Physical installation planning
Before you set up your system environment, you must verify that the prerequisite conditions for the
system are met.
This information applies to the supported hardware components. Answer the following questions before
you start the installation process:
• Does your physical site meet the environment requirements for your system?
The system requires the physical site to meet the environment requirements. For detailed guidelines
about site preparation and physical planning, see the Site preparation and physical planning document.
• Do you have adequate rack space for your hardware?
The system requires two Electronic Industries Alliance (EIA) units for each IBM Elastic Storage System
3200.
• Do the power circuits that you are planning to use have sufcient capacity and the correct sockets for
your installation?
– A clearly visible and accessible emergency power off switch is required.
– For redundancy, two independent power circuits are required. One circuit connects to each power
supply in each enclosure.
• Have you provided appropriate connectivity by preparing your environment?
The appropriate power requirements for each power supply unit are provided. For more information, see
“Power requirements for each power supply (two per enclosure)” on page 31.
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
IBM Spectrum Scale needs to be installed on the host server before it is connected to IBM Elastic Storage
System 3200. IBM Spectrum Scale provides the high-performance scale-out clustering capabilities. For a
list of supported host type and OS, see IBM Spectrum 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 Elastic Storage System 3200 GUI also
provides a Directed Maintenance Procedure (DMP) for drive replacement.
• A command-line interface (CLI) that uses Secure Shell (SSH).
