An enterprise customer plans to purchase Huawei Oceanstor 9000 to meet its 10PB data storage requirements. The customer chooses the C36 node of Oceanstor 9000. The node is equipped with 4T SATA disks, and the nodes use 4+2 distributed RAID storage. Assuming that the system loss (including metadata and system data possession, hard disk loss, etc.) is 10%, theoretically, how many C36 nodes does the customer need to purchase at least to meet their business data storage needs?
