Single Server Dual SIOC Connectivity
The S3260 Storage Server operates either in Single Server Single SIOC mode or Single Server Dual SIOC mode. In single server single SIOC mode, the data path from the second SIOC is unused. The second SIOC is used for management redundancy only, if a VIC installed in the second SIOC.
In single server dual SIOC mode, the data path from both SIOCs is provided to the single server. This allows users to use dual VICs or third party adapters (NIC or HBA) for data, or a combination of both. Only the VIC or dedicated management port can provide server management. When third party adapters are used, they are for the host data path only. In this mode:
Effective with this release, the S3260 storage server supports a single server with dual connectivity, which is based on these two factors:
-
The PCIe between the server board and the SIOC card is connected using BIOS.
-
The CMC controls the correct association of the server ID with the virtual network interfaces it creates.
This features allows you to configure a new single server dual VIC chassis property on the Cisco IMC by enabling it or disabling it using the web UI or command line interface.
When using a VIC in the SIOC, a specific PCI connectivity is enabled on the VIC. The CMC uses the single server dual VIC property along with the current chassis hardware configuration to identify the server ID property to be specified when you create a virtual network interface in either of the dual SIOC VICs. The VIC configuration page on the web UI displays the read-only attribute of the Server ID to which the VIC is PCIe linked, and this is used by the host server for the virtual network interface traffic.
Configuring Single Server Dual SIOC Connectivity
Before you begin
-
You must log in with admin privileges to perform this task.
-
The chassis must have a single server and two SIOCs.
Procedure
Step 1 |
In the Navigation pane, click the Chassis menu. |
Step 2 |
In the Chassis menu, click Summary. |
Step 3 |
In the Chassis Properties area of the Chassis Summary pane, from the Server SIOC Connectivity field, select Single Server Single SIOC or Single Server Dual SIOC. If you have a chassis with a single server and dual SIOCs, the Server SIOC Connectivity field displays Single Server Dual SIOC. |
Step 4 |
Click Save Changes. This configures the server for dual or single connectivity. |
