What is the switching capacity and latency of the Dell S4810P-AC-R?

The S4810P-AC-R provides 1.28Tbps full-duplex non-blocking switching capacity with 800ns average latency across all ports. This cut-through architecture ensures line-rate L2/L3 forwarding under full load, ideal for low-latency data center applications like HPC and storage fabrics.

How many ports does the S4810P-AC-R support and what speeds?

It features 48 dual-speed 1/10GbE SFP+ ports and 4x 40GbE QSFP+ uplinks, totaling 64x10GbE equivalent with breakout cables. Supports SFP+ transceivers for flexible 1G/10G connectivity in ToR deployments.

Does it support DCB for storage protocols like iSCSI and FCoE?

Yes, with Priority Flow Control (PFC), DCBX, ETS, and low-latency design optimized for iSCSI, FCoE transit, and DCB environments. Provides lossless Ethernet for converged networking without performance degradation.

What stacking and redundancy features are available?

Offers 160Gbps stacking capacity, link aggregation with 16 links per group and 128 groups per stack. Includes hot-swappable redundant PSUs (2x350W) and fans with reverse airflow (AC-R) for high availability.

What L2/L3 scale does the switch provide?

Supports 4K VLANs, 128K MAC addresses, 16K IPv4 routes, 8K IPv6 routes, and 4K IPv4 multicast groups. LAG load balancing on L2/IPv4/IPv6 headers ensures efficient traffic distribution.

What power and environmental specs apply?

Max power 350W AC with 2A at 200-240V draw; operates 0-40°C. Reverse airflow from I/O to PSU optimizes hot/cold aisle cooling in dense racks.
