Oddly, out of our 8 netapps, the only one that hasn't had a RAM or Disk failure is the one with Kingston RAM, Dallas Semiconductor NVRAM and a number of Seagate drives, all sourced as 'third party'.
Of our 4 new f230's we got about 5-6 months ago, we've had one dead NVRAM board, about 2 with bad RAM and I believe 2 ill disks. These are just off the top of my head and possibly not counting the DOA RAM issues and another dead NVRAM board I seem to remember hearing about. Most of these were barely even cracked open by us since receiving them from NetApp but the problems persisted even after reseating, etc.
Humourously, the ones with bad RAM sure worked swell when we stuffed them with cheap Kingston RAM while waiting for the NetApp replacement 'Heavily Tested and Approved' RAM was being shipped.
We paid extra for this?
