Dv4 sizes series

vCPUs (Qty.) and Memory for each size

VM Basics resources

• What are vCPUs
• Check vCPU quotas

Local (temp) storage info for each size

Remote (uncached) storage info for each size

Storage resources

• Introduction to Azure managed disks
• Azure managed disk types
• Share an Azure managed disk

Table definitions

• ¹Some sizes support bursting to temporarily increase disk performance. Burst speeds can be maintained for up to 30 minutes at a time.
• ²Special Storage refers to either Ultra Disk or Premium SSD v2 storage.
• Storage capacity is shown in units of GiB or 1024^3 bytes. When you compare disks measured in GB (1000^3 bytes) to disks measured in GiB (1024^3) remember that capacity numbers given in GiB may appear smaller. For example, 1023 GiB = 1098.4 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.
• To learn how to get the best storage performance for your VMs, see Virtual machine and disk performance.

Network interface info for each size

Networking resources

• Virtual networks and virtual machines in Azure
• Virtual machine network bandwidth

Table definitions

• 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).
