Cisco UCS C-Series Server Integration with Cisco UCS Manager 4.1 - Cisco UCS C-Series Integration with Cisco UCS Manager [Cisco UCS C-Series Rack-Mount UCS-Managed Server Software] (2024)

This chapter includes the following sections:

Overview

This guide contains information and procedures for installing Cisco UCS Rack Mount Servers for integration with Cisco UCS Manager.

Cisco UCS C-Series Rack-Mount Servers are managed by the built-in standalone software, Cisco Integrated Management Controller (CIMC) . When a C-Series Rack-Mount Server is integrated with Cisco UCS Manager, the Cisco IMC does not manage the server anymore. Instead it is managed with the Cisco UCS Manager software. You will manage the server using the Cisco UCS Manager GUI or Cisco UCS Manager CLI.

Cisco UCS C-Series Server Integration with Cisco UCS Manager 4.1 - Cisco UCS C-Series Integration with Cisco UCS Manager [Cisco UCS C-Series Rack-Mount UCS-Managed Server Software] (1)

Important

If your server is not new, make sure to reset the Cisco IMC to factory default settings before integrating the server with Cisco UCS Manager. See Server Utilities chapter in Cisco UCS C-Series Integrated Management Controller GUI Configuration Guide for your release to reset the server to factory default settings.

You can integrate Cisco UCS C-Series Rack-Mount Servers with Cisco UCS Manager in either one of the following setup:

Cluster setup: Using two Fabric Interconnects (FIs) or two FIs with two Fabric Extenders (FEXes) to connect the C-Series Rack-Mount Server.
Non-cluster setup: Using a single Fabric Interconnect or one FI with one FEX to connect the C-Series Rack-Mount Server. Cisco does not recommend operating UCS domains in Non-Cluster mode because of lack of resiliency. Complete domain outage is expected during routine maintenance upgrades.

Note

For Cisco UCS C-Series Rack-Mount Servers integration with Cisco UCS Manager, Cisco VIC adapters can only be connected to Cisco UCS Fabric Interconnects and not to third-party switches.

For Cisco UCS S-Series Rack-Mount Servers integration with Cisco UCS Manager, see the Cisco UCS S3260 Server Integration with Cisco UCS Manager guide in your specific release.

Integrating C-Series Rack Mount Server with Cisco UCS Manager

Cisco UCS Manager provides three connectivity modes for Cisco UCS C-Series Rack-Mount Server management. The following are the connectivity modes:

Direct Connect Mode: In this mode, a Cisco UCS VIC from a C-Series Rack-Mount Server connects directly to the Fabric Interconnect. Both management and data traffic pass through from the VIC to FI and vice versa.
SingleConnect (Sideband): In this mode, a Cisco UCS VIC from a C-Series Rack-Mount Server connects to FEX and then the Fabric Interconnect. Both management and data traffic pass from VIC to FEX and FI.
Dual-wire Management (Shared LOM): In this mode, shared LAN on the Motherboard (LOM) port from a C-Series Rack-Mount Server connects to FEX for the management traffic. Cisco UCS VIC connects to the FI for the data traffic.

Note

Cisco UCS C125 M5 Serversdo not contain any LOM ports.

The general prerequisites for Dual-wire integration with Cisco UCS Manager are built into the C-Series Rack-Mount Server CIMC release 1.4(6) or later. If you want to use the SingleConnect or direct connect modes you must have the following:

Cisco UCS VIC 1225 Virtual Interface Card
Cisco UCS VIC 1227 (MLOM)
Cisco UCS VIC 1225T Virtual Interface Card
Cisco UCS VIC 1227T (MLOM)
Cisco UCS VIC 1387 (MLOM)
Cisco UCS VIC 1385
Cisco UCS VIC 1455 (supported in M5 and M6 Servers)
Cisco UCS VIC 1457 (MLOM) (supported only in C220 M5 and C240 M5 servers)
Cisco UCS VIC 1495 (supported in M5 and M6 Servers)
Cisco UCS VIC 1497 (MLOM) (supported only in C220 M5 and C240 M5 servers)

Note

For latest support matrix, refer Release Notes for Cisco UCS Manager, Release 4.2.

