In the case of a PowerEdge R730XD loaded with 24 drives, you still need an OS that can “present” that storage to your network. You’ll need some kind of OS in that can support things like NFS, SMB, or iSCSI. And if you boot VMWare ESXi your storage will be specific to the host only unless you get VSAN licenses to share the host’s storage with other hosts in the VSPhere. So a JBOD may sound great, but the outcome of such an implementation could be disappointing if you need more than a large pool of network attached storage.

“Enterprise” class drives are designed and engineered for continuous operation. “Consumer” class drives are designed to have periods where the PC will be powered off and the drives will be at cold rest. Enterprise class drives are also designed with more data pathways to allow for higher IOPS, which is in essence how many simultaneous operations the drive can sustain before the cache fills and slows the performance.

Thank you for your comment below, Robert! We wholeheartedly agree!

This is wonderful! Paying it forward it a great way to make the world go around!

To your comment below, Lee, we were thinking the same thing, hence our question about solar or wind power. I guess you can’t have an off-the-charts homelab without the juice to run it!

I do not want to see the electric bill on #1.

Great post! As you start learning about virtualization a few terms that may come in handy: Host – the physical server and the OS that physical server will boot from (Windows Server, VMWare ESX, or Hyper-V server are the bigger names out there)
Guest – the virtualized instance of an OS, can be Windows, UNIX, LINUX, or any operating system running in your virtual machine server.
Virtualization engine or virtual machine server – The thing your physical server loads or the OS your physical server loads to allow the creation of shared resource pools that you can share out to your virtual machines. Also called a virtual machine server. Can be an OS as in the case of VMWare ESX or Microsoft Hyper-V server, or it can be an application server running on your physical host OS as in the case of a Windows 2016 Server running Hyper-V services.
Virtual server – a server-based OS running within your virtual machine server :-)
Virtual machine – any configured bootable operating system used by your virtual machine server to boot an OS kernel. Windows 10, Ubuntu, pretty much anything you can boot a computer with, you can virtualize.

You can also uses virtualization tools like VMWare ESX to boot on Apple hardware and then you can create virtual machines with Apple OS X versions. Only works on the Intel based Macs, not the Apple A5 CPU.

Now I’ll wait for Mike to start a blog post on data virtualization because that’s where the fun gets going, LOL.
