7600) tests, we used the onboard 1 GbE
network ports for management connectivity, and then each server also had a pair of quad-port 1 GbE
network cards. For the 10Gb (FS7610) tests, we used the onboard 1 GbE network ports for management
connectivity, and then each server also had a pair of dual-port 10 GbE network cards.

For the 1Gb network, our LAN and SAN switches each consisted of a pair of Dell Force10 S60 switches
with stacking modules. For 10Gb, our LAN and SAN switches each consisted of a pair of Dell Force10
S4810 switches each with two 40 Gb QSFP+ ports configured as a Link Aggregation Group (LAG).
