Raid 10N - American Megatrends StorTrends 1100-P User Manual

RAID 10n

"RAID n" arrays are arrays that support multiple redundancies. RAID 10n supports a
minimum of six disks and supports a maximum of 32 disks.
RAID 10n stripes multiple n-way mirror sets. RAID 10n allows multiple hard disk drive
failures per mirror set, up to n-1 failures in each mirror set that has been striped, where n
is the number of hard disk drives in each mirror set. This array type is useful in creating
exact copies of an array's data using the split command. This array type offers better
random read performance than a RAID 10 array, but uses more hard disk space.
Point Description
uses RAID 10n works best for data storage that must have 100% redundancy of mirrored arrays and
that also needs the enhanced I/O performance of RAID 0 (striped arrays). RAID 10n works well
for medium-sized databases or any environment that requires a higher degree of fault tolerance
and moderate to medium capacity.
strong points RAID 10n provides both high data transfer rates and complete data redundancy. RAID 1n and
RAID 10n are great ways to make backup copies of RAID 1 and RAID 10 arrays. For example,
you can Transform the array into an n array and then Split the array off and hide the Split array
from the OS.
weak points RAID 10n requires twice as many drives as all other RAID levels except RAID 1 and RAID 1n.
hard disk drives Six to 32 hard disk drives.
