Description

Arista DCS-7300X3-48YC4 48 SFP28 Ports+4 QSFP100 Ports Line Card

Model: Arista DCS-7300X3-48YC4
Type: 48-port 10/25GbE with 4-port 100GbE modular line card
Chassis Compatibility: Part of the Arista 7300X3 series modular switches, compatible with chassis like the 7304, 7308, and 7316.
Use Case: Suitable for leaf and spine architectures in large-scale data centers, high-performance computing (HPC) clusters, and cloud environments.
2. Ports and Interfaces
48 x 10/25GbE SFP28 ports.
Each port supports 10GbE or 25GbE speeds.
4 x 100GbE QSFP28 ports.
Each port supports 100GbE speeds and can be broken out into 4x25GbE or 4x10GbE using breakout cables.
All ports support full wire-speed switching and forwarding.
3. Performance
Total Switching Capacity: 4.8 Tbps (terabits per second) per line card.
Forwarding Rate: 2.4 Bpps (billion packets per second).
Port-to-Port Latency: Low-latency switching optimized for cloud and large-scale data center environments.
Buffer Memory: 32 MB of shared buffer memory, dynamically allocated based on traffic requirements.
4. Layer 2 and Layer 3 Features
Layer 2:
IEEE 802.1Q VLANs with support for up to 4,000 VLANs.
Link Aggregation Control Protocol (LACP) for bundling multiple physical links.
Spanning Tree Protocols (STP, RSTP, MSTP) for network loop prevention.
Jumbo frames up to 9,216 bytes.
Layer 3:
Full support for IPv4 and IPv6 routing.
Routing protocols such as OSPF, BGP, IS-IS, and RIP.
VRF (Virtual Routing and Forwarding) for network segmentation.
Equal-Cost Multi-Path (ECMP) routing for load balancing.
VXLAN (Virtual Extensible LAN) for network virtualization and large-scale Layer 2 bridging.
Advanced IP routing features like PIM-SM, PIM-DM, IGMP, and multicast routing.
5. Quality of Service (QoS)
Traffic Classification: Supports classification based on Layer 2, Layer 3, and Layer 4 headers.
Traffic Shaping: Capabilities for traffic prioritization and bandwidth management.
Scheduling: Supports weighted fair queuing (WFQ), strict priority queuing, and other advanced scheduling algorithms.
Congestion Management: Explicit Congestion Notification (ECN) and Data Center TCP (DCTCP) for congestion control in high-performance environments.
6. Security Features
Access Control Lists (ACLs): Both standard and extended ACLs for traffic filtering and security enforcement.
Port Security: Controls based on MAC addresses to prevent unauthorized devices from connecting.
AAA (Authentication, Authorization, and Accounting): Supports RADIUS and TACACS+ for authentication.
Storm Control: Protection against broadcast, multicast, and unknown unicast traffic storms.
Control Plane Protection (CoPP): Protects the control plane from DoS attacks and unauthorized access.
7. Network Management and Monitoring
Telemetry: Real-time network telemetry for proactive network monitoring and diagnostics.
sFlow: Supports sFlow for traffic analysis and network visibility.
SNMP: Supports SNMP versions 1, 2, and 3 for remote monitoring.
CLI and REST APIs: Offers both command-line interface (CLI) and REST APIs for network configuration and management.
Automation: Supports Ansible, Puppet, Chef, and other automation tools for seamless deployment and management.
8. Power and Cooling
Power Requirements:
Power consumption varies based on traffic and configuration, but the switch is optimized for power efficiency.
Power Supplies: Dual redundant, hot-swappable power supplies are supported in the chassis for high availability.
Cooling: Supports hot-swappable, redundant fan trays with front-to-back or back-to-front airflow options.
9. Environmental Specifications
Operating Temperature: 32°F to 104°F (0°C to 40°C)
Storage Temperature: -40°F to 158°F (-40°C to 70°C)
Operating Humidity: 5% to 95% non-condensing
Cooling and Airflow: Supports hot-swappable fan trays with airflow direction options depending on data center requirements.
10. Chassis Compatibility
Compatible with the following Arista 7300 series chassis:
7304 (4-slot chassis).
7308 (8-slot chassis).
7316 (16-slot chassis).
The line card can be used in various configurations within the chassis to optimize for either spine or leaf roles depending on the architecture.
11. Reliability and Redundancy
Redundancy:
Supports redundant power supplies, fans, and supervisor modules for high availability.
In-Service Software Upgrades (ISSU): Allows software upgrades without traffic disruption, ensuring network uptime.
Hot-Swappable Components: Power supplies, fans, and line cards are all hot-swappable, minimizing downtime.
12. Compliance and Certifications
RoHS: Compliant with the Restriction of Hazardous Substances (RoHS) directive.
Safety Certifications: Complies with UL, CSA, IEC, and other global safety standards.
EMC: Meets international EMC standards for emission and susceptibility, including FCC, CE, and EN certifications.
13. Use Cases
Data Center Leaf-Spine Architecture: Optimized for deployment as either a leaf or spine switch in large-scale cloud and data center environments.
High-Performance Computing (HPC): Ideal for latency-sensitive applications and high-throughput environments.
Cloud Networking: Suitable for cloud-scale network designs with flexible connectivity options for 10GbE, 25GbE, and 100GbE.
