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


Multiple applications
(Virtual Machines)
residing
on same
server


Shared on
-
demand
computing resources


Less
servers
–

lower power consumption


Static servers
for
1 single application


Dedicated
per server computing resources


Low network bandwidth requirements


Too many servers
–

high power consumption

Server Mobility
-

Virtual Machines


Static
Servers
–

no mobility


Manual administrative actions required for
moving applications from one Server to
another



Service down while moving

Network



Virtualization
enables machine mobility


Mobility across:


Same Data Center


Multiple Data
Centers


New challenges


MAC address scalability


Dynamic
network updates



overload, locate VM

Needs: Highly
scalable dynamic network, Application as a Service

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…
