(or overlapped) across multiple hard drives, but offers no fault-tolerance. RAID
level 1 is known as mirroring, which stores the data within at least two hard
drives, but does not stripe. RAID level 1 also allows for faster access time and
fault-tolerance, since either hard drive can be read at the same time. RAID level
0+1 is both striping and mirroring, providing fault-tolerance, striping, and faster
access all at the same time.
RAIDIOS: RAID I/O Steering (Intel)
RAM (Random Access Memory): technically refers to a type of memory where
any byte can be accessed without touching the adjacent data and is often
referred to the system’s main memory. This memory is available to any program
running on the computer.
ROM (Read-Only Memory): a storage chip which contains the BIOS; the basic
instructions required to boot the computer and start up the operating system.
SDRAM (Synchronous Dynamic RAM): called as such because it can keep
two sets of memory addresses open simultaneously. By transferring data
alternately from one set of addresses and then the other, SDRAM cuts down on
the delays associated with non-synchronous RAM, which must close one
address bank before opening the next.
Serial port: called as such because it transmits the eight bits of a byte of data
along one wire, and receives data on another single wire (that is, the data is
transmitted in serial form, one bit after another).
SCSI Interrupt Steering Logic (SISL): Architecture that allows a RAID
controller, such as AcceleRAID 150, 200 or 250, to implement RAID on a
system board-embedded SCSI bus or a set of SCSI busses. SISL: SCSI
Interrupt Steering Logic ( LSI ) (only on LSI SCSI boards)
Sleep/Suspend mode: in this mode, all devices except the CPU shut down.
SDRAM (Static RAM):
unlike DRAM, this type of RAM does not need to be
refreshed in order to prevent data loss. Thus, it is faster and more expensive.
SLI (Scalable Link Interface) : NVIDIA SLI technology links two graphics cards
together to provide scalability and increased performance. NVIDIA SLI takes
advantage of the increased
bandwidth of the PCI Express bus architecture, and
features hardware and software innovations within NVIDIA GPUs (graphics
processing units) and NVIDIA MCPs (media and
communications processors).
Depending on the application, NVIDIA SLI can deliver as much as two times the
performance of a single GPU configuration.
Standby mode: in this mode, the video and hard drives shut down; all other
devices continue to operate normally.
