For at least 5 years (I honestly don’t recall when I put the box together…) there’s a been an Antec Mini P180 purring under my desk. This machine has been running various flavors & versions of Linux, mainly performing as KVM host.
This box contains 4 hard drives, and a Intel Q9400S CPU. (For those who don’t recall: the ‘S’ suffix means lower powered (65W TDP instead of 95W TDP).

For a while I’ve been considering replacing this unit. The replacement has to be equally quiet, good for at least 5 years to come, and easy expandable. And… dual CPU, if possible.
There are not many PC producers who build dual CPU workstations. There’s the Dell Precision Tower 7810, the HP Z820 and… Supermicro.

Supermicro SYS-7048A-T
Supermicro X10DAi
And Supermicro is where I ended up. I was first eyeballing the 7047A-T, but was then informed about the Supermicro 7048A-T which has just been released.

After some debating with myself I decided on the following specs:

 
name
amount
prod. nr.
CPUIntel® Xeon® Processor E5-2620 v32CM8064401831400
RAMSamsung 8GB DDR4 2133MHz 1Gx4 ECC/Reg 1,2V8M393A1G40DB0-CPB
StorageIntel SSD DC S3500 - 80GB 2.5" MLC SATA 6Gb/s 7.0mm2SSDSC2BB080G4
VideoSapphire Radeon HD 5450 1GB DDR3
PCI-Express 2.0, DVI-I, HDMI, VGA, Lite-Retail, w/ LP bracket
111166-02-20R

I’ll be slapping some of my existing hard drives in there, but I haven’t decided yet on how many or in what configuration so the final storage space is pending.
This new system will have 4x the amount of RAM of my previous system and it will be at least twice as fast (due to it being a 2 CPU system).

The order has been placed with the good people at Nextron, and they expect to ship it on September 19th.

The only thing I’m not 100% sure of yet is how quiet it is… All Supermicro says is: ‘Whisper Quiet Workstation’. Does anyone know how loud the Supermicro employees whisper? :cool:

Actually, the title of this posting is bit inaccurate… There is no vs. when it comes to operating systems. All there is is an and!

Almost every day I run into people who are… narrow-minded, for the lack of a better word.

Narrow-minded, because they approach the whole thing backwards. They first set their mind on a specific OS, and then they look at what the options are to deal with the project at hand.

Wrong, wrong, wrong…! You first look at what the best way is to deal with the situation at hand, and then you use the operating system that application runs best on!
Both Microsoft Windows and Linux (and Mac OS X, OpenSolaris, IRIX, etc etc) have their strong and their weak sides.
However, if I were to start summing them up here, this posting would…

So the next time you have to make a choice on the right software for a project, look at your resources (budget, hardware, etc) and then first find the right application for your needs.
Once you have that, there is a good chance it simply runs on only 1 OS.
If this is not the case, then and only then, you can start making operating system choices.

Apple, Linux and Microsoft
And don’t worry about ending up with a mixed environment. I know from long experience that in quite some cases Microsoft & Linux talk better together than Microsoft & Microsoft, or Linux & Linux for that matter. :roll:

To sum up: Computers and operating systems work well together, so you can and should go for the best of both worlds.

(It’s not like the whole Star Trek vs. Star Wars discussion where there is a clear winner) ;-)

Well, I can now finally answer the question I asked myself in an earlier post, about what it would take for me to switch jobs.
The answer turns out to be… location, location, location! Last week I got a job offer from Omnicom AS in Sarpsborg. The offices of this company are located 15 minutes walking from my house. Quite a difference from my current situation where I spend about 3 hours a day between house and office.

I have worked with/for some of the people there before, in my days at Respond AS, back in 2000-2002 and I guess they were satisfied with the work I did back then! ;-)

It will be a bit of a switch, from the current Linux-based R&D environment to a Microsoft-based production environment, but that is a challenge I’m up to!

I’ll be starting my new job as ‘IT-sjef’ on September 1st.
