The power of a SAN in the palm of your hand!
> Less than 50 μs latency
> Over 120,000 random IOPS > Sustain 600MB/s random writes The world of storage is no longer just about capacity, it's now also about the need for extremely fast and reliable access to data. The ever increasing demand on today's servers combined with the exponential growth of processor performance, has exposed the limitations of today's aging storage architectures.The time has come for a truly innovative solution that takes enterprise data availability, scalability and access rates to a new level of simplicity and performance, without sacrifices.
Designed around a revolutionary silicon-based storage architecture known as ioMemory, the ioDrive is the world’s most advanced NAND clustering technology with performance comparable to DRAM and storage capacity on par with today's hard disks - giving you the power to improve both memory capacity and storage performance a thousand fold. The ioDrive unleashes such a dramatic performance increase that every server can easily contain the I/O performance of the world's fastest enterprise SAN. With sustained, random access rates hundreds of times faster than the industry’s fastest storage devices, it's no question the ioDrive is the industry leader in data acceleration technology. With 1000x the I/O performance, while only using 1% of the power required by any of today's other high performance storage solutions, the ioDrive in a league of it's own. The ioDrive unlocks a world of possibilities for I/O bound servers and the applications that drive them, ultimately giving end users the power to innovate the next generation data centers.
“Seldom have I seen technology advances that win in almost every way at the same time, in terms of speed, capacity, reliability, endurance, power usage and simplicity,” Steve Wozniak co-founder of Apple Inc. and the engineer who launched the home computer revolution.

Doesn't NAND flash have a write limit? How does that effect the lifetime of the ioDrive™?
NAND flash has a limit on the number of writes that can be done to an individual cell. The particular limit depends on the type of flash used. For Single Level Cell (SLC) NAND, the limit exceeds 100,000 writes to a cell, whereas for Multi Level Cell (MLC) NAND, it is on the order of 10,000 writes. Hence, in order to exceed the limit of a single 80GB ioDrive™, you would have to write almost 80PB (Petabytes) of data. Streaming data at 800MB/s to the card, it would take you 3.4 years of writing data non-stop to exceed the SLC limit. How does the data reliability of the ioDrive™ compare to a traditional hard drive? The ioDrive is far more reliable than a hard drive as it relates to data reliability. In both hard drives and ioDrives, Error Correcting Codes (ECC) are used to ensure that any minor failure doesn't cause data loss. Fusion-io uses strong ECC algorithms to ensure the safety of your data. Is the ioDrive prone to catastrophic failures similar to a hard drive? Most catastrophic failures in hard drives are the result of mechanical failures, causing total data loss. Because the ioDrive has no moving parts, it isn’t subject to the same mechanical failures of traditional hard drives. When a NAND chip on an ioDrive™ begins to fail, the data is simply written to an adjacent NAND chip. The result is zero data loss with only slight reduction in overall ioDrive storage capacity. Furthermore, the ioDrive’s RAID capabilities protects from controller or other major (but extremely rare) types of failures. Is it possible to RAID multiple ioDrives™? To the host operating system an ioDrive appears as a normal hard drive, so users are able to leverage any software RAID solution that uses the host Operating System’s native drivers. The Operating Systems volume manager performs the RAID function. How does an ioDrive’s RAID functionality compare to a traditional disk-based RAID solution? The ioDrive significantly outperforms the highest performance hardware-based RAID controller on the market. Can you truly replace RAID disk applications requiring high rate IOPS and life time in the 250,000 hr range? An ioDrive has a product life in excess of 250,000 hr - even when performing continuous writing to the NAND chips. Moreover, users can expect to achieve performance in excess of 100,000 IOPS by aggregating multiple ioDrives in a RAID configuration. Hence, an ioDrive-based system is quite superior to a RAID disk array. Does the ioDrive require a RAID controller?
The ioDrive does NOT need a RAID controller as it is directly connected to the system PCIe bus. Multiple ioDrives can be configured using the host Operating System’s logical volume management to do RAID 0,1,5 etc between ioDrives. Such an implementation is MUCH faster than using hardware-level RAID controllers. What is the latency of the ioDrive?
Small packet reads take approximately 50us. On writes the Operating System level write buffers are freed in just a few tens of microseconds once the data has been transferred into the NAND registers (buffer). It takes approximately 200-300 microseconds for the data to be imprinted in the NAND chip by a flush/sync directive or once the page is filled with write data. Does the ioDrive require a back-up power supply to protect from power outages? The ioDrive uses non-volatile NAND flash as its storage medium. Hence, when data is stored in the NAND chip, it is guaranteed persistent. Can the ioDrive be partitioned like that of a hard drive? Yes, users can partition the ioDrive. This is done in the same way as any other block device; by writing a partition table into the raw block device (using fdisk). Then users can use the partitions how they please - including as storage cache. Is the ioDrive affected by fragmentation like a hard drive? Users don’t need to worry about fragmentation with the ioDrive. A file can be scattered randomly across an ioDrive and it will still achieve full performance – this benefit is due to the ioDrive not having to seek a mechanical read head. Is Fusion-io planning to develop a ruggedized version of the ioDrive for extreme operating conditions? As a small company, Fusion-io has focused primarily on the enterprise storage market. We are regularly evaluating alternative form-factors and usage scenarios and pursue opportunities that we believe provide a strong value-add to end-users. Does the ioDrive support Full Disk encryption?
The hardware has the capability to do hardware accelerated full media encryption (AES 256). The initial
release of the product will not have that enabled, but we anticipate that an in-field firmware upgrade will be possible at a future date. The time frame will be determined based on demand. What methods are available for accessing the ioDrive? The only method for accessing the ioDrive is by block device. The ioDrive looks just like a hard drive to your OS. You can access the drive directly, format it with a file system, or even set it up as a swap space. Does ioDrive work with my motherboard As Fusion-io cannot test every motherboard the following guidelines should be used. Any quality motherboard that has a PCI-Express x4 or wider slot should work at full performance. Any 4x physical slots with only one lane will work if slot is properly built to spec. Does ioDrive work with different PCI-E slot widths? The ioDrive currently uses x4 signaling and x4 physical connector. It can be plugged into wider slots such as x8 and x16. The ioDrive will also work in x4 physical x1 signaling slots but with degraded performance. We cannot guarantee that using a x4 (or larger) physical to x1 physical adapter will work unless they are PCI-E SIG compliant. Will the ioDrive work with an external PCI-Express connector box/express card connector box? The Magma Express box is known to work properly with both the PCI adapter as well as the Express card adapter. The Express Card adapter achieves 1x performance rather than the 4x performance achieved when the card is installed natively. |
