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.
