Re: Regarding Hardware configuration for HBase cluster
In a year or two you won't be able to buy 1T or even 2T disks cheaply.
More spindles are good more cores are good too. This is a fuzzy art.
A hard fact is that HBase cannot (at the moment) handle more than 8-10T per server with HBase, you'd just have extra disks for IOPS.
You won't be happy if you expect each server to store 24T.
I would go with more and smaller servers. Some people run two RegionServers on a single machine, but that is not a well explored option at this point (up to recently it needed an HBase patch to work).
You *definitely* have to do some benchmarking with your usecase. You might be able to get away with fewer servers, you need to test for that.

What about high density storage servers that has capacity of up to 24
drives. There were also some recommendations in few blogs about having 1
core per disk.
1TB disks have slight price difference compared to 600 GB. With
negotiations it'll be as low as 50$. Also price difference between 8 core
and 12 core processors is very less, 200-300$.
Do you think having 20-24 cores and 24 1TB disks will also be an option?
