CORRECT TEXT
An oil company moves geological data between their offices in Dubai and Houston for redundancy. The data is accessed via NFS mounts on a cluster of three 10GB connected Linux servers at each location.
A series of cron jobs are leveraged to replicate data from data storage pool A in Dubai to data storage B in Houston and from data storage A in Houston to data storage pool B in Dubai.
Data in storage pool A is read-write, updated by 50 cellular connected data collector running in the field, and deleted after 30 days.
Data in the storage pool B is read-only, queried by the firm’s analytics team, and copied to a cloud-based archive repository every 30 days.
The total amount of data in pool A in Dubai is 1.5PB
The total amount of data in pool B in Houston is 500TB
The data is not expected to grow in the next 12 months and is compressed by the application.
