QUESTION 4
What is a valid QoS performance setting?
A. latency threshold
B. IOPS minimum
C. IOPS limit
D. MB/s minimum
Answer: C
Section: (none)
Explanation
Explanation/Reference:
Explanation:
QoS-Limit allows a user to limit either the IOP or MB/s performance of a specific workload. Having the ability
to limit both IOPS and MBs is important as quite often any single workload will have different peaks and
troughs during the operational day. For instance, an OLTP workload maybe very latency sensitive to small
block updates during the working day when rows and tables are frequently being accessed or updated (this will
tend to be very IOP/latency sensitive) yet in the evening the same database maybe receiving feeds from other
systems (or providing bulk updates/analysis or index rebuilds), the same application will cease to be IOP
sensitive and will now be bandwidth (MBs) sensitive. In NimbleOS4 a user can limit a workload by either IOPS
or MBs and also specify limits to both IOPS and MBs. If either limit is reached then the volume will be
restricted accordingly.
