8GB of RAM on my laptop, and an SSD
Should I use even consider having a swap partition?
Seriously, most RAM I managed to hit under realistic usage was around 2GB for pure web browsing, and 6GB for web browsing, heavy VM and other stuff - the CPU can't even run enough shit to hit 8GB, and if I for some reason lose all reason and decide to do a 20GiB version of brt, I can create a temporary swapfile without needing a whole separate partition.
Only use cases I can think for swap is running something seriously heavy, and hibernate, and I seriously don't use hibernate, I either poweroff or suspend.

limit the swap to 4GB if it is a corporate laptop
[QUOTE=JohnFisher89;44407660]limit the swap to 4GB if it is a corporate laptop[/QUOTE]
Why? And it's a personal laptop.
4GB sounds incredibly arbitrary, it's not enough to hibernate safely and I can't think of anything that would require 8GB RAM + 4GB swap

Anything over 8gb RAM doesen't really need any Swap space.
Unless you have some application that does consume hilarious amounts of RAM.
I'm going with no swap, I don't have to complicate the setup with Logical Volume Manager if I don't have a swap partition.

4GB is the most that corporate (32)bit programs run, namely outlook
I have a little swap set up so that some programs wouldn't fuck up over no swap.
Personally I go with a 2048mb Swap file on my Linux installations.

Sadly no corporations use linux other than zero clients and webhosters
Might be more used as webapps and VDI incorporates linux though

Other than vApps a 70k+ job; The amount of environments that use anything other than RHEL is small dude.

that's cool but do you support nearly .75 million clients?
Centos owns but there is a cost analysis any good IT person should raise when the IT department talks about value to the company MySQL, PostGRE, and NoSQL is cool but who do you call when shit goes south?
You need to think about what the company loses in an outage not "how cheap we can do it"

I've seen so many Debian and CentOS servers, that I can gladly say this is false.
Actually, I have only seen a RHEL installation once in a corporate environment., and it was a workstation.

SMB is hell. I am sorry in advance. When you work as a consultant and IT analysis let me know.
I've seen red hat, centos, and debian distros back to 2001. You want to know what the cost of them paying me vs. paying a simple RHEL+support distro for upgrades was?

Not my decision. Thats the decision of the Management to decide which is more important. I merely have to work with the resources that they provide me with, and do the best with it.
Basically it was like "why would we pay thousands of $$ when the can get the same thing for free?".
At work, I in combination with my Co-Worker are the first line of defense. We usually manage this shit alone. When shit goes south we usually hire another firm to give support. This has only happened once in around 4 years.
Also, the DB Server does not support 750 thousand clients, but the Server in combination with our Webshop I maintain generates millions in revenue.
Considering you're arguing that Linux isn't used in businesses, I wouldn't trust you enough to hire you as a consultant.

I currently am an IT aprentice (Software Developer) in my last year (Currently in my finals), and I can say it's not fun and games.
We are 3 People in IT. Me, the other Aprentice and my Boss.
My boss doesen't really have much IT knowledge, unless it's about MSDOS and tech in that timespan, and my Other aprentice is in his first year, so he knows nothing except a bit of MS-Word etc...

The one thing that I find really positive about my Workplace is that my CEO really knows his shit, when it comes to technology.
Also he really knows Linux and uses it on his main machine, which is really surprising.
What is going on right now? This is a shit show. Linux's usage is WILDLY VARIABLE. It's not "It's used" or "It's not used" it's "It's used in X by a good amount but not in Y". It depends entirely on the market and industry, and both of you talking from personal experience is absolutely horrendous. That's not a good way to sample for an overall, at all.
You think someone would just do that, go on the internet and talk about stuff they're not well informed about?

Is there a statistic about Linux "Market Share" in corporate environments? just wondering.

The best you'll get is from the IDC.

They measure via OS installed on the box as it's sold. It's the most accurate method you're going to find.
[QUOTE=B!N4RY;44405703]Don't use software RAID.[/QUOTE]
Can you give reasons for not using software raid?
Personally, I'm still struggling with 2 GB DDR2. I remember when I had single core cpu and 1 gb, then when I had a chance to upgrade it felt so fast... now it feels slow, I grew out of it pretty soon.
[QUOTE=benjojo;44408380]Can you give reasons for not using software raid?[/QUOTE]It's slower and takes up CPU cycles.
Really annoying how Office 2013 doesn't show you a progress bar when it's updating or anything of the sort. It also doesn't say what update it is either.

I'm arguing there is a risk involved when things are down.
Sorry I am attuned to when shit is down a second equals thousands of dollars.

If you have downtime, it doesen't matter if you have an expensive contract with a support company.
Something has happened that should not happen, and thats not a good thing.
To prevent downtime, we have as much as possible of our infrastructure as Virtual Machines mirrored on 2 separate Hypervisors each, which also have a RAID in place.

... Why would shit [I]be[/I] down?
If you're dealing with large companies, there's a thing called redundancy, and systems don't tend to go down unless someone makes a change, or there's a hardware problem.
A RHEL6 box sitting in a rack serving MySQL isn't going to just mysteriously go down, and even if it does, you should have a fallback in a large company, which you claim to usually work for, instead of small businesses.
[QUOTE=RoboChimp;44408434]It's slower and takes up CPU cycles.[/QUOTE]
Hardware raid can fail in interesting ways though.
The CPU cycles thing is fairly negligible unless you are powering a insane amount of drives.
I am presuming you are talking about RAID 1 ofc. If you are going for RAID 0 then I guess thats a whole new world of PC tuning.
