similar to: The I/O bandwidth controller: dm-ioband Performance Report

Hello all, I've implemented a block device which throttles block I/O bandwidth, which I called dm-ioband, and been trying to throttle I/O bandwidth on KVM environment. But unfortunately it doesn't work well, the number of issued I/Os is not according to the bandwidth setting. On the other hand, I got the good result when accessing directly to the local disk on the local machine. I'm

Hi All, This is the dm-ioband version 1.12.0 release. dm-ioband is an I/O bandwidth controller implemented as a device-mapper driver and can control bandwidth on per partition, per user, per process , per virtual machine (such as KVM or Xen) basis. The major change of this release is that a new bandwidth control policy "range-bw" is supported. This policy is developed by Dong-Jae Kang,

Hi Alasdair, This is dm-ioband v1.12.3 release that is a minor update to avoid sparse warnings other than related to the event tracing. (I used sparse-2009-07-29.) This patch can be applied to the current dm-devel tree and 2.6.31-rc4, so could you please replace dm-add-ioband.patch in your tree with this? And I would appreciate it if you would let me know your thoughts about merging dm-ioband to

Hi Alasdair, This is dm-ioband v1.12.2 release that is a minor update to fit the current dm-devel tree. Could you please replace dm-add-ioband.patch in your tree with this patch? And I would appreciate it if you would let me know your thoughts about merging dm-ioband to upstream.

Hi Alasdair and all, This is the dm-ioband version 1.10.5 release. This patch can be applied cleanly to current agk's tree. The only change from the previous version is that some blktrace messages are added by Alan D. Brunelle, thanks Alan. Alasdair, Could you please tell me your opinion about merging dm-ioband to upstream? What else do I have to do? Is there any possibility that dm-ioband

Hi everyone, This is a new release of dm-ioband and bio-cgroup. With this release, the overhead of bio-cgroup is significantly reduced and the accuracy of block I/O tracking is much improved. These patches are for 2.6.28-rc2-mm1. Enjoy it! dm-ioband ========= Dm-ioband is an I/O bandwidth controller implemented as a device-mapper driver, which gives specified bandwidth to each job running on
