Features

Performance, ease of use, reliability, and expansion capabilities were key considerations in the design of your system. These design features make it possible for the user to customize the system hardware to meet the needs today and provide flexible expansion capabilities for the future.

Chassis features

  • Redundant optional power capabilities

    The chassis supports up to three hot-swap CRPS power supplies, which provide redundancy.
    Important
    • CRPS power supply units in the chassis must have the same vendor, wattage, and part number (or alternate part number).
    • CRPS Premium (CFFv5) power supply units in the chassis must have the same wattage, and part number (or alternate part number).
  • Chassis management

    The chassis midplane with PSoC (Programmable System on Chip) allows monitor and management of nodes and power supply units in the chassis. A chassis caretaker node is selected by the PSoC firmware for chassis management.

    For the management interface, see Lenovo XClarity Controller portal page. In XCC, certain management functions can only be performed by the caretaker node, whereas other functions can be performed by all nodes.
