Mirantis, one of the benchmark companies in the OpenStack field, released the latest MOS 8.0 version in early March 2016. This paper tries to make some inductive analysis based on the public data.1. Version Overview 1.1 overview Community version: Liberty, the default integrated components include ceilometer,Cinder,Glance,Heat,Horizon, Ironic (first support),Keystone,Murano (an application catalog, first-time support),Neutron (using Open vSwitch 2.3.1, enhanced L3 HA VRRP, support for IPAM,

Cinder-volume supports a variety of volume provider, we have been using the default LVM in the previous section, we will increase the NFS volume provider.Although NFS is more applied in experimental or small-scale cinder environments, it is unlikely to be used in production environments due to performance and lack of high availability, but the significance of learning NFS volume provider is:1. Understand how Cinder-volume supports multiple backend2. More importantly, you can understand how cinde

Container classificationFrom the point of view of business data, containers can be divided into two categories: stateless (stateless) containers and stateful (stateful) containers.Stateless means that the container does not need to save data while it is running, and the result of each access does not depend on the last access, such as a Web server that provides a static page.Stateful means that the container needs to save the data, and the data changes, and the results of the access depend on th

Because the yum source download on the openstack official website is slow, we now download the built-in installation packages of openstack, epel, CEpH, and RedHat, and create a local update and install Yum source. 1.

Google a bit, the popular open source Distributed File system has a lot of, introduced as follows: Mogilefs:key-value file system, does not support fuse, application access it requires APIs, mainly used in the Web area to deal with a large number of small pictures, the efficiency is much higher than the moosefs. Fastdfs: The Key-value file system, which is improved on the basis of mogilefs, also does not support fuse and provides better performance than mogilefs. Moosefs: Support fuse, relativel

VMWare Workstation Virtual Machine Access Extranet Usually in the use of virtual machines when there is no need to use the external network, the configuration of Ceph, the rapid installation of ceph need to use the outside network, suddenly found that the network, after learning on the Internet, finishing the content. With the NAT mode, I used to think this is a network exchange with the host, want to acces

Ceph to a logical hard disk, so that all nodes are accessing the same address, or you can access the same Web project through the NFS shared file service with Linux itself. Whichever way you use it, we guarantee that:1) access to the same Web project2) The cube storage address is consistentBecause the same Web project requires the storage address of cube to be consistent, it is required that the cube storage address must be the same.When used, the im

At a higher level, a cloud service management platform like MANAGEIQ provides some management methods for workload and policy control between different cloud service environments, and it is worth mentioning that these management methods incorporate business rules considerations rather than just technical implementation issues.We have witnessed the process of data and storage technology from analog to match to remix.
