Corrugated cardboard sounds like a bad idea to me, the fibres might clog CRAC filters, etc. Why not try corrugated plastic? ~Henry
Re: [uknof] Airflow management blanks
I always thought the data centre did provide them. The reason for fitting blanking plates is to keep the cold aisle cold and make the hot aisle hot. That increases the delta T across the cooling coils and thereby increases the efficiency of the cooling plant. So the winner is the data centre, who gets lower electricity bills. The customer doesn't see or pay the cooling electricity costs, so doesn't really care. All the benefit goes to the data centre, so the data centre should both provide them and insist they get fitted. If the customer takes them out to make his life easier for fitting kit or running cables, a good data centre will put them back (although if the customer keeps doing that, he might get a bill). -Original Message- From: uknof [mailto:uknof-boun...@lists.uknof.org.uk] On Behalf Of Brandon Butterworth Sent: 28 April 2015 20:14 To: Martin Hannigan Cc: Keith Mitchell; UKNOF Subject: Re: [uknof] Airflow management blanks On Tue Apr 28, 2015 at 03:01:38PM -0400, Martin Hannigan wrote: > On Tue, Apr 28, 2015 at 2:59 PM, Keith Mitchell wrote: > > > Opinion: Data centers should provide them. > > > > Do I feel an Open-IX Data Centre standard requirement coming on :-? > > Not a bad idea.

If you are buying retail racks, the data center provider _should_ provide them. You're renting. It's like renting an apartment without doors. If you buy wholesale and buy suites, maybe. The real problem is a green and cost efficiency issue. How many suites will buy blanks over and over and over for the life of the suite? Way too many. Opinion: Data centers should provide them.

Re: [uknof] Airflow management blanks
They are a stupid price, I agree. If you fancy a spot of DIY, you can create full rack blanks for around £7 each. Have a search for Correx Corrugated Plastic Fire Retardant. It is also known as Fluted Plastic. You can get it 2mm and 4mm thick and the 4mm is about strong enough to use in a rack, although to be fair in full sheets we used the 2mm stuff by popping a number of cage nuts/screws through it to pin it down. We put a couple of 1U metal blanks behind it to stop it bowing too much. It is a tad of a cheap and cheerful approach, but when you need to blank an entire new suite, it actually serves the purpose very well for the money, so long as you don't mind getting busy with a straight edge and knife.

Re: [uknof] Airflow management blanks
Interesting/useless side note: Telehouse just yesterday asked us if we wanted to take part in a trial whereby they would install these blanking panels in each of our unused U’s in an attempt to reduce the temperature in TFM17. Because the room is pretty small, I guess it gives them a chance to try it on a small number of customers. They did say that their intention was, if the trial was successful, they’d roll it out across the whole campus. Blanking plate salesmen, start your engines. — Charlie > On 28 Apr 2015, at 15:59, Mike Hughes wrote: > > Greetings UKNOF folks... > > I'm after some of those lightweight "corrugated cardboard" (can't think of > what else to call them) blanking sheets to put in racks to stop hot/cold > aisle "rebreathing". > > Want to give these a go, but keep coming up on metal blanking plates. > > Anyone got a manufacturer/supplier that you're able to share? > > Cheers > Mike
Re: [uknof] Airflow management blanks
Agree on the APC ones. We have large panels (power coated aluminium) for large sections (whole empty racks etc) and then a couple of thousand of the APC ones. Indeed the last two cases we bought after pressuring everyone we knew, eBuyer beat them all on price by a small amount. We've tried all the plastic board ones and suchlike and found you had to stick or tack them down to block any sensible level of airflow as they tended to sag and curl at the corners or on larger sheets of them.

Google "tear off blanking panels". I think the ones we have are PlenaFill. Rich.
Re: [uknof] Airflow management blanks
I suspect you're thinking of something like PlenaFill, they come in sheets that can be easily torn down to the appropriate number of U.
