Architectures in comparison
Classical LAN, server, SAN, storage
LCM for multiple components (different LC)
2 separate networks to maintain
HW-defined
Scalability by adding multiple components, primarily separately
Storage activities are separated from servers
Established for many years
Hyper-converged LAN, server (includes storage)
LCM for less components
More powerful LAN required
SW-defined
Scalability by adding servers, primarily linear (compute & storage)
Servers are involved in storage activities
To be considered when sizing compute resources
Entered the market some 3 years ago

What do these differences mean for you?
Classical To be used for general purposes
Physical, virtual, multi-hypervisor
HW dependence, primarily related to storage
Well-known SW licensing (e.g. DB)
Higher operational complexity
Possibly higher HW cost, but lower SW cost instead
Mainly well established vendors
Hyper-converged Less usable for general purposes
Virtualization is quasi a must
SW dependence (related to virtualization SW)
Commercial restrictions (e.g. DB licensing)
Lower operational complexity
Possibly higher SW cost, but lower HW cost instead
Established vendors and newcomers

Both approaches provide unique advantages. Good reasons for coexistence.

Classical or hyper-converged?
Workloads need scale-out / scale-up?
Compute & storage needs scale in tandem?
Workloads require a fixed amount of resources
Granular expansion on component level?
Workloads benefit from data services?
Benefit from unified management?
Existing staff roles?
Utilize existing storage?
Repurposing
Monolithic app?
Mixed operation (multi-hypervisor / physical)?
Optimal support by physical platform?
CAPEX and OPEX
Use cases matter. Business requirements determine the optimum approach.
Recommendation: Decide per each use case; Go for hyper-converged, if benefits outweigh drawbacks.

Summary
HCIs can accelerate the way to the SDDC but are not necessary less costly
Integrated systems can heavily decrease implementation time and risk
The new software-defined, “Fast IT” will emerge alongside the traditional, “Robust IT” resulting in a bimodal IT
The SDDC impacts server, storage and network architectures
Main drivers for SDDC are needs for fast provisioning/scalability
Neither hardware or software defines your data center, it is defined by your business
