Ndm id11/12/2023 This change must be done in the openebs-operator.yaml file that you have downloaded before OpenEBS installation. This configuration must be added in openebs-ndm-config under Configmap in openebs-operator.yaml. Add the blockdevice path in the following configuration for specifying particular disks. For including the selected blockdevices, update the operator YAML file with the required blockdevices under NDM configuration section so that only these blockdevice will be taken for the creation of blockdevice CR. Users can include only selected block device for the creation of blockdevice CR and then use only the created blockdevice CR for cStor pool creation or using for provisioning Local PV based on device. Admin operations #Ĭreate blockdevice CRs for unsupported disks Admin Operations # NDM offers pre- and post-processing features.This section provides the operations need to performed by the Admin for configuring NDM. The checkpoint restart feature is offered in NDM.įTP does not allow for checkpoint restart. NDM compresses data and therefore uses a low bandwidth.įTP does not compress data and uses a higher bandwidth. NDM is an asset when dealing with large data packets through its fully automated feature.įTP requires thorough follow-up of the processes for file transfers and downloads.ĭata security is guaranteed with NDM which offers encryption.įTP has the encryption option desired for improved data security. NDM offers for logging, audit, and control features.įTP does not have elaborate processes for logging and auditing. This is a great help, especially with regards to logging of all file transfers which makes auditing quite easy. Further, it offers integration and added management tools which allows for the automation of different aspects of the client production environment. The feature is important as a comparative scrutiny between the two shows that less bandwidth is utilized by NDM as opposed to FTP and thus NDM may be faster.Īnother important feature of NDM over FTP is that it offers a checkpoint restart, a feature not available in FTP. NDM is a step ahead because when uploading or downloading data to the server, it employs a unique compression feature. This is not a feature that is ordinarily available in FTP.Īlthough comparing performance, you might find NDM and FTP to offer more or less the same services. If the data being transferred is highly sensitive, NDM allows for encryption of the data being sent to ensure data integrity. This is a good welcome for those who prefer the traditional method of entering data from a client end and uploading it up to the server. Automation of exchange of data makes work quite easier as opposed to an FTP file transfer. An example is financial companies that are constantly working on collecting data. The main use of NDM is to help in the automation of the file exchange between the client and the server.ĭue to its automated feature, NDM is a great resource to use when dealing with large data packets. Ownership of the company has changed through time to Sterling Commerce, and the new name used in reference to NMD is CONNECT: Direct. “NDM,” on the other hand, refers to network data mover, a name that has stuck since its inception. To place files, this process is known as uploading. In the event that the client is granted entry, they can get files from the server which is commonly referred to as downloading. Upon request from the client to server, the server has been programmed to either allow or disallow the client access. The technology behind the use of FTP is that one of the ends of the exchange ought to act as a client while the other end must act as the server. “FTP” is an acronym that stands for “file transfer protocol.” This protocol is by default the standard mode of exchanging information between two computers, mainly the user and the server. One of these is the FTP and the other NDM. There are two main exchange protocols that can be used. There is a need to check on an acceptable protocol to use to allow for a seamless exchange. In most cases, information will be seen from one computer which is the user, and the other computer receiving the information which becomes the client. There are several ways that the exchange of files between two computers can be done.
