DCO Power Reserved By Group

DCIM_Support · ‎2020-07-03

Hi All,

I'm trying to figure out what the power "reserved by group" is in DCO.

Can I change this or can someone explain why it is so high on some racks?

Thanks

Hi Matt

The 'Reserved by group' is the when other racks in the same capacity group uses more power than the planned average for the group.

For example: One group with four racks, the total capacity of the group is 20 kW and each rack has a planned average of 5 kW. If some rack goes above 5 kW at least of the other racks have to use less than 5 kW of power.

You can also see a bit more about capacity groups here: Working with Capacity Groups

I cannot see directly from the screenshot why the 'Reserved by group' amount is so high on the specific rack.

Also note that for the next version of Data Center Operation we are trying to simplify the capacity management.

Best,

Niels

Hi Niels, Thank you for that, I understand a bit better now 🙂 Can you see the attached image? It looks as if there is one capacity group in the DC1 area, however the reserved space is not equal in racks... Is there any way to re-distribute this? Thanks Matt

Hi Matt There are two main things to check: 1. The reservations are made per phase, so if the racks are only supplied by one or two phases the reservations can be different on different racks. 2. The reservation made is depending on the remaining capacity of each of the racks. So a rack with a lot of capacity has a bigger reservation that a rack with only a little capacity left. From the screenshots my guess is that you have an overloaded phase in the model. You can enable a detailed view (per phase) by enabling more detailed tooltips in the Preferences. Look under: Preferences -> General -> Tooltips and then enable 'Advanced Power'

Thank you for this. You are correct it appears that the L2 phase would be overloaded in our model.
