In my experience with NetApp FAS Series, I found the CLI commands to be very valuable and easy to understand, unlike other storage products. I can use just the show command to see something, and it helps me narrow down issues quickly, which makes CLI easy for me. I use snapshot technology in NetApp FAS Series. The snapshot technology has helped me in data protection. For example, during an upgrade of our ONTAP version at my workplace, it did not reflect properly despite the upgrade being completed. I had a VMware snapshot from another team, and that was helpful for me to retrieve the data right after the failed upgrade. I use snapshots frequently, maintaining a snapshot policy of 28 days which allows me to help users retrieve files they are unable to access. In maintaining data integrity in my operations with RAID DP, I see that it helps me significantly. If two or more disks fail, it gives me time to work on replacements. If only one disk fails without RAID DP, I would lose data and connection, but with RAID DP, I have that time to act without losing or making data unavailable to users. The data management features of Data ONTAP are highly valuable for my organization in terms of data security and compliance. I have not experienced data loss or unavailability as I have SnapMirror, Snapshot, and SnapVault in place. This helped prevent escalations. While I faced some access issues or slowness, severe data loss has not been an issue, and I resolve issues within one to two hours with the data integrity these tools provide.
