I'm having a 3250 array with ONTAP 8.2.P3. I wanted to upgrade to ONTAP version 8.2.1. I can understand few bugs must be fixed in 8.2.1 against 8.2.P3.Request you to write to me what major benefits i'm going to get/see after the upgrade.
Convert 32-bit aggregates to 64-bit aggregates without adding disks
Addition of the Automated Workload Analyzer which provides a real-time workload analysis to estimate the recommended Flash Pool size and estimated cache hit rate
Support for VMware vStorage over IPv6
CIFS (SMB) default TCP Window Size inceased to 64,240. If you have modified the current CIFS TCP WIndow size from the current default value of 17,520, your custom value will be retained with the upgrade to 8.2.1.
