Re: [LUG] clustering

[Bill Wilson <bill@xxxxxxxx>]

I have carried out similar exercises with many different operating systems
but not on Linux. However Unix is similar and we found it invaluable.
There is a performance overhead and you need to look at network infrastructure
if you are not going to get into a nightmare. 
It is worth it if we all took that veiw we wouldnt use RAID and every server
we install has RAID. It has saved many customers data. 
Like all technology however it is not the sort of exercise which is cheap
or which can be carried out by unskilled or semi skilled staff and training
and support are expensive to buy.
A typical customer of ours who use this technology would be a retailer who
need the systems running to operate tills etc. Failover systems would be
a prime requirement.
So the answer is yes its worth it if your system being down or loosing data
would cost you money.
