Tiered Storage Basics

4

What Is Tiered Storage?

• Not all data is created equal

• Dynamically match type of data with a storage system

optimized for that data type

• A simple way to start:

– Segregate data into active and inactive data sets

• Active data placed on high-performance storage

• Inactive data placed on low-cost storage

• Dramatic cost benefits

5

History of Tiered Storage

• Historical impediments

– For many years, the opportunity to tier was limited by

the absence of a good choice for the second tier

• Tape too slow and fragile for general purpose Tier 2

– Adding a tier of storage was not transparent to user

and application access to data

• Moving data is disruptive

• What changed?

– Introduction of high-capacity SATA

• Acceptably slower when used to store less active data

– File virtualization

What Is File Virtualization?

• Logical abstraction of file systems

• Decouples access to files from physical location of files

Case Study – Medium Enterprise

• Challenge – rapid data growth:

– High costs for disk capacity

– Long backup times and high costs for backup media

• Solution

– Moved data not modified in last month (90%) to Tier 2

– Different backup policies for Tier 1 and Tier 2

• Benefits

– Disk cost savings

• New disk capacity is all Tier 2 (at 1/5 the cost…)

– Backup cost savings

• Weekly full backups consume 10% tape media

• Weekly full backup times dropped from >36 hours to <3 hours

19

Sample Cost Savings – 25TB Environment

• Hard cost savings

– Use of lower-cost disk storage $270,000

– Reduction in backup costs $50,000

– Increased capacity utilization (40->80%) $536,000

– Power savings $34,000

– Total $890,000

• Soft cost savings

– Transparent cross-vendor/technology capacity expansion

– Transparent cross-vendor/technology migration

– Reduction in backup/restore times

– Reduced backup failures
