You are designing a two-tiered Dell EMC SC Series solution that will be optimized for performance. You gather the necessary data from Live Optics and find that the read/write ratio is 80:20. What approach is recommended?
A.
Size Tier 1 for 100% of the adjusted IOPS
B.
Use distributed adjusted IOPS for all tiers
C.
Use distributed adjusted IOPS for Tiers 1 and 2 only
i just took the exam today and passed. There are no questions related to SC anymore. most of the other questions are in Unity and Powerstore as the other person said. most of the questions here are in the exam so this is still valid.
When designing a system with multiple tiers of disk drives, it is a best practice to make tier 1 capable of holding 20% to 30% of the data and provide 100% of the system IOPS needed.
agreed with answer A. midrance_sc_mod_8_sizing_design_v3 (pag.11) "The engineer should design a system to handle all, or nearly all, IOPS in one particular tier"
