Server Virtualization


Average CPU Utilization is: 3.38%


Peak CPU Utilization is: 8.75%


*Source: Dimension Data , 2010

Needs:
Higher computing ROI, less servers, less energy

Less
servers

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…
