Description

Ultra-high-performance 48-port 32 Gbps Fibre Channel module for modern all-flash and NVMe/FC SANs. Delivers true line-rate forwarding across all ports with deep buffers for burst absorption and congestion mitigation. Backward-compatible with 16/8/4 Gbps FC and includes advanced services such as VSANs, QoS, and Inter-VSAN Routing (license).

Features

- 48 x 32G FC ports with full line-rate throughput
- 1.536 Tbps per-module switching capacity
- Supports NVMe/FC for next-generation storage performance
- Deep buffers and congestion controls for consistent latency
- Backward-compatible optics and link speeds

FAQs

Q: Will this work with 16G or 8G Fibre Channel devices?
A: Yes. Ports auto-negotiate to 16/8/4 Gbps for backward compatibility.

Q: Does it support NVMe over Fibre Channel?
A: Yes. NVMe/FC is supported for high-performance, low-latency storage fabrics.

Q: What optics are required?
A: Use 32G FC SFP28 transceivers for full 32G; 16G/8G/4G optics can be used at their native speeds.

Q: Is Inter-VSAN Routing available?
A: Yes. IVR is available with the appropriate NX-OS license.

Q: Which MDS chassis is this for?
A: It is designed for MDS 9700 series director chassis such as the 9706, 9710, and 9718.
