I've been pretty happy with the D510/D525 even with the limited speed,
cores, memory addressing and onboard cache. I like the low power
consumption and passive heatsinks.
What I'm looking at is Supermicro 5018A-TN4:

Not all that cheap, but it's a genuine server with ECC memory, IPMI, short
depth rackmount, and with the 2.5" HDD bracket can easily hold two SSD's for
a software RAID1 configuration. Set the fan at lowest speed and even if it
fails it should not really be needed unless you have it in a hostile
environment. Probably fine with 4MB RAM and 128GB storage, maybe more
storage for RADIUS or CACTI.
BIND does a good job of multithreading and will use however many cores you
give it, not sure about RADIUS and CACTI. D525 has 2 cores and 4 threads,
C2750 has 8 cores and 8 threads plus a somewhat higher clock speed, so I'm
figuring 2-3 times the performance? It's definitely more money though.

Subject: Re: [AFMUG] Atom D525 vs C2750
We have been planning on standing up a couple of light duty Linux servers to
upgrade our DNS and RADIUS and maybe even a CACTI upgrade later. Are these
newer ATOM platforms and a couple of small SSD's up to these tasks? How
does the D525 do?
It appears the C2750 has been out for nearly a year but I'm are not finding
too many products using them. Intel's chart makes it look like the C2550 (4
cores vs 8 cores) might be a more cost effective replacement to the D525.
But there are even fewer C2550 motherboards out there and they are not
significantly cheaper than the C2750 or even the D525. Are we just not
looking in the right places or is this low-cost low-TDP server market just
really small?

Subject: [AFMUG] Atom D525 vs C2750
I have several small Linux servers using Atom D525 processors for tasks
like DNS and
RADIUS, I even have one running Win7 that I use for PRTG and CNUT and RDP
sessions. Put a couple 128 GB SSDs in them and with passive cooling and
low TDP
you have an almost indestructible little server.
Going forward, I'm wondering if I should look at the newer C2750 version,
it would
seem to support more memory and storage, 4x as many cores, 2x as many
threads,
higher clock speed, more cache, supports ECC memory, but at a higher price
and TDP,
and the Ethernet NICs might not be as good as the 82574L chips on the
motherboards
I have been using. Also at that price point you could question the value
compared to
just using an i3 or E3 processor. And even if the D525 is an old design
with limited
cores, cache and memory addressing, it does the job, so the only reason to
use the
newer chips may be for future proofing.
So has anyone done the analysis or actually deployed C2750 based servers?
