I will cheerfully admit that [RedactedCo] has had a few interesting issues with the various brands of storage we've have in the nearly 15 years that I've had the 'owner' hat for the storage systems.
a Netapp FAS eat one of it's controller heads. (We had it set as an active /active pair, so the userbase didn't notice a damn thing.)
a couple Dell Powervault MD3000 arrays; One had a double drive failure on it, eating the raid volume and the backup data spool therein. We had another one that some chucklehead only allocated a single drive to the quorum volume that the database servers that connected to it used for cluster management, and no hot spares on the entire array. (To that appliance's credit, that one drive failed after I had virtualized one of the database cluster nodes that used it; That virtual machine ran as a 'cluster of one' for a few months as we decommissioned the last application from it.)
a Nimble CS1000 getting powered off the hard way when the entire data center shut down from low battery when the site was flooded and the substation in the sub-basement of the building was drowned. (that was a fun couple months, but I was very impressed when it came back up with only minor complaints!)
a brand spanking new Pure storage box that ate not one, but two controllers before deciding the third one was OK. (with some collateral damage of me having to replace a fiber patch cable when the field engineer slammed the insert/extract level over it and destroyed the connector- I was Not Pleased.)
And finally, a Nexsan E18 that one day decided that several of the drives had packed it in (along with one of the controllers burping)- the support engineer set up a zoom meeting, and walked me both through using the super sekret page on the device's web interface to un-fail the drives and re-sync the RAID array, with zero data loss, and getting this very paniced admin out of the 'oh shit oh shit oh shit' anxiety attack that was occurring. :)
a "small business" Qnap appliance decided that it would shut down and never power back up after we rebooted it in order to install firmware updates. While I was able to transfer the disks over it's replacement and didn't lose any data from that adventure, we are looking to move that data... elsewhere.
The one appliance we didn't really have a problem with was the Data Domain, outside of the usual "I'm going to take an hour to re-hydrate a ~800 GB database backup" process and the "you want how much for the year four support renewal!?!?!" shenanigans.
