Fusion-io Leverages NAND as DRAM Extension

[Guest]

Fusion-io has developed a subsystem technology called Extended memory, which enables developers to take advantage of NAND Flash memory as an extension of DRAM.

“Since Fusion ioMemory has moved beyond legacy disk-era protocols, we can integrate new features like the Extended Memory subsystem to truly advance application performance for enterprise computing in ways that are simply not possible with traditional SSDs.”

In other words, this is simply an SSD format that can't hold data like a normal SSD.
It will flush the data every time that you turn off or reboot your system, just like RAM does.

Ha. I thought this was about AMD getting into the storage business...

How quickly will it wear out?

 

[JocPro]

Extended memory existed since DOS... Himem.sys anyone?

And this is different from a swapfile on an SSD how?

data set is kept in-memory all the time as NAND is a much more cost-effective memory solution

LOL

4x16 64GB DDR3 server memory $690 x80 (to make 5.12 TB) = $55,200

I'd give it about a year in a server environment.

WOW they've reinvented PAGING! Imagine that, you put the seldom referenced pages on AUX, keep the heavy used pages in DRAM. Shocking 1960s technology. Bet they get a patent on it.

The 320 sticks of RAM would take up a lot of space. Plus, you would need some device to plug them into. The small form factor, and the fact that it's a complete solution more than make up for the double cost.

In the fact that you only need to call allocmem in your program and decide witch tids and bits will be accelerated instead just bulking.
Pretty useful in mission critical or high volume server environments.
