Coda File System

Setting up a large file server

After having played around with Coda for a week or so now, I'm ready to try 
setting it up on a more realistic situation. I want to use it in an 
installation with 3 replicated servers and 10 clients. I'm currently using a 
single server with approx 500 Gb of disk.

My question is; how should I configure the SCM when I set it up initially ? In 
particular, I would like some advice about the RVM settings and how to 
structure the volumes on my servers.

As I understand it, the /vicepa partition is where the actual user data is 
contained. The RVM data and log partitions contain the meta-data associated 
with the user data.

I'm concerned at the requirements for sizes of the RVM log and data partitions 
as I'm going to be storing a large number of small files. The vice-setup 
script indicates the RVM log partition/file should be 30M or less. Then the 
RVM data size seems to max out at 1Gb which (as I understand) should handle 
roughly 15-20Gb of user data.

Given that my existing file-server is handling an order of magnitude more 
data, is Coda a suitable solution or should I be investigating alternative 
distributed storage solutions ? 

Thanks in advance.
