Converged Web-Scale DatacentersBlade servers are passé, rackmounts are in!
Business Agility
Rapid Scale
Cost Efficiency
Design Goals• No single point of failure• No single point of bottleneck• Always-on systems• Deep Analytics across all SW/HW components• Interactive visualization of entire datacenters
Fundamental Assumptions• Unbranded x86 servers: fail-fast systems• No special purpose appliances• All intelligence and services in software• Linear, predictable scale-out

Flattening of InfrastructureBig Data Folks: “What in the world is a SAN… and a blade server?!”
“The practitioners of big data are hostile to shared storage.
They prefer server-attached storage… The perception of
SAN and NAS is that they are slow, complex, and above all,
expensive. These qualities are not consistent with big data
analytic systems that thrive on system performance,
commodity infrastructure, and low cost.”
- Wikipedia (“Big Data”)

Flattening of InfrastructureDev Ops: “What in the world is a blade server?!”
Massive democratization of
infrastructure
Dev Ops takes charge: autonomy,
independence, access
Application owners become
paramount

Flattening of InfrastructureA brief history of the Post-SAN-Post-Blade-Server Converged era
Monolithic mainframe-like systems were
banned
Grow-as-you-go clusters are in vogue
Network topologies have been flattened

With software, scale-out, not scale-up
Convergence 1.0 to 2.0From “Duct Taped” hardware to true (hyper)convergence
