So ACard has a battery-backed DDR2 RAM disk capable of taking 8x8GB RAM sticks in it.. and then offering them up using 1 or 2 SATA ports, so it's lucky if it even caps out @ 600 MB/s.
DDRdisk has a PCI-e device (but only PCI-e x1 I believe) that is 4 GB of RAM and 4 GB of SSD for holding the data, but charges like $1400.
So here's my question.
Is ANYONE aware of a device more akin to the ACard than the DDRdisk in that it takes 8 (or even better if it could take 16) DIMM's, with support for at LEAST 4 GB DDR2 DIMM's, but that is more like the DDRdisk or Fusion-IO in that it is connected via PCI-e (preferably x4, x8 or even x16)?
One that is like the ACard in that I don't have to pay $1400 (like the DDRdisk) for 4 1 GB DIMM's and a board? I want it EMPTY. I want DIMM slots *I* get to fill with RAM at the prices I buy it at.
I want a battery that'll keep it running for a couple of MINUTES. I don't need hours.
I'd LOVE it if it also had the feature some of these guys do, that if the power doesn't come back on it dumps the data to a CF card (or two) that's on the board, to reload it when the power comes back up, but that's optional.
Even better, since I'm basically buying a PCB, a good controller chip and a battery, how about it doesn't cost me more than a couple hundred bucks?
WHY DOES THIS NOT EXIST? WHY CAN I NOT HAVE 32, 64 or 128 GB of battery-backed DDR2 RAM offered to me via an x8 or x16 PCI-e card showing up as a simple block device on Linux like the Fusion-IO does?
Do you have any idea how many of these you could sell if I knew it existed?
ACard is doing it, but with friggin SATA connections, making it useless. DDRdisk is doing it right, but with SSD I don't need and charging me more than is even remotely conceivable to ever pay.
I mean heck every motherboard I own does this exact thing all day; RAM connected via fast bus to the processor.. heck, why doesn't Intel just throw in a battery slot on their server boards for the RAM?
Ok, I'm done ranting.
