I don’t have the luxury of having separate “production” and “staging” servers, to experiment without affecting my actual system and data.

ESXi, running on VT-d-enabled hardware, has support for DirectPath I/O passthrough – but it is far from simple and/or straight forward to use it directly with physical drives… Thus, it makes sense to give unRAID complete and absolute control of the NAS hard-drives it will manage.

The main function of unRAID is to manage storage.

unRAID runs from a USB flash drive as its boot media, and persistent memory for configuration and plugins, but ESXi doesn’t offer a “boot a VM from USB flash drive” option, nor does it support simulating a USB flash drive as a VM booting media.

So, what are the challenges in running unRAID as a VM? And what are some of the requirements I have from this set up and migration process?

The VMXNET3 and the virtio_net would probably be equal in performance when used on their respective platforms, however since the VMXNET3 driver is not native to the virtualization platform Unraid uses, it might perform worse than virtio_net and I know that Proxmox advises to only use it during VM migration, so I would suggest using the virtio_net driver for max performance and minimum overhead on Unraid.Install unRAID NAS OS as a VM on ESXi host to improve resource utilization of your home server! Some quick googling suggests that it might show up as 1, 10 or 100G in Windows but as mentioned, the link speed doesn't mean anything. In a Linux VM, the virtio_net NIC shows up as "Speed: Unknown".

The E1000, VMXNET3 and virtio_net drivers are not actually limited to the link speed shown on the NIC, so clear your mind of virtual network adapter link speeds.Įven the E1000 driver will actually transfer at multi-gigabit speeds when it shows a 1G link but with the emulation overhead, it won't perform as well as VMXNET3 and virtio_net does.

I would love to tell you myself but I can't get any Windows installation to find any drives when attempting to install it to a VM on my Unraid box and I don't have the time to work around it at the moment. Because operating system vendors do not provide built-in drivers for this card, you must install VMware Tools to have a driver for the VMXNET network adapter available. VMXNET is optimized for performance in a virtual machine. VMware definition: The VMXNET virtual network adapter has no physical counterpart. There is no native VMXNET device driver in some operating systems such as Windows 2008 R2 and RedHat/CentOS 5 so VMware Tools is required to obtain the driver. That means there is no additional processing required to emulate a hardware device and network performance is much better. On the other hand, we’ve got VMXNET3 virtual NIC, which is a completely virtualized 10 GB NIC with drivers and network processing are integrated with the ESXi hypervisor.

Typically Linux versions 2.4.19 and later, Windows XP Professional 圆4 Edition and later, and Windows Server 2003 (32-bit) and later include the E1000 driver. A driver for this NIC is not included with all guest operating systems. VMware definition: An emulated version of the Intel 82545EM Gigabit Ethernet NIC. That can lead to performance issues as the host’s CPU is required to take care of the processing normally done on a separate ASIC (Application-Specific Integrated Circuit).

The problem is that the virtual device is just as described, a piece of software acting as if it was hardware. Because of that, there is no special driver required to make it operate in a virtual environment. Speaking of E1000, it is a software emulation of a 1 GB network card, commonly available on Intel-based devices and most operating systems include built-in support.

I've spent a good while looking for answers on this and found nothing so far. Sorry for the stupid questions, I've been trying to find this stuff out for a while, I understand that these might be stupid questions. What happens if my hardware can support faster than 10G virtualized throughput does the vNIC bottleneck it or does some magic happen and it becomes a "virtual" Limit? Which virtual nic is fastest? I'm guessing not the E1000 as that's an emulated 1G and VMXNET3 is a 10Gig How does windows know what speed the NIC is? Thanks for that, it's been a long time since I ran a unRAID box and I want to get this right, If I create a new VM and would like it to be able to communicate with All other VMs on a vSwitch (sorry I speak windows server more than Linux) as fast as possible.ĭoes the virtio network interface show up in windows as 1G?
