H13-629_V3.0 Question #858: Real Exam Question with Answer & Explanation

A security company needs to expand a new data center to meet storage needs due to the increasing number of cloud users. It plans to purchase flash storage devices to support image data storage. The site plans to support 300 video signals, each with a traffic of 1.5Mbps, and requires that each video signal be retained for at least one month. Known: 1. The nominal capacity of a single hard disk is 931 GB, and two coffer disks are configured, each with a capacity of 480 GB. The coffer disk is not used as a member disk of the RAID group. 2. The server uses Windows operating system and NIFS as the file system, with a space occupancy rate of approximately 0.01%; 3. Due to the large data write traffic and large storage space occupied, based on cost and data security considerations, the RAID strategy will adopt RAID5, with a planned configuration of 8D+1P, using the default hot spare strategy (equivalent to creating a hot spare disk for each RAID group). What is the estimated total capacity required for this site?
