Good luck we've got about 100 virtual desktops deployed and are looking to do another 100 next summer. We've got a big IBM SAN and a half dozen hefty servers doing the processing.
How many compute nodes do you have? Coliver
Six right now. We're haven't gotten close to maxing then out yet. That being said these machines perform at the physical desktop level but they aren't persistent, yet, so every time someone logs in they get a new desktop.
@coliver do you use altro something like nvidia grid to boost graphical performance? Do you have SSD in your SAN? The price of the SSD for our SAN frighten me (IBM), I can buy a lot more PCIe storage for my server, enough to keep VMs replicated between two or maybe all three node. Intel enterprise PCIe SSD is now at 0,8€/Gb or less, and the performance are really top notch… not your usual two-way 8Gbit/s fibre channel!
Nope, we don't do anything graphically intensive. The machines that do cad or graphics work at still traditional desktops. We do have 15K drives and use SSDs.

I was wondering where the bottle neck for the OP is? Is it RAM, disk IO, network bandwidth.
Not sure one can suggest that you bail on VDI if you don't know the reason your VDI is slow.
For example. If your switch is bad, over saturated, then new PCs won't help everything.

I don't think our network is that bad, we have cisco sg500 and the bandwidth requirement for PCOIP is very low… maybe the storage can be the limiting resource, but sometimes… it just feel like the scheduler of the hypervisor have something better to do than serve our desktop VMs, and I haven't figured out how to obtain the performance of a real desktop. Maybe, just because the performance of an recent core i5 with plenty of ram and ssd are REALLY high by any (desktop computing) standards, so its hard to come close to that benchmark with a VDI.
-
I wonder if running DPACK for a month on both your VDI servers and say one desktop would allow you to see the differences.

Well you can't really compare 4 year old servers with HDDs to a new PC with an SSD, that's just not a fair test.
How long have you been doing VDI?
Test for you - try connecting to the VDI from a PC instead of your Zero Clients. When I ran thin clients back in 2000 they were horrible! This was with Terminal Services instead of VDI, but the concept was similar - shared resources and all. The thin clients would flash a white screen whenever the session was switching between pages on a Java or Flash website. This made Lotus Domino Web Access (don't recall real name) nearly unusable for the client.
When remoting into a Terminal Server (non Citrix) from a P2, 256 MB RAM XP machine was an awesome experience for the end user, but the thin client was nearly useless, as I said. -

I think they deliver the best experience reganding VDI…

Are you sharing compute nodes with Servers? We don't do that and it goes against the best practices that VMWare has set out.
I meant to say earlier that we use 15K drives for the VM Image and SSDs for the replica image. We have bonded 40Gb (4 10Gb ports) to each compute node and redundant 16Gb/s FC to our storage. So our system probably is a bit over built for what we are doing.

Yes, we're working on getting persistent storage, not VMs, setup for staff. Then we're looking at doing OneDrive on student machines mounted via WebDAV.
If you are able to figure out how to mount OneDrive via Webdav automagically, I'd be interested in knowing how you do it.

Sure they have, we've been in production for a few years now. We have three different labs already on it.

Old way of accessing files. Some of our users have applications (photo editing and CAD) that require dependencies and a drive letter. Right now we're testing to see if this will work for our needs. I also don't want stuff in my OneDrive to sync to my local machine and this is the easiest way to access it.

The default sync agent has the same risks with additions of onboard storage requirements. The only way you prevent the cryptolocker threat is to only access OneDrive from a web browser, which I'm all for, but that wouldn't meet our needs.

Yeah, this is true.
However, in a VDI scenario, you don't want to have user files needing to syncing. every time they log in. The fact that it is one drive also helps in that you can do file versioning there, right?

Because the normal one drive client tries to sync all the files in your one drive account down to your local machine. Generally this is not a good way to do things where non-persistent VDI is involved.
