Subsystem Connection and Operation
5.1
Cabling
Following are the requirements on the type of cables used to connect the subsystem’s iSCSI 
host ports:
Gigabit Ethernet network cables.
Cat6 type cables or better performance types. 
Straight-through Ethernet cables with RJ-45 plugs.
Use of cross-over cables can also automatically be detected and re-routed for a valid con-
nection. 
Connection can be made directly to iSCSI initiators or through Gigabit Ethernet switches, to 
servers equipped with an iSCSI HBA, and then to client stations with a normal NIC or iSCSI 
HBA. The subsystem presents its logical capacity volumes through SCSI-like IDs and LUN’s, 
and these volumes appear as iSCSI targets through the network. 
5.2
Host Connection Topologies
The RAID subsystem provides two Gigabit Ethernet ports. The host-side connection can be 
made as the following:
Directly attached to the VIP X1600 encoder unit
Connection through Ethernet Switch
Network configurations, such as subnet or VLAN settings, can be applied as long as perma-
nent IPs are available with the subsystem’s iSCSI host ports. Automatic assignment methods, 
such as DHCP, are not recommended for configuring the iSCSI connection. RAIDWatch need 
to access the array over standard TCP/IP and RAIDWatch may not recognize an array if port 
IPs have been changed.

NOTICE! 
All cables must be handled with care. Make sure Ethernet cables do not run parallel with 
power cords. To prevent interference within a rack system, the cable routing path must be 
carefully planned and they must not be bent.
