SAN/LAN Convergence ?
Source: Gartner Publication ID Number: G00174456
Myth: A Single FCoE Data Center Network = Fewer Ports, Less Complexity and Lower Costs
•
Storage
Protocol debate is heating
up
•
Ethernet outpacing
FC
on speed, performance, costs savings
•
Fiber Channel based SAN tolerates zero risk, business critical apps
•
FCoE
ROI is too weak
•
FC
vs
iSCSI
vs
FCoE
are not significant performance differences !!
•
Organization fight (LAN,SAN) will slow down adoption
Lossless Ethernet adds reliability whatever storage technology…
