In this example, because only port A0 supports management (MA0), only Server 1 (which is connected

to port A0) is able to perform management and conﬁguration tasks. In addition, because each of the

two targets is conﬁ gured to use a portal group tied to a different MSA iSCSI storage port, access to the

targets is limited to initiators that use the IP address of that storage port.

Known limitations of this example

This example allows more than one server to access the MSA1510i storage, but has the following

limita

tions:

• In direct-connect conﬁgurations, only the server physically connected to Port A0 can manage the

MSA1510i.

• In dir

ect-connect conﬁgurations, a maximum of two servers can access the MSA1510i.

• In single-controller conﬁgurations, no failover path is available.

Basic conﬁguration 2

This examples introduces the following more advanced concepts to a standard-shipping, single-controller

MSA1510i:

• The MSA1510i is connected to a Gigabit Ethernet switch instead of directly to the server.

• Four servers (initiators) are logically connected to the MSA1510i storage through the switch.

• MSA1510i management port MA0 shares the same LAN as the storage ports, allowing all four servers

to access the MSA1510i for management tasks.

• Four storage LUNs are deﬁned and mapped to two targets, which are conﬁgured to use portal groups

tied to the different MSA1510i storage ports.

• With four LUNs, two targets, and four initiators, Access Control Lists (ACLs) are used to control access

to the mapped LUNs and prevent unwanted or simultaneous access by more than one initiator. If
