Management ports requirements
The management ports are connected to systems that are used for managing the
XIV system through the IBM XIV Storage Management GUI and IBM XIV
command-line interface (XCLI). These ports can also be used for sending e-mail
notifications and SNMP traps about event alerts.
To ensure redundancy in case of interface-module failure, the IBM XIV Storage
System is managed through three IP addresses over Ethernet interfaces. Each IP
address is handled by a different interface module. The IBM XIV Storage
Management GUI and XCLI must be configured with all three IP addresses that
are defined for the XIV system. Management functions can be performed through
any of the IP addresses. These addresses can be accessed simultaneously by
multiple clients. Users must configure the IBM XIV Storage Management GUI or
XCLI for the set of IP addresses that are defined for the specific XIV system.
To be resilient to a network failure, ensure that the network equipment that
provides management communication is protected by an uninterruptible power
supply.
IP configuration
For each of the three management ports, the customer or technical assistant must
provide the following information to the IBM service representative before the
installation is started:
v IP address of the port
v Net mask
v Default IP gateway
v Maximum transmission unit (MTU)
Note: All management IP interfaces must be connected to the same subnet and use
the same network mask, gateway, and MTU.
In addition, provide the following system-level IP information:
v IP address of the primary and secondary DNS servers
v IP address or DNS names of the SNMP manager, if required
v IP addresses or DNS names of the SMTP servers
Protocols
The XIV system is managed through dedicated management ports that are running
TCP/IP over an Ethernet connection. Management is carried out through the
following protocols:
v The XIV system communicates with key servers using the KMIP protocol over
TCP port 5696 (if the encryption feature is enabled).
v Proprietary protocols are used to manage the XIV system from the IBM XIV
Storage Management GUI and IBM XIV command-line interface (XCLI). This
management communication is over TCP port 7778. The XIV GUI and XCLI act
as the client and initiate the connection. The XIV system acts as the server. All
traffic over this port is encrypted through the Secure Sockets Layer (SSL)
protocol.
v The XIV system responds to SNMP requests when sending replies to SNMP
managers.
