766490-B21 Use Case
Enterprise Data Center Virtualization with HP FlexFabric 10Gb 2-Port 536FLB Adapter (766490-B21)
In a large-scale VMware or Microsoft Hyper-V environment, IT architects deploy the HP FlexFabric 10GB 2-Port 536FLB Adapter (766490-B21) to consolidate storage, management, and VM traffic on two high-performance 10GbE ports. Hardware offloads (NVGRE, VXLAN, iSCSI, and RDMA) free up CPU cycles, enabling up to 30% higher VM density per host. Outcome: streamlined network architecture, lower TCO, and predictable, low-latency performance for mission-critical applications.
Hybrid Cloud Connectivity and Tenant Isolation for Multi-Tenant Service Providers
Cloud service providers leverage the HP FlexFabric 10Gb 2-Port 536FLB Adapter (766490-B21) in HPE ProLiant servers to unify Ethernet and storage fabrics. Network-partitioning (NPAR) creates up to four FlexNICs per port for secure multi-tenant segmentation, while SR-IOV accelerates VM-to-cloud data transfers. Outcome: scalable and secure hybrid cloud connectivity, simplified fabric management, and guaranteed bandwidth per tenant, driving SLA compliance and higher customer satisfaction.
High-Availability Virtual Desktop Infrastructure (VDI) Deployments
In Citrix or VMware Horizon VDI farms, the HP FlexFabric 10Gb 2-Port 536FLB Adapter (766490-B21) delivers redundant 10GbE links with Dynamic Failover and RSS-based load balancing. By offloading TCP/IP and iSCSI processing, boot storms and user login surges are absorbed without CPU contention. Outcome: accelerated desktop provisioning, sub-second login times, and continuous availability—ensuring a seamless end-user experience and simplified network operations.
