FC Complexity Conclusion
Configuration & mgt intuitive
Limited specialized knowledge req’ts
Not as significant of an issue• Depends of the vendor
9/20/3004 Where FC is Headed 22
Change ManagementDifficult & Problematic?
Historically: yes• Lot of coordination
Servers, storage, SAN, cables & facilities
• Re-architecting
Switch ports have to be reallocated for ISLs
Zones, cabling, and LUN masking must be redone
• Followed up with shakedown & troubleshooting
Sometimes requiring back out of the change
9/20/3004 Where FC is Headed 23
Change MgtRequirements?
Market requirements include• Automation
• Negative impact minimization
• Audit trail
• Change simulation, planning, & validation
• Correlation of LUN maps, zones, pathing policies
• Work plans for all of the departments involved
• Simple, “brain dead” trouble shooting

FC SAN Scalability:Difficult & Problematic?
Historically a definitive yes:• Fabric disruption propagation
• Large fabrics increase latency
More intra-fabric switch ASIC hops
• Databases bloat
• QoS has been nominal
• Change mgt problems exacerbate as fabrics grow
• Troubleshooting can take a very long time
9/20/3004 Where FC is Headed 27
Fabric Disruption Propagation
Fabric disruptions anywhere…• …propagate throughout the fabric everywhere
• RSCNs
Zone changes, add switches or HBAs
9/20/3004 Where FC is Headed 28
Traditional Approaches have led to Urban Sprawl: a.k.a SAN Islands
IT is dynamic• Most organizations do not plan well
Minimizes disruption effects of change• Doesn’t eliminate disruptions
This becomes…
…this
9/20/3004 Where FC is Headed 29
Issues with SAN Islands
Limits SAN benefits• Storage consolidation limited by island
• Management touches expand
9/20/3004 Where FC is Headed 30
Large Fabrics = > Inter-Switch ASIC hops
Hop number affects latency• Latency is cumulative
• Affects end user response times
Users demand predictability• Mesh and/or SAN islands =
unpredictable
Locality = predictability again
• Core-edge = predictable
9/20/3004 Where FC is Headed 31
SAN Database BloatAs fabrics get larger• FSPF databases get larger…and slower
• Name services get larger…and slower
• SAN performance degrades
9/20/3004 Where FC is Headed 32
Lack of Effective QoS
Reduced application throughput• Manual SAN tuning
• Very difficult for larger SANs
9/20/3004 Where FC is Headed 33
Manual Change Mgt = > $OpEx
Larger SANs mean • > complexity
• > % for human error
• > time troubleshooting
• < less uptime
9/20/3004 Where FC is Headed 34
Lengthy Troubleshooting
Increases $OpEx• Reduces SAN flexibility, growth, & changes
• Increased application downtime
9/20/3004 Where FC is Headed 35
