Connecting management hosts over an Ethernet network
The management host manages MSA storage systems out-of-band over an Ethernet network.
1. Connect an RJ-45 Ethernet cable to the network management port on each controller module.
2. Connect the other end of each Ethernet cable to a network that your management host can access (preferably on
the same subnet).
3. Set the network port IP addresses. For more information, see
.
For the sake of system security, do not unnecessarily expose the controller module network port to an external network
connection.
NOTE Connections to this device must be made with shielded cables—grounded at both ends—with metallic RFI/EMI
connector hoods, in order to maintain compliance with FCC Rules and Regulations.
NOTE Access via HTTPS and SSH is enabled by default, and access via HTTP and Telnet is disabled by default. See
the Storage Management Guide for more information about suggested protocols.
Connecting two storage systems to replicate volumes
Remote Snap replication is a licensed feature for disaster-recovery. This feature performs asynchronous replication of
block-level data from a volume in a primary system to a volume in a secondary system by creating an internal snapshot
of the primary volume, and copying the changes to the data since the last replication to the secondary system via FC or
iSCSI links.
The two associated volumes form a replication set, and only the primary volume (source of data) can be mapped for
access by a server. Both systems must be licensed to use Remote Snap, and must be connected through switches to the
same fabric or network (no direct attach). The server accessing the replication set must be connected to the primary
system. If the primary system goes offline, a connected server can access the replicated data from the secondary
system.
Replication configuration possibilities are many, and can be cabled—in switch attach fashion—to support MSA
2060/2062 FC Storage and MSA1060 FC Storage systems or MSA 2060/2062 iSCSI Storage and MSA 1060 iSCSI Storage
