MergePoint Service Processor Manager SP53XX Installer/User Guide
Ethernet ports on the MergePoint SP5324/SP5340 appliance
The MergePoint SP5324/SP5340 appliance has two public Ethernet ports (eth0 and eth1) and 24 or
40 Ethernet private ports. The public ports are used for connecting to the public (or management)
network and the private ports are used for connecting to service processors on the private network.
Therefore, the managed private side of the MergePoint SP manager is isolated from the public side
to ensure security. Access to all connected service processor servers is consolidated through the one
publicly known IP address.
Private Ethernet ports
The MergePoint SP5324/SP5340 appliance is aware of only a single interface to the private
network, priv0, for communicating with the target devices. Packets are sent and received by priv0
through the private Ethernet ports.
Each private Ethernet port may be connected to one or to multiple service processors. For example,
an Ethernet port may be connected to a blade manager with multiple service processors, and in
those cases a single private Ethernet port may require multiple IP addresses.
All communication among private Ethernet ports is blocked unless priv0 is the sending or
receiving port.
Public Ethernet ports
On the public side of the MergePoint SP5324/SP5340 appliance, the primary and secondary
Ethernet ports are referred to as eth0 and eth1.
Failover
Failover is important for high-availability environments where constant accessibility is required to
support mission-critical applications. The secondary Ethernet port on the MergePoint SP5324/
SP5340 appliance can optionally be configured for failover. Failover automatically redirects traffic
from the primary Ethernet port to the secondary Ethernet port should the primary interface fail.
The primary Ethernet port continues to be monitored, and when it starts functioning again, traffic is
then automatically redirected back through the primary Ethernet port. All connection sessions
continue without interruption.
With failover, both the primary and secondary Ethernet ports are assigned a single IP and single
MAC [Ethernet] address. After failover is enabled, the bonded Ethernet interfaces are referred to as
bond0.
Bridge mode
Bridge mode bridges the private Ethernet ports with the public Ethernet ports, allowing traffic to go
through the MergePoint SP5324/SP5340 appliance from a host on the external network to a service
processor on the internal network and vice-versa, with no interference from the MergePoint SP
manager itself.
