Azure VMware Solution clusters are based on a hyperconverged infrastructure. The following table shows the CPU, memory, disk, and network specifications of the host.
| Host type | CPU (cores/GHz) | RAM (GB) | vSAN Architecture | vSAN cache tier (TB, raw***) | vSAN capacity tier (TB, raw***) | Regional availability |
|---|---|---|---|---|---|---|
| AV36 | Dual Intel Xeon Gold 6140 CPUs (Skylake microarchitecture) with 18 cores/CPU @ 2.3 GHz, Total 36 physical cores (72 logical cores with hyperthreading) | 576 | OSA | 3.2 (NVMe) | 15.20 (SSD) | Selected regions (*) |
| AV36P | Dual Intel Xeon Gold 6240 CPUs (Cascade Lake microarchitecture) with 18 cores/CPU @ 2.6 GHz / 3.9 GHz Turbo, Total 36 physical cores (72 logical cores with hyperthreading) | 768 | OSA | 1.5 (Intel Cache) | 19.20 (NVMe) | Selected regions (*) |
| AV48 | Dual Intel Xeon Gold 6442Y CPUs (Sapphire Rapids microarchitecture) with 24 cores/CPU @ 2.6 GHz / 4.0 GHz Turbo, Total 48 physical cores (96 logical cores with hyperthreading) | 1,024 | ESA | N/A | 25.6 (NVMe) | Selected regions (*) |
| AV52 | Dual Intel Xeon Platinum 8270 CPUs (Cascade Lake microarchitecture) with 26 cores/CPU @ 2.7 GHz / 4.0 GHz Turbo, Total 52 physical cores (104 logical cores with hyperthreading) | 1,536 | OSA | 1.5 (Intel Cache) | 38.40 (NVMe) | Selected regions (*) |
| AV64 | Dual Intel Xeon Platinum 8370C CPUs (Ice Lake microarchitecture) with 32 cores/CPU @ 2.8 GHz / 3.5 GHz Turbo, Total 64 physical cores (128 logical cores with hyperthreading) | 1,024 | OSA / ESA**** | 3.84 (NVMe) / N/A**** | 15.36 (NVMe) / 19.25 (NVMe)**** | Selected regions (**) |
An Azure VMware Solution cluster requires a minimum number of three hosts. You can use hosts of the same type only in a single Azure VMware Solution private cloud. Hosts used to build or scale clusters come from an isolated pool of hosts. Those hosts passed hardware tests and had all data securely deleted before being added to a cluster.
All of the preceding host types have 100-Gbps network interface throughput.
*Details are available via the Azure pricing calculator.
**AV64 prerequisite: An Azure VMware Solution private cloud deployed with AV36, AV36P, or AV52 is required before adding AV64.
***Raw is based on International Standard of Units (SI) reported by disk manufacturers. Example: 1 TB Raw = 1000000000000 bytes. Space calculated by a computer in binary (1 TB binary = 1099511627776 bytes binary) equals 931.3 gigabytes converted from the raw decimal.
****ESA applies to AV64 Gen 2 deployments.