Cisco UCS VIC 1467 or 1477 Series adapters cannot be used with Cisco UCS 6200 Series Fabric Interconnects.
Cisco UCS C460 M4 Servers, Cisco UCS C125 M5 Servers, Cisco UCS C480 M5 Servers, and Cisco UCS C480 M5 ML Servers do not support MLOM adapters.

The following table lists the C-Series Rack-Mount Servers and supported management options:

Note

Dual-Wire Management is supported only with Cisco VIC adapters and not with third-party adapters.

Table 1. Supported Management Options
Servers	SingleConnect	Direct Connect Mode	Dual-wire Management
Cisco UCS C22 M3 Server	Yes	Yes	Yes
Cisco UCS C24 M3 Server	Yes	Yes	Yes
Cisco UCS C220 M3 Server	Yes	Yes	Yes
Cisco UCS C240 M3 Server	Yes	Yes	Yes
Cisco UCS C420 M3 Server	Yes	Yes	Yes
Cisco UCS C220 M4 Server	Yes	Yes	Yes
Cisco UCS C240 M4 Server	Yes	Yes	Yes
Cisco UCS C460 M4 Server	Yes	Yes	Yes
Cisco UCS C240 SD M5 Server	Yes	Yes	Yes
C480 M5 and C480 M5 ML servers	Yes	Yes	Yes
Cisco UCS C125 M5 Server	Yes	Yes	No

Based on your server model and CIMC version, you can use either one of these three integration options to connect the rack server with Cisco UCS Manager.

Cisco UCS Manager runs within the fabric interconnect (FI). With earlier Cisco UCS Manager releases, you need to use Fabric Extenders to connect the C-series server with the Fabric Interconnect to enable management with Cisco UCS Manager. You can directly connect the server adapter with the Fabric Interconnect without using the Fabric Extender.

Hardware Maintenance

Replacing servers and certain adapter cards requires that the server be decommissioned and recommissioned. See the decommissioning a Rack-Mount server and recommissioning a Rack-Mount Server sections in the appropriate Cisco UCS Manager Configuration Guide.

FEX Connection Mode and Discovery

You can connect the FEX to the FI in two ways. Cisco UCS Manager FI discovers the FEX based on the FEX/Chassis discovery mode. The FEX connection modes are:

Hard-Pinning mode: The server facing FEX ports are pinned to the connected uplink ports when the FEX is discovered. Cisco UCS Manager pins the server-facing ports to the uplink ports based on the number of acknowledged uplink ports. After the pinning, if you add a new uplink or delete an existing uplink, you must manually acknowledge the FEX to apply the changes.
Port-Channel mode: Port-Channel mode does not have pinning. A single port channel works as the uplink to all server-facing ports. And all uplink ports are members of this single port channel. If one of the uplink ports goes down, the traffic is automatically distributed to another available uplink port.

In port-channel mode, when you cable between FEX and the FI, the available virtual interface (VIF) namespace varies, depending on where the uplinks are connected to the FI ports:

When port-channel uplinks from the FEX are connected only within a set of eight ports managed by a single chip, Cisco UCS Manager maximizes the number of VIFs used in service profiles deployed on the servers.
If uplink connections are distributed across ports managed by separate chips, the VIF count is decreased. For example, if you connect seven members of the port channel to ports 1–7, but the eighth member to port 9, this port channel can only support VIFs as though it had one member.

Note

Beginning with Cisco UCS Manager release 4.2, Cisco Nexus N9K-C93180YC-FX3 Fabric Extender supports Cisco UCS VIC 15428, VIC 1455, VIC1457, and VIC 1467 adapters in 25G connection. Supported adapters can be used in mixed configurations.
The maximum number of connections supported from the N9K-C93180YC-FX3 FEX to the Fabric Interconnect is 16.

