Well, I have some good old hard drives and a good idea is to combine them into an array.
For example:
250G300G500G1000G2000G
(There is also a 3000G drive, but I'll save it for regular backups).
What I want: a cheap Linux programmatic way to combine them with some redundancy (of course, I'm willing to lose 50% of the space).
This would be the perfect solution if minimal human power consumption is needed: I want to just add devices to the pool and choose K-security up to 2 or maybe up to 3 (so that each block is stored on at least 3 disks). It would be even better if the thing has fault tolerance and can reallocate blocks if one of the disks fails.
Yeah, like HDFS or Vertica, but for mere mortals :)
Of course, this will be a very cheap solution without ECC and HW RAID.
