RAID-10 is described as two RAID-0 arrays which are mirrored.
Is this the real implementation?
Common practice is to have multiple RAID-1 arrays which are striped.
That is the recommend in many articles.
Volume migration to recover from failed controller not described in
user guide.
Default drive attribute is write-back. That gives out of the box big
performance numbers but
is less safe.
Manual claims sequential read ahead best performance. Conflicts with
infortrend recommendation.
Manual claims their RAID-5 and RAID-6 has similar performance.
Diagram shows P+Q parity encoding. So unless sufficient cache ram to
buffer multiple
tracks, P+Q RAID-6 has 2 parity writes for each data write.
Claims 3 days battery hold up of cache. Table only shows battery
holding 52 hours with
128M module. What happens when you use 512M module?
thanks in advance.
kind regards
