Item No	Network Type	Number of Ports Used	Notes
1	Gigabit Ethernet	42	Each N8500 NAS Engine Node uses 2 Gigabit Ethernet ports and each client uses 1 Gigabit Ethernet port both connected to the same 48 port Gigabit Ethernet switch.

Network Configuration Notes

All clients and NAS Engine Nodes connect to a 48 port Gigabit Ethernet switch.

The Ethernet network is configured using the default setting. The jumbo frame were not enabled during the test. All clients and N8500 nodes are connected to a flat network using the same subnet and using the same ethernet switch.

Memory Notes

Each Storage Unit has dual storage controllers that work as an active-active failover pair.

S2300 storage controller provide write cache vault. When power failure is detected, a standby ups will kick in to hold the controller cache contents and controller will flush them back to internal disk. Data in the controller cache is guarantee stable more than 72 hours.

Load Generator Configuration Notes

All filesystems were mounted on all clients, which were connected to the same physical and logical network.

Every client mounts all six filesystems from N8500 Clustered NAS Storage System.The N8500 Engine nodes and clients are partitioned into 3 groups, each group contains 4 cluster Engine nodes and 6 clients.Among each group, 6 clients mount all six filesystems through 8 service IPs exported by the 4 cluster Engine nodes in the same group.
