DCadsv5-series VMs offer a combination of vCPU and memory for most production workloads. These confidential VMs use AMD's third-Generation EPYC™ 7763v processor in a multi-threaded configuration with up to 256 MB L3 cache. These processors can achieve a boosted maximum frequency of 3.5 GHz. Both series offer Secure Encrypted Virtualization-Secure Nested Paging (SEV-SNP). SEV-SNP provides hardware-isolated VMs that protect data from other VMs, the hypervisor, and host management code. Confidential VMs offer hardware-based VM memory encryption. These series also offer OS disk pre-encryption before VM provisioning with different key management solutions. DCadsv5-series offer a combination of vCPU, memory, and temporary storage for most production workloads.

- 1Temp disk speed often differs between RR (Random Read) and RW (Random Write) operations. RR operations are typically faster than RW operations. The RW speed is usually slower than the RR speed on series where only the RR speed value is listed.
- Storage capacity is shown in units of GiB or 1,024^3 bytes. When you compare disks measured in GB (1,000^3 bytes) to disks measured in GiB (1,024^3) remember that capacity numbers given in GiB may appear smaller. For example, 1,023 GiB = 1,098.4 GB.
- Disk throughput is measured in input/output operations per second (IOPS) and MBps where MBps = 10^6 bytes/sec.

1Some sizes support bursting to temporarily increase disk performance. Burst speeds can be maintained for up to 30 minutes at a time.
Storage capacity is shown in units of GiB or 1,024^3 bytes. When you compare disks measured in GB (1,000^3 bytes) to disks measured in GiB (1,024^3) remember that capacity numbers given in GiB may appear smaller. For example, 1,023 GiB = 1,098.4 GB.
Disk throughput is measured in input/output operations per second (IOPS) and MBps where MBps = 10^6 bytes/sec.
Data disks can operate in cached or uncached modes. For cached data disk operation, the host cache mode is set to ReadOnly or ReadWrite. For uncached data disk operation, the host cache mode is set to None.

- Expected network bandwidth is the maximum aggregated bandwidth allocated per VM type across all NICs, for all destinations. For more information, see Virtual machine network bandwidth
- Upper limits aren't guaranteed. Limits offer guidance for selecting the right VM type for the intended application. Actual network performance will depend on several factors including network congestion, application loads, and network settings. For information on optimizing network throughput, see Optimize network throughput for Azure virtual machines.
- To achieve the expected network performance on Linux or Windows, you may need to select a specific version or optimize your VM. For more information, see Bandwidth/Throughput testing (NTTTCP).
