Configuring iSCSI Host Ports
You can configure the following settings for the iSCSI ports on each MSA2012i
controller module.
Figure 2-2 Host Port Configuration Settings (Common and Controller A)
Settings that are common to all iSCSI ports are:
■ Authentication – Enables or disables use of Challenge-Handshake Authentication
Protocol (CHAP). Disabled by default. To set CHAP names and shared secrets,
see “Configuring iSCSI Login Authentication” on page 45.
■ Link Speed – Sets the link speed either to Automatic, which allows the system to
negotiate the proper speed, or to 1 Gbit/sec. The default is Automatic.
■ Jumbo Frames – Enables or disables support for jumbo frames. A normal frame
can contain 1500 bytes whereas a jumbo frame can contain a maximum of 9000
bytes for larger data transfers. Disabled by default.
Note – Use of jumbo frames can succeed only if jumbo-frame support is enabled on
all network components in the data path.
■ iSNS – Enables or disables registration with a specified Internet Storage Name
Service (iSNS) server, which provides name-to-IP-address mapping. Disabled by
default.
