In relation to the active network port, the standby network port is a
redundant network port on an AS. When the active network port fails,
the standby network port is activated to work.
conversion, RAID, LUN mapping, disk-striping setting, and other
service and fault alarm. It consists of the controller board and port
module.
An integrated system. It consists of the following parts: controller,
storage array, host bus adaptor, physical connection between storage
devices, and all control software.
A transmission mode in which data is consumed (read, listened to, or
watched) while it is being sent.
The process of dividing the consecutive data into the same-sized data
blocks and writing the data on each block into different disks. This
technology provides a faster read/write speed than a single disk can
provide.
The number of blocks in a strip in a disk array which uses striped data
mapping. Also, the number of consecutively addressed virtual disk
blocks mapped to consecutively addressed blocks on a single member
extent of a disk array.
The physical extent block that consists of strips in each physical extent
of a redundancy group.
To verify whether the check data block in a redundancy group strip
protects the protected space in the strip.
The technology used by the IP protocol to determine where network
segment packets are destined for. The subnet mask is in binary format.
Stored in a client, server, or router. The subnet mask matches the IP
address.
A mechanism of the computer system to achieve connections between
devices. It is characterized by the signal transmission between two
devices on the bus. One device sends commands and data and the other
device receives commands and data. Only one transmission can be
operated on the bus at any time. Transmission requests of each device
are ranked according to their priorities.
A system component that can receive SCSI I/O operation commands.
The logical layout where computer systems and network components
are interconnected with one another. The topological structure gives the
interconnection relationship among the components from the viewpoint
of communication, but the topological structure does not specify the
exact locations of components and the interconnection mode.
