Description

The Arista DCS-7388X5-64DR-F is a high-performance modular data center switch designed for hyperscale cloud, AI, and machine learning environments. This system bundle includes the 7388X5 chassis with 64 x 400G QSFP-DD ports, delivering 25.6Tbps of throughput and up to 10.66 Bpps forwarding capacity in a compact 4RU form factor. Built on a single high-capacity packet processor, it offers ultra-low latency as low as 825ns in cut-through mode, advanced Layer 2/Layer 3 features, and flexible configuration options for leaf or spine deployment in large-scale networks.

Features

Layer 2 switching: IEEE 802.1Q VLAN tagging, LACP, STP/RSTP/MSTP, MLAG
- Layer 3 routing: BGP, OSPF, IS-IS, static routing, multicast (PIM, IGMP)
- VXLAN overlay: BGP-EVPN, VXLAN routing and bridging (with FLX license)
- Advanced traffic management: hierarchical QoS, ECN, WRED, traffic shaping
- Low-latency cut-through switching with 825ns port-to-port latency
- 114 MB shared packet buffer for superior burst absorption
- Arista Latency Analyzer (LANZ) for real-time congestion monitoring
- Zero Touch Provisioning (ZTP) for automated deployment
- CloudVision integration for network-wide visibility and automation
- IEEE 1588v2 PTP for precision timing synchronization
- Telemetry streaming and programmability (OpenConfig, gNMI, gRPC)
- Hot-swappable power supplies and fan modules for high availability
- Modular design with removable switch card and I/O modules
- Front-to-rear airflow for efficient data center cooling
- Support for 10G to 400G pluggable optics and DAC/AOC cables

FAQs

Q: What is included in the DCS-7388X5-64DR-F system bundle?
A: The system bundle includes the 7388 chassis, 64 x 400G QSFP-DD interface modules, 2 x redundant AC power supplies, supervisor module with SSD, 7388X5-SC switch card, and fan modules configured for front-to-rear airflow.

Q: What deployment scenarios is the 7388X5 Series designed for?
A: The 7388X5 Series is ideal for hyperscale data centers, AI/ML network fabrics, and high-performance computing environments. It can be deployed as either a leaf or spine switch in modern large-scale Clos architectures requiring high-density 200G and 400G connectivity.

Q: Does the 7388X5-64DR-F support flexible port configurations?
A: Yes, the modular architecture with 8 I/O slots supports multiple configurations. While this bundle includes 64 x 400G QSFP-DD ports, the platform can support up to 128 x 200G or 128 x 100G ports depending on the line cards installed, and ports can be broken out to lower speeds using appropriate optics.

Q: What licensing is required for advanced features?
A: The base Arista EOS feature set is included. For advanced routing features like BGP-EVPN and VXLAN, the EOS Flex-route (FLX) Lite license is available. CloudVision automation and visibility features are available through subscription licensing.

Q: What is the warranty coverage for the 7388X5 Series?
A: The Arista 7388X5 switches come with a one-year limited hardware warranty covering parts, repair, or replacement with a 10 business day turnaround. Extended support services including next business day and 4-hour advance hardware replacement are available for purchase.
