Iscsi Interface; Setting Iscsi Information - Hitachi AMS 2100 Hardware Manual

iSCSI interface

The AMS 2100/2300 provides 4 iSCSI ports in each base unit (2 per
controller). The iSCSI interface is capable of operating at data transfer
speed of up to 1000 MB/s when the 10G bps iSCSI interface board is
installed.
The AMS 2100/2300 supports iSCSI (1000Base-T). With the HBA for iSCSI,
Generic NIC + Software initiator, and Network Switch, the array can be
located up to 100 meters from the host computer.
with 50/125 um multimode (OM3/OM2) Cable, the AMS2100/AMS2300
subsystem can be located up to 300 (OM3) meters, or 82 (OM2) meters.
For the 1G bps iSCSI, connect the switch based on the 1000BASE-T (full-
duplex). Use the LAN cable with the following types and shapes.
• Cable type: category 5e or category 6
• Connector: RJ-45
For the physical port of the switch to be connected directly with the host and
the iSCSI port of the AMS 2100/2300, do not set the Spanning Tree protocol
function to ON. It may cause communications interference.
For the 10G bps iSCSI, use the following optical cable:
• 50/125 um multimode (OM2) Cable
• 50/125 um multimode (OM3) Cable

Setting iSCSI information

The following iSCSI information is set for iSCSI ports (it is not set for Fibre
Channel ports).
• iSCSI Port IP address
• iSNS Server
• Adding target
• Target option
The host should log into the specified target of AMS2100/AMS2300 in iSCSI,
unlike Fibre Channel. (Refer to the HBA or iSCSI software initiator manuals
for information about logging in to the target.) In some initiators, the
subsequent re-connection will be done automatically.
