1 billion 64-byte IOPS = 64GB/sec
DDR3-1333 DRAM = 10.6GB/sec

#13Steve Wozniak is a true hacker. Kudos for the achievement.
Is there any evidence that Woz did anything here?
He's their Chief Scientist.

#141 billion 64-byte IOPS = 64GB/sec DDR3-1333 DRAM = 10.6GB/sec I'll have the grain of salt, please.
They used a cluster of servers.

From the presentation:
"128 memory modules, in eight different servers, running an aggregate of a billion IOPS, 64byte cache accesses."
So "only" 7.5GB/sec (125,000,000 * 64 / 1024^3), or about 60Gbit/s per server, with 16 modules per server. Still fairly respectable by storage standards, at about ten times the theoretical max for SATA III of 6Gbit/s.

#16Does anyone know what this improvement actually is? The article makes it sound like their card is doing DMA to pinned user allocations, but that doesn't sound too revolutionary. I know next to nothing about storage controllers, but see the last many years of high-speed networking for an entire ecosystem based around that concept.
OS bypass hasn't really been done for storage, so that's new in some sense.
It has been done since forever.

#18That's 1 billion IOPS across 8 servers, each having 8 FusionIO cards.. So it's 15,625,000 IOPS.
Compared to an SSD that does 100,000 IOPS.
Each card seems to be a dual unit, not taking this into account as some SSD pci cards are also like this.

#19So it apparently makes their custom flash storage behave like RAM, and provides an API to OS and software developers to make use of it as such, but it's non-volatile, so everything persists in the case of power failure or reboot. Here's an informative quote from Wozniak from the press release: " Instead of treating flash like storage, where data passes through all of the OS kernel subsystems that were built and optim…
I'd say bandwidth is the main barrier for most computing nowadays, followed closely by storage

#20We have immensely powerful systems today, but it would seem the levels of abstraction and libraries add overhead (just how much? I don't know). I wonder how things like BareMetal (http://www.returninfinity.com/baremetal.html) would shake things up? Strip away those layers, and get back to damn near bare metal. Seems to be the magic here: they skipped all the abstraction, and are allowing direct access to the storage (I have to imagine, it's massively parallel as well).
