Service Provider The Service Provider (SP) is a program that resides in the desktop system or server and is

| management information between the managed elements of a network and a network |

| 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, 3, and 5 to RAID levels 10, 30, and 50, respectively. |
