P Class enclosure removal

We currently have a fully stacked p class blade infrastructure

6 x Enclosure
2 x Mini bus bars
2 x 3U Power supplies
Running on 3 phase

We need to remove half of this kit as we need the space.

Does anyone know if we can remove this safely and keeping the kit in a supported configuration?

Re: P Class enclosure removal

It's been a while since I used the mini bus bars, but if I remember correctly they support 3 enclosures. So if 1 3u power unit is going to a set of mini bus bars which in turn are connected to 3 enclosures, then yes, you can remove half.

Re: P Class enclosure removal

Hi,

I think you can do this.

Mini bus bars support up to 3 enclosures.

You can use this tool to check if 1 3U power enclosure will provide enough power to the 3 server enclosures :

You can check

for more info

If you have enhanced backplane HP recommends using 2 power enclosures for redundancy...

BR,

Re: P Class enclosure removal

hi

the link above is destroyed, but now when I think, if the 2 power enclosures provide enough power to the 6 enclosures, then 1 will take the half of the load.

Re: P Class enclosure removal

How about if i needed to remove 2 enclosures do you think that might be supported?

Re: P Class enclosure removal

You can't use 1 mini bus bar to deliver power to 4 server enclosures(max 3). Further 1 Power enclosure will be not enough to handle 4 server enclosures.
