Best way to generate the Sequential numbers : CSUM or IDENTITY columns? - forum topic by Nishant.Bhardwaj

Hi Experts,
My Requirement is to generate the Sequential numbers in Column ..
As It can be done in two ways :
A) define as identity column 
b) CSUM(1,1) 
 
but i got to know from one of my peer that CSUM has some drawbacks like it locks the table. and Identity column has some constraint of upper limit ..  
As i am not sure ,Can any one suggest which would be more good in terms of performance?
Thanks!
Cheers,
Nishant Bhardwaj
