IBM 6000 - Operating Environment; IP Address Allocation and Usage; Planning Your Network and Storage Network; Planning for High-Speed Network Adapter

Operating environment
To use the system, you must meet the minimum hardware and software requirements and ensure that the
other operating environment criteria are met.
Supported hosts
To access the high-performance scale-out clustering capabilities of the IBM Storage Scale System 6000,
users must rst install a supported IBM Storage Scale license on one or more client nodes (preferably in
a remote cluster). These nodes allow clients to mount the IBM Storage Scale lesystem (or NFS or SMB
protocol export), and run applications to read or write data. For a list of supported client host types and
operating systems, see IBM Storage Scale Frequently Asked Questions
.
User interfaces
The system provides the following user interfaces:
• The management GUI, which is a web-accessible graphical user interface (GUI) that supports flexible
and rapid access to storage management information. The IBM Storage Scale System 6000 GUI also
provides a directed maintenance procedure (DMP) for drive replacement.
• A command-line interface (CLI) that uses Secure Shell (SSH).
IP address allocation and usage
As you plan your installation, you must consider IP address requirements and service access for the
system.
IBM Storage Scale System 6000 uses 100 GbE / 200 GbE / 100 Gb EDR / 200 Gb HDR network for
cluster communication and data transport. For IP port usage requirements, see IBM Storage Scale
Documentation.
Attention:
The address for a management IP cannot be the same as the service IP. Using the same
IP address causes communication problems.
Planning your network and storage network
You need to plan to provide the network infrastructure and the storage network infrastructure that your
system requires.
Planning for high-speed network adapter
Review the prerequisite system requirements and installation considerations before deployment.
It is helpful to be familiar with the following term when you are considering the features of the high-speed
network adapter for these connections.
Remote Direct Memory Access (RDMA)
RDMA is a networking standard that allows the adapters to transfer data directly to or from the
endpoints in a connection without using CPU resources on either of the endpoints. These transfers
occur simultaneously with other system operations and do not impact overall system performance.
When the system performs an I/O operation over an RDMA-based connection, data is sent directly to
the network, which reduces latency and increases the speed of data transfers.
Review the following elements when you are deciding to install the high-speed network adapters:
• The following adapter is available:
– (FC AJZL) CX-6 VPI in PCIe form factor
- InniBand: HDR200 200 Gb / HDR100 100 Gb / EDR 100 Gb
