Total Cluster Storage = (1-o)m(t-L)/2 |
Total Storage Per Machine = (1-o)m(t-L)/(2t) |
Where:
L = Number of machines that you can afford to loose and retain cluster stability (defualt is 1)
t = Total Number of Machines
m = Memory Per Machine
o = Overhead fraction. Default being 0.3

I’ve worked with software and with computers for a while now. Long enough to sometimes be useful but not so long as to have lost interest.
My experiences of late have largely focused around distribted caching, in particular with Coherence, and this has inevitably shaped my understanding of systems, so keep that in mind as you read on.
The articles here really fall into two categories: Coherence stuff that I know, and wider issues of distributed computing, running projects and the like, which I find interesting. You can read a little more about me here.
