Network & Host Connection Topologies
The iSCSI host ports connect to Ethernet network devices and iSCSI initiators that
comply with the IETF iSCSI standard (RFC 3720). Network connection of the iSCSI
ports is flexible. The use of network connecting devices, subnet, Name Servers, or
iSCSI management software can vary from case to case. In the following sections,
configuration diagrams will be provided to illustrate the possible uses of this system
in an iSCSI network.
Note that host NIC ports and the storage system’s iSCSI host ports must be
configured into the same subnet.
Please note the following:
Use the Ethernet management port for management purposes only, i.e.,
Management Software or telnet console. This Ethernet management port is
not used for I/O transactions.
Configurations such as subnet or Virtual LAN can separate iSCSI host links,
decrease overhead, and eliminate the impact of link failure.
Multiple arrays or logical partitions can be created and made available
separately through different IDs or LUN numbers on the host ports. Usually,
a RAID5 logical drive of eight (8) members often brings optimal array
performance.
NOTE
If you are using Microsoft’s software initiator, please de-select the embedded MPIO
function when installing the software, as the MPIO selection creates conflicts with
EonPath driver.
