Overview

Overview

Cisco Application Policy Infrastructure Controller (APIC) release 5.3(1) added support for the Cisco APIC Server M4 and L4.

Cisco APIC Server M4 and L4 (APIC-SERVER-M4 and APIC-SERVER-L4)—Small form-factor (SFF) drives, with 10-drive HD back-plane front panel configuration.

  • Front-loading drive bays 1—10 support 2.5-inch SAS/SATA drives.

  • Optionally, front-loading drive bays 1 to 4 support 2.5-inch NVMe SSDs (with optional front NVMe cables.)

Considerations and Restrictions

The Cisco Application Policy Infrastructure Controller (APIC) Server M4 and L4 (APIC-SERVER-M4 and APIC-SERVER-L4) has the following consideratios and restrictions:

  • The role of the Dual 1-Gb/10-Gb Ethernet ports (LAN1 and LAN2) in previous Cisco APIC Generations is now moved to the mLOM card and Ports available on that card.

  • The mLom numbering doesn’t matter, APIC software creates a bond interface automatically.

  • There are two disks on the front panel, one of them serving as backup:

    • 1.6TB NVME in slot 1

    • 480GB SSD in slot 5


    Note

    There is also an internal 240G SSD boot disk.

External Features

This topic shows the external features of the server versions.
