Upgrading To Data Ontap 8.0.1 Increases Volume Capacity After Deduplication; Maximum Simultaneous Flexclone File Or Flexclone Lun Operations Per Storage System; Support For Flexclone Files And Flexclone Luns On Vfiler Units; Increased Maximum Raid Group Size For Sata Disks - IBM N Series Manual

Upgrading to Data ONTAP 8.0.1 increases volume capacity after
deduplication
After you upgrade to Data ONTAP 8.0.1 and later from an earlier release of
Data ONTAP, you can increase the deduplicated volume size up to 16 TB on
all supported platform models that support Data ONTAP 8.0.1.
Maximum simultaneous FlexClone file or FlexClone LUN operations per
storage system
Starting with Data ONTAP 8.0 7-Mode and later, you can simultaneously run
a maximum of 500 FlexClone file or FlexClone LUN operations on a storage
system.
For more information about FlexClone files and FlexClone LUNs, see the Data
ONTAP 8.0 7-Mode Storage Management Guide.

Support for FlexClone files and FlexClone LUNs on vFiler units

In Data ONTAP 8.0.1 and later release of the 8.0 release family, the FlexClone
file and FlexClone LUN commands are available in the both the default vFiler
context.
You can use FlexClone files and FlexClone LUNs feature to create writable,
space-efficient clones of parent files and parent LUNs within a vFiler unit.
Storage owned by a vFiler unit cannot be accessed or discovered from other
vFiler units by using the FlexClone file or FlexClone LUN commands.
For more information about FlexClone files and FlexClone LUNs, see the Data
ONTAP 8.0 7-Mode Storage Management Guide.

Increased maximum RAID group size for SATA disks

Starting in Data ONTAP 8.0.1, the maximum RAID group size allowed for
ATA, BSAS, and SATA disks has increased from 16 to 20 disks. The default
size remains the same, at 14 disks.

Ability to decrease maxfiles

Starting in Data ONTAP 8.0, you can decrease the value of the maxfiles
parameter for a volume, as long as you do not decrease it below the current
number of files stored in the volume.
In previous versions of Data ONTAP, you could increase the value of the
maxfiles parameter, but not decrease it.
