i want to use my desktop for learning same IT stuff. Now my pc have one 128GB SD disk and 500GB sata disk ,after i change to SD disk my system is running very fast, I would like to seek for advice all my virtual machine create in VMware workstation suppose locate at SD disk or SATA Disk to avoid slow performance issue.

If you want to go even more faster, buy another SSD SATA Hard drive and put all your VMs files inside it.....

If you don't want to buy another SSD, my advice is to put some VMs in your SSD and some others in the SATA drive (balance your Hard Drive workload according to your needs).

Remember also to have at least 32GB of RAM.....(It could be mandatory to learn Microsoft stuff).

The performance of your VMs is not just dependent on your Hard disk. It also depends on RAM and CPU of the host system(Your desktop). So make sure you are covered in terms of all the required resources.

If you can give us more details on number of machines and machine configurations you will be running we can suggest a config for your host machine.

With this post, I'd like to report to you my "IT STUFF" Lab environment :-)

Here is my VMware lab in a Windows 7 machine with VMware Workstation 10 on it:

•      Intel Core i7 2860QM “Sandy Bridge” CPU (Quad-core, 2.5 GHz, 8MB L3 cache)
•      64 GB DDR4 RAM
•      2x 512 GB SSD SATA
•      Windows 7 x64 with VMware workstation
•      Dual graphics: Intel HD 3000 + nVidia Quadro 2000M

With this specs you can test basically what you want in your Lab.

Actually, this is my configuration:

•      vSphere 5.5 environment composed of 3 ESXi hosts (2 in a cluster and 1 stand-alone) with 1 vCenter Server (on another Windows Server VM)
•      A Hyper-V environment composed of 2 clustered hosts (with a CSV) and 1 stand-alone host.
•      A Windows 2012 fileshare server
•      2 Virtual Storage: an Openfiler installation and a Data Ontap NetApp Simulator.
•      A “virtual VTL” (mhVTL) to test tape backups.
•      A Windows 2012 Server VM for Veeam Backup & Replication.
•      A Windows Server VM for Veeam ONE.
•      A Windows Server VM running System Center Operations Manager (SCOM) and Veeam Management Pack

Here is a detailed guide:


Then, if you want to configure Openfiler as an “iSCSI SAN” for your lab, you may follow this guide:


Obviously this is a very powerful lab, but you may scale (with less cost) in terms of CPU, amount of RAM e SSD SATA disk size.....it's your choice....

I think your desktop PC is adequate, and you do not have to go over the top!

Memory in your host will always be the bottleneck!

or, if you want a better lab, see here...and use AutoLab!

Openfiler is old, outdated and slow by comparison with FreeNAS also included with AutoLab!


Create VMs like ESXi host, vCenter and Storage VM (Open filer or FreeNAS) on SATA drive. On storage VM create the VMDK file on SSD drive to store VMs data running inside the ESXi hosts and configure iSCSI connection for ESXI host and attach LUN create in storage VM. So that all VM running inside the ESXi host use IOs from SSD drive and VMs running on VMware Workstation use IOs from SATA drive.
