Management network layer

  • Management switches provide OOB management connectivity to all the connected devices, such as Cisco UCS FIs, Cisco ToR switches, management solution components, Dell storage devices, and Dell data protection devices.

    The management network layer of the 3-Tier Platform includes at least one pair of Cisco Nexus 93108TC-FX3P or Cisco Nexus 92348GC-X management switches.

    For systems with more than one pair of Cisco Nexus 93108TC-FX3P or 92348GC-X management switches, use a pair of 9336C-FX2 management aggregation switches to aggregate management traffic.

    • 93108TC-FX3P switch: Provides 100 Mbps, 1 Gbps, or 10 Gbps connectivity to the management interfaces of the 3-Tier Platform components and the management solution components.
    • 92348GC-X switch: Provides 1 Gbps, 10 Gbps, or 25 Gbps connectivity to the management interfaces of the Tier 3 Platform components and the management solution components.

    The following table shows the management network layer components:

    The following components connect to the Cisco Nexus 92348GC-X switches using Cat 6 connections at 100 Mbps, or 1 Gbps:

    • FI management
    • Cisco Nexus 9336C-FX2 switch management aggregation (if present)
    • Cisco MDS SAN switch management
    • Storage array management
    • Data protection appliance connections
    • Management solution servers Cisco IMC
    • Management plane connections for either a single system or multisystem management solution
    • Management solution Dell Unity XT management and iSCSI
    • Management solution configurations using the Cisco Nexus 92348GC-X switch can be single system or multisystem management solutions with a Dell Unity XT 480 array. The array is configured with 25 GbE optical connectivity through the mezzanine adapter:Connects to the Cisco Nexus 92348GC-X switch using SFP28 25 GbE ports.
    • Connects the servers to the Cisco Nexus 92348GC-X switch using QSFP 4 x10 GbE breakout ports.

    The Cisco Nexus 92348GC-X switches uplink to the external network using multimode fiber at 10 Gbps, 25 Gbps, or 40 Gbps.

    If the Cisco Nexus 92348GC-X supports either a single system or multisystem management solution with a Unity XT 480 array that is configured with optical connectivity, the uplink connectivity options are limited to QSFP 10 GbE breakout ports using multimode fiber.

    The Cisco Nexus 92348GC-X management switch supports four fixed 10 Gbps, 25 Gbps SFP28, or two 40 Gbps QSFP28 uplink ports for the management layer.

    Two uplinks are required per management switch.
