SATA based SSDs are dead to me.

Recommended Posts

Let me introduce you all to something very special. The Sun F20.

 

What is an F20 you say? It's four of Sun's 24GB 'fmod' chips, attached to a PCIe 8x card, that also doubles as a SAS HBA. That's 96GB of PCIe connected flashinsanity.

Shiny.

 

Woo.

 

Anyway, because some of you are nerds, and are still reading here, lets run some zpool stats after striping the 24GB chips together.

Yes. That is write speed. In Megabytes per second. Baby SSDs can read. Real big boy ones can write...

Fuck me. I like.

 

 

I can see where Sun is going with this... and it can only be good!

Fuck me roman.

 

And the approximate cost?

Around 5k AUD retail per card.

 

Nobody said it was cheap technology.

Poor zebra.

 

Doesn't know the difference between USD and AUD...

 

http://shop.sun.com/is-bin/INTERSHOP.enfin...e_US-SunCatalog to buy one :P

 

For some actual specs: http://au.sun.com/products/disk/f20/

 

Oppps *_*.

 

Well then. More $.

 

I think the thing that keeps this kind of stuff a little bit technical-obscura is the fact that it's an unusual device for an unusual market. You won't see these in just any old server. Only really specific workloads, with really specific requirements. HPC, really high end databases, OLTP...and some of the kinds of stuff we do. Wonder when it will trickle down to the "make my games go faster" market, though?

Why not take it home and install windows xp (32 bit, cos it's more stable) on it, and put 8gb of ram in the system so your ram isn't a bottleneck.

 

 

Then play Unreal tournament on it.

Good fucking lord. They should give these out in Sun goodie bags.

Was reading an article about these a while ago, pretty awesome piece of tech. But I can't see them getting down to consumer/gamer level prices anytime soon. There are a lot of nice pieces in that end of the industry that would be a luxury to have in a home PC but it's all $$$

I won't hold my breath :)

 

There are some awesome storage solutions available at an enterprise level that will never make it to the mainstream. Though it's nice to drool :)

J4500 would be nice but a X4540 would fit more comfortably in my house. Dreaming.

So what will this puppy be used for?

 

Spoke with brains briefly about it last night, and he suggested it was going to be used for the metadata LUN.

Yeah, a PCIe based SSD is much more of interest to me than a 2.5" drive.

 

I'd be happy with moderate speeds(100MB/s each way) and it only using a single 1x PCIe slot.

 

Storage level of about 120gb would be fine, just for OS/installs.

 

 

 

Leaves other drive bays free for 'real' storage.
