Telemetry Service  in openstack

Posted January 18, 2016 by Jossy Watson

Telemetry Service  in openstack Telemetry service is used in openstack for metering rate of resources used by each service and generating bills for corresponding usage. We can interact openstack via API or from command line. In the initial stage openstack development gave less importance to telemetry service. After development of heat service the telemetry service transforms into a Giant CPU Eater and also difficulty in time series data storage which leads to evolution. Now, many developers are working on telemetry project and the project was divided into three, Aodh,Ceilometer and…

CINDER : Block storage as a service

Posted by bipin

What is meant by a block storage? In block level storage each block acts as an individual hard drive and is configured by the storage administrator. These blocks are controlled by the server-based operating system, and are generally accessed by Fibre Channel (FC), Fibre Channel over Ethernet (FCoE) or iSCSI protocols. Since the volumes are treated as individual hard disks, block storage works well for storing a variety of applications such as file systems and databases. They also tend to be more flexible and provide better performance. But…

A comparative review of Swift vs Ceph

Posted January 6, 2016 by John Mathew

Swift and Ceph are popular cloud storage systems. Swift provides object storage and ceph provides object and block storage. Swift is an open source object storage system, that runs on standard server hardware. Swift supports RESTful HTTP APIs, data replication across various failure zones, scaling out without downtime etc. Objects are written to multiple drives, and data is replicated across a cluster. If a node fails swift replicates the contents from active nodes to new nodes in the cluster. Swift storage can be accessed through REST HTTP APIs.…

In other words, DAS isn't part of a storage network. The most familiar example of DAS is the internal hard drive in a laptop or desktop PC. In practice, the phrase direct attached storage is used most often in reference to dedicated storage arrays attached directly to servers. It is used to distinguish DAS from networked storage arrangements, like SAN…
