resource types from OpenStack projects, but also provides a common type, so you can create basic resources and handle resource properties yourself. Indexers are also responsible for linking resources to metric metric. How to choose Back-ends, choosing back endGnocchi currently offers a centralized different storage engine: file,swift,s3,ceph (preferred). The driver for storage is based on an intermediate library called Carbonara, which processes time

CEO of RedHat on VMware, OpenStack, and CentOS RedHat has completed an acquisition to build an open-source stack that leads the hybrid data center, and its main competitor is VMware. The duel between RedHat and VMware remains to be observed, but Jim whitehust, CEO of RedHat, believes that open source will ultimately define the future of enterprise IT architecture. I met whitehirst and talked to him about the overall planning of cloud, open source, and RedHat companies. Next, let's take a look at

changes, which poses a great challenge to the design and implementation of the system;C. In addition, a large amount of metadata required for storage devices is also a non-negligible cost overhead;The above two schemes have the common thought: record and maintain the state of the data (that is, metadata), the data is addressed to the metadata server first query, and then access the actual data;3. No metadata design (mainly for ceph): different from t

In order to solve the interaction between the various business, the leaderboard system realizes the business resource quota and resource isolation scheme.

not the only choice. In Windows®In the system, ServerMessage Block [SMB] (also known as CIFS) is the most widely used option (like Linux supports SMB, Windows also supports NFS ). One of the latest distributed file systems, also supported in Linux, is Ceph. Ceph is designed as a fault-tolerant Distributed File System with UNIX-compatible Portable Operating System Interface (POSIX ). For more information ab
