This is due to the XtremIO X2’s ability to maintain operations with double SSD failure protection1. The seventh drive failure would be the point at which the data services are stopped because the system would no longer be able to maintain the required level of redundancy for data protection.The DPG is designed to handle multiple SSD failures by entering different states of degradation:Healthy: Double parity protection.Single Degraded: Single parity protection.Double Degraded: No parity protection.Failed: Data Loss.When the first SSD fails, the system automatically initiates a DPG rebuild to restore double parity protection. If a second SSD fails before the rebuild is complete, the DPG’s usable capacity drops by the capacity of one SSD, but it still maintains single parity protection. Only after the failure of a seventh SSD would the DPG enter a failed state, resulting in the cessation of data services2.NO.26 When an XtremIO X2 array is delivered, where is the cable shown in the exhibit connected?  Middle USB in X3-SC1 only  Bottom USB in X3-SC1 only  Bottom USB in X3-SC1 and X3-SC2  Middle USB in X3-SC1 and X3-SC2 When an XtremIO X2 array is delivered, the cable shown in the exhibit should be connected to the middle USB ports in both X3-SC1 and X3-SC2.
