Question 1

If I buy this model, what OS would be best suited for a small business? We would have 3 computers accessing it and at most 5 users.

Accepted Answer

Windows 2012 or Windows 2016 should be perfect with the type resource you planned to use it for. With all the RAID futures that came with it.... configuring with RAID mirror for OS drive and RAID 5 for Data storage runs super smooth. Its a robost small business machine, runs very smooth and quite and it is still my beast all my multiple servers. So no hesitation recommending to anyone.

Hope that helps.

Question 2

Does this come with an OS pre-installed?

Accepted Answer

No, this does not come with a pre-installed OS.  You will need to get a copy of MS server, or HP has a Linux based system (Clear Center) that is available on a subscription bases.  I had an old MS Server that I could have used, but choose to use the Clear Center.  It has worked well and no problems to date.

Question 3

Is this DDR4 or DDR3?
Your title is "4 x DDR4 Unbuffered (UDIMM) Slots, 64GB Max."
However, Specifications wrote DDR3.
Which is correct?

Accepted Answer

Hello,

Thank you for contacting us in regards to your question.

The best way to confirm specs is actually by checking the manufacturer's website (that's where we get them). Click on the Specifications tab on the item page, and look in the Quick Info box on the bottom of the page. You'll find a link to the item on the manufacturer's own site with the most up-to-date details.

Thank you,
