The CPU to HDD Performance Gap
CPU improves 100 times every decade – disk speed hasn’t

CPU continue to improve
MOORE’S LAW:

100X performance remains flat.

As a result, applications
per will suffer more and more

Examples of IO Skew
Driven by Data Growth and Business Models

Very Growth: 60% Std. Growth: 50%
High Days Hot: 10 Days Hot: 60

Skew 1% of data = 80% of IO Skew 5.5% of data = 80% of IO

High Growth: 100%
Days Hot: 30
Low Growth: 50%
Days Hot: 90
Skew 4.2% of data = 80% of IO Skew 8.2% of data = 80% of IO


How Much FLASH?
Used dynamically with FAST

Size of FLASH FIFO • Data follows a predictable
decay in activity
Amount of Data being
created daily • Older data is constantly
being replaced by new
highly active data
• The amount of FLASH
FLASH Capacity required is determined by:
– The amount of data created
each day, and
Number of Days of – The period of time it takes
High Data Activity to cool


Modeling “Data Decay”
A simple GB-Day state model describes typical data behavior

P = (1-C) A, and
Probability of data access

A = LOG1-C (P)
Where:
P is Probability of data access
C is daily Cooling rate
A is data Age in days

Hot

1GB data age in days

• The basic storage pool distribution model
assumes FLASH as the first line of defense
20%
for 80% of all IOs

• As an additional performance buffer, 15K
FLASH Tier

drives are used for overflow for 19% of all
IOs

• Only a 1% chance remains that any IOs will
be serviced from slow 2TB drives

FLASH Percentage
A function of data growth and service level

• Relative more FLASH
is needed when:
– Service level (FLASH
hit rate) is elected
high, and
FLASH portion

– Data growth is high
• More than 25%
FLASH is highly
unlikely!

Data Growth Rate


Getting the Right Blend of Flash
3 fundamental business questions

• How much data is under
management today?
 30 TBs

• How much is your data
growing each year?
 50% YoY

• How long does your data
stay hot?
 60 days


Calculating Net New Data
Net new is a function of amount of starting data and growth

50% Growth Rate • 50% of 30TB is 15TB

15 • The average amount of data
generated each day:
– 15 X 1024 GB / 365 =
42 GB per day

30 30

Start Year 1


Calculating Needed FLASH
FLASH only needs to be large enough to hold hot data

FLASH portion • FLASH capacity:
2.5 – 60 days X 42 GB =
Needed FLASH
2,520 GB
12.5
• FLASH Percentage:
– FLASH Capacity/Total
Capacity
30 30 – 2,520 GB/(45 X 1024) GB X
100 =
5.4%
Start Year 1


Calculating How Much FLASH
FLASH Yearly Growth Rate% X Number of Hot Days X 100
FLASH % =
Portion 365 X (Yearly Growth Rate% + 100%)

Using the Business Data to Configure
With no trace data, the model is used

• The SSD tier retains
a 80% probability of
SSD data re-use
• An 15K HDD tier is
3-Tier used as overflow
with a 19% chance
60 178 FLASH 1st of data re-use
Hot

• Finally, the NL-HDD
days days
Strategy tier is used for long
term online storage
with a 1% chance
and lower of data re-
use
