Lenovo 7D8PA003WW Thinksystem DB610S FC SAN Switch

Lenovo 7D8PA003WW ThinkSystem DB610S FC SAN Switch

Overview

The Lenovo ThinkSystem DB610S, part number 7D8PA003WW, is a 1U rack-mount Fibre Channel SAN switch designed for enterprise storage area networks that demand high-density connectivity, consistent throughput, and hardware-enforced security. With 24 SFP+ ports active out of the box and a switching capacity of 28.05 Gbit/s, this is a purpose-built fabric switch for data center environments where storage latency and fabric reliability are non-negotiable.

Unlike general-purpose network switches pressed into SAN duty, the DB610S is engineered specifically for FC fabric workloads — making it a natural fit alongside Lenovo ThinkSystem server and storage infrastructure or as a brand-agnostic fabric layer in mixed-vendor SANs. If you're building or expanding a SAN switching fabric, the 7D8PA003WW gives you a dense, manageable 1U platform without a chassis investment.

Key Features

• 24 Active SFP+ Ports: All 24 SFP+ module slots are populated and active at shipment — no licensing or port-activation fees required to reach full density. For a 24-server or 24-storage-target environment, that means a fully operational fabric from day one without incremental unlock costs that inflate total deployment spend.
• 28.05 Gbps Switching Capacity: The non-blocking switching fabric handles 28.05 Gbps aggregate, which is sufficient to sustain simultaneous full-bandwidth traffic across all 24 ports without internal congestion. In practice, this prevents the fabric from becoming the bottleneck in mixed read/write workloads typical of virtualized storage environments.
• 768,000 Mpps Forwarding Throughput: At 768,000 Mpps, frame forwarding is handled entirely in hardware — no software processing overhead that could introduce latency jitter. For latency-sensitive workloads like all-flash storage arrays or VDI boot storms, deterministic low-latency forwarding is the spec that matters most.
• Dual GbE Management Ports (RJ-45): Two onboard Gigabit Ethernet management ports provide out-of-band access for configuration, monitoring, and firmware updates. Having two management interfaces means you can maintain a dedicated management VLAN without losing access if one uplink fails — a basic but critical resilience feature for production fabrics.
• 802.1X RADIUS, IPSec, SSH, SSL/TLS Security Stack: Hardware-enforced 802.1X port authentication ties into your existing RADIUS infrastructure to prevent unauthorized devices from joining the fabric. IPSec, SSH, and SSL/TLS cover management-plane encryption, so in-flight CLI sessions and API calls are not exposed in plaintext on the management network. ACL support adds a policy layer for granular traffic segmentation.
• Port Mirroring: Inline traffic mirroring lets you non-disruptively feed a network analyzer or IDS without inserting a physical tap or taking the port offline. Useful for performance troubleshooting in production environments where you cannot afford downtime to diagnose a slow-drain device.
• Full-Duplex Operation: All ports operate full duplex, meaning simultaneous transmit and receive at rated line speed with no half-duplex fallback. In a SAN context this is expected, but worth confirming — half-duplex on any fabric segment will immediately degrade throughput and introduce retransmissions under load.
• Multicast Support: Native multicast handling is relevant if your SAN fabric carries replication traffic or if you're running NVMe-oF workloads that use multicast discovery. Without it, you'd be relying on broadcast flooding or manual configuration — both of which create unnecessary fabric noise at scale.
• 1U Rack Form Factor, 10 lb: At 10 lb and a single rack unit, the DB610S fits cleanly into standard 2-post or 4-post racks without requiring a shelf or special mounting hardware. A 24-port FC switch in 1U is compact enough to deploy in edge data closets or co-location cages where rack space is billed by the unit.
• USB 2.0 Console Port: The onboard USB 2.0 port supports out-of-band serial console access, allowing initial configuration and recovery without relying on the management network — important when commissioning a new fabric or recovering from a misconfiguration that breaks network reachability.

Integration and Compatibility

The DB610S integrates into standard FC SAN topologies — edge-to-core, core-to-edge, and collapsed-core — and is compatible with Fibre Channel infrastructure from major storage vendors. The dual GbE management ports support standard SNMP, SSH, and SSL/TLS-based management, which means it can be incorporated into existing NMS platforms (SolarWinds, PRTG, Nagios, and similar) without vendor-specific collectors.

ACL and 802.1X RADIUS support makes this switch compatible with enterprise AAA frameworks, including Microsoft NPS and Cisco ISE, for fabric access control. For environments that require structured SAN zoning and management, the security feature set aligns well with PCI-DSS and SOC 2 network segmentation requirements — though verification against your specific compliance framework is recommended.

The SFP+ form factor is compatible with standard 8G, 16G, and 32G FC SFPs from major optics vendors, providing flexibility when sourcing transceivers for existing cabling plants. Pair the DB610S with a compatible managed upstream switch or core director for redundant fabric designs.

Frequently Asked Questions

Q: How many ports does the Lenovo 7D8PA003WW ship with active?

A: All 24 SFP+ ports are active at shipment — no additional port licenses are required to reach full capacity.

Q: What is the switching capacity of the ThinkSystem DB610S?

A: The DB610S has a switching capacity of 28.05 Gbit/s with a forwarding throughput of 768,000 Mpps, handled entirely in hardware.

Q: Does the 7D8PA003WW support out-of-band management?

A: Yes. The switch includes two GbE RJ-45 management ports and a USB 2.0 console port, supporting SSH, SSL/TLS, and SNMP-based out-of-band management independent of the data plane.

Q: What security protocols does the DB610S support?

A: The switch supports 802.1X RADIUS port authentication, IPSec, SSH, SSL/TLS, ACL-based access control, and port mirroring for traffic inspection. Full-duplex operation is standard on all ports.

Q: What rack space does the 7D8PA003WW require?

A: The DB610S occupies a single rack unit (1U) and weighs 10 lb. It is compatible with standard 2-post and 4-post rack mounting.

Q: Can the DB610S be integrated with third-party AAA or NMS platforms?

A: Yes. 802.1X RADIUS support is compatible with Microsoft NPS, Cisco ISE, and similar RADIUS servers. SSH/SSL/TLS management plane access is compatible with standard NMS platforms supporting SNMP.
