"...but Bergman said he’s OK with his drives failing, and has planned for that in his network architecture (he uses RAID 0), so Dell is “optimising for something we really don’t care about.”"
I am pretty sure all of this is just taken out of context by an ignorant journalist, but raid 0 is striping, not mirroring, so if one drive goes, the whole array goes. Even if it was supposed to be Raid 1, I hope that they also have real backups (aka raid is not a backup).
- ghshephard 17y agoWe use RAID 0 all over the place. Great Performance and no additional overhead on disks - Raid 1 requires you purchase twice as many disks, raid 5 has the 1 disk penalty (which, for 3 disks, means 33%). Disks have become pretty reliable lately, and, if you have a redundant machine architecture, you simply boot the bad disk and rebuild the machine. So, I'm guessing based on the context of the article, that yes, Raid-0 is precisely what they are using.
- russss 17y agoBy RAID 0, they likely just mean "no RAID", where the redundancy is across machines, not just disks.
