This chapter includes the following sections:
Cisco UCS Manager 3.1 supports an option to connect the C-Series Rack-Mount Server directly to the Fabric Interconnects. You do not need the Fabric Extenders. This option enables Cisco UCS Manager to manage the C-Series Rack-Mount Servers using a single cable for both management traffic and data traffic.
(注) |
After connecting the server with the FI, when the server is discovered, make sure to update the C-Series software bundle available for Cisco UCS Manager, release 3.1. While using Cisco VIC 1385 and 1387 in a 10G connection you would a require a 40G to 10G QSFP convertor but you cannot use the 4x10 Breakout Small Form-Factor Pluggable (SFP) cables and 4x10 Active Optical (OAC) cables. |
When you use direct connect mode, all Cisco UCS Managed adapters must be connected to the server ports on the Fabric Interconnects. Make sure you have server firmware as listed in the Requirements for Direct Connect Mode Integration with Cisco UCS Manager 3.1. If not, upgrade your server firmware before integrating the server with Cisco UCS Manager. See Upgrading the C-Series Server Firmware.
For the maximum number of virtual interfaces allowed on each adapter in the server that is directly connected to the Fabric Interconnect, see
Requirements for Cluster Setup
You must have the following items to create a direct connect integration for C-Series Rack-Mount Server with Cisco UCS Manager in cluster setup:
A Cisco UCS system that is running Cisco UCS Manager release 3.1.

For the Cisco UCS 1225T and 1227T cards:Cisco UCS 1225, Cisco UCS 1225T, Cisco UCS 1227T , Cisco UCS 1227, Cisco UCS 1385, and Cisco UCS 1387 VICs also support direct-connect. If you are using Cisco UCS VIC for direct-connect, make sure the card is inserted in one of the slots as described in the following table:

Two Cisco UCS 6200 Series or 6300 Series FIs. The ports must be configured as server ports.
At least two 10-Gb Small Form-Factor Pluggable (SFP) cables for one card.
If you are integrating the server in a non-cluster setup, along with the Cisco UCS Manager and C-series rack mount server, you need the following components :
When establishing the physical connection for the C-Series Rack-Mount Server in the Cisco UCS Domain, you must specify the connection mode and management policy in Cisco UCS Manager GUI or Cisco UCS Manager CLI. The management policy is global to all connected C-Series Rack-Mount Servers. The connection mode determines the rack server discovery in Cisco UCS Manager. Direct connect supports only sideband connectivity
You can specify either one of the following connection policies for the rack servers:
Auto-acknowledged: This is the recommended and default connection mode for the C-Series Rack-Mount Server. If the connection mode is auto-acknowledged, immediately after establishing the physical connection, Cisco UCS Manager discovers the rack server and starts managing the server based on the specified management policy.
User-acknowledged: If the connection mode is user-acknowledged, after establishing the physical connection, you must manually acknowledge the connection and specify the connection mode in the Cisco UCS Manager GUI or Cisco UCS Manager CLI to begin the discovery. Cisco UCS Manager does not begin the C-Series Rack-Mount Server discovery until you specify the connection mode.
(注) |
When rack servers are discovered and are managed by Cisco UCS Manager, if you want to change the existing connection mode for one C-Series Rack-Mount Server, you have to decommission the server, re-commission it and specify the new connection mode. Only then Cisco UCS Manager can discover the server in the new connection mode. |
Make sure the server CIMC is set to factory default settings to integrate with Cisco UCS Manager.
Make sure the FI ports are configured as server ports. If they are not, reconfigure the ports as server ports using the Cisco UCS Manager GUI.
Before you connect the server, make sure the Cisco UCS VIC is installed in the correct slot for integration with Cisco UCS Manager. If the card is not installed in the correct slot, you cannot enable the direct connect management for the server.
ステップ 1 | Install the server in the rack. See the Install and Upgrade Guide for the server that you are using. The install guides are available at the following url: Install and Upgrade Guides. |
ステップ 2 | Configure the server ports on the FI. |
ステップ 3 |
Connect the paths from Cisco UCS VIC adapter to the server ports on the FIs.
|
ステップ 4 | Attach a power cord to each power supply in your server, and then attach the power cord to a grounded AC power outlet. |
Server discovery begins when power is applied.

To connect the C-Series server with a UCS domain in a non-cluster setup, complete the same steps described in Connecting the C-Series Server with Cisco UCS Domain in Cluster Setup. Instead of using two FIs to connect two cables as in cluster setup, you need to connect only one FI and one cable to the adapter.
The following image show the cabling configuration for Cisco UCS Manager integration with the server. The path shown in gold carry both management and data traffic.

Before performing the migration procedure, on the Cisco UCS Manager GUI, Global Policies page, make sure the Rack Discovery Policy and Rack Management Connection Policies are set to the defaults such as,Immediate and Auto Acknowledge. This will make sure after connecting the server directly to the FI, the server is discovered immediately and Cisco UCS Manager starts managing the server without waiting for your interaction.
注意 |
Migrating from SingleConnect FEX connectivity to direct connect is a disruptive process. Make sure you do this during a scheduled outage window. You might need 15 to 20 minutes to complete this procedure. |
After the server reboots, you can resume normal operations.
Before performing the migration procedure, on the Cisco UCS Manager GUI, Global Policies page, make sure the Rack Discovery Policy and Rack Management Connection Policies are set to the defaults such as,Immediate and Auto Acknowledge. This will make sure after connecting the server directly to the FI, the server is discovered immediately and Cisco UCS Manager starts managing the server without waiting for your interaction.
To enable direct connect mode to a server connected in dual-wire management mode, you will need to change the adapter. Changing the adapter may impact the PCIe numbering on a bare metal Windows system. If you had Adapters listed in the OS, after you change them they will be Adapter 3 and 4. If you are using static addressing, you will need to remove the previous adapters from the server. For more information, see http://support.microsoft.com/kb/269155
Recommission the server from Cisco UCS Manager GUI. After the recommission is complete, the server is ready for operation and you can apply service profiles to the server.
You can manage and monitor all rack-mount servers that have been integrated with a Cisco UCS domain through Cisco UCS Manager. After the integration, you will perform all rack-mount server management tasks only through the service profiles from Cisco UCS Manager GUI or Cisco UCS Manager CLI. The C-Series Rack-Mount Server Cisco IMC is not accessible when you start managing the server with Cisco UCS Manager.
Cisco UCS Manager provides information, errors, and faults for each rack-mount server that it has discovered.
For more information on managing C-Series Rack-Mount Servers from Cisco UCS Manager, see the chapter on Managing Rack-Mount Servers in your release specific Cisco UCS Manager Configuration Guide.
When you manage a Cisco UCS C-Series server with Cisco UCS Manager software, a UCS Manager service profile is associated with the server. If you want to revert a C-Series server to standalone mode (so that it can be managed by CIMC software), you must do the following actions in UCS Manager:
