The VCF 9.0.1 Design Guide provides sizing best practices for vSAN stretched clusters, emphasizing capacity planning to accommodate failover conditions. It states:

“When sizing a stretched vSAN cluster, consider that in case of a site failure, all resources from the failed site must be supported by the surviving site. Therefore, compute and storage should not exceed 50% utilization per site.”

This translates into a maximum target utilization of ~45% compute and ~40% storage per site, ensuring compliance with the company’s overall 90% capacity policy when combined across both sites.

A homogeneous cluster configuration (A) ensures consistent performance and predictable recovery during failover.

Dedicated NSX instances per workload domain provide the highest level of logical isolation and allow independent upgrade cycles, fulfilling the requirement of tenant-specific customization. Each workload domain with its own NSX instance can be managed separately, updated independently, and configured with its own security policies, BGP/VRF, segments, and gateways.

NSX Federation could achieve some level of centralization but does not support independent upgrade cycles per domain. A shared NSX instance breaks isolation and would tightly couple upgrade cycles, violating two of the key stated requirements.

According to the VMware Cloud Foundation 9.0.2 Design Guide (NSX Bridging and Layer 2 Connectivity), when workloads or appliances require Layer 2 adjacency with physical network devices and do not support overlay encapsulation (Geneve), NSX Edge bridging is the validated solution.

The documentation states:

“The bridge functionality extends an overlay segment into a VLAN identified by a VLAN ID on an uplink of the NSX Edge. This enables Layer 2 connectivity between virtual machines on NSX overlay segments and physical workloads on VLAN-backed networks.”

By connecting the third-party appliance to a VLAN-backed segment and configuring NSX bridging, the appliance gains direct L2 connectivity to the firewall, while the workloads on overlay segments can still communicate seamlessly through the bridge.

This approach maintains the logical separation of NSX networks while satisfying L2 adjacency requirements, a common design pattern for integrating non-overlay-capable systems.

Advanced Memory Tiering with NVMe optimizes memory performance, essential for workloads that are latency-sensitive.

NSX Enhanced Data Path (EDP) is specifically designed for high-performance, low-latency packet processing, critical in real-time applications.Options like Global Deduplication or Deep Snapshots can negatively impact latency due to additional processing overhead.
