iSCSI configurations
The DS5100 and DS5300 supports 1 Gbps iSCSI connectivity. You must determine
how the host systems will connect to the storage subsystem. The illustrations in the
following sections show common iSCSI host system configurations.
The iSCSI ports support IPv4 and IPv6 TCP/IP addresses, CHAP, and iSNS. Use
either Category 5E or Category 6 Ethernet cable types for iSCSI port connections.
A Category 6 Ethernet cable provides optimal performance.
Note:
The minimum DS5100 and DS5300 configuration is eight partitions. The
maximum is 512 partitions. Configuration upgrades are available as upgrade
options. Contact your IBM reseller or marketing representative for more
information.
