Inband management concept


The management control data of the storage device is transferred on the same link as the service data. In a typical connection, the application server connects to the storage device by using the service network port. Install the Inband Agent software (part of the HostAgent software package) on the application server to manage the storage device without interrupting service data transfer.

Difference between the inband management and out-of-band management
The differences of these two management modes lie in: Reliability: In out-of-band mode, when the service link is faulty, you can still log in to and manage the storage device by using the management link. Management mode: In out-of-band mode, either the ISM or CLI can be used for management. In inband mode, only the ISM can be used. Networking: In inband mode, management data and service data share the same link. Therefore, the number of network cables is reduced. Functions: In inband mode, the application server collaborates with the storage device. In some cases, the performance of the storage device is enhanced.

Out-of-band management concept
The management control data of a storage device is transferred on a different link from the service data. In a typical connection, the maintenance terminal connects to the management network port or serial port of the storage device to manage the device, and the application server connects to the service network port of the storage device to transmit service data. The two links are independent of each other. The management mode described in the Product Documentation and Configuration Guide is the out-of-band mode.

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.

What is MRC
The maximal ratio combining (MRC) technology improves the signal quality of the receive end. In MRC, the same signal from the transmit end is received by the receive end through multiple paths (multiple antennas) because the receive end receives this signal using multiple antennas. Generally, among multiple paths, there is one path providing better signal quality than the other paths. The receive end uses a certain algorithm to allocate different weights to receiving paths. For example, the receive end allocates the highest weight to the receiving path providing the best signal quality, which improves the signal quality of the receive end. When none of multiple receiving paths can provide better signal quality, the MRC technology can ensure better receive signals.

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.
