Subsystem Connection and Operation

5.1Cabling

i

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.

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.

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.
