Using Adaptec Storage Manager – Browser Edition
■
Stripe Size
—For a RAID 0, where data is striped across
multiple drives, stripe size determines how much data is
written on each drive for a given stripe.
Note:
Adaptec recommends that you do not change the
stripe size.
For RAID 1 arrays, which need to be initialized, advanced options
allow you to select which method is used to initialize the array and
set the priority of the initialization task.
The Advanced area of the Create Array wizard may offer the
following initialization options:
■
Build
—For a RAID 1, the data from the primary drive is copied
to the secondary drive.
The advantages of building an array are that the array is
immediately available for use, and that when the build is
complete, the array operates at maximum performance. The
disadvantages are that building takes some time, for a large
array possibly many hours, and performance is impacted until
the build completes.
■
Clear
—In this case, the contents of all the drives are cleared.
The advantages of clearing an array are that the process is much
faster than building and when completed, the array operates at
maximum performance. The disadvantage is that the array is
not accessible until the clear completes.
■
Quick
—In this case the array is immediately available. The
advantage of quick initialization is that the array is immediately
available with no on-going build.
■
Initialization Priority
—This drop-down list allows you to
adjust the priority of the initialization task. The default is High,
which means that the initialization completes as fast as possible.
The other options are Medium and Low. Depending on what
other tasks are running on the controller, selecting either of
these options lengthen the initialization time.
