vSphere 8 Scalability
VMware vSphere 8 supports new configurations Maximus, which can be found here.
See a comparison with configuration maximus based on vShere 7U3 and vSphere 8.
Maximize Performance For Latency Sensitive Workloads
vShere 8 introduced Virtual Hardware level 20 which unlocks some great new features.
Let’s start with High Latency Sensitivity with Hyper-threading which is designed to support high latency sensitive workloads and deliver improved performance.
A virtual machine’s vCPU are scheduled on the same hyper-threaded physical CPU core.
This feature can be enabled on the advanced virtual machine setting and requires VM hardware level 20, which is introduced by VMware vSphere 8.
vSphere 8 Security improvements
Prevent execution of untrusted binaries: ESXi 8.0 will turn on the execInstalledOnly option by default. This prevents the execution of binaries that are not installed via a VIB.
TLS 1.2 only: vSphere 8 will not support TLS 1.0 and TLS 1.1. Both have previously been disabled by default in vSphere 7 and are now removed in vSphere 8.
SSH Automatic Timeout: SSH access is deactivated by default and in vSphere 8 a default timeout is introduced to prevent SSH sessions lingering.
Sandboxed Daemons: ESXi 8.0 daemons and processes run in their own sandboxed domain where only the minimum required permissions are available to the process.
Discontinuation of Trusted Platform Module (TPM) 1.2: ESXi 8.0 displays a warning during installation or upgrade if a TPM 1.2 device is present. The install or upgrade is not prevented.
