Every private colocation rack contains a free PDU (power strip) with many power ports like C13, Shuko, and C19 connections. Users can use it or replace it with their own PDU. Every PDU is minimally connected to N+1 non-break power. Although the Serverius datacenters contain a few types of PDU models, in general, they will always be the same:
- A third or half private rack is using a 16Amp AC 230 volt PDU's and provides C13 power connection to the racked hardware.
- A full private rack is using general a 32Amp AC 230 volt PDU's with 2 groups of 16Amp with C13 and C19 power connection to the racked hardware.
The third and half racks are connected to 16 Amp CEE plug and the Full Private racks are connected to 32 Amp CEE plug (air-cooled, under the floor). If you like, you can connect your own purchased PDU directly to it.
Each PDU has its own (set) power breaker before it's connected to the main power rail. The 32Amp PDU's also contain power breakers. This will prevent the whole PDU from going down when a racked server device causes a power short circuit.
- The maximum peak power use for each third/half private rack PDU is 16 Ampere. We advise our users never to use more than 13 Amps in general.
- The maximum peak power use for each full private rack PDU is 32 Ampere. We advise our users never to use more than 28 Amps in general.
- Keep in mind that racked hardware will use more power during startup, much more than running normally. During startup/booting the max peak power should not reach above the PDU its maximum!
- All PDU's should only be used to connect to your computer hardware. Other PDU connections are forbidden.
- The maximum use for each C13 outlet is 10 Ampere. However, Serverius advised not to use more than 8 Ampere.
- The maximum use for each Shuko outlet is 16 Ampere. However, Serverius advised not to use more than 12 amperes.
- The maximum use for each C19 outlet is 16 Ampere. However, Serverius advised not to use more than 12 amperes.
- In a full rack, most PDU's are divided into two groups. Named: "Group 1 & Group 2". Both groups are provided with 16Amp thermal fuses or power breakers.
- Power cables from the PDU to the computer hardware should be "datacenter ready". If it's unclear, users should not use them.
- if a PDU fuse or breaker from a group is triggered, first unplug ALL racked hardware before replacing/enabling the fuse/breaker. Secondly, enable all hardware one by one.
When you need more power than the PDU can handle, in most cases you can order a second PDU mounted to your rack.
