Non-enclosure (decorative) materials must have a flammability rating of V-1 or better. If glass is used
(such as in rack doors), it must be safety glass. If wood shelves are used in the rack/cabinet, they must
be treated with a UL Listed flame-retardant coating.
• The rack or cabinet configuration must comply with all IBM requirements for "safe to service" (contact
your IBM Installation Planning Representative for assistance in determining if the environment is safe).
There must be no unique maintenance procedures or tools that are required for service.
Elevated service installations, where the products to be serviced are installed between 1.5 m and 3.7 m
(5 ft and 12 ft) above the floor, require the availability of an OSHA- and CSA-approved nonconductive step
ladder or ladders. If a ladder or ladders are required for service, the customer must supply the OSHA- and
CSA- approved nonconductive step ladder (unless other arrangements are made with the local Service
Branch Office). Some products can have rack installation limitations. Refer to the specific enclosure or
product specifications for any restrictions. Products that are installed over 2.9 m (9 ft) above the floor
require a Special Bid to be completed before they can be serviced by IBM service personnel.
For products not intended for rack-mounting to be serviced by IBM, the products and parts that are
replaced as part of that service must not weigh over 11.4 kg (25 lb) Contact your Installation Planning
Representative if in doubt.
There must not be any special education or training that is required for safe servicing of any of the
products that are installed in the racks. Contact your Installation Planning Representative if you are in
doubt.
IP address allocation and usage
As you plan your installation, you must consider IP address requirements and service access for the
system.
IBM Elastic Storage System 3200 uses 100GbE/100Gb EDR/200Gb HDR network for cluster
communication and data transport. For IP port usage requirement, see IBM Spectrum Scale
Documentation.
For configuration and management, you must allocate an IP address to the system. This IP address
is referred to as the management IP address. 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 documentation.
Storage configuration planning
IBM Elastic Storage System 3200 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.
