As as sysadmin, Dell hardware is more of a joke the more expensive it is. I contracted for a company that makes pans (I guarantee you have one.) And they used all dells servers standardized across all their infra. Kind of smart except for the part where Dell engineers decided a module that does RAID across 2 SD cards of all things is a good and resilient idea for storing the boot operating system.
If you're a sysadmin in the Pittsburgh area and got woken up by your boss at 5 AM on a Saturday in July 2020 just so you would go plug in a USB in the back of a server, I'm sorry, it's half my fault and half Dell's.
- justinclift 3y agoRAID 0? RAID 1? There's probably a world of difference between them in this use case. :)
- themoonisachees 3y agoRaid 1. There isn't a world of difference. You might be lucky and only one card failed, in which case you might be able to rebuild on another card (with the usual caveat that rebuilding your array puts strain on the other SD card, making it fail (and it does, much more often than an HDD)), but it's a very common occurence for both of them to fail, or for the hardware module that holds them both to fail (impossible to know until after you've changed both cards, it reports simply as a card failure -fun times when the Dell tech didn't bring an extra module!). My contract involved upgrading ESXi on these servers, which is what made me aware of the issue (since ESXi basically lives in ram, if you never reboot you never have a problem). Across maybe 50 servers, at least half of them had a problem with either an SD card or the module for them. Only one had an unrelated problem.
- justinclift 3y agoOh wow, yeah that does sound super shitty. :(
