.. that various vendors have been trying to sell to everyone for the past 4 or 5 years.
Too hot in fact. Most datacentres have moved to charging strictly for power (and cooling that is related to the power charge) instead of square footage of space or bandwidth.
Now they are moving to say they’d rather not have a pile of blade servers in their colos anyways…
I know that even without going to blade servers, the place I work for has basically run the colo space at a Tier 1 datacentre out of power. They have square footage they can’t utilize because we’ve had gobs of extra power rerouted to our cage to power the tightly packed power hungry 1U servers we have jammed in there as it is.
Going to blades would only make it worse.
How? Read on.
This was posted as part of a comment on an article about an IBM mainframe consolidation project :
Every day another vendor tells us that blades are the solution to all our problems, so long as those problems are how to get the air to plasma temperatures in our data centres.
Of course this power density is our excuse to buy the next ‘green’ solution and deliver in rack water cooling because that is the only way to stop the blades frying.
Best not forget the few million for that really expensive box for your disks to live in either, or the floor reinforcements to hold it all up.
Kinda says it all, when it comes to blade servers, eh?
