Bsv2-series

  • Article

Bsv2-series virtual machines run on Intel® Xeon® Platinum 8473C (Sapphire Rapids), or Intel® Xeon® Platinum 8370C (Ice Lake) processor in a hyper threaded configuration, providing low-cost CPU burstable general purpose virtual machines. Bsv2-series virtual machines utilize a CPU credit model to track how much CPU is consumed - the virtual machine accumulates CPU credits when a workload is operating below the base CPU performance threshold and, uses credits when running above the base CPU performance threshold until all of its credits are consumed. Upon consuming all the CPU credits, a Bsv2-series virtual machine is throttled back to its base CPU performance until it accumulates the credits to CPU burst again.

Bsv2-series virtual machines offer a balance of compute, memory, and network resources and are a cost-effective way to run a broad spectrum of general-purpose workloads, including large-scale micro-services, small and medium databases, virtual desktops, and business-critical applications; and are also an affordable option to run your code repositories and dev/test environments. Bsv2-Series offers virtual machines of up to 32 vCPU and 128 Gib of RAM, with max network bandwidth of up to 6250 Mbps and max uncached disk throughput of 600 Mbps. Bsv2-series virtual machines also support attachments of Standard SSD, Standard HDD, and Premium SSD disk types with a default Remote-SSD support, you can also attach Ultra Disk storage based on its regional availability. Disk storage is billed separately from virtual machines. See pricing for disks.

Size table definitions

  • 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.

  • 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).
