Lasv5 size series

The Lasv5-series of Azure Virtual Machines (VMs) features high-throughput, low latency, directly mapped local NVMe storage. These VMs utilize AMD's fifth Generation EPYC™ 9005 processors that can achieve a boosted maximum frequency of 4.5 GHz. The Lasv5-series VMs are available in sizes from 2 to 160 vCPUs, with 8 GiB of memory allocated per vCPU and 240 GB of local NVMe temp disk capacity allocated per vCPU, with up to 30.7 TB (8x3.84 TB) of local temp disk capacity available on the largest size.

Lasv5-series VMs are well suited for scale-up or scale-out storage workloads that need a balance of SSD capacity, compute, and memory. These VMs are perfect for big data, relational, NoSQL databases, data analytics, and data warehousing workloads. Examples include Cassandra, MongoDB, Cloudera, Spark, Elastic Search, Redis, and other data-intensive applications.

Lasv5-series VMs support Standard SSD, Standard HDD, and Premium SSD remote disk types. You can also attach Ultra Disk storage based on its regional availability. Remote Disk storage is billed separately from virtual machines. For more information, see pricing for disks.

• NVMe Overview
• FAQ for temp NVMe disks

Table definitions

• Temp disk performance depends on many factors, including block size, workload patterns of read and write operations, queue depth (QD), and others. View temp disk performance specifications as best-case performance numbers, assuming 4 KB block sizes and QD=256 for IOPS, and 256 KB block sizes with QD=64 for throughput. Write performance is heavily impacted by how many blocks are in use on a device. Temp disk write performance specifications assume a device has a clean slate to enable the best performance. During steady-state operations, write performance is lower than the published specifications.
• For Lasv5 and Lasv4, temp disk refers to the NVMe local data disks used by the VM. While Lsv3 and Lasv3 have NVMe local data disks and a SCSI local temp disk, Lasv5 and Lasv4 only have NVMe local temp disks. There's no SCSI local temp disk on Lasv5.
• Disk throughput is measured in input/output operations per second (IOPS) and MBps, where MBps = 10^6 bytes/sec.
• To learn how to get the best local storage performance for your VMs, see the NVMe Temp Disk FAQ.

Table definitions

• Some 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 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 might 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.

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 depends 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 might need to select a specific version or optimize your VM. For more information, see Bandwidth/Throughput testing (NTTTCP).