For more information on FEX discovery policies and port-channel allocation, see the appropriate Cisco UCS Manager Configuration Guide.

Note

Dual-wire management is not supported on the following:

Nexus 93180YC-FX3 in the FEX mode.
Cisco UCS C125 M5 Servers

Note

Different generation VIC adapters are not supported in a single server. For example, if a server has two VIC cards, both these VIC adapters should be either 1400 series or 1300 series or 1200 series. Cisco UCS 15000 Series VIC adapters can be mixed with 1400 series VIC adapters in M6 rack servers. For example, the VIC 15428 MLOM could be used along with 1455/1495 VIC adapter in an M6 rack-server.

Note

For rack server and adapter compatibility, see the respective rack server spec sheet. For connectivity options with Cisco UCS Manager, see Configuration Guides.

Cisco UCS Manager Upgrade Consideration

Beginning with Cisco UCS Manager 3.2(2b) release, UCS Manager does not allow provisioning any vNICs or vHBAs on adapters not listed in in Table 1.

Network Topology and Supported Cables

The following image is a graphical representation of the over-all network topology supported in the C-Series server integration with Cisco UCS Manager.

For more information on server, Cisco VIC and FEX/IOM compatibility, refer Cisco UCS Fabric Interconnect Server Compatibility Matrix - Release 4.2(3) section in Release Notes for Cisco UCS Manager, Release 4.2.

Note

In Cisco UCS Manager, Cisco UCS 6332 and 6332-16UP Fabric Interconnects are supported. Cisco UCS 6324 Fabric Interconnect is not supported. For Cisco UCS 6200 Fabric Interconnects, the Cisco UCS C220 M6 and C240 M6 servers are not supported in Cisco UCS Manager even if VIC 1455 or 1457 are used.

The thick blue line represents a 40 Gigabit Ethernet connection, the thin line represents a 10 Gigabit Ethernet connection. 40 Gigabit Ethernet connections are supported on the Cisco VIC 1385, 1387, 1477, , 1495, and 1497 adapters. 10 Gigabit Ethernet connections are supported on the Cisco VIC 1225, 1227 1385, 1387, 1455, 1457, and 1467 adapters. 25 Gigabit Ethernet connections are supported only on the Cisco VIC 1455, 1457, and 1467.

For the 10 Gigabit Ethernet, the following cables are used:

4x10 Breakout Small Form-Factor Pluggable (SFP) cables
4x10 Active Optical (OAC) cables
10G Small Form-Factor Pluggable (SFP) cable that uses the Qualified Security Assessor (QSA) module

For the 25 Gigabit Ethernet, the following cables are used:

25G SFP 28

Note

While using Cisco VIC 1385 and 1387 in a 10G connection you would a require a 40G to 10G QSFP convertor and you cannot use the 4x10 Breakout Small Form-Factor Pluggable (SFP) cables or 4x10 Active Optical (OAC) cables. Break-out is not supported from VIC when connecting towards FI or FEX. Break-out cables are supported from FI towards VIC 1225/1227 and VIC 1455/1457.

Supported FlexFlash Configuration

Some Cisco UCS C-Series Rack-Mount Servers support an internal Cisco FlexFlash Secure Digital (SD) memory card for storage of server software tools and utilities. FlexFlash is disabled by default. You can enable FlexFlash in a local disk policy used in a service profile.

Note

Cisco UCS C-Series standalone servers with Cisco FlexFlash SD memory cards configured in Utility mode are not supported in the Cisco UCS Manager Integrated mode.

After upgrading CIMC if you are unable to install Cisco FlexFlash, apply the scrub policy before configuring the FlexFlash SD cards.

The FlexFlash SD cards can also be scrubbed using the format SD cards option, if the controller supports the same.
