Set Up The Second Hard Drive (Initialize & Partition Disk) Tools List: Partition manager software - EaseUS Partition Master. All you need is to press the power button to restart your computer and enter the next guide to set up the second hard drive. BTW even on an external SSD a VM should perform quite nicely - best if you use a SATA->USB3 connector but even with a USB2 connector it will work fine.Ī good use for any older 110 / 120 GB SSD's you might have over from earlier models -good use for these BTW. Now, you've installed the second hard drive into your computer.
On an SSD you can usually get away with it though. If you keep VM and HOST OS'es on the same HDD you will get quite a considerable performance degradation -especially at VM power on (boot) - you'll probably see the HDD light on continuously for several minutes as the VM powers on. In this case, the wizards drop-down list contains a list of installation media that were previously used with Oracle VM VirtualBox. If you have to use Spinners - then get one with the fastest RPM (7200 at least) and THE LARGEST CACHE SIZE POSSIBLE - I suspect that as there are a load of cheap high capacity 5400 RPM HDD's on the market but with tiny cache amounts - these really KILL performance - even if you have an I7 processor.Ī decent graphics card helps as well - also the Host shouldn't be under too much load if you want concurrent decent performance from the VM.Īgain often it's the efficiency of the HDD that is the biggest blockage into vm performance - followed by RAM - these days not having enough RAM is rarely an issue -even cheap laptops have 8 GB - more than enough to run a Windows host and any sort of VM - other Windows or a Linux VM etc. Oracle VM VirtualBox will then present this file as a CD or DVD-ROM drive to the virtual machine, much like it does with virtual hard disk images. The BIGGEST factors on VM performance are of course availability of RAM and HDD / SSD speed.Īssuming you have sufficient RAM in your computer the best way to gain best performance for your VM is to run it off an SSD. When you add a hard disk to a virtual machine, you can create a virtual disk, add an existing virtual disk, or add a mapped SAN LUN.
You can add another hard disk if you run out of disk space, if you want to add a boot disk, or for other file management purposes.
VM's actually do NOT have a huge CPU overhead - unless of course there is a lot of intensive CPU type work being done on the VM - normal workloads don't incur a huge overhead. To install ClearPass, we need to add another disk partition to this deployed VM. When you create a virtual machine, a default virtual hard disk is added.
You would get a marginal performance improvement but vms have quite a high cpu overhead so do not expect a huge performance increase.Hi there
