====== ESXi - Home Lab - VM Storage IOPS ======
The following tests were done in my [[os:esxi:home_lab#environment|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: [[http://blogs.technet.com/b/josebda/archive/2014/10/13/diskspd-powershell-and-storage-performance-measuring-iops-throughput-and-latency-for-both-local-disks-and-smb-file-shares.aspx|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 =====
