openstack block storage

10. OpenStack Object Storage Service (SWIFT) configuration: I added two hard drives (SDB,SDC) to the compute node for storage, and the compute node in my build is the storage node, because the computer can't pull more virtual ... Brief introduction: There are four main components of Swift: Swift-proxy-server, Swift-

We are building a swift environment on our own these days. After reading some documents and combining my own practices, I wrote it down: 1.

high. Thermal migration (hot or live migration)-thermal migration is also called dynamic migration. The virtual machine still works during the migration, and the user can continue to use the virtual machine. This is the type of migration that is described in this article. Thermal migration is divided into the following two types: (1): The virtual machine data exists on the shared disk (GKFX storage-based Live Migration), as shown i

Recently, a student asked me about the difference between the hadoop Distributed File System and openstack Object Storage Service, and said a few words to him. I personally think that data processing and storage are preferred. There is no absolute quality. It should be used based on specific applications. I found some online saying: this is the original: http://

Recently built a swift cloud storage architecture for the needs of the jobLet's take a look at the technical knowledge Inside: The SWIFT Service is a component service belonging to OpenStack, the Component Services in OpenStack are Keystone, Nova, glance, etc., different services are responsible for different functions, we build today swift+ Keystone,swift is res

Recently, someone mentioned a problem in Quora about the differences between the hadoop Distributed File System and openstack object storage. The original question is as follows: "Both HDFS (hadoop Distributed File System) and openstack Object Storage seem to share a similar objective: To achieve redundant, fast,

) Client Authentication is provided by the get method of the rest interface and is usedV1.0As the path. In addition, there are two headers that must provide:X-auth-userAndX-auth-KeyAnd their values are the user name and API access key respectively. Each rest request accessing the openstack Object Storage System must contain a specific header in the HTTP header:X-auth-tokenThe value of this header is the
