The effect of SSD on Virtual Machine performance

The effect of SSD on Virtual Machine performance

Article
The effect of SSD on Virtual Machine performance. Well, today, we have something unusual compared to our previous SysAdmin classes. it is because we now use SSD in our hypervisor. During the training, the hypervisor is used to host virtual machines according to the scenarios. sometimes we need to install more than 10VMs at the same time which takes ages in the previous storage. In this test, we install solaris OS on proxmox hypervisor. For your information, Installing Solaris 10 on proxmox hypervisor, is a little bit tricky as you need to carefully select hardware for the Operating System. Wrong selection of hardware, can lead to incompatibility and result to kernel panic :-(. Therefore, some of the hardware doesnt support hardware-assisted virtualisation (intel-vt / AMD-V) which result to slower performance.…
