Enhancements That Allow You To Specify Ssl Versions; Root Aggregate Snapshot Reserve Values Reduced - IBM N Series Manual

v Hardware-assisted takeover is available on systems that support the SP and
have the SP configured.
For more information about the SP, see the Data ONTAP 8.0 7-Mode System
Administration Guide.
For more information about hardware-assisted takeover, see the Data ONTAP
8.0 7-Mode High-Availability Configuration Guide.
You must ensure that your system has the latest SP firmware version. You can
use the sp status command to display the SP firmware version on your
system, and, if necessary, update the SP to the latest version that is available
for download on the IBM N series support web site, which is accessed and
navigated as described in "Websites" on page 149.
For instructions on how to download and update the SP firmware, see the
Data ONTAP 8.0 7-Mode Upgrade and Revert/Downgrade Guide.

Enhancements that allow you to specify SSL versions

If your storage system has the SSL protocol enabled, you can further specify
the SSL version to use by using the ssl.v2.enable and the ssl.v3.enable
options.

Root aggregate Snapshot reserve values reduced

The root aggregate and root volume Snapshot reserve values for new storage
systems have been reduced starting with Data ONTAP 8.0.1.
To increase the amount of usable space on the storage system while still
retaining all the benefits of volume Snapshot copies, IBM ships all new
systems running Data ONTAP 8.0.1 or later with the following new Snapshot
reserve values:
v Snapshot reserve for the root aggregate is set to 0%.
The previous value was 5%.
v Snapshot reserve for the root volume is set to 5%.
The previous value was 20%.
No other aggregates or volumes are affected, nor is the default Snapshot
reserve value for newly created aggregates or volumes.
Existing systems, and systems configured at the factory to run MetroCluster,
are not affected by this change.
