# Method used to calculate the RGU position

81

The installation point of the buried RGU on the fiber span leading to the receive-end station must be carefully calculated. The designed distance of the fiber span from the RGU to the receive-end station, and the designed loss of this post-RGU fiber span must be determined based on the system configurations and the total line loss (deriving from factors such as the span length and fiber loss factor).

Relationship between the gain and noise figure of an EDFA
The noise figure (NF) of an EDFA can be calculated according to the following formula: NF = Pase/(H*V*Δv;V*G) NF: noise figure Pase: noise per 0.1 nm H: Planck constant [6.6260755 ± 0.0000040) x 10-34J-s] V: signal frequency Δv: 12.5 GHz (0.1 nm) G: OA gain Obtain the logarithm: Pase = NF + G �?58 According to the preceding information, a larger OA gain results in a larger NF.

Method used to calculate fiber loss
In general, the fiber loss budget for the 1310 nm wavelength is 0.45 dB/km and that for the 1550 nm wavelength is 0.275 dB/km.

Method used to calculate a linked clone VM's storage resources
The storage resources required by a linked clone VM are calculated as follows: Formula: ROUNDUP (N/128, 0) x Size of the base volume + N x Average size of delta volumes. The average size of delta volumes needs to be calculated based on the site situation. Generally, the estimated average size is 5 GB.

Method used to calculate RAID capacity
If the number of RAID member disks is N (excluding hot spare disks), available capacity of RAID 0 = N x disk capacity. Available capacity of RAID 1 = N x Disk capacity/Number of mirror groups Available capacity of RAID 3 = (N-1) x Disk capacity Available capacity of RAID 5 = (N-1) x Disk capacity Available capacity of RAID 6 = (N-2) x Disk capacity Available capacity of RAID 10 = N x Disk capacity/Number of mirror groups Available capacity of RAID 50 = (N-2) x Disk capacity
