No, you don't need allflash - but it depends how many users. If you deploy 'desktop just in time' then all vdi instances are in RAM (with small footprint on the storage). Allflash is recommended but not required. It's recommended to have separate storage for VDI solution. Look at vmware.com site - they have great documents and videos how it works.

If a customer needs to eliminate physical desktops and their maintenance with a requirement of not less than 40-50 desktops then Virtual desktops would be a good option collectively.


VDI is also being used where clients need to access their "application any where" or "application mobility" or "work from home" is required.


The infrastructure that provisions, manages and maintains Virtual desktops is known as VDI or Virtual desktop infrastructure. VDI is basically desktop based virtualization.


VDI:


Compute&Storage Layer


Virtualization&Networking Layer


Desktop Layer/Session Manager (VDI software)


Security Layer


End-client/Thin/Thik Clients/Software based clients


If a customer needs VDI and Database(Oracle/SQL/MS-Exchange) as VM(s) then All-Flash based VDI solutions should be selected.This would called VDI with server based virtualization.


For VDI and Server based virtualization there are solutions available specifically made for this need. HCI(Hyper Converged infrastructure) solutions would be a better choice for both VDI and server based virtualization. All-flash back-end storage will be required if very high storage I/O or Databases are involved.

VDI uses a server solution for virtual desktops. This way the horsepower needed to run applications comes from the server-side and not the client-side.

This enables a couple of main things: a similar desktop experience for the end-user no matter where they are and what hardware they are using, and cost savings on the hardware required for the end-user. It enables patching and security benefits as well. The drawbacks are bandwidth requirements and server infrastructure cost. Using an all-flash storage array would help in the IO limitations of the server because any storage requests would be fulfilled quickly.

Pros: consistency in all desktops (they are all the same), speed and performance, patching and security, easier upgrades, lower desktop machine cost, server maintenance.

Cons: high server hardware requirements, server storage cost is higher, need a higher bandwidth between server and desktop, server maintenance.
Any kind of decision to use VDI needs to consider the cost benefit. Would using a virtual desktop be worth it? You decide.

VDI is a server farm for virtualizing dedicated user desktops. Detailed information can be found at this link, for example, VMware https://www.vmware.com/topics/glossary/content/virtual-desktop-infrastructure-vdi

How does VDI work?
In the case of my organization for 2 thousand. 20 TB data has been reserved. VDI solutions have a large data reduction (deduplication and compression, up to 20: 1). If the data is reproducible, this factor may be even higher.

Is All-Flash required or can it work on other memory arrays?
VDI can work on hybrid arrays, but they are not so efficient in boot storm, non-Vistist, VDI, reboot of the whole farm, low response times below 1ms, requirements of similar experiments as on PC.

Very good question, but a world is opened when speaking about VDI. I think that flexibility and ready to use are the most importat aspects. All-Flash in not required but it depends on the answer you get to "what should VDI use for"?

Do you mean Virtual Desktop Infrastructure? If so, then it has no relation to flash storage. VDI can work on any storage. But it will be faster using flash storage.

I don´t think that the answer for this - very general question - what vdi is, is that simple! Of course you can always give answers by definition makes on Wikipedia, or from companies which are selling vdi-solutions. But the mainpoint, in my opinion, is always the perspective of the asking person. vdi can be the simple virtualization of clientsystems - but vdi can also be the "hardcore" virtualization of extreme workstation, clientsystems, or just something between, something with application streaming etc. etc.
So it is not that simple to answer the first question. And … than out of this the result for the second question is not that simple either. Of course all of us can say - nothing is better for displacement then get more displacement. So of course you can slay al kinds of workloads with the power of all-flash - but is it every time necassery? I don´t think so. Is it every time economic? I don´t think so. So first of all - talk much more precise to your customer and try to reach his painpoints, so you can decide if VDI is really necessary, and how you have to design a new storage implementation to fit the conditions of the customer best.

Regarding VDI solution, Yes you have to get a full flash storage solution because you will have high IO, need high bandwidth, for a small capacity. Only flash storage responses time has the right solution.

Hmm, this is tough. You wouldn't have enough granularity to get you close to an optimized solution. Your best bet will be to document at least your top 10 requirements for compute and storage, then use that to identify plausible options to explore. So for compute, for example, what kind of processing do you do, will it be just for office work or server workloads; if server workloads, what type of workloads are they, and so on and so forth. For storage, what will be your needs, file or block, high transaction rate, replication requirements, do you need an object, so many questions.  Sorry, I can't be of more help, however, all I am saying is you need refined requirements.

Ben, what you are talking about are advanced selling skills. A bit much to provide you an answer, so I will paraphrase as best I can. You need to understand in-depth, several aspects of the customer's problems you are attempting to solve from their perspective: 1. How are they solving those problems now? Make no mistake, they are solving them in some way. It may be with spit, chewing gum, and baling wire, but they're solving them. 2. Where does the current solution fall short and when does it hit the wall? 3. Why are other solutions inadequate, too costly, unsustainable, or all 3? 4. How is your solution a better fit in solving those problems now and in the future? The key is in the questions you ask. Remember none of us buy logically. We always make buying decisions emotionally and justify them with logic. No one buys on price. We reject on price when it does not match the value. Price is an issue when the prospect cannot distinguish between different solutions.  There are always different factors in the buying decision. Your organization's job is to show how other solutions will not achieve what they need or want based on all of their parameters, requirements, considerations, etc., but yours will. You must spend more time talking about the problem you're solving than the solution you're selling. You are driving their self-induced anxiety about their problem and making the devil they know worse than the devil they don't. As to the specific situation you described. Keep in mind that IT pros are very risk-averse. They will over-provision and overbuy to cover themselves. A typical IT philosophy is "it's better to have the resources you may not need than to need the resources you do not have." Remember, it's emotional. No one wants to be caught with their pants down. By over-buying, they give themselves headroom for the unexpected.  There are methodologies to deal with this. Several vendors have implemented cloud-like on-demand elasticity and pricing where the customer can automatically utilize more resources that are on their premises and only pay for what they use. Dell, HPE, Pure Storage, Infinidat, NetApp all have programs like this today. And more vendors are following. This is one of the driving forces behind public clouds. Sorry for being so long-winded here. This is a complicated discussion that takes more than a short answer. Good luck.

NetApp AFF/FAS (or OEM Lenovo DM series), with no doubt, is the best answer.  SVM provides total customer isolation; it's able to run FC/iSCSI/NVMe SAN. CIFS/NFS NAS, object S3 from one box.  It's able to scale up and out. It is possible to combine All-Flash and Hybrid models in one scale-out cluster. Not supported to combine Lenovo and Netapp models in one cluster.  -Ontap Select for VMware ESX or KVM -Able to run on all the big 3 cloud hyperscalers.  Search for data fabric strategy.
