Storage Spaces Config for hosting VM’s

Hi all,

I was hoping to get some advice on what the minimum performance metrics would to be on MS storage space drive for Hyper-V. This drive to host multiple VM’s. ( I am aware this may be difficult to answer due to different types of VM’s and applications that run within them )
Our test is running on below server.
Dell R730XD Server – 3.5” 12 Bay
Dual Intel Xeon E5-2690 V4 – 14 Core
Dell Broadcom 5720 Quad Port 1GB NDC
256GB RAM
H730/1GB RAID Controller –
1 x Dell Samsung PM1725a PCI 1.6TB NVMe SSD Drive
3 x ST16000NM001G Seagate Exos X16 3.5" 16000 GB Serial ATA III drives in NON-RAID Model

Testing with Crystal Disk Mark.

Storage Space drive setup = 1 x NVME, 2 x 16GB Mechanical VD = Mirror – no tiering. ( we found Tiering so much slower on CDM Tests )
Attached screen shot setup of CDM.
Setting – Default.
Profile – Peak performance, Read & Write Mix
Cycle’s = 1
Test file 64GB

Also, is there a specific recommended setup on CDM for testing drives that would be hosting virtual machines. Essentially we are trying to establish base line minimum performance requirements for a Virtual drive running virtual machines.

Hi,

To be honest, it's hard to say the minimum performance requirement for Hyper VM storage. Also, it's hard for us the measure the different performances for different disk types combination and configurations.

Below are some related Hyper V storage articles for your reference:
