Arista Networks 7124SX 10G SFP Data Center Switch
High performance, ultra-low latency layer 2/3/4 10 Gigabit Ethernet switch.
[7124sx]Details
Ultra-low, Consistent Latency
The 7124SX offers industry-leading sub-500 nanoseconds forwarding latency for both unicast and multicast traffic. The latency characteristics do not change with varying packet size, enabling L3, ACL or mirroring functionality.
Arista EOS
All Arista products including the 7124SX switch run Arista EOS software. The same binary image supports all Arista products, making it easy for network administrators to standardize the operating system across all switches in the data center. A built in SSD is available for advanced logging, data captures and various services that can now be run from the switch.
Arista EOS is a modular switch operating system with a unique state sharing architecture that cleanly separates switch state from protocol processing and application logic. Built on top of a standard Linux kernel, all EOS processes run in their own protected memory space and exchange state through an in-memory database. This multi-process state sharing architecture provides the foundation for in-service-software updates and self-healing resiliency. Several Linux based tools can be run directly on the switch, running on a powerful dual-core x86 CPU subsystem.
Latency Analyzer (LANZ) with Built-in Storage
The 7124SX offers advanced capabilities for latency analysis in a network. Congestion points can be identified and tracked over time. A built-in 50GB SSD is available as an option from the factory. The integrated storage allows for a whole new family of applications that can be run from the network itself. This includes having the switch be a PXE boot server, store syslogs for audit and compliance right on the switch, logging latency trends per queue, capturing and saving data packets via tcpdump and Linux based services such as DHCP and Precision Time Protocol (PTP).
High Availability
The Arista 7124SX switch was designed for high availability from both a software and hardware perspective. Key high availability features include:
- 1+1 hot-swappable power supplies
- Four N+1 hot-swappable fans
- Live patching
- Self healing software with Stateful Fault Repair (SFR)
- Up to 16 10GbE ports per link aggregation group (LAG)
- Multi-chassis LAG for active/active L2 multipathing
- 16-way ECMP routing for load balancing and redundancy
Deterministic, Ultra-Low Latency
The Arista 7124SX is optimized for ultra-low latency, cut-through forwarding. It offers the same low latency characteristics at all packet sizes. The latency does not change even when additional features such as L3, ACL, QoS, Multicast or Port Mirroring are enabled. The 7124SX also forwards packets in cut-through mode at 1GbE speeds at low latency for legacy connections.
