Host iSCSI configurations
This section provides the following examples of DS5100 and DS5300 host iSCSI
configurations:
v
Single-host, multiple-port configuration, as shown in Figure 83
v
Multiple-host, multiple-port configuration, as shown in Figure 84 on page 120
v
iSCSI and Fibre Channel hosts, multiple-port configuration, as shown in
Figure 85 on page 120
v
Example of an incorrect configuration: Single-host, iSCSI and Fibre Channel, as
shown in Figure 86 on page 121
v
Multiple-host, multiple-port, multiple-switch configuration, as shown in Figure 87
on page 122
Notes:
1. The DS5100 and DS5300 does not support direct connections from the host
systems to the iSCSI ports on the storage subsystem.
2. The DS5100 and DS5300 does not support connections to both iSCSI and Fibre
Channel ports from the same host system.
3. The following illustrations do not accurately represent the controller locations or
port locations in the DS5100 and DS5300. The illustrations are for illustration
purposes only.
Figure 83 shows an example of a multiple port, single-host configuration. A system
that uses multiple iSCSI ports can provide enhanced performance compared to a
single-port iSCSI connection.
Figure 84 on page 120 shows a multiple-host, multiple-port configuration. For
cluster configurations, the following illustration is an example of a multiple-host,
multiple-port, and redundant path and controller configuration. You can replace the
two gigabit Ethernet switches in the illustration with one large gigabit Ethernet
switch that has the required number of ports. Virtual local area network (VLAN) can
also be used to isolate the two iSCSI networks, instead of a single switch.
