Transcript An Introduction to the Storage Bridge Bay Specification

An Introduction to the
Storage Bridge Bay
Specification
1
Key Points
 A new
open platform for storage
innovations to benefit customers through
standardization:


Accelerating the availability of new
technologies such as:
• iSCSI
• SAS
• Storage applications (e.g., VTL, archive)
Delivering increased quality and
affordability
2
Broad Industry
Collaboration
Membership is growing daily.
Expect steady membership growth to continue.

What SBB is

A specification created by a non-profit working
group that is defining a mechanical/electrical
interface between a passive backplane drive
array and the electronics packages that give the
array its “personality”
