What is the switching capacity and port configuration of HPE 880645-001?

The HPE 880645-001 SN2100M provides 3.2Tbps full-duplex switching capacity across 16 QSFP28 ports at 100GbE (8 active ports standard, upgradeable to 16 via Q2M94AAE license). This non-blocking architecture supports wire-speed forwarding with dynamic shared buffers for lossless performance in high-density fabrics.

What Layer 2 features does the SN2100M support?

Layer 2 features include STP/RSTP/PVRST, VLAN trunks (IEEE 802.1Q), LACP (IEEE 802.3ad), LLDP/CDP, storm control, and IPv6 neighbor discovery. QoS supports CoS/DSCP classification, DWRR/Strict Priority scheduling, Link PAUSE, and ECN for optimized traffic management.

Is the HPE 880645-001 suitable for storage fabrics?

Yes, designed for storage fabrics with FCoE support, low-latency 100GbE, and lossless Ethernet via priority flow control. Ideal for NVMe-oF deployments connecting servers to all-flash arrays in data centers requiring high-throughput storage networking.

What are the physical dimensions and power redundancy options?

Dimensions are 1.72 x 7.87 x 20 inches (4.39 x 20 x 50.8 cm), weight 10 lbs (4.53 kg). Features redundant hot-swappable power supplies and fan units for 99.999% uptime in mission-critical environments.

What software is required and how is it upgradable?

Requires ONYX and ONIE operating systems. Upgradability via internal flash memory for seamless OS/firmware updates. Optional HPE SN2100M 100GbE 8p Upgrade E-LTU (Q2M94AAE) unlocks additional ports.

What security features are included?

Security includes L2-L4 ACLs with IP/EP tables, CPU protection via hardware rate limiting, 802.1x authentication, and Kernel Address Space Randomization. Provides DoS control and authorized device access for secure data center operations.

Product overview

The HPE StoreFabric SN2100M 880645-001 is a high-performance 100GbE switch engineered for demanding data center environments. Featuring 16 QSFP28 ports (8 active, expandable via license Q2M94AAE), it provides 3.2Tbps full-duplex switching capacity with ultra-low latency and wire-speed performance. Its compact 1U half-width rack-mountable form factor (1.72 x 7.87 x 20 inches, 10 lbs) enables dense deployments, pairing two units per 1U rack space. Redundant hot-swappable power supplies and fans ensure high availability for mission-critical operations. Layer 2 capabilities include STP/RSTP, VLANs, LACP, QoS with DWRR/Strict Priority, ACLs for L2-L4 security, and dynamic shared buffers for lossless Ethernet. Supports ONYX and ONIE OS with flash upgradability. Optimized for storage fabrics, HPC clusters, and cloud infrastructures, it handles high-volume east-west traffic, FCoE, and multi-protocol environments while minimizing power consumption and operational complexity.
