Gigabytes (10*9) (Billion) of disk storage - most customers
Terabytes (10*12) (Trillion) of disk storage - large customers
Petabytes (10*15) (Quadrillion) of disk storage - a few customers today!
Petabytes (10*15) (Quadrillion) of tape storage - large customers
Exabytes (10*18) (Quintillion) of tape storage - a few accounts by 2001
Zettabytes (10*21) (Sextillion) WW digital data by 2008 - (IDC)
Yottabytes (10*24) (Septillion) - How Long will it take?
And an Exabyte is....?!

Storage investment is tied to specific server
Once server is replaced, storage investment is lost
Migration of data to new server & new storage is required
Underutilized storage can not be shared by other servers or clients
Data in storage can not be accessed by other servers or clients
Storage must be managed as individual entities
Non-centralized management & data protection
Client/server solution has its own dedicated storage

Two Types of Storage Networks
Storage connected directly to IP Networks
Storage connected directly to Fibre Channel Networks
"Versus" may be giving way to "Convergence" One picks up where the other's weakness leaves off.
