Technical Specifications:
  • Board Type: Frontend network processing adapter
  • Interface Protocols: Fibre Channel 8Gb/s / 16Gb/s, iSCSI 1GbE / 10GbE
  • Port Count: 4 frontend ports (configuration-dependent)
  • Bus Interface: PCIe Gen2 ×8
  • Form Factor: Half-height, half-length PCIe standard
  • Operating Voltage: 3.3V / 12V
  • Throughput: FC 8Gb port 800MB/s (unidirectional); FC 16Gb port 1600MB/s; iSCSI 10GbE 1000MB/s
  • Protocol Processing Latency: <50µs
  • Power Consumption: Approximately 20W
Functional Features:
  • Multi-protocol support: Simultaneously supports FC SAN and iSCSI SAN host connectivity
  • Port Trunking and Multipath load balancing
  • QoS: LUN-based bandwidth limiting and priority scheduling
  • Hardware-level FC Zoning isolation support
  • Hardware offload of TCP/IP and FC protocol processing, reducing controller CPU load
Material Composition:
  • PCB: 10-layer high-density interconnect (HDI) substrate
  • Main Chip: Dedicated FC/iSCSI protocol processing ASIC
  • Optical Module Interface: SFP+ cage connectors (FC mode) / RJ45 (iSCSI mode)
Structural Features: Standard half-height, half-length PCIe board. Front panel provides 4 SFP+ optical module slots (FC mode) or RJ45 ports (iSCSI mode). PCIe gold finger backplane connection with internal SAS link. LED indicators display per-port link status.
Working Principle: The NPZA board receives storage I/O requests from the DS3800 controller, encapsulates data into FC frames or iSCSI packets via the onboard ASIC, and transmits them through SFP+ optical modules or RJ45 ports to host HBA cards or iSCSI initiators.
Performance Parameters:
  • FC 8Gb port throughput: 800MB/s unidirectional
  • FC 16Gb port throughput: 1600MB/s unidirectional
  • iSCSI 10GbE throughput: 1000MB/s unidirectional
  • Protocol processing latency: <50µs
  • Power consumption: Approximately 20W
Application Scenarios: Financial transaction systems, medical imaging storage (PACS), large-scale ERP databases, virtualization clusters (VMware/Hyper-V).
Installation Requirements: Install in the designated PCIe slot of the DS3800 controller. For FC mode, install original SFP+ optical modules; for iSCSI mode, use Cat6a or better network cables. Align SFP+ modules with slot orientation markings.
Usage Precautions: Fibre Channel connections must use FC-specific patch cords—never substitute with standard Ethernet cables. Never look directly into SFP+ optical module laser output. Port speed must be negotiated consistently with the peer device (switch/HBA). Firmware upgrades must be executed exclusively through DS3800 Storage Manager.
