An architect is designing the physical and host networking architecture for vSAN Express Storage Architecture (ESA) in a VMware Cloud Foundation (VCF) deployment.
The customer requires maximum storage performance for latency-sensitive, high-IOPS workloads in analytics, artificial intelligence (AI), and machine learning (ML). To achieve this, the design must incorporate Remote Direct Memory Access (RDMA) over Converged Ethernet (RoCE v2) for vSAN data traffic while maintaining a converged network for all other VCF traffic types.
During requirements gathering, the customer specified the following technical requirements:
Ultra-low latency and maximum throughput for vSAN data traffic.
Support for Priority Flow Control (PFC) to ensure lossless Ethernet for RoCE v2 traffic.
Deterministic performance with no dynamic load balancing that could introduce variability in storage I/O paths.
End-to-end jumbo frame support across the fabric.
High availability with tolerance to single NIC or switch failures.
Converged design where RoCE v2 vSAN traffic is separated by the physical infrastructure with management, vMotion, and NSX overlay traffic traversing a secondary network.
Given these RDMA-enabled vSAN networking requirements in a multi-rack VMware Cloud Foundation (VCF) environment, what are the three key design decisions? (Choose three.)
