The Components of a Traditional Datacenter
(“Three Tier” Infrastructure)

– Enabled the Era of Virtualization
– À La Carte Approach – Allows for either:
• Best of Breed Components
– Great for startup companies
• Cheapest Solutions
– Easy to Scale Each Component
• Compute, Memory, Storage
– Comfortable model for most IT shops

– Typically a “rip and replace” model;
expensive tech refreshes
– CapEx is falling out of favor with C-levels
– Long implementation timelines
– Not much integration
– Lack of scalability
– Requires a lot of specialized IT skills

Converged & Hyper-Converged Infrastructure
(CI & HCI)
7

Converged infrastructure (CI) is an approach to data center
management that seeks to minimize compatibility issues
between servers, storage systems and network devices while
also reducing costs for cabling, cooling, power and floor space.
Convergence attempts to reduce the complexity of modern
datacenters.
What is Converged Infrastructure?

Network
Compute &
Memory
Shared Storage
Converged Infrastructure (CI)
Multiple vendors working together to provide a solution that is
guaranteed to be inter-operable and easily supported.
• Certified/Validated Architecture/Design
• Examples:
• vBlock (VCE; Cisco and EMC)
• SmartStack (Cisco and Nimble)
• FlexPod (Cisco and NetApp)
• FlashStack (Cisco and Pure)
• VersaStack (Cisco and IBM)
• Hitachi UCP Select (Cisco and Hitachi)
• Blueprints (Dell)
• More and more you see many of these components in a single
chassis
• Some folks try to peg CI has a hardware-focused “building block”
approach

– One group handles:
• Engineering – Architectural standards
• Manufacturing – Delivered from factory “ready to run”
• Management – Simplified operations
• Support – expertise over entire system
• Sustaining – Lifecycle assurance with documented standards
– Burned in at the factory
– Dramatically helps “time to first VM”, reduces implementation
headaches and “gotchas”
– Software/Firmware patched in bundles (simpler upgrades)
– Allows for a customer to use preferred storage array
Pros of Converged Infrastructure

Hyper-Converged infrastructure (HCI) is a type
of infrastructure system with a software-centric architecture
that aims to tightly integrate compute, storage, networking,
virtualization resources, and other technologies from scratch in
a commodity hardware box supported by a single vendor.
What is Hyper-Converged Infrastructure?

Hyper-Converged Infrastructure (HCI)
Software-centric architecture that tightly integrates
compute, storage, virtualization and (sometimes) networking
resources and other technologies from scratch in a
commodity hardware box supported by a single vendor.
• Examples:
• Nutanix
• VMware VSAN
• VxRail (Dell EMC)
• Simplivity (HPE)
• ScaleIO (Dell EMC)
• HyperFlex (Cisco UCS and OEM SpringPath)
*Networking is typically not included.

– Also helps “time to first VM”, faster deployment
– Scale more cost effectively, with predictable building blocks
– Single “throat to choke”
• One vender/VAR makes life easier!
• Single support contract
– Promise of simplified management (reduced set of GUI’s)
• Per-VM policy-based management
– Full stack visibility (performance monitoring, logs, analytics)
– Lifecycle assurance
• Vendor ensures all FW is inter-compatible before releasing patches
– Updated in “bundles”, often orchestrated… Automation, Automation, Automation!

Challenges of CI & HCI

• Vendor Lock-in
– Less competition = Less discount
• Too Integrated?
– Issues w/ non linear growth
– Potentially less flexible
• Reliance on Network
– Parity/Redundancy/Rebalancing
– East/West traffic
• Lifecycle Assurance = Waiting For
Updates
Converged Infrastructure Challenges
• Interdependence Between Nodes
– Hot Spots Data Locality
– Troubleshooting
• New Operational Issues w/ Storage
– Node down = Storage down
• Hardware/Software TCO
– Scale-out Model = Higher TCO
• Platform Maturity
• Integrated Data Protection
• NVMe & XPoint is messing things up!

Modern servers are starting to include
features that make them more storage
controllers.
• Bootable Operating System Cards
• Non-volatile Memory – Intel Optane*
– <10µs latency
– 500,000 IOPS
• High-speed/Low-latency NICs
*3D XPoint memory instead of NAND flash
Hardware is Catching Up!
Faster networks will become more
mainstream.
• NVMe-oF* – NVMe over Fabrics
– RDMA
• InfinBand, RoCE, iWARP
– Fibre Channel (FC-NVMe)
*Provide distance connectivity to NVMe
with no more than 10 microseconds (µs)
of additional latency over a native NVMe
device inside a server.

What is RedFish?
It is the first open effort toward building a single API
for all hardware. It replaces IPMI-over-LAN and is a
modern, scalable, secure management API.
DMTF (Distributed Management Task Force)
continues to expand Redfish to cover customer use
cases and technology, like the newer Composition
Service that provides support for binding resources
together into logical constructs.
Redfish is a foundational component of Rack Scale
Architecture (RSA).
What does
Redfish deliver?
• A management API built for
client applications and
browser-based GUIs
• Schema-backed and human-
readable output
• A way to address popular use
cases and customer
requirements
• An approach that meets OCP
Remote Machine
Management requirements.
