Supermicro SC217 Chassis $919
Supermicro H8DGT Motherboard x4 $1700
AMD Opteron 6128 CPU x8 $2288
4GB DDR3-1333 ECC Registered RAM x32 $4256
Seagate Momentus XT 500GB x24 $3240
Total: $12,403
Okay, that's a lot of money, yes.
But what you get for that is a 64-processor server with 128GB of RAM and 12TB of disk with a 96GB non-volatile cache.
Which fits in 2U of rack space.
It actually has room for 48 CPUs and 512GB of RAM, but that would blow the price out to $33,555, which is a wee bit expensive.
There's also a version of the motherboard with built-in QDR Infiniband, but it costs twice as much.
Or this, for storage:
Supermicro 36-bay chassis with DP motherboard and RAID controller $2569
AMD Opteron 6128 CPU x2 $572
4GB DDR3-1333 ECC Registered RAM x8 $1104
Seagate Barracuda LP 2TB x36 $4140
Total: $8385
Or finally:
Supermicro 6-bay chassis with QP motherboard: $1993
AMD Opteron 6128 CPU x4 $1144
4GB DDR3-1333 ECC Registered RAM x32 $4256
Seagate Barracuda ES.2 1TB x6 $954
Total: $8347
I don't need 72TB of disk space, but I know someone who does.

I was looking at using MongoDB for Minx; unfortunately, it doesn't like OpenVZ at all; if your database is bigger than the memory available to the virtual machine, MongoDB will crash. (It's a known bug and they're working on it, but it would require a whole new storage engine to fix.)
This system is actually four 16-core 32GB servers packed into a 2U chassis. So one for the applications, one for MongoDB, and two for Counterstrike.

Naturally, the developers of Keyspace are dropping it to move on to a new project.

I did look at Couchdb, but it doesn't really give me anything I need.
The simplest solution I can see that gives me everything I need would be Mongodb + Redis + Xapian + Memcached. Which is kind of a mess and would require a non-OpenVZ server for MongoDB, but should at least work.

It's an indication of just how fast and far computer science has grown that there are now such a wide variety of sub-specialties which are so different from one another that experts in them cannot converse intelligently.
When I was still able to work, my area of expertise was embedded software. I know nothing about databases. It's all greek to me.
