Definição de Storage Efficiency

Wikipedia:• “Ability to store and manage data that consumes the least amount of space with little to

no impact on performance resulting in a lower total operational cost”.− Managing costs− Reducing complexity− Limiting risk

Storage Industry Networking Association (SNIA) formula:

Deduplication,

Thin Provisioning,

Snapshots,

Compression

Stop storing so much ! – Why and what is RtCA ?

IBM Real Time Compression Appliance makes your NAS storage more Efficient

Shrinks primary/production active data up to 80% without degrading performance

Shrinks archived and backup data

Supports primary/production data, unlike other storage compression solutions

Can Improve performance of I/O-bound applications

Helps keep more data online for improved analytics and decision making

Reduces backup and disaster recovery time and operation expenses

No Performance Degradation – How? Real-time Compression!Move, Cache and Store Less!

• Compresses data on initial write• Less data stored on primary storage (up to 80%) • Much smaller I/O lower disk workload

• Compresses data before it gets to the storage array

• Larger effective storage cache (up to 80%) • Array can serve more requests from its read / write cache• Lower storage CPU overhead

• Does not cause performance degradation

• Reads/Writes are faster due to storage array’s response from cache instead of disk

• Additionally reads may come from appliance advanced read ahead cache (no write cache)

ESG Lab – Technical Validation Report

In laboratory testing where ProtecTIER backed up data compressed with Real-time Compression, users saw:

82% savings on initial storage 96% overall data reduction when combined with

deduplication 71% reduction in backup time Lower CPU utilization on the deduplication engine Lower disk activity on the deduplication subsystem Less backup network traffic

Orion (Oracle I/O Calibration Tool)

is a standalone tool for calibrating the I/O

performance for storage systems that are

intended to be used for Oracle databases.

The calibration results are useful for

understanding the performance capabilities of a

storage system, either to uncover issues that

would impact the performance of an Oracle

database or to size a new database installation

IBM System Storage


Comprestimator Tool overview

What is it?• Comprestimator is a host based utility for a fast estimation of a block device

compression ratioWhat does it do?

• Estimates compression ratios of data on block devices• Estimates:

− Portion of non-zero blocks in a volume− Compression ratio of non-zero blocks

• Guaranteed compression ration estimation: ~5% Max errorHow does it do it?

• FAST! < 60 sec no matter what volume size• Random sampling throughout a volume• Collects enough non-zero blocks to give compression ration w/ confidence

− The more zero blocks you have, the slower it will run

• Mathematical analysis yields confidence in our guarantee

Compression approaches are not all created equally…

“Today, [EMC] compression is still a post-process on primary

storage …”

Chad Sakac, EMC, blog post 7/11/11

“… users can be confident of using NetApp Compression on

low I/O volumes that have users who can tolerate higher

response times”

“NetApp adds Compression to its Storage Efficiency Portfolio”, Wikibon, January, 2011

“Our research shows that in-line compression solutions such

as those offered by IBM Real-time Compression are orders of

magnitude more efficient and ultimately more effective for

primary storage than alternatives that cannot operate in real-

time.”David Vellante, Chief Research Advocate, Wikibon, May, 2012
