The Memory-and-storage optimized Mbdsv3 series is based on the fourth generation Intel® Xeon® Scalable processors and delivers higher remote disk storage performance. These new VM sizes offer up to 650,000 IOPS and 10 GB/s of remote disk storage throughput (Premium SSD v2 and Ultra Disk), up to 4 TiB of RAM and up to 650,000 IOPS and 10 GB/s throughput to remote disk storage (with NVMe interface by using Ultra Disk and Premium SSD v2).
The increased remote storage performance of these VMs is ideal for storage throughput-intensive workloads such as relational databases and data analytics applications.
The resource allocation and high-performance capabilities of the Mbdsv3 VM series make them particularly well suited for SQL Server workloads with high memory needs. Workloads such as critical online transaction processing (OLTP), data analytics, in-memory databases, data warehousing, and the consolidation of SQL Server workloads for efficient management of multiple SQL Server instances.
1 Temp 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.
2 Read IOPS are optimized for sequential reads.
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.
1Some sizes support bursting to temporarily increase disk performance. Burst speeds can be maintained for up to 30 minutes at a time.

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).
