ESX Appliance?
-
It was an infoworld article but I can't for the life of me find it.
The basic gist was that ESXi can host more VMs per physical server then Hyper-V so you would need fewer Datacenter licenses and physical machines then you would if the datacenter were run on Hyper-V.
This is one of them but it is two years old now. I'm surprised that no one has done a more up-to-date version.

That makes sense. Considering you'd have to buy more physical servers, and a datacenter license is several thousand for EACH license, yeah...I guess I can see that.

That has always irked me about Hyper-V. It's not a true hypervisor. It's basically a hypervisor-esque application running inside Windows.

No, it is a true hypervisor, it runs underneath the Windows Server. It is basically the same as how Xen does it with Dom0.

Never touched Xen in my life, so I can't say one way or another with that.

You still install it to the device though, right? You don't/can't run Hyper-V from a flash drive or SD card like ESXi, right?

@thanksaj the new core is a hypevisor... it's just running a windows core rather than a linux core.

Sure you can. I was told by a Microsoft rep that they recommend running Hyper-V Server off of a very fast SD card.

@coliver I think I found my friday project.

Running it off of a SD card? I've heard that you need a high-end card to make it usable... I've tried running it off a regular USB stick but it was abysmally slow.
So you need a Class 10 SDHC card I assume, right?

Interesting...that is news to me. Sounds like MS is playing catch-up to get to VMware's level in a lot of ways...just my 2ยข.

You CAN have an ESXi appliance. It would just be an appliance built off of ESXi. Just like Scale is an appliance built off of KVM. Same different.
-
@thanksaj Yep I don't recall being told any specifics but yes a Class 10 card would probably be right.

Ok, so the idea is possible in theory, but tell me @scottalanmiller , have you ever heard someone refer to an ESX appliance they just bought? Or talk about getting a quote for an ESX appliance? It's just not a term you hear, at least in my experience.

He also mentioned how VMware is basically just Hyper-V, which when I calmly asked if he knew that they weren't the same thing, he just about flipped out...considering ESX had been around for years before Hyper-V hit the market (I looked it up just to confirm in my own head), I can pretty much say no. Besides, VMware is far more robust and powerful, as well as expensive than Hyper-V, and works very differently.
They are both Type 1 (bare metal) hypervisors. They are "basically" the same thing. One is older, sure. One is more robust, sure. But basically, they are the same thing. Like Chevy and Ford, they are basically the same. But people who like one or the other will generally argue with you.
VMware is not more expensive. For most use cases, it is actually cheaper.

It's features like vMotion that ESXi has that I know of no equivalent in Hyper-V. I'm by no means an expert in all the possible functions and features of ESXi, but I've seen Hyper-V a little and did not care for the interface, personally. Not compared to ESXi.
Everyone has a vMotion equivalent. That's actually a free feature of both HyperV and XenServer.

I can understand why some people think a virtual machine host is an appliance. It does a single specific task, host virtual machines. That doesn't make them right... just that I understand it.
That would be like calling anything an appliance. A server is an appliance because it does one thing... sit there and be the hardware. The OS does one thing, it hosts applications. The application is an appliance because it only does one task.

Isn't Xen free?
Both Xen (just the hypervisor like ESXi) and XenServer (the ecosystem like vSphere) are completely free, there is nothing to buy whatsoever. vMotion, fault tolerance, storage vMotion, all of that stuff is free, included and limitless.

Within the last week, yes. There was a discussion about it being so common that many VMware partners sell nothing but that.
