devopstips:

According to this writeup, new features include the ability to use SSD drives as caches for other storage devices, the ability for multiple sockets to attach to a single TCP or UDP port with kernel-level loadbalancing, btrfs gains the ability to use RAID-5 and RAID-6, and support for new hardware.

Do you have a lot of data, but not much money? Check out these storage servers designed by Backblaze…..they fit 45 (!) 3.5” SATA drives in a 4RU case. That’s 180TB, if you use 4TB drives, or 135TB, using 3TB drives.

The plans, including the CAD drawings, are available freely, and the servers can be built quite cheaply, especially when compared to commercial solutions. 

If you’re not feeling that adventurous, you can buy pre-built machines from Protocase for around $5000, not including the drives. While that’s a lot of money for a desktop, it’s nothing compared to what EMC or NetApp would charge for the same amount of storage. 

I’ve been using these “pods” in production, serving streaming video content, for more than a year. They’re really nice, especially using a modern filesystem like btrfs (in Linux) or ZFS (in BSD or Solaris).

Suppose you have a secret you wish to transmit to $n$ people, but in such a way that all of those $n$ people must collaborate in order for the secret to be revealed. In other words, it must not be possible for even $n-1$ of those people to obtain the secret, even partially, if the $n$th person…
