It Ain’t Software Defined Until You
Unbundle the Platform
Shrijeet Mukherjee, VP Software

2. Data Center Trend
 Complex applications on generic infrastructure
 Look at the x86 server market
Unbundled OS + Apps
 operating systems
closed – Windows, Solaris
open – Linux, BSD, etc – RedHat, Debian
•
•
 applications
•
•
closed – SAP
open – Hadoop
 Infrastructure not modified to enable app
deployment

3. Software Defined Networks
 Efficiency lies in a “Software Defined
Data Center”
 No perfect networking solution
 Choose solution (Openflow, traditional L2/L3)
More about choice than about
API’s and architectures

6. So .. What Does it Take ?
“I want to run NX-OS on my Dell S6000”
 Interface standards matter




But not where you think
Boot Loaders
SKU’s, UUID’s etc
Sensors and other peripherals
 The box does more than Networking

PC spec, ACPI, BIOS spec enabled x86 ecosystem
Software Vendors like Microsoft were key drivers
