IRQ Assignment Conflicts

12Remove the system-board assembly. See “Removing a System-Board Assembly” on page 170.

13Replace processor 1 with processor 2. See “Installing a Processor” on page 178.

14Repeat step 9 through step 11.

If you have tested both the processors and the problem persists, the system board is faulty. See “Getting Help” on page 343.

Most PCI devices can share an IRQ with another device, but they cannot use an IRQ simultaneously. To avoid this type of conflict, see the documentation for each PCI device for specific IRQ requirements.

C6220 II specifications

The Dell C6220 II is a high-density, highly scalable server designed to meet the demands of data centers and cloud environments. Launched as a successor to the C6220, this model builds on its predecessor's strengths with enhanced performance, flexibility, and energy efficiency. Its compact design allows multiple units to be housed in a single chassis, making it an ideal solution for organizations that require a significant amount of computing power without occupying extensive floor space.

One of the primary features of the Dell C6220 II is its support for Intel Xeon processors. This server can accommodate up to four separate compute nodes within a single 2U chassis, each supporting two CPU sockets. This configuration allows for a substantial amount of processing power, essential for virtualization, cloud computing, and big data applications. The use of the latest Intel technology ensures higher core counts, improved performance per watt, and enhanced capabilities for parallel processing tasks.

The C6220 II offers versatility with its memory support, allowing for up to 24 DIMM slots per compute node. This results in a maximum memory capacity of up to 1.5TB per node, enabling organizations to run large databases and memory-intensive applications efficiently. Additionally, it supports both DDR3 and DDR4 memory, giving users flexibility in terms of performance and cost.

Storage capabilities are another significant aspect of the Dell C6220 II. Each compute node can be configured with multiple hard drives or solid-state drives, allowing for optimal storage configurations. This server is compatible with various RAID configurations to enhance data integrity and availability. Furthermore, the C6220 II includes support for both local and hybrid storage options, which enables organizations to tailor their storage solutions to specific workloads.

Networking is vital for data center operations, and the Dell C6220 II offers robust networking options. The server includes multiple networking ports, which can be configured for redundancy and load balancing, ensuring high availability and performance. This feature is critical for businesses that rely on uninterrupted access to their applications and data.

In terms of energy efficiency, the Dell C6220 II has been designed with advanced cooling technologies to minimize energy consumption while maintaining optimal performance levels. The use of intelligent fans and airflow management contributes to lower operating costs and reduced environmental impact.

In conclusion, the Dell C6220 II is a powerful and flexible server that meets a wide range of business needs. Its ability to handle high workloads, coupled with its scalable design, makes it an excellent choice for modern data centers and cloud environments. Organizations looking for robust performance, efficient storage solutions, and reliable networking should consider the Dell C6220 II as a key component of their IT infrastructure.
