Seeing a lot of clients and bigco's turning their back on blades now, going back to rackmounts. lack of flexibility in i/o slots and cpu sockets.

Get yourself a small stack of rackmount jobbies

P770 or P790, back of the net!

Great for business but not much fun for a tinkerer.

You'd be surprised what you can do with an i these days. All you need for database and web apps on one box, and you don't need to spend £18000 either...

AS400 and whatever it's called now, IBM i I think, is/was/may well be the canines gonads, set it and forget it, a real working black box, I know very little about it except what I just said.

Stop mucking about with blades, get something decent...

I'm just 'helping' a guy online who's bought two JS20's on Ebay, hoping to put RHEL on them or AIX if he can't. I've asked if he has the the Blade chassis, management module(s), etc, gone very quiet.....

BladeCenter load balances across them and since PSUs are more efficient under heavier loads it does save a bit.

Surely load balancing means lower average load per PSU and thus lower efficiency? Perhaps they just want to avoid running single PSU at top level which might not be as efficient as some mid point.

Inactive power supplies should not use much power because not a lot should be drawn through them.

You can save power by pulling half the power supplies and running it in non-redundant mode

I had the dubious title of "BladeCenter Champion" when IBM launched it. The BC-H is a bit of a power monster. You can save power by pulling half the power supplies and running it in non-redundant mode but the fans go to 100% and anyone within a couple of miles thinks Concorde is back. You should also advise ladies in skirts to beware standing directly behind when that happens.

Blades is a nice idea

Just don't bring one to a gunfight.

Yup - three phase! Does that three times more leccy - I've no idea!?

You might get old bill knocking on yer door to check how many plants you have in your house.

They were three phase commando sockets with leads as thick as your thumb. I had some e4500's (5) for a while but the village kept blowing transformers and i looked at my electric bill

I would like a look at one of these arm super computers that dell took over. They look fairly clever...

Aye - blades also not saving much money and much harder to resell, plus they are not suitable for large IO scenarios where lots of disks are necessary.

Now if 64-bit ARM blades that use a LOT less power could become interesting, but that's a few years away...

Aye but disk would be from SAN but then again - i've no idea what the IO is like on Blades, is there fibre, NPIV?

The ones we have are 64-bit POWER6/7 and I hear POWER7 is quite 'green' but I suspect that's marketing bollocks...
