Design Decisions 6 290+ in VMware Validated Design for SDDC Reduces risk by providing a baseline of standardization. Ensures the design meets the design objectives. Reinforces standardization with justification and implications. Easy to follow checklist form.
Example Design Decisions VMware Validated Design for SDDC NSX Design > Routing Design > Routing Model Design Decisions (4.1) Decision ID Design Decision Design Justification Design Implication SDDC-VI-SDN-017 Deploy NSX Edge Services Gateways in an ECMP configuration for north/south routing in both management and shared edge and compute clusters. The NSX ESG is the recommended device for managing north/south traffic. Using ECMP provides multiple paths in and out of the SDDC. This results in faster failover times than deploying Edge service gateways in HA mode. ECMP requires 2 VLANS for uplinks which adds an additional VLAN over traditional HA ESG configurations. SDDC-VI-SDN-018 Deploy a single NSX UDLR for the management cluster to provide east/west routing across all regions. Using the UDLR reduces the hop count between nodes attached to it to 1. This reduces latency and improves performance. UDLRs are limited to 1,000 logical interfaces. When that limit is reached, a new UDLR must be deployed. SDDC-VI-SDN-019 Deploy a single NSX UDLR for the shared edge and compute, and compute clusters to provide east/west routing across all regions for workloads that require mobility across regions. Using the UDLR reduces the hop count between nodes attached to it to 1. This reduces latency and improves performance. UDLRs are limited to 1,000 logical interfaces. When that limit is reached a new UDLR must be deployed.

Availability Zones VMware Validated Design for SDDC AVAILABILIITY ZONE AVAILABILIITY ZONE Characteristics • “Islands” of infrastructure for physical isolation or building-level redundancy and high-availability. • Positioned within “metro” distance to allow synchronous storage replication. (~50km/30mi with low single-digit latency and large bandwidth) • Allows the SDDC equipment across the availability zone to operate in an active/active manner as a single virtual data center or region. • Isolated enough from each other to stop the propagation of failure or outage across their boundaries. Early Access Preview • Guidance for vSAN Stretched Clusters within a region.
One Pod – Consolidated Management and Workload VMware Validated Design for SDDC New in Version 4.1 § Consolidates Management, Edge, and Workload into a single pod. § Requires only a minimum of 4 ESXi hosts § All functional testing and validation of the design is done using vSAN. § Any supported storage may be used. Adjust the operations guidance. § Network Transport § Supports both L2 and L3 transport services. § Scalable and vendor-neutral network, use an L3 transport. § Ready for Scale § Expandable to a 32 ESXi host pod. § SDDC solutions easily scale – deployed w/ native or NSX load balancing in place. § Transitions to Two-Pod Distributed Management and Workload (Standard) § Downtime Required § Single Region and Single Availability Zone § License Flexibility for NSX (No Universal Objects) External Connection WAN/LAN

Network Transport Services § The VMware Validated Designs supports both L2 and L3 transport services. § For a scalable and vendor-neutral data center network, use an L3 transport. § When deciding to use L2 or L3, consider the following: § The NSX ECMP Edge devices establish L3 routing adjacency with the first upstream L3 device to provide equal cost routing for management and workload virtual machine traffic. § The investment you have today in your current physical network infrastructure. § All design documentation is provided for an L3 transport. You must appropriately adjust the design deployment and day-two operations guidance under the context of an L2 transport. Minimal Design Requirements § One 10 GbE port on each ToR for host uplinks. § Host uplinks are not configured in an ether-channel (LAG/vPC) § Layer 3 device that supports BGP § IGMP support required by vSAN and NSX Hybrid Mode 20 VMware Validated Design for SDDC
Example: L3 Leaf-and-Spine Topology Subnet Guidelines § Use /24 subnets to reduce confusion and mistakes when working with IPv4 subnets. § Use .1 as the (floating) interface with .2 and .3 for Virtual Router Redundancy Protocol (VRPP) or Hot Standby Routing Protocol (HSRP). § Use the RFC1918 IPv4 address space for these subnets and allocate one octet by region and another octet by function. For example, the mapping 172.regionid.function.0/24 results in the following sample subnets 23 VMware Validated Design for SDDC Pod Function Sample VLAN Sample IP range Management Management 1611 (Native) 172.16.11.0/24 Management vMotion 1612 172.16.12.0/24 Management VXLAN 1614 172.16.14.0/24 Management VSAN 1613 172.16.13.0/24 Shared Edge and Compute Management 1631 (Native) 172.16.31.0/24 Shared Edge and Compute vMotion 1632 172.16.32.0/24 Shared Edge and Compute VXLAN 1634 172.16.34.0/24 Shared Edge and Compute VSAN 1633 172.16.33.0/24 Note: The above ranges are meant as samples.

vSAN Optional for Management Pod Primary Storage § Previous releases required vSAN as primary storage in the management pod. This requirement has been relaxed in the 4.1 release. § All functional testing and validation of the design is done using vSAN. § Although the VMware Validated Designs highly recommend the use of vSAN, in particular for the management pods, any supported storage solution may be used. § If a storage solution other than vSAN is selected: § You must appropriately adjust the design deployment and day-two operations guidance under the context of vSAN. § The storage design must match or exceed the capacity and performance capabilities of the vSAN configuration in the design.

Two-Layer Certificate Authority + Certificate Replacement CertGenVVD tool saves you time when creating signed certificates. See VMware Knowledge Base article 2146215. Certificate Mode § VMCA Hybrid Mode § All user-facing certificates are signed by a certificate authority (CA). § All virtual infrastructure management components use TLS/SSL certificates that are signed by the VMware Certificate Authority (VMCA). § Supports a Two-Layer CA environment. Certificate Replacement § If the CA-signed certificates expire after you deploy the SDDC, you must replace them individually on each affected component. § Provides guidance for replacing all CA-signed certificates that are expiring. * VMware Validated Design for SDDC
