4. You can install the Linux operating system on bare metal systems, or on non-virtualized systems. For
these systems, the operating system runs directly on the Open Power Abstraction Layer (OPAL)
firmware. For more information about installing the Linux operating system on bare metal systems,
see Installing Linux on bare metal systems(http://www.ibm.com/support/knowledgecenter/

Installing drives in the 8001-22C system
Learn how to install storage drives in the IBM Power
®
System S822LC for Big Data (8001-22C) system.
About this task
You can install the following types of drives in the system:
v SATA drives connected to the SATA controller ports on the system backplane
v SAS drives connected to a SAS RAID adapter
v NVMe drives connected to an NVMe adapter
v 3.5-inch drives
v 2.5-inch drives by using an adapter
Drive installation information for the 8001-22C system

(8001-22C) system.
Notes for thermal limitations:
v If the 8001-22C system has no GPUs, the system can support up to twelve 3.5-inch drives. The ambient
temperature must not be more than 35°C (95°F). If all twelve 3.5-inch drives are installed, the system
limits the 10-core POWER8 processor to 234 W and the 8-core POWER8 processor to 204 W.
v Limitation on the number of supported drives if the 8001-22C system has one or two GPU accelerators
(feature code EKAJ or EKAZ):
– If your 8001-22C system with feature code EKB1 or EKB5 has feature code EKAJ or EKAZ, and if
the system has storage adapters (feature codes EKEA or EKEB), the system can support up to eight
3.5-inch drives. The drives must be installed into the bottom two drive bay rows. The drives cannot
be installed into the top drive bay row.
– If your 8001-22C system with feature code EKB1 or EKB5 has feature code EKAJ or EKAZ, but has
no storage adapters, the system can support up to six 3.5-inch drives. The drives must be installed
into the bottom two drive bay rows in the leftmost positions. The drives cannot be installed into the
top drive bay row nor into the rightmost positions.
– The ambient temperature must not be more than 25°C (77°F). Reduce the maximum allowable
dry-bulb temperature 1°C per 175 m above 950 m. IBM recommends a temperature range of 18°C -
27°C (64°F - 80.6°F). The system limits the 8-core POWER8 processor to 240 W.
– The default Linux governor is “on-demand”, which results in the CPU going to turbo frequency
when the workload demands and the power and cooling parameters allow. The CPU can require up
to 250W at turbo frequency and high utilization. For the cases described here which show less than
250W cooling capability, you might see the indicator “Performance Lags” in the system event log,
when running a demanding workload in “on-demand” mode. That means that the maximum turbo
frequency cannot be held all the time.
