RAID
A circuit board that connects devices in parallel with each
other. It provides connectors for slots to support power
distribution, management, and auxiliary signal connection.
The slot ports are connected by high-speed twisted pairs.
Basic input/output system
Hard disk drive
In a running system, inserting or removing a board does
not affect normal running of the system.
Input/output operations per second (IOPS) refers to the
maximum number of I/O operations the system can
perform per second, which is the most important
performance measurement to characterize the storage
system.
Short for PCI Express. It is a new bus standard adopting
peer-to-peer and bidirectional interconnection technology
to replace PCI and AGP interface specifications. It supports
serial data transmission rather than parallel data
transmission of PCI or AGP. With PCIe, the data transmission
speed between devices can be improved greatly.
A technology that combines multiple independent hard
disks (physical hard disks) in different ways to form a group
of hard disks (logical hard disks), thus providing higher
storage performance than a single hard disk and providing
