Emerging Standards Impact on Storage Networks
Fabric wars - Cisco battles the established players. How do you win?
CIM for storage - When will you see it? What will it do for you? Will you be better off choosing CIM-compliant storage?
Single vendor support for multi-vendor, storage networks vs. vendor consortiums - Which is better? What is the SSF and can it help you?
IP Storage - The hype says no interoperability issues here. Are there problems lurking in the underbrush?

The Road to Multi-vendor Fabric Extension
FC-SW-2 • Long road to adoption
• Backward compatibility requirements result in proprietary vs. open systems modes
Fabric extension consequences• Large layer 2 network
• More of the fabric exposed to error conditions
FSPF-BB to the rescue?• Proposed standard for creation of autonomous regions

Bridging SAN Islands: FCIP vs. iFCP
FCIP –• Uses tunneling
• Fault isolation can be an issue
iFCP – • Uses “conversion”
• Achieves problem isolation but potentially exposes
SAN to network administrators
• Nishan now seeing major spike in demand for iFCP

It’s a high stakes chess game
The Winner could dominate more than
storage networking
Will VSANs rule?

What is SMI-S?
The Storage Management Initiative Specification (SMI-S)
F.k.a. Bluefin, a.k.a CIM for storage
Lives within the SNIA’s Storage Management Forum (SMF)
SNIA working to become accredited ANSI Standards Developer

Can SMI-S Succeed?No
• Vendors won’t cooperate
• Progress will be too slow
• Result will be of marginal value (i.e. its vendor hype)
Yes• Its in the commodity realm and commodities win
• Users will perceive value in a common management interface standard
• It makes life easier for vendors too
Its up to you

iSCSI – No Interop Issues Here ….Right?
Recommendations:• Stay tuned to the Microsoft channel for iSCSI
“certification” if you plan heavy iSCSI deployment
in MS application environments
• Monitor the progress of the iSCSI Management API

Can Interoperability and Security Co-exist?
IEEE – Searching for a standard
encryption method• Proposed solutions now on the table
• One method: use open source-developed code with
unique user-created keys to “unlock” the data
Hosted by
Can Interoperability and Security Co-exist?
Recommendations: • Investigate potential conflicts with existing SAN
security features (i.e. Zoning and Masking)
• Investigate impact on data life cycle management
infrastructure and strategy (i.e. exposure to data
loss long term)
• Investigate potential for vendor lock-ins
• Whatever you do, don’t lose the keys
