What is a consideration when sizing a Dell EMC SC Series system for capacity?
- A . Read/Write ratio
- B . IOPS
- C . Page size
- D . RAID overhead
D
Explanation:
(Input/Output Operations Per Second) is a key consideration when sizing a Dell EMC SC Series system for capacity. IOPS is a measure of the performance of a storage system, and a higher number of IOPS generally indicates better performance. Other factors to consider would be the number of disk drives, RAID configuration, and storage capacity required for the specific use case.

What is a consequence of using an 800 GB drive and five 400 GB drives in a Dell EMC Unity XT dynamic pool?
- A . Extents 9 C 14 are used to create a RAID Group
- B . Unisphere short strokes the 800 GB drive to 8 extents
- C . Extents 9 C 14 are marked unavailable until more 800 GB drives are added
- D . Extents 9 C 14 are marked unavailable and can never be recovered
C
Explanation:
The entire capacity of a particular drive size is only available when the drive count within the drive partnership group for the drive in question matches or exceeds the stripe width plus one drive. It is not recommended to mix different size drives of the same type for this reason, unless an adequate number of drives are available to meet or exceed the stripe width plus one drive requirement
