691367-B21 Use Case
High-Density Virtualization Networking for Enterprise Data Centers
In a large enterprise running VMware ESXi clusters on HP BladeSystem c7000 enclosures, the 691367-B21 HP BLc VC FlexFabric-20/40 F8 Module delivers converged LAN/SAN connectivity at 20/40 GbE per port. By collapsing eight physical I/O uplinks into four FlexFabric channels, IT administrators achieve up to 50% reduction in cabling complexity while guaranteeing lossless storage traffic and dynamic bandwidth allocation. The result: simplified network topology, accelerated VM provisioning by 30%, and predictable performance for mission-critical applications.
Multi-Tenant Cloud Infrastructure for Service Providers
A cloud service provider deploying multi-tenant workloads on HP Virtual Connect networks leverages the 691367-B21 FlexFabric-20/40 F8 Module to partition converged fabrics into isolated Flex-10 networks with per-tenant QoS policies. This ensures each tenant’s VMs and iSCSI storage streams operate on dedicated virtual NICs, eliminating noisy-neighbor issues. Providers achieve 99.99% SLA compliance, streamlined tenant onboarding in under 15 minutes, and up to 40% lower capital expenditure by maximizing existing blade chassis investment.
Low-Latency, High-Availability Database Clusters in Financial Services
A financial institution operating in-memory database clusters on HP BladeSystem infrastructure uses the 691367-B21 HP BLc VC FlexFabric-20/40 F8 Module to create dual-fabric, active/active connectivity for IBM DB2 and Oracle RAC nodes. With sub-microsecond link failover and dedicated lossless Fibre Channel over Ethernet (FCoE) tunnels, the bank achieves 6-nine availability and <2 μs port latency. This configuration guarantees continuous trading operations, accelerates transactional throughput by 25%, and ensures compliance with stringent regulatory RPO/RTO requirements.
