Overview

Introduction

Cisco Intersight Infrastructure Services (IIS) enable the streamlined deployment, monitoring, management, and support of physical and virtual infrastructure. IIS supports Cisco Unified Computing System™ (UCS) servers, HyperFlex™ Hyperconverged Infrastructure (HCI), and third-party devices. In addition, IIS provides the following advanced management and support capabilities along with global visibility of infrastructure health and status.

Intersight Managed Mode (IMM) is a new IIS architecture that manages the UCS Fabric Interconnected systems through a Redfish-based standard model. IMM unifies the capabilities of the UCS Systems and the cloud-based flexibility of Intersight, thus unifying the management experience for the standalone and Fabric Interconnect attached systems.

New Hardware Support in 4.2(1e)

Cisco UCS X9508 Chassis

The Cisco UCS X-Series Modular System begins with the Cisco UCS X9508 Chassis engineered to be adaptable and future ready. With a midplane-free design, I/O connectivity for the X9508 chassis is accomplished with frontloading, vertically oriented compute nodes intersecting with horizontally oriented I/O connectivity modules in the rear of the chassis. A unified Ethernet fabric is supplied with the Cisco UCS 9108 Intelligent Fabric Modules.

  • 7-Rack-Unit (7RU) chassis has 8x front-facing flexible slots. These can house a combination of compute nodes and a pool of future I/O resources that may include GPU accelerators, disk storage, and nonvolatile memory.

  • 2x Cisco UCS 9108 Intelligent Fabric Modules (IFMs) at the top of the chassis that connect the chassis to upstream Cisco UCS 6400 Series Fabric Interconnects. Each IFM features:

    • Up to 100 Gbps of unified fabric connectivity per compute node

    • 8x 25-Gbps SFP28 uplink ports.

  • Six 2800W Power Supply Units (PSUs) provide 54V power to the chassis with N, N+1, and N+N redundancy.

  • Efficient, 4x100mm, dual counter-rotating fans deliver industry-leading airflow and power efficiency.

CSCwd37309

In a UCS X-Series Chassis, using the fan UCSX-9508-FAN, an alert is seen stating "[Chassis fan module] has a critical speed threshold condition". This behavior may be seen on multiple chassis and may occur on different fan modules. A fault gets raised and then gets cleared on its own. The issue is observed during LOW fan speed conditions. If the fault persists and does not clear on its own, physically re-seat the fan. If the fault persists even after re-seating, reach out to Cisco TAC as it could potentially indicate a separate problem.

CSCwd52370

After upgrading the firmware of the Fabric Interconnect in UCSB-5108-AC2 chassis with UCS-IOM-2408, connection to Intersight is lost.

Port flaps cause the CMC to unset its chassis information, which removes the useful information from /var/isconfig. When chassis info is again set, the CMC DC may not re-read the /var/isconfig file after it is again populated with its data, causing the CMC to be disconnected from Intersight.

Restart CMC DC (/etc/init.d/dc restart)

In a setup equipped with Cisco UCS 6400 series FI connected to Cisco UCS C-Series servers using Cisco VIC 1457/1455/1467, ports on the FI may go to error-disabled state with errDisabledExcessportIn reason after a link flap.

Flap the FI port connected to the Cisco UCS C-Series servers.

4.2(2a)

CSCwd90187

In a setup equipped with Cisco UCS 6536 FI, port goes to Link not connected status when QSFP-100G-DR/FR-S is replaced with QSFP-100G-CUxM under the following conditions:

  • 100G interface

  • Interface is configured with FEC Auto

  • Interface was using QSFP-100G-FR, QSFP-100G-DR transceivers

    Interface now uses QSFP-100G-CUxM, where CUxM refers to CU1M, CU2M, and so on.

There are two workarounds for this issue:

  • Perform the following steps:

    1. Insert an optic or AOC transceiver that does not have FEC capability. For example, QSFP-100G-SR or QSFP-100G-AOC3M on the interface.

    2. Remove the transceiver in Step 1.

    3. Re-insert passive copper cable.

  • Reboot the FI.
