IBM Systems Magazine, Power Systems - June 2015 - 26

IBM offers two new options
for in-memory databases on
Power Systems servers. DB2* with
BLU Acceleration-Power* Edition
now enables a POWER8 server
running the Linux* on Power in
little endian format to function
as a data mart side-by-side with
legacy x86 data warehouses and
applications. Meanwhile, SAP
is releasing SAP HANA on IBM
Power Systems to allow SAP users
to apply the speed, resiliency
and rock-solid security of the
Power Systems platform to the
application they know and love.
"The multithreading design
of the POWER8 processor is a
massive differentiator against
the equivalent x86 machine,"
says Arthur Fontaine, offering
manager for SAP HANA on Power,
IBM Systems. "And in-memory
databases are especially hungry
for threads."

New for DB2 With BLU
Relational databases like DB2
organize data in rows and
columns, similar to a spreadsheet.
A retailer wanting to track sales
performance at a granular
level might list its retail outlets
in rows and the months in
columns. Traditionally, these
systems read out data row by
row. This approach works well
for transaction processing and
analysis comparing row-based
metrics like the performance of
each store month over month.
Business analytics typically
requires a different approach. In
this case, the goal is to uncover
and quantify interrelationships
and macro trends across the
business. In our retail example,
an analyst might want to assess
performance across all different
distribution channels for the
months of August and December
to compare the results of a
back-to-school promotion to a
holiday sale. With a database

"If you're only able to ask
one question every 20
hours, then you're getting
answers to maybe five
questions over the course
of a workweek."
-Michael Tabron, Power Systems

accessed by rows, the software
would need to load 12 months
of data for each store before
winnowing down to the August
and December numbers. As a
result, what should be a simple
request would get bogged down
by potentially millions or even
billions of irrelevant and timewasting operations.
DB2 with BLU Acceleration
stores and accesses data in
columnar format. Instead of
reading a whole row to access a
column, the processor can access
the column directly in a flash.
BLU Acceleration uses other
techniques to speed processing. It
starts with actionable compression
capabilities that can reduce data
volumes by up to 10 times while
allowing the data to be accessed
without decompression. Dataskipping algorithms instruct
the system to ignore locations
storing data irrelevant to the
query; for example, entries
for software sales when the
focus is on hardware. Finally,
the massive multithreading
capability of the POWER8

processor enables it to run a
single instruction against multiple
pieces of data simultaneously, for
lightning-fast analysis.
In laboratory tests against a
high-performance x86 server
running a row-based database, a
POWER8 processor-based system
using DB2 with BLU Acceleration
performed analytics 82 times
faster. If we follow the numbers,
that means that a report that
normally takes 20 hours to run
would finish in about 15 minutes,
which completely changes the
analytics landscape. "If you're only
able to ask one question every 20
hours, then you're getting answers
to maybe five questions over the
course of a workweek," Tabron
says. "Reduce that to 15 minutes
and you're able to run 32 queries
a day, which means that you can
be a lot more productive with the
exploratory analytics."
In real customer environments,
even better results are possible.

our analysts who gave up on
something he was executing
