@flomer I would say this is a post-sales matter so I would go that route. You bought something and it is not performing to your expectations. Is it a hardware problem, software configuration or did you buy the wrong thing? It doesn't matter - you paid big money for it so get the vendor to sort it out.

That's not at all how it works. Try buying a Chevy car and going to the dealer "I paid a lot of money and it doesn't haul eight people, you have to fix it." Clearly it was your job to evaluate your workload and determine your needs. And "a lot of money" is subjective.

There is no one involved in this equation responsible for knowing the workload and performance characteristics except for the end user. Unless the procs aren't working correctly, the percentage of responsibility on the vendor would be zero.

This conversation is no different for the hundreds of others we'd had and seen - many industries and businesses do not care about their IT, and never keep modern - Look at my CAT scan machine installed in 2008 that came with Windows 2000, or a print businesses print server coming with XP in 2010.

As Scott reminded me again yesterday - it's not our responsibility to care more about the business than the business drivers/owners.

Even so, I just can't help that, I want things I'm involved with to be better.

Well, the main application itself, is a "server" that is started automatically as a service. It gathers data and performs calculations based on the input. Data may be exported, but not always, but stored in proprietary databases. The user interface comes up by way of Interactive Services Detection, and is a bit of a pain... The application is being rewritten as we speak and will use HTML and a browser for GUI in the next version. BUT, the customer is only allowing RDP traffic to the server, not http, so...

Just one customer or most or all? If it is just a few... that's their own issue, right? If they refuse secure HTTPS and demand RDP... sure. But that's on their end, not your end. Why get involved, right?

OK, I guess I could try and test it if I have the time soon 😉

Did you get a chance to test?

@scottalanmiller I was simply using those numbers as examples, actually. I have learned over the years that it's better to start low and increase as the VM needs more resources.

I often try to estimate just a tiny bit high, look at the real needs when given available overhead and tune down.

Example: Give a PBX 1GB of RAM. Watch the real usage as well as caching and buffering over time. Then decrease until caching and buffering have enough overhead but only just enough. On a typical PBX this means we decrease to around 800MB.

But what is wrong with the first logical drive?

That would be the question. What makes you feel that something is wrong?
