Hardware configuration planning

This topic describes the hardware configuration to be used for FPO model and IBM Storage Scale client node in shared storage model.

Table 1. Hardware configuration for FPO model
Configuration	Recommended configuration
Network	At least one 10Gb+ ethernet adapter or IB adapters
Disk	SAS disks, 8~12 disks per node
Memory	100+ GB per node
CPU	8+ logic processors

Note: For X86_64, with hyper thread on (by default), one physical core is mapped to two logic processors. For ppc64le, SMT 4 is recommended and one physical core is mapped to four logic processors.

Table 2. Hardware configuration for IBM Storage Scale client node in shared storage model
Configuration	Recommended configuration
Network	At least one 10 Gb+ ethernet adapter or IB adapters
Disk	SAS disks, ~ 6 disks for shuffle if possible
Memory	100+ GB per node
CPU	8+ logic processors

Note: It is better to take the same hardware configurations for all Hadoop nodes.
