Key Features and Improvements

1. ​​Enhanced Security Posture​

  • Patches memory leak vulnerabilities in VEM packet processing (CVE-2023-20198)
  • Implements TLS 1.2 enforcement for communication between VSM and vCenter

2. ​​Performance Optimizations​

  • 40% reduction in VSM-VEM control plane latency
  • Supports jumbo frame configurations up to 9000 MTU

3. ​​VMware Ecosystem Integration​

  • Adds NSX-T 3.2 coexistence mode for multi-hypervisor environments
  • Improves port mirroring accuracy for vRealize Network Insight

4. ​​Operational Enhancements​

  • Extended VLAN range support (VLAN 1-4094)
  • Simplified license migration process for Smart Licensing

Compatibility and Requirements

Supported Platforms Minimum Software Version Hardware Requirements
VMware ESXi 6.7 Update 3 4 vCPU, 8GB RAM
vCenter Server 7.0 U2 100GB Storage
UCS C-Series 4.1(3c) 10G NIC Recommended
