I understand, I just close the annoying dialog and go on.

I don't know how Starwind vSAN can be run but if it's on a hypervisor it's severely limited by I/O congestion through the kernel. NVMe drives is causing problems that was of no concern whatsoever with spinners. Both KVM and Xen has made a lot of work to limit their I/O latency and use polling techniques now but it's still a problem. That's why you really need SR-IOV on NVMe drives so any VM can bypass the hypervisor and just have it's own kernel to slow things down.

Anton: There are no problems with polling these days 🙂 You normally spawn a SPDK-enabled VM (Linux is unbeatable here as most of the new gen I/O development happens there) and pass thru RDMA-capable network hardware (virtual function with SR-IOV or whole card with PCIe pass-thru, this is really irrelevant...) and NMVe drives and... magic starts happening 🙂 This is how our NVMe-oF target works on ESXi & Hyper-V (KVM & Xen have no benefits here architecturally, this is where you're either wrong or I failed to get your arguments). It's possible to port SPDK into Windows user-mode but lack of NVMe and NIC polling drivers takes away all the fun: to move the same amount of data we normally use ~4x more CPU horsepower on "Pure Windows" Vs. "Linux-SPDK-VM-on-Windows" models. Microsoft is trying to bring SPDK to Windows kernel (so does VMware from what I know), but it needs a lot of work from NIC and NVMe engineers and... nobody wants to contribute. Really.

Just my $0.02 🙂

@Dashrender That's what a dedicated label printer is for. They suck even harder than standard printers, but are so nice once they're working.

OK - So we looked into that option. The departments need 10+ labels at a time. The EHR is unable to send 10 label print requests to the label printer in one click. Instead, the user has to click print 10 times. Management has said - that is unacceptable.

Therefore label printers are out.

Whooah, hold your horses here. There are plenty of label printers that could do that. You may not want to pay the price of a real label printer and you might not know that such a thing exists, but that doesn't change reality.

This is not a hardware issue. This is a EHR software issue. The vendor would need to change their software to do this - could they? likely very easily, but will they? unlikely. They only seem to care about advancing new things, not fixing, improving existing things.
