You are designing a Dell EMC Unity solution. You need to predict its expected performance based on workload, number o and type of drives, and RAID protection. Which design path on the Midrange Sizer should you take?

correct > A. System Designer path., choose eg. Unity XT 380F, “Storage Pool”, workload eg “80%R, 20%W”, Block size “8k”, Pool Info. “Drive type” eg 1.92TB SAS, RAID type eg“RAID 6”, SparePolicy, DriveCount, RAID width, UseableCap, EffectiveCap, IOPS
IF choose> B. Apps Oriented path, need to choose “ApplType” eg. “MS Exchange/FileShare/SAP_HANA, etc”, DataReduction-Enable or Not, Instance Use-Pdtn? Type-ScaleUP or OUT? Standby Node count. … So NOT.
IF choose> C. Quick Config path, you choose “Capacity(TB) useable/effective”, IOPS, System Models, RAID type, Workload (for Unity or SC), Block size, drive type.
>>>>>>>>>>>>> A and C seem corect!
11. What is an achieved benefit of distributed sparing on a dell emc sc series array?
Global sparing
Non-disruptive sparing
Out-of-folder sparing
Improved I/O efficiency
Its tricky question, System designer also give you the option to choose workload, difference being the you have to choose a system before you can configure anything , so id say given the information in the question A or C
B should be the answer.
the question says "performance based on workload". System designer is not based on "workload". you provide total IOPs / storage you need and it spits out a report.
