ESXi - Home Lab - VM Storage IOPS
The following tests were done in my Home Lab Environment.
VM used:
- OS: Windows Server 2012 R2
- RAM: 3GB
- CPU: 2
- Partitions
- C:\ (128GB, OS)
- E:\ (10GB, local HDD)
- F:\ (10GB, NFS on NAS)
- G:\ (10GB, local SSD)
All partitions are thick disks (eager zeroed).
DiskSpd was used to do the tests. https://github.com/Microsoft/diskspd
Tests inspired by this article: DiskSpd, PowerShell and storage performance: measuring IOPs, throughput and latency for both local disks and SMB file shares
DiskSpd Parameters
- file size: 8GB
- duration: 60s
- random
- threads: 8
non-optimal parameters, could be optimized
Summary - IOPS
