18 Comparing how Data ONTAP functions work with disks and array LUNs
RAID group size Maximum and default RAID
group sizes vary according to the
gateway model and the level of
RAID group protection provided
by either RAID-DP or RAID4.
See the Data ONTAP
Storage
Management Guide for more
information.
Maximum and default RAID
group sizes vary according to the
version of Data ONTAP
software. See the gateway
Interoperability Matrix for more
information .
redundant connections to storage You can use either one or two
loops to a native disk. You must
use two loops for redundancy. If
you want redundant loops for an
HA pair, you must use the
Multipath Storage feature. You must configure redundant
paths to an array LUN.
root volume The root volume can be installed either on a native disk or an array
LUN. See “
Considerations when planning for the root volume ” on
page 24 for more details.
SnapLock Compliance Only aggregates created from
storage on native disk shelves
support SnapLock Compliance.
SnapLock Compliance is not
supported in all releases. See the
gateway
Interoperability Matrix
for more information .
Not supported for array LUNs.
SnapMover You can move aggregates and
volumes composed of native
disks only between the nodes of
the HA pair. You can move aggregates and
volumes composed of array
LUNs between any of the
gateways in the neighborhood.
See the gateway
Interoperability
Matrix to determine which
versions of Data ONTAP
support SnapMover.
