The smallest RAID 5 stripe width the system supports is a 4+1. The smallest dynamic pool created with the RAID 5 4+1 configuration is 6 drives. The minimum drive count includes the number of drives specified in the stripe width, plus the hot spare capacity. The hot spare capacity is selected by the user at pool creation, and can either be set to 1 or 2 drives for every 32 drives in the pool. 7.Which onboard Dell PowerStore components does the LCC interface sit between? A. HDD drives and CPU board B. SCM drives and PCIe C. SCM drives and SCSI drives D. CPU board and NVMe drives Answer: D Explanation: The LCC interface sits between the CPU board and the NVMe drives onboard Dell PowerStore components. The LCC interface is responsible for controlling the PCIe links between the CPU board and NVMe drives and allows for communication between the two. It also provides additional features such as Pass DELL EMC D-MSS-DS-23 Exam | Latest D-MSS-DS-23 Dumps & Practice Exams - Cert007 4 / 6 error correction and power management for the NVMe drives. 8.A customer has a Dell EMC Unity 680F array with a single pool consisting of 10 drives configured with RAID 5 (4+1).

A. 0 B. 49 C. 89 D. 99 Answer: D Explanation: The DPE on 480/F, 680/F, and 880/F systems is internally connected to Bus 99 which is a separate bus than the first SAS expansion port that is connected to Bus 0. Therefore, the DPE is recognized by the system as Bus 99 Enclosure 0 while the first DAE connected to the first SAS expansion port would be Bus 0 Enclosure 0. This is different than X00/F, X50F, and 380/F systems. Furthermore, this means that the twenty-five drives in front of the DPE for 480/F, 680/F, and 880/F systems are internally recognized as Bus 99 Enclosure 0 Drive 0 – Bus 99 Enclosure 0 Drive 24. In Unisphere, the drives are seen DPE Drive 0 – DPE Drive 24 11.What is the minimum recommended amount of Flash capacity in a Dell EMC Unity 480 Hybrid pool?
