For workloads with highly random I/O, such as virtualization, what data profile for log SSDs
provides the BEST performance for 7000-series systems with Log SSDs?
A.
Mirrored
B.
Striped
C.
Double parity RAID
D.
Single parity RAID
Explanation:
Striped.
Data is striped across disks, with no redundancy whatsoever. While this maximizes
both performance and capacity, it comes at great cost: a single disk failure will result
in data loss. This configuration is not recommended, and should only be used when
data loss is considered to be an acceptable trade off for marginal gains in capacity and
performance.
