Chapter 7 Installing the Level 30R Storage System
Cabling the switch
• Install the switches in their permanent location.
• Provide power to the switches.
• Use CAT5e or CAT6 cables. The maximum cable length is 50 meters for CAT5e
and 100 meters for CAT6.
• Connect cables as follows:
2900 series switch
To the media ports on switch A, make the “A” media (iSCSI) network connection
from each K2 Media Client. Also make four media (iSCSI) connections from K2
Media Server A.
To the media ports on switch B, make the “B” media (iSCSI) network connection
from each K2 Media Client. Also make four media (iSCSI) connections from K2
Media Server B.
To the control ports on switch A, make one connection from each K2 Media Client,
from RAID controller 0, and from the control point PC. Also make the control
network connection and the FTP network connection from K2 Media Server A.
To the control ports on switch B, make the second control connection from each
K2 Media Client, and from RAID controller 1. Also make the control network
connection and the FTP network connection from K2 Media Server B.
If you have other iSCSI clients, such as Aurora Edits, that have just one iSCSI
connection and one control connection, approximately half of the clients should be
connected to switch A and half of the clients should be connected to switch B. In a
failover event, only the clients connected to one of the switches will remain
operational, so make connections accordingly. Connect the client’s iSCSI
connection to one of the media ports on a switch and the client’s control connection
to one of the control ports on the same switch.
Interconnect switch A and switch B with three 1 Gig ISLs.
If you have optional NH1 K2 Media Servers, for each server connect its FTP
network connection and its control network connection to the control ports on the
same switch. Balance servers between switch A and switch B.
If you have optional NH1-10GE K2 Media Servers, for each server connect its 10
