on remote reboot switches that will allow us to cycle power on two plugs at once for use with servers that have redundant power supplies.
Brands and models welcome. We should also be able to access the units remotely to cycle power.
do dual power supplies use more power than a single supply?
E.g. Say I have a server than uses two amps, powered by a single power supply. Now if I switch to a dual supply (and say each supply has the same efficiency rating as the single), does my server use more power? How much more?
My simple view of this is that it probably does, but maybe not much. The second power supply consumes some power itself, but since its not under load, it doesn't consume much. Therefore, my server with redundant supplies might use 2.1A or 2.2A.
at getting PDUs for the new facility where we plan to move our servers to. Our cabinet will have 2*20a circuits, so we're thinking of getting 2 APC PDUs (1 per circuit). Some offer remote reboot capability.
Our servers (Dell PowerEdge) have dual power supplies, and I assume the best thing is to plug one power supply into each circuit, so things stay up even if a circuit fails.
So, how would this work if we want to reboot? The servers can run on only one power supply, so does that mean we have to click reboot on the web interface of each PDU at exactly the same time?
I've never worked with PDUs before.. just cheap power strips and a call to the datacenter
I was suggested to post my q in colo forum (it was posted in hosting lounge).

View 5 Replies View RelatedI have read all the recomendations about the APC 793* series of PDU's. I have bought 2 but I cannot figure out how they do the powering off/on of ports. I did see some reference to mib's but haven't been able to figure out how to use them.

There are several 2U chassis that are listed as having 700W redundant power supplies. I thought this meant that there are 2 power supply modules, each rated to 700W.
However, if you look at the power supply matrix here:

Under 2U, the options for redundant power supplies are 500+500W or 400+400W or 350+350W. Does this mean that each individual power supply is only rated to half of the total power. For example, 700W redundant power supply = 2x350W individual power supplies?
Let me start by saying that we use redundant power supplies for all of our core service nodes, however I am wondering about the failure rate others have experienced.
I have been in the industry for nearly 4 years now, and have yet to see a power supply failure, so I'm considering just going with single power supplies instead of redundant.
Currently we are running some equipment on a 208v 30amp circuit and using APC step down transformers to take it to 110v.
All the servers running on that circuit are Dell PE1950's so they are pretty new. There is also a newer dell switch and a Cisco Pix 515E on there.
I am getting rid of the step down transformers and everything that I have read says that all the PSU's are auto switching and there will be no problem with them running off of straight 208v power without any step down taking place.
Does anyone know of a fairly low cost dual power supply Ethernet switch. Nothing fancy is needed, just a simple 12-24 port switch that has redundant power features.
Our router and four little servers all have dual power supplies. Two big UPS units in a redundant setup would work great for us. The only weak link in the setup is the switch.
I can't find how to swith my Plesk into PowerUser mode. There is no such menu in Tools & Settings -> Interface Management. This is what I see:

View 11 Replies View RelatedIs it possible to use a APC remote reboot power strip for a server in a blade?
Like for example, say there are 16 servers in a blade, can you remote reboot them individually?
Because blade servers have only like 3-4 redundant power supplies and I am assuming all the 16 servers are powered by the onboard power supplies in the blade enclosure. So...if thats the case, how is it possible to reboot each individual server?

Like you know how softlayer and ev1 servers do.
Like write a small php script to access the power strip and execute the orders. May be an API or something.

Q1.) How long do additional Ip's take normally?
Q2.) How long do remote reboot details take normally?

What is a good value IP remote rebooter? Looking for one I can place in a cabinet, hopefully to control 12-16 servers.
It needs to allow me to create users and assign them to manage X ports on. If it has KVM IP it would be a plus.
