質問 # 33
An application is running on XtremlO replicating to another XtremlO using RecoverPoint with the following:
Journal size= 1.05 * (write traffic) * (rollback time in seconds) / (1 - image access log percentage) + (reserved for marking)
. Average write traffic = 5 Mb/s
. Required rollback time = 24 hours
What is the minimum required size for the Journal volume using the default parameters?
- A. 60 GB
- B. 57.3 GB
- C. 72.4 GB
- D. 10 GB
正解：C
解説：
To calculate the minimum required size for the Journal volume, we can use the provided formula and input the given parameters:
Average Write Traffic: 5 Mb/s
Required Rollback Time: 24 hours (which is 24 * 60 * 60 = 86,400 seconds) Default Parameters: Assuming the image access log percentage is 20% (which is a common default), and the reserved for marking is negligible.
Using the formula:
\text{Journal size} = 1.05 \times (\text{write traffic}) \times (\text{rollback time in seconds}) / (1 - \text{image access log percentage})Journal size=1.05×(write traffic)×(rollback time in seconds)/(1-image access log percentage) We plug in the values:
\text{Journal size} = 1.05 \times (5 \text{ Mb/s}) \times (86,400 \text{ seconds}) / (1 - 0.2)Journal size=1.05×(5 Mb/s)×(86,400 seconds)/(1-0.2) Converting Mb to GB (1 Mb = 1/8,000 GB):
\text{Journal size} = 1.05 \times (5/8,000 \text{ GB/s}) \times 86,400 / 0.8Journal size=1.05×(5/8,000 GB/s)×86,400/0.8
\text{Journal size} = 1.05 \times 0.000625 \text{ GB/s} \times 86,400 / 0.8Journal size=1.05×0.000625 GB/s×86,400/0.8
\text{Journal size} = 1.05 \times 54 \text{ GB} / 0.8Journal size=1.05×54 GB/0.8
\text{Journal size} = 70.875 \text{ GB}Journal size=70.875 GB
Since we need to round up to ensure we have enough space, the minimum required size for the Journal volume is approximately 72.4 GB.
This calculation ensures that the Journal volume is adequately sized to handle the write traffic and maintain the required rollback time, providing a buffer for the image access log1.
