Data and Performance Requirements grow
much faster than Budgets
2012 2017 2022
Your data nearly doubles every 2 years
Your storage budget growths around
5% per year
Mind the
gap!

• What are my pain-points?
• Performance
• Rackspace / Operational cost / Energy
• Where does Flash help me?
• 10% of Data generate 90% of I/Os
• A Flash TB is still x-times more expensive than an HDD TB
• What is the performance guarantee?
• What is a sustainable / expandable entry into Flash?

What should You Consider when You Plan to
change to Flash/SSD Storage?

• How to integrate the
new technology into my
existing environment?
• Which new processes
are necessary to
manage my new
investments?
• Does each application
needs its dedicated
flash-storage?
• How to ensure essential
operational capabilities
like high availability or
transparent failover?
• What tools are available
in regard to data
migration, tiering and
thin provisioning?
Integration and
Management
Typical Challenges with Flash-Integration
Availability of
Functionality
Shared usage of
Flash Storage

• Dedicated insertion of
Flash
• Cost Effective
• Measurable
• Seems to be simple to
integrate
• Does generate (many)
Islands to Manage
• Cost Effective
• Performance
Improvement
• Seems to be difficult to
be Realized
• Does it really help My
most Demanding Apps?
• Seems to ensure best
Performance Results
• Very cost intensive
• No exactly predictable
Performance Advantage
• Entire Migration Needed
The most common ways
to add Flash to Your Application(s)
Isolate Applications
– use Local Flash
Rip and Replace
towards All Flash
Use Hybrid (tiered)
Storage (x% Flash)

• Shared usage of Flash
between server and
application
• Minimized downtimes
and risk at integration
• Simple expansion of
flash at any time
• Real path to all flash
integration options
• Complete set of all
storage services also for
flash
• Auto-Tiering on block-
level

Serial Scheduling DataCore Parallel I/O
Concurrent
tasks
End-to-End Parallelism with Parallel I/O
NVMe takes advantage of parallel, low latency data paths to underlying media, Parallel I/O
takes advantage of multi-cores to remove serial I/O bottlenecks prior to controllers/data paths

Data-Caching and -Tiering
Less active data will be
stored on cost-effective storage
Active data will be
stored on faster storage

Auto-Tiering on Block-level
• Not all Tier-1-Applications have data
which needs the most performant
storage
• DataCore predictable ensures that only
the most challenging data are stored in

• Provider of Cloud Services &
Software for Accounting
• Approx. 1000 employees, own datacenter
• Business Requirements
• Overcome Performance Complains at
peak times, e.g. with VAT declarations
• Plan to grow Cloud Business 4 Times
• Budget Constraints
• Initial Situation (storage)
• 2 x 90TB HDD (Raid 5 each, mirrored) +
2% SSDs as cache
Real Life Example

The Solution
Application Layer
Cloud Services
(unchanged)
Tier 1: 2x DataCore SDS
2x SN260 NVMe (12,8TB)
Tier 2: Classical Flash
2x 2U24 All Flash (SAS SSD,
Raid 5, 184 TB)
Tier 3: Classical HDD
2x Ultrastar Data60 (HDD,
Raid 5, 360 TB)

Compared to previous storage setup, this customer achieved:
• 600% more capacity
• >10 times better Performance
• 10TB rebuild with less than 1hr at bandwidth greater 1.5GB/s
• Measured using GrafANA test platform
• 30-40% lower TCO (over 5 years)
• Compared to continuing (w/o extension!) with the old infrastructure

Customer Benefits Achieved

Summary and Next Steps
19

• All-Flash
• 80 TB Flash
With an assumed HW-Price difference (NVMe Flash vs. SAS HDD)
of $900 per TB, You could save (64 x $900) $57,600!
• Hybrid (20% flash)
• 16 TB NVMe Flash
• 64 TB SAS HDD
Pointed usage of NVMe Flash:
Full Performance, tremendous HW Savings

Various Deployment Options
Traditional
Converged
(Server-SAN)
Hyperconverged Hybrid-Converged
With seamless migration between them during regular business operation!
