Performance
Gap
CPU performance up 10x this last decade
Storage has grown capacity but unable to keep up
in performance
Systems are now Latency & IO bound resulting in
significant performance gap
From 1980 to 2010, CPU performance has grown 60% per year*
…and yet, disk performance has grown ~5% per year during that same period**

Enabling the use of
Flash in the Enterprise

4. A significant portion of IBM’s strategic billion $ investment in
FlashSystem has been dedicated to overcome these issues
But …
IBM FlashCore Technology: Overcomes Tough Obstacles
• Less and less electrons on the floating gate
• More and more cell to cell interference
• Data retention harder
• Bit error rate increases
• Common solutions to correct errors
often result in more latency!
Density increasing and cost decreasing
AND really, really fast!

5. IBM MicroLatency™ Module Key Differentiators
Innovative ECC algorithm corrects very high bit error rates (does
not require additional reads)
Health binning and heat segregation
FlashCore technology continually assesses
health by monitoring several key parameters
Hotter data placed in healthier blocks –
Up to 57% improvement in endurance!
Write Amplification reduced by up to
45% by grouping like heat levels
The IBM and Micron collaboration provides special access to the
Flash
Extensive characterization determined optimal
read offsets to set as block ages
Powerful checks on entire data path, including inside
the flash modules
Variable Stripe RAID reduces what needs to be retired
Results:
Large endurance gains w/o latency penalty
Asymmetrical wear leveling results in higher
endurance in real life workloads!
As the part ages and we determine the health of
each block, the ideal voltage levels are
set in order to minimize errors!
Outstanding data reliability
and improved endurance

6. Form Factor SSD
• Flash failure = Disk failure
• Requires top-level RAID
• Relatively frequent hot-swaps
Enterprise Flash Drive or Memory Module
• Flash failure = Degraded state within module
• Performance impact on RAID set
• Hot-swap to resolve
FlashSystem with Variable Stripe RAID
• Preserves Flash life
• Preserves performance
• Re-parity data in microseconds

No Parity
Less maintenance touches while
still preserving the life,
protection, and performance of
the Day-1 experience

Pattern Removal is a special case of deduplication. We essentially take
the hash of the data and compare that to the hash of known patterns. If
a match is found, we can use that hash to reference the data.
