6.4 Redundancy of the Management LAN

6.3.2 Redundancy of external storage
In the PRIMEQUEST 2000 series, redundancy of external storage that stores the user data can be achieved
by the following procedure.
External storage
and
configuration
Outside the Redundancy is possible with a single volume
cabinet: alone because the hardware RAID
External RAID configuration is created with an external
device RAID device.
Also, redundancy of the access path is
made possible by using a multipath
configuration.
Furthermore, redundancy is made possible
by software mirroring configuration using
volumes in multiple RAID cabinet (using
PRIMECLUSTER GDS). If a problem occurs
in one cabinet, the system can continue
running in the other cabinet.
6.4 Redundancy of the Management LAN
The Management LAN is used for connecting between the MMB Web-UI and SVmco. The management
LAN of each partition is connected using a LAN card added in PCI Express slot to which the partition
belongs. This management LAN is connected through MMB user support. The MMB has four external
interface ports.
Two ports are allocated for maintenance, and the other two ports are used for connecting the console units
or connecting nodes between cabinet in the cluster configuration, to create duplex configuration architecture
(duplication).
For details on the management LAN, see '1.3 Management LAN ' in the "PRIMEQUEST 2000 Series
Administration Manual" (C122-E175EN).

Operation LAN Redundancy

This section describes the operational LAN redundancy that applies to the configuration of the operation
system. Configuration of a redundant network or and network interface requires at least two network
interfaces and an optional software for switching these interfaces.
The operation LAN redundancy supported by the PRIMEQUEST 2000 series is as follows.
- Duplication of a transmission path between servers (high-speed switching method)
Depending on the duplex network configuration of the transmission path due to PRIMECLUSTER GLS
(Global Link Services) or the type of communication partner server, the transmission path can be
duplicated by various procedures to achieve high reliability of the entire communication.
For details on the redundancy of operation LAN based on PRIMECLUSTER GLS, see PRIMECLUSTER
Global Link Services Manual (Transmission path duplex functions edition).
- Teaming with Intel PROSet
It is possible to configure a teaming based on Intel PROSet. For more information, see Help in Intel
PROSet.
- Redundancy using bonding
Linux supports redundancy using bonding.
- Redundancy using NIC teaming function
Windows Server 2012/ 2012R2 support redundancy using NIC teaming function that is provided by the
operating system.
Note
There are some precautions on teaming with Intel PROSet (R). For information on the items, see 'G.9 NIC
(Network interface card)' of the "PRIMEQUEST 2000 Series Administration Manual" (C122-E175EN).
