  • linked clone

    A technology that allows VMs to be made from a snapshot of the parent.

  • linked clone VM

    A duplicate of a VM that uses the same base disk as the parent VM and a chain of delta disks to keep track of the differences between the original and the cloned. The linked clone technology reduces the need for disk space and increases the maintenance efficiency. Linked clones apply to scenarios in which the VMs use the same software, for example, call centers. The differences between the parent VM and the linked clones are stored on the delta disks for the linked clones.

  • live migration

    A method of migrating VMs without interrupting services.

  • LLA

    See Local Log Agent.

  • LMA

    See Local Monitor Agent.

  • Local Log Agent

    A component that collects log information from the local node.

  • Local Monitor Agent

    A component that is deployed on a physical node and monitors data of various processes on the node.

  • Log

    A type of file that records the system events that occur while the system is operating. The system events include the operation, input/output (I/O) operations, exceptions, and security events. Engineers use logs to query information and perform maintenance on the system.

  • log node

    A node that records system operation logs.

  • logical unit number

    A unique identifier of a LUN device. A RAID group can be divided into multiple LUNs. Each LUN contains one or more physical disks.

  • LUN

    See logical unit number.

  • management module

    The management module of a server.

  • Media Access Control

    A protocol at the media access control sublayer and the lower part of the data link layer in the OSI model that is responsible for controlling and connecting the physical media at the physical layer. When transmitting data, the MAC protocol checks whether the data can be transmitted. If it can, certain control information is added to the data, and then the data is transmitted in a specific format to the physical layer. Upon receiving the data, the MAC protocol checks whether the control information is correct and the data was transmitted correctly. If both of these are true, the control information is removed from the data, which is then transmitted to the logical link control (LLC) layer.

  • MM

    See management module.

  • Network Computer

    A device that provides virtual desktop service.

  • network file server

    A distributed file system that allows remote file storage and access to the existing server through the NFS protocol.

  • Network File System

    A method of executing file sharing between UNIX systems. Through the NFS and the network, applications on the client can save data to and obtain data from the disk of a server. The NFS was first developed by Sun in 1984, and designed to facilitate sharing materials between PCs and operating systems through networks.

  • network interface card

    A device that is identified as pethN in the virtual system, where N indicates a certain digit.

  • Network Resource Manager

    A node for managing and allocating network resources.

  • Network Time Protocol

    An application-layer protocol which uses IP and UDP to synchronize the time between the distributed time server and the client. NTP is evolved from Time Protocol and ICMP Timestamp Message and features high protocol accuracy and good health.

  • NFS

    See Network File Server.

  • NFS

    See Network File System.

  • NIC

    See network interface card.

  • NP

    network processor

  • NRM

    See Network Resource Manager.

  • NTP

    See Network Time Protocol.

  • operation and maintenance

    The operations and maintenance performed on the system by maintenance engineers.
