IP address allocation and usage
As you plan your installation, you must consider IP address requirements and service access for the
system.
ESS 3000 uses 100GbE/100Gb EDR network for cluster communication and data transport. For IP port
usage requirement, see IBM Spectrum Scale Knowledge Center.
For configuration and management, you must allocate an IP address to the system. This IP address is
referred to as the management IP address. For extra fault tolerance, you can also configure a second IP
address for the second Ethernet port on the node or file module. The storage system also has a
management IP address, which is known as the system IP address. The addresses must be fixed
addresses. If IPv4 and IPv6 are operating concurrently, you must provide an address for each protocol.
Attention: The address for a management IP cannot be the same as the service IP. Using the same
IP address causes communication problems.
Name servers are not used to locate other devices. You must supply the numeric IP address of the device.
To locate a device, the device must have a fixed IP address.
Planning for high availability
IBM Spectrum Scale can provide rack level redundancy and stretched cluster using file system data
replication. AFM-DR can be used for site-level disaster recovery. For more details, see IBM Spectrum
Scale Knowledge Center.
Storage configuration planning
ESS 3000 provides optimal configuration of IBM Spectrum Scale RAID. For further customization, see IBM
Spectrum Scale RAID Administration guide.
Planning your network and storage network
You need to plan to provide the network infrastructure and the storage network infrastructure that your
system requires.
ESS GUI can be configured to provide event notifications.
