Dynamic disk concept


A dynamic disk is a physical disk that is upgraded and managed by the Disk Manager. It does not use partitions or logical drivers, but only contains dynamic volumes created by the Disk Manager. Dynamic disks can be accessed by Windows 2000 operating system.

Basic disk concept
A basic disk contains primary partitions and extended partitions containing logical drivers that are used by Windows 2000 and Windows NT operating systems. Basic disks may also include volumes created by using Windows NT 4.0 or early versions, striped volumes, mirrored volumes, or RAID-5 volumes (also called striped volume with a parity check). As long as the file formats are compatible, basic disks can be accessed by Microsoft MS-DOS, Microsoft Windows 95, Microsoft Windows 98, or Windows NT operating system.

Concept of a dynamic domain name of OceanStor 9000
OceanStor 9000 dynamic domain name: A domain name that is resolved to return a dynamic front-end service IP address of a node

Concept of the number of mirrored disks
The number of mirrored disks can be understood as the total number of data copies (including source data).

Concept of a dynamic front-end service IP address of OceanStor 9000
Dynamic front-end service IP address: An IP address dynamically allocated to a node by the InfoEqualizer from the manually configured dynamic IP address pool. After a node fails, its dynamic IP address is automatically assigned to another node, and a client can access OceanStor 9000 through this dynamic IP address.

What is Beamforming
The beamforming or Transmit Beam Forming (TxBF) technology produces the strong directional radiation pattern based on the strong correlation of the spatial channel and wave interference principle, making the main lobe of the radiation pattern adaptive to point to the wave direction. This technology improves the SNR, system capacity, and coverage range. Beamforming or TxBF is an optional feature in the 802.11n standard. Beamforming includes explicit beamforming and implicit beamforming. Explicit beamforming requires the receive end to send information about the received signal to an AP. The AP then adjusts the transmit power to the optimal value according to the signal information. This function increases the SNR of the receive end and improves the receiving capability. Implicit beamforming allows an AP to automatically adjust the transmit power to increase the SNR of the receive end based on channel parameters without requiring the receive end to work with the AP. Currently, mainstream terminals do not support beamforming.
