The Pendulum Swings Back –
Understanding Converged and Hyperconverged
Environments Tony Pearson
Master Inventor and Senior IT Architect
IBM Corporation

Abstract
In the early days of IT,
storage was internal to its
server, over time, storage
outgrew its container, and
we started have externally
attached storage, and
benefits like RAID and
clustered servers for high
availability. Then, SANs,
LANs and WANs took the
main stage, allowing for
greater connectivity and
distance.
But now, it seems the
pendulum is swinging back
with converged and
hyperconverged systems.
This session will provide the
motivations, advantages
and disadvantages of these
new configurations.

The Pendulum Swings on Infrastructure Design
Internal Storage
• Personal
Information
Managers (PIM)
• Mainframe
• AS/400
Advantages
Simple, self-contained
Disadvantages
• Scalability limited to what can fit
inside the hardware container
• Single Point of Failure (SPOF)
(unless you keep 2 or more copies
of data across independent
systems)
• Backups, Security and other Policy
enforcement is done on a system-
by-system basis individually

5
The Pendulum Swings to External Storage
External Storage
• Mainframe
• AS/400
• Linux, UNIX,
Windows
Advantages
More room for storage growth
Two or more servers can directly
attach to external storage
High-availability clusters
Centralize features, snapshots and
tape drives for backups
RAID and Shared Cache for data protection
and performance
Separate depreciation schedules
Disadvantages
• Scalability limited to number of
hosts attached
• Limited distance for external cables

6
The Pendulum Swings to Networked Storage
SAN
LAN
Advantages
Many more hosts can be attached
Greater distances enables Disaster
Recovery
Fewer, larger systems like Tape
Libraries easier to manage
Disadvantages
• SANs and LANs requires different
skill sets
• OS-specific and device-specific
management tools
Networked Storage
• SAN and NAS attached
flash, disk and tape systems
• IBM Spectrum Storage

The Pendulum Swings to Converged Systems
SAN
LAN
Advantages
• Converged Systems can also
connect to existing SAN/LAN
• General purpose or workload-
specific
• Fewer servers required with
virtualization
• Portability to Cloud
Disadvantages
• Lose some of the gains from
SAN/LAN
• Backup and Disaster Recovery?
• Islands of processing and data?
Converged Systems
• Best-of-breed Switches,
Servers and Storage
hardware packaged into a
single rack

451 Research on Hyperconverged Infrastructure (HCI)
451 Research polled 100 enterprise companies
that evaluated Hyperconverged Infrastructure:
• 44% chose not to adopt for enterprise use
• 55% substantial refresh or upgrade of their
datacenter network.
• 78% were looking at eight or fewer nodes.
• 65% prefer Fibre Channel protocol.
• Half of those who chose to integrate HCI in
production expressed dissatisfaction with
system capabilities.
• No large HCI enterprise installations available
for reference.
• Most HCI vendors do not allow the publication
of independent, third-party evaluations of their
performance and scalability claims.
• HCI modules are not interchangeable, long-
term commitment to a single vendor for both
hardware and software.

Performance is based on measurements and projections using standard IBM benchmarks in a controlled environment. The actual throughput or performance that any user will
experience will vary depending upon considerations such as the amount of multiprogramming in the user's job stream, the I/O configuration, the storage configuration, and the
workload processed. Therefore, no assurance can be given that an individual user will achieve throughput or performance improvements equivalent to the ratios stated here.
Prices are suggested U.S. list prices and are subject to change without notice. Starting price may not include a hard drive, operating system or other features. Contact your IBM
