Setting up the Level 2R redundant GigE switches
server B.
To the control ports on switch A, make one control connection from each K2 Media
Client or other iSCSI client, from the RAID storage chassis, and from the control
point PC. Also make the FTP network connection and the control network
connection from media server A.
To the control ports on switch B, make the second control connection from each
K2 Media Client or other iSCSI client. Also make the FTP network connection and
the control network connection from 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 two 10 Gig ISLs.
Refer to “Level 2R system description” on page 96 for a diagram of the complete
system.
Refer to cabling procedures later in this chapter for the GigE connections at each of
the devices of the K2 Storage System.
Also refer to “K2 Ethernet switch description” on page 299 and “Design
considerations for Ethernet switches” on page 376 .
Configuring the GigE switch via serial connection
NOTE: Make sure you check the switch firmware and upgrade if necessary, as
instructed at the end of this procedure.
For redundant systems with two switches, do the following on each switch.
Use a direct console connection to the switch, start a console session, and access the
Switch Setup screen to set the IP address. The following procedure is for the HP
ProCurve switch, which is required for iSCSI traffic. If you are using a non-HP switch
for non-iSCSI traffic, accomplish the same tasks as appropriate. Consult the
documentation that came with the switch for more information.
1. Configure the PC terminal emulator on the control point PC or another PC as a
DEC VT-100 (ANSI) terminal or use a VT-100 terminal, and configure either one
to operate with these settings:
• Baud rate 115200
• 8 data bits, 1 stop bit, no parity, and flow control set to Xon/Xoff
• Also disable (uncheck) the “Use Function, Arrow, and Ctrl Keys for Windows”
option
2. Connect the PC to the switch’s Console Port using the console cable included with
the switch. (If your PC or terminal has a 25-pin serial connector, first attach a 9-pin
to 25-pin straight-through adapter at one end of the console cable.)
