we already have these VMs hosted in a 4-node flexpod environment (if vmware enterprise plus is an overkill for us, then how would you judge flexpod???).
This is unfortunate. Kind of the "worst of the worst". There is no way to really sugar coat this. It's the worst hardware on the market (Cisco), with a rather poor storage layer (NetApp), with an unnecessarily expensive hypervisor (VMware) where you end up with really, really high cost and hardware/setup that many of us would want to just throw in the trash.
Does it work? Well, kinda. Chances are the cost of this one purchase alone would have paid to hire an IT department to solve the bigger problems and implement a simpler, more efficient, more reliable solution that addresses your needs, rather than just empties your coffers.
This is, unfortunately, a setup designed specifically to prey on companies that think that they have to buy "products" instead of expertise and that they can skip IT. But it doesn't work that way. To quote VMware themselves "high availability is something you do, not something that you buy." Even the companies that sell this product don't believe that this is in any way a substitute for getting access to IT resources that are going to look at your needs and engineer a solution based around them.
We all understand that this means that you have now already purchased all of this and that there is no way to fix that. The only thing you can do now is look at the scale of this mistake and use it as a learning exercise to go back to your company and try to address the broken thought processes that brought them to what should have been an obvious "never do this" scenario. This suggests that they likely do the text book "never do this in business" things of engaging sales people, resellers and the vendors asking how they can spend money rather than getting business experts to actually figure out what the needs are, and what would address them. The goal had to be "how do we spend money", not "how do we solve a business need." There is a massive opportunity for improvement here, but it won't help until "next time." but there will be a next time, so this lesson is insanely important to learn.
That said, though, you are asking how to fix this. You've figured out that this setup isn't good. That's the first step. You know that you need reliable storage instead of the RAID 4 NAS device single point of failure, that's good. I would step all the way back and consider all of it a waste and look at "how best to move forward" based on what you own, and try to remove IT's emotions from it because it is what it is, and those emotions will only hurt the company (and IT itself) long term.
apart from the tremendous contribution from a generic point of view, would you suggest a 2-node setup with local datastores and a fast network and that's it, given that we take as proper backups as possible
? BTW we also have veeam B & R standard edition.
what about the vmware SRM? what do you think of it?
