No in rack UPS?not really needed in a Colo - as it will have (well it should anyway) Dual sourced feeds, and full facility UPS / Isolation / Generator.
Had an issue a couple times, several years ago, at a colo in Los Angeles. Redundant power systems failed and the generators didn't work. Yay!! So, I guess it depends on your budget and how much up-time you really need.
I find that data centre setups tend to skimp on the power side. We find out really quick that there's a problem when there's a cascading failure that eventually wipes the whole DC out.
Such as an ATS (Automatic Transfer Switch) failure and literally blows out taking the entire DC with it.
Another was the recent Azure outage caused by lightening striking a circuit that must not have been properly protected that in turn took out the A/C then boom. This one is actually a lot more common if one pays attention to outage news.
SuperNap (Switch) in Vegas is Tier IV Platinum with true A/B/C circuits throughout the facility. All three circuits are in different parts of the DC building they feed.
We have a Tier III here in the Edmonton region that can't get Tier IV because we only have one power source in this province. They have a similar setup to Switch though only A/B with isolated circuits all the way through to the multiple N+1 generators outside.
If it's too good to be true price wise there is a very good reason why that is so.
That's why we use Colocation America in the US and 3Z in Canada. They've both been great.

Yes, the datacenter is fully redundant UPS and generators. And also on internet connections, network infrastructure, cooling etc. Good point though!After some thought, this is what I'm thinking on cabling.
- First remove cable management so no space is unused.
- Place and connect servers from the top down. Should be easier to add equipment that way.
- Make a bundle for each switch and use colors for it.
- Wire the nodes from each side and let the power cables also go to each side. I don't know if the racks have PDUs on each side though.
Are the switches logically stacked together? If so, don't forget to distribute your connections between the servers across both switches for added redundancy. Otherwise, looks good to me, as far as the hardware layout goes.

Yes, it's a real stack not just configuration stack. It will be connected like the picture below, but with two firewalls for redundancy.

We had some discussion on this here:

@scottalanmiller - I can't remember. I don't know if they are still there and I don't remember their name. This was over 10 years ago, now. They could have changed tiers since then.

Great source w great pricing on Slim Cat6 patch cables: https://www.fs.com/c/28awg-slim-patch-cables-613
Also a great source for Fiber cables.

That's awesome. Just what I was looking for.
Global supplier with great prices and lots of items in stock. Fiber patch cables and also SFP+ DAC twinax and optical modules also have great prices and it shows what they are compatible with - and lifetime warranty.

@pete-s The fs.com website is what every decent supplier should strive for.
Quantity in stock is shown clearly, no guessing needed! They tell you when the stuff will ship!! -

I saw that they also do custom orders so if I need 200 purple power cables that are exactly 5.5 ft long they can do that.
I'm already putting together my first order from them
