HPE Q0U61B

SN6600B 32 Gb 48‑Port Fibre Channel Switch (Power Pack+ Version)

The HPE Q0U61B SN6600B is an enterprise-class 1U Fibre Channel Switch  delivering 48 active 32 Gb SFP+ ports plus4 QSFP+ ports (capable of carrying 4×32 Gb each), allowing up to 64 endpoints per chassis. Powered by HPE B‑Series architecture with Power Pack+ SAN management software, this switch is built for storage-intensive environments—such as flash arrays, hyper-scale virtualization, and cloud fabrics—offering high throughput, sub‑microsecond latency (~700 ns), and IO performance up to 566 million frames/sec (≈100 million IOPS Its flexibility to auto-negotiate across FC speeds (4/8/16/32 Gb) and upscale via QSFP+ ports enables future-proof deployment and easy fabric expansion. Suitable for IBM mainframe or SAN fabrics, SN6600B is ideal for enterprise datacenters demanding scalability, performance, and resilience.

Features

The SN6600B (HPE StoreFabric B‑Series) supports up to 48 native SFP+ ports at 32 Gb FC speeds, each capable of backward operations at 16 Gb, 8 Gb, 10 Gb, or 4 Gb depending on host requirements . Additionally, the switch includes four QSFP+ ports—each supporting breakout into four 32 Gb FC links for aggregation or uplinks—enabling total fabric expansion of up to 64 ports within a 1U chassis Equipped with internal redundant hot-swappable power supplies and cooling fans, the switch supports non-stop fabric operations and high availability for enterprise environments. Key features include high-speed cut-through switching with sub-700 ns port-to-port latency, zero frame loss under high throughput, and Power Pack+ SAN management software providing analytics, monitoring, and integrated support for HPE 3PAR environments

Advanced Options

The switch supports advanced SAN protocols including Fabric Shortest Path First (FSPF), ISL trunking, SNS, BB Credit Recovery, RSCN, DPS, and DFP. Management interfaces include CLI, SSH, SNMP v3, HTTP/HTTPS, SMI-S API, and web dashboards via Power Pack+ for fabric visualization and diagnostics Optimized for unpredictable, latency-sensitive SAN workloads, the SN6600B offers guaranteed sub‑microsecond latency at full line rate with no frame loss. Its design targets flash-based storage and high-performance compute fabrics. Fabric features like advanced credit recovery and dynamic path selection ensure traffic resilience and reliability across storage nodes. The Power Pack+ software suite enables proactive health monitoring, ISL performance tracking, and deep insight into SAN behavior—reducing troubleshooting time and improving SLAs
