to 4Gbps (< 10Gbps) bandwidth. Again, all connections are further subjected to the Max Connections per
Member and Max Connections per Volume limits and other limiting factors previously mentioned.
3.3 When host ports are slower than PS Series group ports
When the host ports are slower than the PS Series group ports, the number of slower host ports limits the
number of iSCSI connections. This applies with 1Gbps hosts and 10Gbps PS Series group ports. The
PS Series MPIO software makes as many PS Series group port iSCSI connections as possible using available
ports on the host. Each 10Gbps NIC can make multiple connections to maximize the available host
bandwidth. With four 1Gbps host ports, each 10Gbps PS Series group port could use up four 1Gbps ports,
providing up to 4Gbps (< 10Gbps) bandwidth. As before, all connections are further subjected to the max
connections per member, max connections per volume limits and other factors previously mentioned.
