It is very important to note which disk is the source disk (the one containing all of
the information to be migrated) and which one is the target disk. On a RAID Ready
system, this can be determined by making a note during POST of which port (e.g.
Port 0 or Port 1) the single disk is attached to.
You can also use the Intel Application Accelerator RAID Edition utility before the
second disk is installed to verify the Port and serial number of the drive that
contains all the data.
are similar to RAID-0 reads, writes can be either rather
expensive (requiring read-in prior to write, in order to
be able to calculate the correct parity information), or
similar to RAID-1 writes. The write efficiency depends
heavily on the amount of memory in the machine, and
the usage pattern of the array. Heavily scattered writes
are bound to be more expensive.
RAID 10
(Mirrored Stripes)
–
A RAID 1 array of two RAID 0 arrays.
†
Strip Sizes:
Select the desired strip size setting. As indicated, the optimal setting is 128KB.
Selecting any other option may result in performance degradation. Even though
128KB is the recommended setting for most users, you should choose the strip
size value which is best suited to your specific RAID usage model. The most
typical strip size settings are:
4KB
: For specialized usage models requiring 4KB strips
8KB
: For specialized usage models requiring 8KB strips
16KB
: Best for sequential transfers
32KB
: Good for sequential transfers
64KB
: Good general purpose strip size
128KB
: Best performance for most desktops and workstations
