Supported virtual machine types

Supported VM sizes for backends

On Azure, WEKA is deployed in a multi-container architecture using the storage-optimized Lsv3-series and Lasv3-series Azure Virtual Machines (Azure VMs). These VMs feature high throughput, low latency, and directly mapped local NVMe storage.

Each VM size has a specific number of NICs, but only one is used for all traffic in UDP mode through the management interface.

The following table lists the VM sizes applied by the Terraform package on the backends:

VM size	vCPU	Memory (GiB)	NVMe disks	Max NICs	BW (Mbps)
Standard_L8s_v3	8	64	1x1.92 TB	4	12500
Standard_L16s_v3	16	128	2x1.92 TB	8	12500
Standard_L32s_v3	32	256	4x1.92 TB	8	16000
Standard_L48s_v3	48	384	6x1.92 TB	8	24000
Standard_L64s_v3	64	512	8x1.92 TB	8	30000
Standard_L80s_v3	80	640	10x1.92 TB	8	32000
Standard_L8as_v3	8	64	1x1.92 TB	4	12500
Standard_L16as_v3	16	128	2x1.92 TB	8	12500
Standard_L32as_v3	32	256	4x1.92 TB	8	16000
Standard_L48as_v3	48	384	6x1.92 TB	8	24000
Standard_L64as_v3	64	512	8x1.92 TB	8	32000
Standard_L80as_v3	80	640	10x1.92 TB	8	32000

Using the Azure Console, the client instances can have different virtual machine types provisioned separately from the WEKA cluster.

Mapped cores to processes

In each virtual machine size, the cores are mapped to a specific number of the compute, drive, and frontend processes. For example, in the Standard_L16s_v3 size, the cores are mapped to the following processes:

• Compute: 4

• Drive: 2

• Frontend: 1

Mapped WEKA processes for a standard_L16s_v3

VM size	# of compute cores	# of drive cores	# of frontend cores
Standard_L8s_v3	1	1	1
Standard_L16s_v3	4	2	1
Standard_L32s_v3	4	2	1
Standard_L48s_v3	3	3	1
Standard_L64s_v3	4	2	1
Standard_L80s_v3	4	2	1
Standard_L8as_v3	1	1	1
Standard_L16as_v3	4	2	1
Standard_L32as_v3	4	2	1
Standard_L48as_v3	3	3	1
Standard_L64as_v3	4	2	1
Standard_L80as_v3	4	2	1
