Frequently Asked Questions (FAQs)
What is the primary function of the HPE 720190-B21 QSFP+ module in a BladeSystem c-Class environment? +
The HPE 720190-B21 is designed to provide high-speed 40GbE connectivity within the BladeSystem c-Class architecture. It enables high-bandwidth data transmission between server blades and network infrastructure, facilitating the low-latency communication required for modern data center workloads, virtualization, and high-performance computing clusters.
Is the 720190-B21 module compatible with other HPE BladeSystem interconnect switches? +
This module is engineered specifically for compatibility with select HPE c-Class interconnect modules. It ensures seamless integration and hardware recognition within the BladeSystem ecosystem. For specific switch model compatibility, verify your current interconnect module’s technical specifications or matrix to ensure the QSFP+ port supports the 40GbE standard provided by this specific transceiver.
What cabling infrastructure is required to support the HPE 720190-B21? +
The 720190-B21 utilizes the QSFP+ form factor, which typically requires MPO/MTP multi-mode fiber cabling for optimal performance. It is important to ensure your fiber plant meets the necessary OM3 or OM4 specifications to maintain signal integrity over the distance required for your specific data center layout and link budget requirements.
How does the 720190-B21 manage power efficiency in a dense BladeSystem configuration? +
HPE designs these QSFP+ modules for high power efficiency, which is critical when populating dense BladeSystem enclosures. By optimizing power consumption per port, this module helps maintain the thermal and electrical profiles of the enclosure, reducing the overall overhead on your power supplies and cooling systems during peak traffic loads.
What is the maximum data throughput provided by the HPE 720190-B21? +
This module delivers a maximum throughput of 40 Gigabits per second (Gbps). This capacity is essential for eliminating bottlenecks in top-of-rack or chassis-level switching environments where large amounts of east-west traffic or storage replication are occurring between blades within the c-Class infrastructure.
How do I ensure the 720190-B21 is recognized correctly by the HPE BladeSystem software? +
The module is designed to communicate via standard I2C management interfaces, which allow the switch firmware to identify the manufacturer, serial number, and performance metrics. Simply inserting the module into a compatible QSFP+ port initiates the handshake process, allowing the system to verify the part and bring the link online without complex manual configuration.
Can the 720190-B21 be used for high-availability cluster deployments? +
Yes, this transceiver is well-suited for high-availability (HA) cluster deployments. Its reliable performance and low-latency characteristics make it ideal for redundant interconnect configurations. Using these modules in a redundant topology ensures that your blade servers maintain constant, high-speed access to the network core even if a single link or switch module fails.
What physical environment is recommended for deploying the 720190-B21? +
The module is designed for standard data center environments that follow established ASHRAE thermal guidelines. To ensure optimal operational longevity and performance, the blade chassis should be properly ventilated, and the QSFP+ ports should be kept free of dust or obstructions to maintain clean optical connectivity and consistent link status.
How can I obtain a bulk quote for the 720190-B21 from BuyRouterSwitch.com? +
