I wonder that bottleneck in write and read data on Hard disk. Example, 10 VMs concurrent access hard disk and maybe bottleneck. How did OpenStack solve it? I hear about ring in Swift, but I not really understand. Please help me, thanks
you can use information below: https://swiftstack.com/blog/2012/11/21/how-the-ring-works-in-openstack-swift/ (https://swiftstack.com/blog/2012/11/2...)
I/O performance has to be addressed by external storage, appropriate I/O spreading across the disks spindles (Raid1,5,6 etc...) and with integration of cinder.
Swift is object store that designed for application data purposes.
In one of the projects we used Cinder+Storage plugin.
Good luck!
