Arista DCS-7358-16C | 7358X4 16-Port 100G Module, up to 8x 200G

Q: Which chassis models are compatible with the DCS-7358-16C module?
A: The DCS-7358-16C is compatible with both the Arista 7358X4 and 7368X4 Series modular chassis. These 4RU systems support up to 8 line card modules and can deliver a total system capacity of 12.8 Tbps with up to 128 ports of 100G or 32 ports of 400G when fully populated.

Q: Can I mix different line card types in the same 7358X4 or 7368X4 chassis?
A: Yes, the 7358X4 and 7368X4 Series support a mix-and-match architecture. You can combine different interface modules including 25G, 100G, 200G, and 400G modules in the same chassis to meet your specific network requirements without oversubscription.

Q: What speeds are supported on the DCS-7358-16C module ports?
A: Each QSFP100 port supports 100GbE by default. The module also supports up to 8 ports of 200GbE mode on alternate ports, as well as 40GbE connectivity for backward compatibility, providing flexibility for evolving network requirements.

Q: Is the DCS-7358-16C hot-swappable for maintenance operations?
A: Yes, the DCS-7358-16C is fully hot-swappable and field-replaceable. Combined with Arista EOS features like live software patching and Stateful Fault Repair, you can perform maintenance and module replacements without network downtime.

Q: What deployment scenarios are ideal for the 7358X4 Series with this module?
A: The 7358X4 Series with DCS-7358-16C modules is optimized for hyperscale cloud data centers, AI/ML workloads, and high-performance computing environments. It is suitable for both leaf and spine tier deployments where high port density, low latency, and flexible interface speeds are required.
