Table 5-7 Create Initiator Screen Settings
Setting Description
Initiator Name Enter the name of the iSCSI initiator you are creating. This name must exactly match
the name defined for the iSCSI initiator to which the xStack Storage Array will connect;
otherwise, the connection will fail.
Password To use Challenge Handshake Authentication Protocol (CHAP) authentication when
connecting to an iSCSI target, type the password that will be used during mutual CHAP
authentication when an initiator authenticates a target. For security, each typed
character appears as an asterisk (*). This setting is optional.
Confirm password If you typed a password, retype the same the same case-sensitive password in this
field. For security, each typed character appears as an asterisk (*).
5.4.3 Working with LAGs and VLANs
The xStack Storage Array manages the data ports on the enclosure's back panel using the concept
of LAG ports. In a simple configuration, a LAG port associates a single Ethernet port (i.e., a
physical data port) with a network portal that defines an IP address.
5.4.3.1 Creating LAGs and VLANs
By default, each physical data port on the xStack Storage Array corresponds to a LAG:
DSN-2100 : The default number of LAGs is eight.
DSN-3400 : The default number of LAGs is one. Since this model has only one data port, it
does not support LAG capabilities.
In the default configuration, each data port corresponds to the LAG port of the same number. For
example, the first LAG port (
LAG 08000000
) corresponds to Ethernet port 0 and to data port 0
on the enclosure's back panel. Similarly,
LAG 08000003
corresponds to Ethernet port 3 and to
physical data port 3. No changes are necessary to use the xStack Storage Array in this
configuration.
Link Aggregation is a way to combine (or “aggregate”) multiple data ports in parallel to act as a
single logical connection with increased bandwidth, and the xStack Storage Array can do this,
too.
Combining two or more data ports increases the overall bandwidth capability between the xStack
Storage Array and your SAN, and creates resilient and redundant links. These capabilities are
suited for demanding applications that run in high-performance environments, such as servers in
enterprises, Web servers, and intranet servers, which can benefit from the high-bandwidth
capabilities of link aggregation.
