IBM Flash Memory Breaks 1 Million IOPS Barrier

Posted by ScuttleMonkey on from the flash-in-a-flash dept.

alphadogg writes to tell us that IBM is claiming a victory on the flash storage front. Their new research project "Quicksilver" is claiming data transfer speeds of more than 1 million input/output operations per second (IOPS). "IBM said Quicksilver is two and a half times faster than its own SAN Volume Controller coupled with IBM's DS4700 storage. It would also be two and a half times faster than technology from Texas Memory Systems, which says it has the world's fastest storage with an IOPS rate of 400,000. "

    While managing to achieve 1M IOPS is somewhat impressive, it's not hard to do for an optimal theoretical situation.

That same system would only pull about 20K IOPS on the SPC-1 real world benchmark.

      IOPS are a normal measure for server hardware. It's the number of I/O operations per second the device can perform. Most server workloads, particularly database servers, require a lot of small I/O operations per second. With a single mechanical disk, it's pretty easy to work out the number. Pretend the time taken for each read is zero (it isn't, but it's really tiny so we can ignore it). Then take the reciprocal of the seek time. For a cheap disk, this is around 9ms. Google says the reciprocal of 9ms is 111Hz, so a 9ms seek time translates to 111 IOPS. Fast drives have average seek times down at around 4ms, which gives 250 IOPS. So, to put this in perspective, it's as many independent operations per second as 4,000 individual high-end disks, or almost 10,000 cheap ones.

      By the way, for a workload with a lot of independent reads or writes you'd be surprised how slow a hard disk is. With a 512byte block (common on hard drives) you get a maximum throughput of around 50KB/s for a random access pattern on a cheap drive, going up to around 125KB/s on an expensive one. Even very cheap flash can do better than this, so for moderate sized databases (a few GBs) with a very heavy access load flash works out a lot cheaper.

      Oh, and for reference each of the ops in this test was up to 640KB, giving a maximum of around 640GB/s data transfer.

      MB/s is only a measure that's meaningful for sequential reads where the data can be prefetched. Most enterprise storage is based on applications that read randomly all over the disk (like databases and email servers). The benchmark measurement for this type of application is in the number of operations you can do per second. A single hard drive spindle can do between 80 and 150 IO/s, which would generate the number of IO/s times the size of the IO blocks per second.

      How does this translate into normal transfer speed units like MB/s? Otherwise I have no point of reference to tell if I am impressed or indifferent.

      I'll try to help.

      MB/s is a measure of IO throughput. Often this isn't the most relevant figure for 'enterprise' storage. Certain applications do a lot of random access IO so IOPS becomes more important than throughput.

      Today a typical desktop disk is capable of about 100-150 IOPS. That's a rule of thumb range that varies based on operation size, cache, etc. It works pretty well usually. You can aggregate disks and get almost linear scaling; 12 disks, for instance in a device like this, will give you a maximum of 1200 IOPs, roughly. A common USB Flash device can break 1000 IOPS with certain access patterns.

      The second graph on this page illustrates the extreme IOPS advantage of Flash for certain applications. Disks are limited by head actuation and rotation latency. This is why enterprise storage vendors have been pursuing Flash aggressively. That's what this story is all about.

      The dream is to host the same IOPS in with an order of magnitude less physical space, power, heat, etc. If you don't need thousands of IOPS (and most PC users don't) then it isn't very interesting. If you happen to run an OLTP system with thousands of reads/write per second it means a great deal.
