Write performance varies based on IO size, drive load, and capacity utilization.Ĥ Lsv2-series VMs do not provide host cache for data disk as it does not benefit the Lsv2 workloads.ĥ Lsv2-series VMs can burst their disk performance for up to 30 minutes at a time.Ħ VMs with more than 64 vCPUs require one of these supported guest operating systems: Achieving maximum performance requires using either the latest WS2019 build or Ubuntu 18.04 or 16.04 from the Azure Marketplace. Local NVMe disk aren't encrypted by Azure Storage encryption, even if you enable encryption at host.ģ Hyper-V NVMe Direct technology provides unthrottled access to local NVMe drives mapped securely into the guest VM space. This disk is Ephemeral, and all data will be lost on stop/deallocate.Ģ Local NVMe disks are ephemeral, data will be lost on these disks if you stop/deallocate your VM.

This ensures the NVMe drives can be fully dedicated to application use. Standard_L80s_v2 provides 800 GiB at 40,000 IOPS and 800 MBPS). This disk provides 80 GiB of storage, 4,000 IOPS, and 80 MBps transfer rate for every 8 vCPUs (e.g. Max burst uncached data disk throughput (IOPs/MBps) 5ġ Lsv2-series VMs have a standard SCSI based temp resource disk for OS paging/swap file use (D: on Windows, /dev/sdb on Linux). Uncached data disk throughput (IOPs/MBps) 4 VM Generation Support: Generation 1 and 2 To learn more, see Optimize performance on the Lsv2-series virtual machines for Windows or Linux.

The high throughput and IOPs of the local disk makes the Lsv2-series VMs ideal for NoSQL stores such as Apache Cassandra and MongoDB which replicate data across multiple VMs to achieve persistence in the event of the failure of a single VM.

The Lsv2 and Ls-series do not support the creation of a local cache to increase the IOPs achievable by durable data disks. This allows for greater IOPs / throughput for your workloads. The Lsv2-series VMs are optimized to use the local disk on the node attached directly to the VM rather than using durable data disks.
