3. Core Hardware Architecture & Key Differentiators

Chassis Slot Layout (3RU 19-inch rack, front-to-back cold aisle airflow only)

1. Slot 1: Single full universal hot-swappable I/O line card slot (max one I/O module loaded)
   • Supported I/O density options:
     • N77-F348XP-23: 48×10G SFP+
     • N77-F324FQ-25: 24×40G QSFP+
     • N77-F312CK-26: 12×100G QSFP28 (max 12×100G ports total chassis)

2. Slot 2: Half-slot Supervisor slot with pre-installed N77-SUP2E (no second supervisor slot built into chassis)

Rear Redundant Subsystems (Pre-integrated in bundle)

1. Dual 3000W AC power supply bays with two PSUs preloaded (1+1 N+1 power redundancy)
2. Single integrated multi-fan variable-speed fan tray (factory included with chassis)
3. No external rear crossbar fabric modules — distributed fabric ASICs embedded inside supervisor and I/O line cards (simplified maintenance, fewer spare parts)

Critical Advantages vs larger Nexus 7706/7710 chassis

1. Ultra-compact 3RU rack footprint for small pod top-of-row core aggregation
2. Embedded distributed fabric design eliminates costly external crossbar modules
3. Pre-bundled single SUP2E + dual AC power to reduce separate component ordering
4. Unified Nexus 7700 Gen3 I/O module compatibility, interchangeable with all 7700 family chassis
5. Complete converged LAN+SAN hardware offload: Lossless PFC/DCBX FCoE, FC-NVMe low-latency tunneling, FICON zSystems storage integration

High-Availability Design

• Power: Dual 3kW AC PSUs, hot-swappable OIR replacement without power cycle
• Cooling: Single integrated fan tray; single fan failure triggers SNMP alert, chassis remains operational for tray swap
• Control plane: Single SUP2E active by default; full HA failover requires pairing a second N77-C7702-S2E-AC as vPC peer switch
• Fault isolation: VDC virtual multi-tenant logical switch partitioning + VSAN storage fabric segmentation to contain broadcast/storage faults
• NPV/NPIV FCoE edge mode offloads Fibre Channel host registration to upstream MDS SAN directors to reduce control-plane overhead
• Full OIR hot-swap for all FRUs (power supplies, fan tray, supervisor, I/O line card) with zero traffic interruption

4. Hardware Performance Specifications

1. Full non-blocking distributed fabric aggregate bandwidth: 1.32 Tbps full-duplex

4. Maximum VDC virtual logical switches: 4 independent multi-tenant partitions
5. Port-channel limit: 1024 logical trunks, up to 16 physical ports per PortChannel
6. Native hardware offload feature set:
   • Lossless FCoE stack: PFC, DCBX, VNTag, FC-NVMe tunneling

6. Typical Deployment Scenarios

1. Small virtualized data center pod core aggregation: Compact 3RU form factor as top-of-row core, single 100G F3 line card delivers 12×100G uplinks to leaf FEX extenders and all-flash FCoE storage arrays, VDC partitions separate production/test/backup workloads.
2. Medium enterprise campus edge converged LAN/SAN switch: Interconnects remote building Nexus switches via OTV cross-DC tunnels, built-in FCIP hardware offload provides asynchronous disaster recovery replication between primary and DR data centers.
3. Small-to-medium service provider multi-tenant PoP edge gateway: VDC multi-tenant logical switch isolation separates independent enterprise customer LAN/SAN fabrics on a single physical bundle, unused I/O slot reserved for future port count expansion.
4. Financial/mainframe zSystems storage core: Native FCoE + FICON compatibility enables long-distance FCIP tape backup replication, dual AC power + single SUP2E HA paired with a second N77-C7702-S2E-AC for full redundant fabric.
5. Legacy Nexus 5000 FCoE switch migration upgrade: Backward compatible with existing 10G SFP transceivers, unlocks 40G/100G high-density port expansion and modern NX-OS OTV/LISP automation workflows.
