Key Feature for the BR-VDX6940-24Q-AC-F

  • What is the port configuration of the Brocade VDX 6940-36Q base system?
    The system has 24x 40 Gigabit Ethernet QSFP+ ports for network connections.
  • How does the airflow direction in the Brocade VDX 6940-36Q affect its placement in a rack?
    It has a non-port-side (front-to-back) exhaust airflow, meaning it expels air away from the port side, affecting its placement for optimal cooling.
  • What are the available management ports on the VDX 6940-36Q?
    It includes an out-of-band RJ-45 management port, 1x RS-232, and 1x USB port for management.
  • Can the fan modules in the Brocade VDX 6940-36Q be replaced in the field?
    Yes, it has 5x field-replaceable fan units (FRUs), with each FRU housing 2 fans.
  • What type of power supplies does the Brocade VDX 6940-36Q include, and how do they function?
    It includes 2x internal, redundant, field-replaceable, load-sharing AC/DC power supplies for continuous operation.
  • What is the switching capacity and forwarding rate of the Brocade VDX 6940-36Q?
    The switching capacity is 2.88 Tbps, and the forwarding rate is 2.16 billion packets per second (Bpps).
  • What are the operating and non-operating temperature ranges of the Brocade VDX 6940-36Q?
    Operating temperature ranges from 0°C to 40°C, and non-operating/storage temperature ranges from -25°C to 70°C.
  • How does humidity affect the VDX 6940-36Q, and what are the recommended humidity levels?
    Operating humidity is 10% to 85% non-condensing, and non-operating/storage humidity is 10% to 90% non-condensing, to prevent moisture-related issues.
  • What are the altitude limits for operating and storing the Brocade VDX 6940-36Q?
    The operating altitude limit is up to 3,048 meters (10,000 feet), and the non-operating/storage altitude limit is up to 12 kilometers (39,370 feet).
  • How many MAC addresses can the Brocade VDX 6940-36Q's address table hold?
    It can hold up to 112,000 MAC addresses.

Product Review

The Brocade BR-VDX6940-24Q-AC-F offers high-performance capabilities with its 24 40GbE QSFP+ ports and a switching capacity of 2.88 Tbps, ensuring efficient handling of data-intensive applications. However, the system's operating temperature range is limited to 0°C to 40°C, which may restrict its deployment in environments with extreme temperatures. Additionally, while the inclusion of redundant, load-sharing power supplies and field-replaceable fan units enhances system reliability and uptime, the non-port-side exhaust airflow design requires careful consideration of rack placement and airflow management in data center environments.
