Hardware Requirements


Note


The UCS E-Series M6 Servers can be installed in the following Cisco Catalyst 8300 Series Edge platforms:
  • C8300-2N2S-4T2X

  • C8300-2N2S-6T

Note


For details about the E-Series M6 Servers, see the “Hardware Requirements” section in the Hardware Installation Guide for Cisco UCS E-Series M6 Servers .

Software Requirements

The UCS E-Series M6 Servers require three major software systems:

CIMC Firmware

Cisco Integrated Management Controller (CIMC) is a management module, which is built into the motherboard. A dedicated processor, separate from the main server CPU, runs the CIMC firmware. CIMC is the management service for the UCS E-Series M6 Servers. You can use CIMC to access, configure, administer, and monitor the server.

The system ships with a running version of the CIMC firmware. You can update the CIMC firmware, but no initial installation is needed.


Note


The table below lists the minimum CIMC versions required for the UCS E-Series M6 Servers.

Table 1. Minimum CIMC Versions Required

Server Name

CIMC Version

UCS-E1100D-M6

4.11.1


BIOS Firmware

BIOS initializes the hardware in the system, discovers bootable devices, and boots them in the provided sequence. It boots the operating system and configures the hardware for the operating system to use. BIOS manageability features allow you to interact with the hardware and use it. In addition, BIOS provides options to configure the system, manage firmware, and create BIOS error reports.

The system ships with a running version of the BIOS firmware. You can update the BIOS firmware, but no initial installation is needed.

Operating System or Hypervisor

The main server CPU runs on an operating system, or a hypervisor. You can purchase an E-Series M6 Server with a preinstalled hypervisor.

The following hypervisors are supported for CIMC 4.12.1 release:

  • VMware ESXi 7.0U3g

  • RHEL 8.3

GUI Requirements

The UCS E-Series M6 servers GUI is supported on the following browsers:

  • Google Chrome

  • Microsoft Edge

  • Mozilla Firefox

  • Safari

Upgrading to a New Software Release

To upgrade the BIOS or CIMC image on your UCS E-Series M6 server, obtain the package (image) from https://software.cisco.com/download/home, and follow the instructions in chapter “Firmware Management” in the CLI Configuration Guide for UCS E-Series M6 Servers.
