The 730 will be more efficient based on improvements to the chip design but also DDR4 uses less power than DDR3. There's also increase in efficiency when with the v4s over the 3s

The newer chips improve efficiency in two areas. a) what they do per clock cycle (IPC) and b) power consumption at low load or idle.

Chips like the v3/v4 in the 13th gen do lag on IPC but also on pure clock speed but for most homelab servers that doesn't matter because they're not heavily loaded. It's the power consumption for idle where they get crucified and yes the Xeon will use a lower more power to tick over.

There could also be a design factor there. It's okay if your desktop goes into a deep sleep to save power but for a server responsiveness is a big factor and you don't know when there's going to be access so going in really low power mode isn't a good thing because the time to come back to full power could be critical.

if you search for online power consumption caculator such as one used for sizing a a UPS you can play with different configurations and see what numbers you come up with.

And yes easily $70 more to run the 710.

But there can also be other factors. Each of the those HDDs can consume between 5 and 10w depending if they're idle or in use. Each memory module will use 2 - 3w so if you've 8 x 8GB in the Dell server that's 24w, where as say 4 x 16GB would use half that.

Your Dell also has iDrac so even if the server is shutdown, unless it's unplugged you'll still draw some power.

And speaking of power, the PSU effeciency has greatly improved over time. Not sure what standard PSUs Dell provided with the 710 and whether they improved them to 730 but there's a good chance your desktop has a more efficient unit.

Next time you copy over 1TB you might start off with "Wow" before hitting the "Yawn".

Caching is good until you fill the cache and then everything drops back to normal.

But with smaller files you probably will notice a difference

Not sure what you're trying to do - Thunderbolt can be daisy chained so not sure why would need to put a TB card in the dock.

The enclosure is generally transparent to the OS. It just sees the devices plugged.

TechnoTim on youtube a video on rack mounting his Mac Mini (M1 model) and used an external chassis and tried different cards without issue.

You're probably going to limited by Apple's support (for example you can't put in a nVidia graphics card in).

google to find a power usage calculator (often used for sizing a UPS) that will help you.

You also need to factor in other components - motherboard and chipset, each RAM stick uses 2 - 3w you've got system fans and inefficiencies in the PSU.

might have to check & confirm but you could probably put a high end V4 xeon in there that will give you lots of cores and ram is always that helpful.

Being the old DDR4 components you could probably pick both up for little $$$$ via ebay.

Now both that and the i9 system are massive over kill going by your current load.

Normal wisdom is that the modern consumer chips is the i9 are the way to go because they'll perform better and use less powert (especially if the system load is load or pretty much at idle).

Your i7 system out performs the 1620v3 and uses less power in doing so.

But what you've got at the moment is as far as that platform goes other than perhaps a faster processor,

So then we look at the return on investment. Find an online power calculator and work out the running cost on the T5810.

Then look at the cost of the new motherboard/CPU/ram (if the Dell is using RDIMMS you can't carry them over the i7 is DDR3) and probably a new case.

Though a new case would give new drive bays - that T5810 seems rather lacking unless there's more hidden away than just the two at the bottom.

Then work out the running cost for a new system.

Then comparing the two work out how long it would take you to recover the costs of the new components based on power savings.

Anything over 2 years, stick the dell and upgrade down the track.

MS AD - well it just works and if you're looking to learn for industry experience it's the one to go for. Spin up a Windows Server trial edition, re-arm the trial every 180 days and have it running for nearly 3 years. Just before the trial expires completely you migrate the domain to a new install and continue on for another 3 years.

Running Samba-AD. It has it's issues and can be painful but seem stable enough.

Never gotten in to FreeIPA. If you're needing Windows authentication, it's not the one for you.

:)

you're correct in what you've you done but there could be other factors.

Your ISP may have locked the connection so they expect it to come from their router rather than yours.

Or you might need to to leave the connection down for a period of time and the connect so it accepts things coming from a new MAC address.

Don't set the IP to static unless you've been allocated one - that can seriously cause issues.

otherwise providing details such as your current cable equipment and ISP might help people come up with a solution.

find an online calculator used for determining a UPS size (google will help).

That will give you an indication on how power the system will use.

then calculate based on your electricity price (thin there are online calculators that will do that as well).

Yes they would make a psu that was specific to a single model.

Any compatible/optimal e.g higher capacity would be listed in the technical documentation.
