OmniSwitch 7900-O64 Data Sheet

The Alcatel-Lucent Enterprise OmniSwitch 7900 O64 (OS7900-O64) is a high-performance, low latency switch for high-performance Data Centers.

• Spine Switch
  • Our next-generation, highest-capacity OmniSwitch for Data Center spine use-cases. Breakout options include 2x 400G, 4x 200G and 8x 100G per port, with a maximum of 320 logical ports. This offers reduced cost and power per bit transferred. This type of spine switch helps to scale and enable the migration to 400G leaf connectivity in Data Centers
• AI/ML Clusters
  • Standards-based Ethernet networking for AI/ML training, fine-tuning & inference, leveraging low latency and high-throughput RoCEv2 (Remote Direct Memory Access (RDMA) over Converged Ethernet). This reduces the Job Completion Time (JCT) by using the cognitive routing and congestion management capabilities of the switch. Fully programmable telemetry enables sophisticated on-chip applications for highest network insight and efficient network management
• High-Performance Computing
  • The large number of high-capacity Ethernet ports enables server (and switch) interfaces to transition to higher speeds and denser networks. Enables the virtualisation of compute and storage with VxLAN switching and routing
• Cloud DCI
  • System is ready to support 800G OSFP ZR/ZR+/+6dBm for Cloud DCI scenarios

• OSFP800 switch ports, each supporting 1 x 800 GbE (100G PAM4), or via breakout cables 2 x 400G GbE, 4 x 200 GbE or 8 x 100 GbE
• OSFP800 switch ports also support 1 x 400 GbE (50G PAM4), 1 x 100 GbE (NRZ) and via breakout cables 2 x 200 GbE, 4 x 100 GbE or 8 x 50 GbE
• Up to 30 W power budget per QSFP800 port
• Incorporates Broadcom Tomahawk 5 switch series silicon:
  • Highest Radix: Up to 320 logical ports on a single chip, low latency
  • Cognitive/Adaptive routing and Dynamic Load Balancing (DLB) and Global Load Balancing (GLB)
  • Advanced shared buffering
  • Programmable in-band telemetry
  • Supports end-to-end congestion control
  • Power efficient due to a monolithic 5nm die

• SyncE and PTPv2 support with 1PPS, 10MHz, and ToD connectors on the front panel
• Contains e-fuses to protect transceivers and internal components
• 2 RU form factor
• Supports hot/cold aisles with front-to-back/AFO/port intake airflow SKU and back-to-front/AFI/port exhaust airflow SKU
• All ports on front; PSUs and fans accessible from rear
• Hot-swappable, load-sharing, redundant 3000 W AC/DC PSUs
• 4 Hot-swappable fan modules with 7+1 redundant fans
• Hardware switch pre-loaded with Open Network Install Environment (ONIE) for automated loading of compatible open source and Alcatel-Lucent Enterprise SONiC (ASON) or Alcatel-Lucent Enterprise Operating System (AOS-X) NOS offerings
