HPEQ2S18B

SN6650B 32 Gb Fibre Channel Switch- 48-Port Managed (Options Enabled)

The HPEQ2S18B (SN6650B) is a rack-mounted Fibre Channel Switch offering 48 active 32 Gb/s SFP+ ports, plusoptional activation of up to 96 ports via Ports-on-Demand (PoD). It is designed for enterprise SAN and NVMe-over-FC storage fabrics, delivering 32 Gb/s FC auto-sensing compatibility with legacy 16/8/4 Gb systems. With up to 4 Tb/s aggregate bandwidth, ultra-low latency (< 780 ns), and frame throughput up to 566 million frames/sec (~100 M IOPS), it caters to high-performance data center workloads like flash/NVMe storage, backup, and cloud applications. Software support includes HPEPower Pack+ SAN management tools for automation, analytics, and REST API access. ([turn0search0], [turn0search2], [turn0search8])

Features

This 2U managed switch features 48 short-wave SFP+ ports onboard (via SKU Q9V95C), with optional Port-On-Demand kits allowing activation of up to 96 active ports including QSFP+ (4×32 Gb breakout) connections for increased fabric density ([turn0search0], [turn0search4]). The system provides 4 Tb/s switching capacity, delivered through cut-through hardware for predictable sub-microsecond latency across storage workloads. It thoroughly supports NVMe/FC fabrics and provides analytics with VM-level granularity, I/O insight, and in-flight encryption/compression up to 384 Gbps/192 Gbps. ([turn0search0], [turn0search2]) Advanced RAS features like frame-level diagnostics, redundant power/fan designs, and fabric resiliency mechanisms improve uptime in mission-critical environments. HPEPower Pack+ software adds automation via Ansible, REST APIs, and support for I/O Insight and VM Insight×delivering deep visibility and orchestration for modern SAN deployments.

Advanced Options

Backward compatibility across Fibre Channel standards (32/16/10/8/4 Gb) ensures seamless fabric upgrades. The switch integrates with common storage arrays like HPE3PAR, Nimble, and MSA, supporting zoning, WWN management, and fabric fabric features. CLI and GUI management options include SSH, SNMP v3, and integration with HPESANnav or third-party orchestration platforms.The SN6650B distinguishes itself with ultra-low latency (< 780 ns) and high throughput, well-suited for latency-sensitive flash and NVMe storage fabrics. Despite heavy traffic, frame loss is minimized via cut-through switching, and I/O insight features enable real-time health monitoring and analytics. ([turn0search0])

Reliability & Performance

Highly scalable via PoD licensing, the switch can scale from 48 to 96 ports×including QSFP+ breakout uplinks×without hardware modification. HPEPower Pack+ software supports VM-level visibility, I/O instrumentation, REST APIs, and automation workflows via Ansible. This enables rapid provisioning and fine-tuning of storage fabrics. ([turn0search0]) The design includes redundant hot-swappable fans and power supplies, enterprise-grade fault detection, and secure firmware failover. Compatibility across FC generations ensures backward support for ongoing infrastructure. Management interfaces support secure operations via SSH, SNMP v3, CLI, GUI dashboards, and SMI-S. With built-in diagnostics, encryption, and compression, the switch improves bandwidth efficiency while maintaining operational visibility. ([turn0search0], [turn0search14])
