Service Provider
The Service Provider (SP) is a program that resides in the desktop system or server and is responsible for all DMI activities. This layer collects management information from products (whether system hardware, peripherals, or software), stores that information in the DMI database, and passes it to management applications as requested.
SNMP | Simple Network Management Protocol. The most widely used protocol |
| for communicating management information between the managed |
| elements of a network and a network manager. SNMP focuses primarily |
| on the network backbone. The Internet standard protocol that manages |
| nodes on an Internet Protocol (IP) network. |
Spanning | Array spanning by a logical drive combines storage space in two arrays |
| of disk drives into a single, contiguous storage space in a logical drive. |
| MegaRAID logical drives can span consecutively numbered arrays that |
| each consist of the same number of disk drives. Array spanning |
| promotes RAID levels 1 and 5 to RAID levels 10 and 50, respectively. |
| See also Disk Spanning. |
Spare | A disk drive available to back up the data of other drives. |
Stripe Size | The amount of data contiguously written to each disk. You can specify |
| stripe sizes of 4, 8, 16, 32, 64, and 128 Kbytes for each logical drive. For |
| best performance, choose a stripe size equal to or smaller than the block |
| size used by the host computer. |
Stripe Width | The number of disk drives across which the data is striped. |
Striping | Segmentation of logically sequential data, such as a single file, so that |
| segments can be written to multiple physical devices in a |
| fashion. This technique is useful if the processor can read or write data |
| faster than a single disk can supply or accept it. While data is being |
| transferred from the first disk, the second disk can locate the next |
| segment. Data striping is used in some modern databases and in certain |
| RAID devices. |
Terminator | A resistor connected to a signal wire in a bus or network for impedance |
| matching to prevent |
| connected across the end of an Ethernet cable. SCSI buses and some |
| LocalTalk wiring schemes also require terminators. |
