Automate Storage Tiering
Automate storage tiering and improve performance

  • Automates optimized use of tiered storage infrastructure
  • Automatically moves fine-grain pages to position data according to workload, maximize storage service levels and minimize storage costs
  • Provides all the wide striping performance, simplified administration and storage capacity savings benefits of Dynamic Provisioning
Overview

Simplify Tiered Storage, Optimize Performance

Hitachi Dynamic Tiering software simplifies storage administration, solves the complexities of implementing data lifecycle management and optimizes the use of tiered storage. It eliminates the need for time consuming manual data classification and data movement to significantly improve tiered storage efficiencies. Using Hitachi Dynamic Provisioning, Hitachi Dynamic Tiering inherits the advantages of simplified provisioning, capital savings and self-optimizing performance. Hitachi Dynamic Tiering automatically moves fine-grain data within these tiers, according to workload, to the most appropriate media. This maximizes service levels and enables customers to minimize total costs of storage.

  • Automates data placement for higher performance and lower costs
  • Manages multiple storage tiers as single entity
  • Supports 1, 2, 3 tiers of storage per pool
  • Delivers self-optimized performance and space efficiency
  • Enables automatic wide striping performance optimization

Features and Benefits

Reduces Storage Costs

  • Reduces media costs through self-optimized use of storage tiers
  • Achieves space efficiency through thin provisioning
  • Decreases drive counts
  • Eliminates manual data classification
  • Eliminates manual data movement between tiers
  • Reduces operational overhead
  • Decreases space, power and cooling requirements

Improves Performance

  • Delivers near Tier 0 performance at a lower cost by coupling SSD and SAS storage
  • Scales with SAT, SAS boosts performance
  • Employs wide striping across entire pool
  • Optimizes data placement automatically for performance using an I/O rate-based heat index
  • Supports highest efficiency and throughput through granular page-based data movement

Increases Administrative Efficiency

  • Simplifies management of up to 3 storage tiers as a single volume
  • Automatically places fastest drives in highest tier and slower drives in lower tiers, as appropriate
  • Automatically moves most active data to highest performing tier
  • Adjusts to dynamic workloads and capacity requirements
  • Moves pages up and down for optimal placement over time according to their heat index
  • Automatically puts the right data in the right place at the right time
  • Provides the convenience of thin provisioning allocations and simplified capacity management
  • Significantly reduces administration time and improves results
