Updates to With Varying Frequency will have to wait until an unplanned Server Room project is finished.
RAID (Redundant Array of Independent Drives) setups are supposed to be pretty fail-safe.
That is until some of their components stop working.
Not an end-of-the-world dead-drive thing like by MacBook had been prone to, but a scramble to find appropriate parts to get the server back in service.
I often buy two of anything I consider important & hard to replace on very quick order – two identical hunting rifles, two identical competition pistols, two identical HF rigs, laying in two identical feed-lines, laying in two identical rotor cables….
I’ve had people tell me that this is overkill, and that I am not consistent (yes I don’t have two identical motorcycles, or two identical Suburbans or two identical “this or that”).
But usually I never have a real “down” if gear fails.
The server demanding attention is a legacy machine, and at the time the costs of an idled spare machine were not in budget.
And of course the idea was you could get spares within a day or two.
Well time has moved on, and spares in a day or two isn’t acceptable downtime anymore. Vintage Spare (yes anything over 5 years old is vintage in the world of computers – some say anything more than 24 months from production is obsolete “old stuff!”) parts are hard to come by.
Maybe having two identical, regardless of cost, isn’t such a bad idea after all?
