YAGNI.

That's a good principle, but doesn't apply to education

Heh, indeed. Although, it somewhat does. If i'm not going to need it, its not useful to learn. If a job requires it, at that point i'd spend time learning it - quite possibly in my own time. But before then, no point.

What if you couldn't get the job without already knowing (or at least having a basic understanding of) it?

At THAT time i'd either learn this, like I did say, or not apply.

It's to late to learn it then.. they are hiring now - it might take you months or years to learn it.. by then the job is long gone.

It doesn't sit well with me to sit and learn things in my own time, taking months or years to learn, where I do not know if a job will ever arise needing it. l Like I said: YAGNI.

Why spend valuable free time with family learning something that you will possibly never ever use. Learn something when its needed and save wasted time learning something that's never needed.

Because it is fun, and it is what causes us to move forward in our professions.

Its not as fun as spending time with family. We all have our own needs from life - personally time with loved ones is top priority over learning things I may never use.

So you have absolutely no personal time where you work on hobbies, etc? That's what most are talking about here. When others might be off playing basketball, others will be playing in a lab, learning - because that's what they enjoy doing more than playing basketball.

Of course. But learning a random arbitrary IT 'thing' has no use unless that thing is needed - say at work. If that's the case, work has a responsibility to engage end provide that time, not me.

I'll agree that you shouldn't simply learn arbitrary things. You should learn things YOU are personally interested in. But if nothing interests you - why are you in IT?

I did say I've done that for the odd thing I've been interested in... but not often enough to call it a lab.

I have a laptop, but no real home lab. I have done the odd thing I've been really interested in, but not often.

IMO, if I need to learn something for work - I learn at work/on the job.
If I don't need to learn something 'IT' for work, i'm most likely not going to spend time learning it at home - I have no use for it.

^ of course, at the point it is needed for work, if, then I will learn at work as its needed.

Why spend valuable free time with family learning something that you will possibly never ever use. Learn something when its needed and save wasted time learning something that's never needed.

Because you are genuinely curious and passionate about technology? I will probably never use KVM on the job but I would like to know how to do things in it if I ever do need it. Many technologies that I implemented in my home lab I have brought to my job as a resource.

Also, as IT, we make decisions about what to use on the job. How do you know what to use at work, if you haven't been playing with it?

Research when a project comes up.

That's an insanely costly and ineffective means of doing it most of the time. I have to make decisions constantly, often in a meeting. There is no time to research, especially if I have to question things already proposed. Researching might take weeks or months and in some cases years. Decisions often have to be in minutes.

Yes, but using my OWN time to learn to is a detriment when all it does is save the COMPANY time. Sure, give me 'research days' to do this stuff or an allowance. But don't expect me to learn everything possible to learn in case 'something' comes up and needs a quick answer.

Research such things at work, for work. Home is for home.

So as a potential employer, what I hear is.... I'd have to train you for everything. Why hire someone that needs trained always, instead of someone who learns what is needed? Would you hire a lawyer that hasn't learned law yet? Or a doctor that hasn't learned medicine yet? What profession hires people who only learn the job after being hired?

Why assume somebody is applying for a job the description of duties advertised isn't a match? If I cannot do the job, i'd not apply. Of course, if I got the job and needed to learn something, I then would - as its now needed.

YAGNI.

Disconnect the VM from the virtual NIC. Reboot VM from host management. Connect to VM from host management (the VM is now not on the network). Login with domain admin creds. This will be allowed as 'offline login/admin'.

Then put the VM back on to the network whilst logged on and rejoin the VM back to the domain. Then restart. Easy.

On performance, you're right about VLANs, they're designed for security. I guess you could argue you'd reducing potential broadcast traffic, but in this situation that wouldn't matter, as the number of devices is the same. It looks more and more like the separate-network-for-server-to-server communication is unnecessary.

I didn't think they were for security...

I thought VLANs were purely for segregation of traffic to make quality of service/planning better. Yeah sure, something on VLAN1 wont interact with VLAN2... but its the same switch/hardware/cables. So I presume if I can get access to that kit with Wireshark or something id be able to get the traffic regardless of VLANs, and the fact they are VLANs wouldn't matter... Could be wrong here though (probably am)...

@eddiejennings said in Food for thought: Fixing an over-engineered environment:

@coliver
Right now, I'm planning on one host with multiple VMs. So if I had this separate, internal network, methinks performance would be better on a virtual private switch, rather than using virtual external switches bound to a physical NIC that is a part of a separate VLAN on the physical switch.

If the VMs are on the same host no need to give them internal and external virtual NICs. They will communicate over the external virtual switch, but the traffic wont go to the physical NIC/out to the LAN.

You only want internal switch between VMs where they are only supposed to talk with each other/not be on a LAN.

I'd probably back everything up. Twice. Then test restores work...
Then, i'd disk2vhd everything and verify all are working.

I'd likely then move all the 300GB SSDs in to Server 2 and provision as a Hyper-V host with Raid 5 array. Giving about 1.5TBs of space. I'd put all the VMs on to that host and run as production. (May need to revisit licensing).

Then, make server 1 Hyper-V host with 4 x 4TB drives in raid 10 (about 8TB usable or so), and setup that host to be a replica server target for server 2 VMs, with a few replica copies of each VM as it has the space. I'd probably move most RAM from Server 3 into Server 1 if its compatible.

Server 3
Get some more large drives and provision as a backup target of some form.

Or something along those lines anyway.

So, what are you going to do?

This wasn't my DPACK - I posted it for learning purposes only. The DPACK came from someone on SW.

Ahhh, I see. No worries.

Finally got around to reading about this Bad Rabbit stuff and then made a GPO to roll out cscc.dat and infpub.dat in the hope to stop any possible issue for us.

Deciding what to have for lunch. KFC, sandwich from shop, or nothing.
Big weekend of beer coming up, so probably best to have nothing as I will eat junk all weekend. Hmmm, decisions.

@scottalanmiller said in Reading a DPACK:

There is no trivial way to measure CPU performance. The simple means used here is cores times speed. This is misleading as an Intel G6 core is not the same as an Intel G8 core is not the same as an AMD core. So this can be pretty misleading. But as long as you are getting faster core architectures in the future, you know that meeting or beating the coreXspeed calc of the past is more than enough.

So you have 22GHz of cumulative performance here. Likely this means that dual quad core procs in a new server will be plenty.

Scott - Looking at this DPACK, assuming the architecture is good, would there be any reason to upgrade this system, assuming nothing is being added (load wise)?

From a capacity perspective, not at all. You are way over provisioned.

Agreed, unless you want more room to expand. Looking at the DPACK you only have 2.58% of storage left available. If the VMs have plenty of room you could take space back to put in to 'available'. But, if the VMs are full, and you cant take any back... 2.58% sounds low to me...

Free Space for the sake of free space outside of the VMs seems wasteful, unless, as you mentioned, there is expected use of that space in the nearish future.

Indeed. Agreed. So the question would be, does that space meet the realistic needs of the business in the coming 6 - 12 months? If not, you need more kit. Hence, saying what I said
