Switched Metered Power Distribution With Port-Level Current Monitoring
Can anyone recommend PDU make/models that has port-level current monitoring (via SNMP would be great)? I was looking at APC PDUs and found little documentation regarding the level of current monitoring.
Also, would anyone happen to know the maximum number of user accounts I can have per PDU?

Liebert's new PDU's have the power monitoring per port and they are decently priced as well.

I took a look at Liebert and they look might good for the price, as you've mentioned.

I believe the new APC 8000 series PDU's have this ability. Although, the switched models are not available until Nov. 2010.

For standard 20Amp 120V circuits Tripp Lite pdumh20atnet is fairly inexpensive. All in should cost you around $400 and it is a 1U device.

Looks like the Liebert MPH PDU does not support multiple users, it seems to have only 2 fixed accounts. I forgot to mention that having per-port ACL would be great.

Try the Raritan power bars. They're based off the dominion KVM switches I believe, aka you chain it through one of the 16/32/64 KVM ports.
From what I've been told, they do per-port power monitoring, plus then you have a very nice high end, multiuser KVM to play with as well .Myles Loosley-Millman - admin@prioritycolo.com

I've talked to APC and they told me that the next-gen PDUs does not support outlet-level monitoring.

Yes, you are correct that it will be available in Nov 2010 but it will not have outlet-level monitoring, only per breaker bank.
Thank you for contacting APC's email support on 09/11/2010 01:22 PM. I would be happy to assist you.
Our current model PDU's do not have this ability to monitor current for each outlet.
The new PDU's that will be available in October - November timeframe will be able Monitor aggregate current consumption for each phase and/or each breaker bank via local display or remote network.
This is still not for each individual outlet though

I'll double check with APC then as I spoke to them in person, and they clearly stated that it would include monitoring per port.

Have you considered Server Technology? They have this type of solution, and have been doing Rack-level-Power for 27 years. It apears to be their core focus

You may want to cont them directly. I believe you will also require the input cord.

I asked APC to clarify regarding the Outlet-level monitoring in gen2, now they are saying it will be available next year:
Response (John) - 09/15/2010 09:30 AM
Thank you for the update.
I contacted one of our senior engineers about this feature, individual outlet current monitoring.
They said only a few of the new generation 2 switched rack PDU's will have this feature.
They will not be released until next year so I do not have any part numbers of the specific PDU's that will have this feature till then.
I would say to please contact us again in January for more information about this feature and exactly what models will support it.
Thank you for thinking of APC for your product needs and have a great day.

The Raritans are really great, but a bit pricey. I'm using them on 230v in the UK, they tell you per port power use (in amps and watts), per port power factor, accurate to a really small value. the Triplites I use in the US on 120v get the job done, but certainly are not as accurate (only displays to the nearest amp, and I'm really not confident that it's accurate to within 1/2 amp either) and don't do per outlet monitoring. So the raritan is great if you need what you say you're needing. If you'd like to save a ton of money, the Triplite is a solid option, does it's job, just not as "nice".

My understanding is that Raritan has only been doing rack level power for less than 2 yearsand still refining their overall Technology. Were you able to reach the folks at STI? I believe they will actually let you eval their units as well.............

I haven't had the chance to talk to STI yet. Raritan looks pretty impressive, esp. with their +-1% accuracy.
Does anyone know the difference between Raritan's DPXS20-20L and PX-5802T other than the port counts?

We just bought a bunch of Avocent PDU for specifically for being able to measure the output of each port. They are more expensive than APC's, but well worth it.
