Unifying Storage, Networking, and Clustering

This Chelsio T520-CR adapter supports Unified Wire functionality, allowing it to handle:

  • High-speed data networking
  • Remote Direct Memory Access (RDMA)
  • iSCSI offloads and FCoE capabilities
  • Network clustering applications

Ideal for Performance-Critical Workloads

Engineered for high-efficiency server deployments, this adapter is best suited for the following scenarios:

  • Data center virtualization
  • Cloud infrastructure hosting
  • Financial trading systems
  • High-performance computing (HPC)
  • Scientific research clusters

Advanced Networking Capabilities

The T520-CR integrates a comprehensive feature set that transforms traditional networking by offering unified wire capabilities. This includes support for:

1. iSCSI Offload

By offloading iSCSI processing to the adapter, the host CPU is freed from heavy storage traffic processing, enhancing system performance and scalability. This is crucial in data-intensive applications such as SAN environments or virtualized storage arrays.

2. Full TCP/IP Offload

TCP Offload Engine (TOE) accelerates data transfer rates by offloading TCP/IP stack processing from the host CPU. This allows for reduced latency, lower CPU utilization, and increased network throughput — critical for cloud data centers and hyper-converged infrastructures.

3. RDMA over Ethernet (iWARP)

RDMA provides ultra-low latency and high throughput by enabling direct memory access from one system’s memory to another without involving the CPU. This function is ideal for HPC (High Performance Computing), real-time trading, and clustered environments.

Hardware Architecture

The Dell JF0FV Chelsio T520-CR is built around Chelsio’s Terminator 5 ASIC — a powerful architecture optimized for networking and storage. The device includes:

Robust PCIe Gen2 x8 Interface

The PCIe Gen2 x8 interface ensures high-speed data transmission between the server and network interface. This bus architecture offers sufficient bandwidth to handle the dual 10GbE ports operating at full line rate.

Dual SFP+ Ports

Equipped with two SFP+ slots, the adapter allows for flexible 10GbE fiber optic connectivity. It supports a range of optical transceivers and DACs (Direct Attach Cables), making it adaptable to different deployment scenarios.

High Reliability Components

Engineered for continuous uptime, the adapter features ECC-protected memory and hardware checksums to ensure data integrity, even under heavy workloads.

Virtualization and Cloud Readiness

Modern enterprise infrastructures increasingly rely on virtualization, and the Dell JF0FV T520-CR is ready to meet this demand with advanced features that include:

SR-IOV Support

Single Root I/O Virtualization (SR-IOV) allows a single adapter to appear as multiple virtual functions (VFs), enabling direct VM access to the network interface. This reduces overhead and significantly improves performance in hypervisor environments.

VMware and Hyper-V Compatibility

Certified drivers are available for VMware ESXi, Microsoft Hyper-V, and other major hypervisors, ensuring seamless integration into existing virtual environments.

Network Partitioning (NPAR)

NPAR divides a single physical port into multiple logical ports, each with its own bandwidth allocation. This is ideal for multi-tenant or converged I/O infrastructures.

Security and Encryption

Security is a paramount concern in any data center. The Chelsio T520-CR addresses this with:

IPsec and TLS Offload

The adapter includes hardware offload capabilities for IPsec and TLS encryption, ensuring secure data transmission without compromising system performance.

IEEE 802.1q VLAN Tagging

Provides enhanced network segmentation and policy enforcement by enabling VLAN tagging for traffic isolation and management.

Energy Efficiency and Thermal Design

Despite its powerful capabilities, the T520-CR is engineered for low power consumption. Advanced power management features include:

Dynamic Power Scaling

Automatically adjusts power usage based on current workload, improving efficiency and lowering operational costs.

Efficient Heat Dissipation

The card’s passive heatsink and thermal design ensure consistent operation under high loads without throttling.
