Overview of Cisco UCS S3260 Architecture
Data Architecture
The data plane architecture has different associations between components than the management plane.
The diagram shown in Figure 1-8 illustrates the following associations for a dual-server system:
• The data bus in server node 1 connects through SIOC 1.
• The data bus in server node 2 connects through SIOC 2.
• Server 1 SSDs 1 and 2 can be controlled by a RAID controller card in server node 1.
• Server 2 SSDs 1 and 2 can be controlled by a RAID controller card in server node 2.

The diagram shown in Figure 1-9 illustrates the following associations for a single-server system:
• The data bus in server node 2 connects through SIOC 2.
• Server 2 SSDs 1 and 2 can be controlled by a RAID controller card in server node 2.
