Looks like another new DC for Melb coming soon...

What happens when their is over supply in Melb?

Who knows? Hasn't happened yet

Be interesting to see what happens when it does though

Brisbane De-Ja-Vu

No Space in BNE. Then:

Fujitsu / Half Full (06)
Pegasus DC1 Opens / Fills (06)
iSeek DC2 Opens / Fills (07)
Pipe DC3 Opens / Fills (07)
HostNetworks DC1 Opens / Half Fills (07)
Pegasus DC2 Opens / Fills (08)
Fujitsu / Full (08)
Pipe DC4 Opens / Almost Fills (08)
Brennan IT Opens / Empty (08) (80 Cabinets)
Digital Sense / Empty (08) (200 Cabinets)
iSeek DC3(In Production/Opens 09) 400 Cabinets


There are currently around 180 cabinets of space in Brisbane. Once Melbourne has the same space available it will have the same effect. This will not happen though for the next 18 months.

I think the company mentioned in the news real have already missed the boat.

Jon,

Fujitsu ain't full, committed maybe, but not full.

Also, I believe HostNetworks is now 100% committed now too.

Guess I should also throw in iseek's Woolloongabba facility. Released April 2006, sold out by Jan 07.

I'm with you though, there's a lot more demand for DC space than supply and ultimately if it hasn't been taken it's generally a pricepoint consideration.

Stu

OK - So who filled Fuji and HostNetworks....Hmmmmm Let me think about it

There is ALOT more then 200 Racks I was there today.

Stage one alone is 120 Racks

This is heading a bit OT but I guess it's worth noting that in the past 2 years there's been a huge change in heat dynamics within DCs. Just cause there's a huge number of racks available doesn't implicitly mean there's actually capacity.

I know at least one DC in Sydney which requires 8A per rack. That's 1 blade chassis & 4 860s.

Stu

8amps ? Did you mean 80amps ?
If so, 8amps is nothing ! I've got 40amps in my first rack, I'm hoping for a typo here.

Perhaps I should take a photo of the Air con Array for stage one ? You might be Gobsmacked. They deliver 2000Watts per square meter, I think they have capacity, Also they've sucked the local substation dry which had major work done too it about 2 years or so ago along with all the electricals they've deployed onsite.

40Amps?! Even in a facility with over the top power allowances why would you want to undoubtedly create the heat load you are seeing?

Assuming Stu is speaking of the DC I am thinking of (And are housed within) a basic rack will provide a 10A circuit, 8A being max average draw. Additional power is avaliable, but is costly and eventually gets to the point where you are required to purchase additional floorspace as so they can offset your usage.

Right-t-o.

Am I missing something here ?

You can't do a whole lot in a 42RU rack with the max average draw of 8amps

Most of the racks around me have 30amps if not 45amps I don't see the problem.
It's not like the air is going to konk out.

No, 8 amps. With 40 amps in a rack you would be pumping out some seriously warm air from the back of your rack. In a situation where there's 100+ racks only a small % of them would need to be up near this sort of amperage before it'd start affecting the average per rack current draw and subsequent kW of cooling required.

As a rough calc, 40 amps of standard Dell kit translates to ~8400 watts (~2.3 tons of cooling).

I doubt it. You say 2000W per square meter and a standard 800mm rack is ~1.7 square meters (although for what it's worth, I thought aircons dealt with cubic meters but hey, I'll just give you the benefit of the doubt).

Using your figure, 8400W translates to ~8.4 square meters. SO, either your DC is overselling their aircon, you haven't got the numbers right or your rack has taken the capacity of ~5 racks and now you're either gonna be forced to pay through the nose OR the DC will eventually get hotter and hotter as it gets to physical capacity. Either way, I'm sure am glad I ain't in any DC your in.

<stab> 2000W for an aircon is tiny. It translates to 2kW. iseek has 4 APC FM40's (with more coming online soon) in a relatively small DC, these are 40kW and produce about 12 tons of cooling capacity.</stab>

Optus Ultimo DC? And yeah, that EXACTLY what happens, sure, any DC can give you 40A but eventually what they start doing is simply pricing that extra 10A circuit at the same cost as the rack itself. In Ultimo's case, it's been pounded down to 8A cause they've got a bunch of 'greenfield' (ie. been there since it was built) government clients who have packed their 42RU with IBM HS20 blade chassis.

See, you're looking at it all wrong, it really has a LOT less to do with the RU nowadays and more to do with power and cooling. Blade technologies are STILL more efficient in both of those even if you can only get 1 in per rack.

As for your 30-45A scenario, your DC is either underpopulated, your spinning crap, it's a small (aka company DC) operation with lots of excessive not very efficient aircon OR (and this seems unlikely given the market at the moment) you're in a really high capacity DC paying top dollar.

That is EXACTLY what eventually happens. We've discussed this all before but I'll reiterate. Usually once a DC is at cooling capacity they either start jettisoning their cheapest or most abusive clients, add additional aircon (leading to the inefficient approach of your typical company 'server room') or put a whole bunch of heat extraction doors on the really hot kit.

All of these aren't long term solutions, they are very heavily short term and ultimately don't provide a whole lot more in additional DC power/cooling capacity (ie. they keep things at 'acceptable' levels not just suddenly mean you can add another 10RU).

Stu

Yeah whatever perlboy your assuming way to much here.
This D/c is nothing like anything else is AUS, I've posted about it in the Lounge bar. Perhaps you should read it if you haven't already.
I'll get photos of the cooling array and then you might just mellow out.

MIght go do this right now if I my camera has battery

-Welsh

Assuming what?

All I'm saying is that 30-45A current draw is NOT normally classed as acceptable power draw.

As for your post in Lounge Bar, that'd probably be this one:

Like I said though:

Which, if the press is correct seems like the exact caveat I'm apparently 'assuming'.
