symbolset's Journal: Is the FC SAN dead?

Was it really only nine months ago that Fusion-IO launched their IODrive(pdf)? Since then they've gotten VC funding and made strides in new product (pdf).

For those who aren't following along, they make an Flash memory data storage product that looks like a 320 GB drive, but rather than connecting through legacy SATA interface it connects through the much faster PCI Express (PCIe) interface. By using RAID techniques to "stripe" the data across multiple flash chips, an abstraction layer to hide failed memory cells and intelligent logic to provide wear levelling they take fallible flash chips and turn them into reliable static storage that has performance characteristics more familiar in RAM. Their first version pulled in over $10K for a 320GB card.

They weren't the first out the door with this technology, and they weren't the last. Now OCZ has stepped up with a PCIe flash storage device that offers up to 1TB of storage in one PCIe slot and delivers it at a claimed 500GB/s. Now PhotoFast has one that does the same at 1GB/s for under $5k. That's not 1Gb/s. It's really one billion bytes per second.

Combine this with the new Nehalem technology available in platforms like the HP DL370 G6 with NINE PCIe G2 slots. Add free SAN software with HA clustering, unlimited snapshots, unlimited storage and other popular features like openfiler. Mix in a little Infiniband QDR.

Now you can have for under $60k a box that delivers 6TB of storage that does >1 million IOPS and can deliver that at about 96Gbit/s, in 4U. For another $5k you can get a MDS 600 5U to attach to that box that holds 75 of these 1.5TB 3.5" drives. Add 75 of this Drive sled and you've got over 100TB of slower storage at 3Gbps for an upgrade cost of under $20K. Even with 24/7 unlimited systems enterprise level support for five years you're looking at less than $100K. And it scales to infinity.

So here we are, with 6TB of insanely fast storage and 100TB of nearline storage, HA, thin provisioning, iSCSI and remote admin delivered at insane bandwidth. In 9U, for under $100k and burning less than 1000W, with unlimited LTU and unlimited support converged with current network architecture. And the speed and performance of the flash devices is more than doubling every nine months at the same time as the price goes down by more than half.

8Gbps FC San just got here. There isn't even a FCoE standard approved yet and when it is, it's not as fast as this by an order of magnitude.

Is the classic FC SAN dead?
