Some database workloads like SQL Server require high memory, storage, and I/O bandwidth, but not a high core count. Many database workloads are not CPU-intensive. Azure offers certain VM sizes where you can constrain the VM vCPU count to reduce the cost of software licensing, while maintaining the same memory, storage, and I/O bandwidth.

Some database workloads like SQL Server require high memory, storage, and I/O bandwidth, but not a high core count. Many database workloads are not CPU-intensive. Azure offers certain VM sizes where you can lower the VM vCPU count to reduce the cost of software licensing, while maintaining the same memory, storage, and I/O bandwidth.

The vCPU count can be constrained to one half or one quarter of the original VM size. These new VM sizes have a suffix that specifies the number of active vCPUs to make them easier for you to identify.

The available vCPU count can be reduced to one half or one quarter of the original VM specification. These new VM sizes have a suffix that specifies the number of available vCPUs to make them easier for you to identify. There are no additional cores available that can be used by the VM.

For example, the current VM size Standard_GS5 comes with 32 vCPUs, 448 GB RAM, 64 disks (up to 256 TB), and 80,000 IOPs or 2 GB/s of I/O bandwidth. The new VM sizes Standard_GS5-16 and Standard_GS5-8 comes with 16 and 8 active vCPUs respectively, while maintaining the rest of the specs of the Standard_GS5 for memory, storage, and I/O bandwidth.

For example, the current VM size Standard_E32s_v5 comes with 32 vCPUs, 256 GiB RAM, 32 disks, and 80,000 IOPs or 2 GB/s of I/O bandwidth. The new VM sizes Standard_E32-16s_v5 and Standard_E32-8s_v5 comes with 16 and 8 active vCPUs respectively, while maintaining the rest of the specs of the Standard_E32s_v5 for memory, storage, and I/O bandwidth.

The licensing fees charged for SQL Server are constrained to the new vCPU count, and other products should be charged based on the new vCPU count. This results in a 50% to 75% increase in the ratio of the VM specs to active (billable) vCPUs. These new VM sizes allow customer workloads to use the same memory, storage, and I/O bandwidth while optimizing their software licensing cost. At this time, the compute cost, which includes OS licensing, remains the same one as the original size.

The licensing fees charged for SQL Server are based on the avaialble vCPU count. Third party products should count the available vCPU which represents the max to be used and licensed. This results in a 50% to 75% increase in the ratio of the VM specs to available (billable) vCPUs. These new VM sizes allow customer workloads to use the same memory, storage, and I/O bandwidth while optimizing their software licensing cost. At this time, the compute cost, which includes OS licensing, remains the same one as the original size.
