1. What is a Host Type in Azure VMware Solution?
In Azure VMware Solution (AVS), a Host Type refers to a specific configuration of compute, storage, and networking resources provided within the Azure cloud environment. These host types are bare-metal, hyper-converged servers dedicated to a customer’s AVS private cloud.
Each host type has different CPU, memory, storage, and network capabilities, allowing organizations to choose the best fit for their workload requirements.
Key Aspects of Host Types in AVS:
- Dedicated Bare-Metal Hosts – Each host is exclusive to a customer’s AVS private cloud, providing secure and isolated infrastructure.
- Cluster Deployment – A minimum of three hosts is required per cluster, with a maximum of 16 hosts per cluster. Multiple clusters can exist within a private cloud.
- Consistency in Host Type – All hosts within a single private cloud must be of the same type. If different host types are needed, a separate private cloud must be deployed.
- Networking – Most host types use 4x 25 Gb NICs, while the latest AV64 host type features a single 100 Gb NIC.
- Storage – The storage capacities are determined by vSAN configurations, affecting usable storage based on RAID policies.
Available Host Types in AVS
| Host Type | Use Case |
|---|---|
| AV36 | Standard workloads, general-purpose use. |
| AV36P | Enhanced performance with improved CPU, memory, and storage. |
| AV52 | Best for compute-intensive and storage-heavy workloads. |
| AV64 | Expansion-only host used for scaling AVS clusters. |
