Hitachi Data Mobility

Automated and Simplified Storage Tiering

Hitachi Data Mobility
  • Automates optimized use of tiered storage infrastructure.
  • New Dynamic Tiering active flash1 maximizes performance by moving suddenly active data to higher performing tiers in real time.
  • Access newer, more powerful features, and retire older, underperforming storage via online data migration.
Overview

Optimize Data Placement and Performance

Hitachi Data Mobility provides complete data movement capabilities, combining Hitachi Dynamic Tiering and Hitachi Tiered Storage Manager software. This duo improves performance and drives intelligent data placement, nondisruptive volume migrations, and optimization within Hitachi virtualized storage environments.

Dynamic Tiering software maximizes performance, simplifies data life-cycle management, and optimizes use of tiered storage.

  • Automates data placement for higher-performance and lower costs.
  • Active flash2 proactively preserves flash endurance.
  • Delivers self-optimized performance and space efficiency.
  • Enables automatic wide-striping performance optimization.

Tiered Storage Manager lets you proactively match business application price, performance and availability characteristics to storage resource attributes.

  • Easily define storage tiers based on data usage and performance demands.
  • No complex analysis expertise is required.
  • Manage across all data types, Hitachi storage platforms, and compatible third-party storage.

Complement Automated Storage Tiering With Flash Storage

Features and Benefits

Features

Improves Performance

  • Delivers near Tier-0 performance at a lower cost by coupling flash and SAS storage.
  • Automatically moves the most active data to the highest-performing tier.
  • Active flash3 moves fine-grained pages to higher performing tiers in seconds to subseconds.
  • Supports highest efficiency and throughput through granular, page-based data movement.
  • Employs wide striping across entire storage pools.
  • Optimizes data placement automatically for performance using an I/O rate-based heat index.

Reduces Storage Costs

  • Lowers media costs through self-optimized use of storage tiers.
  • Achieves space efficiency through thin provisioning.
  • Eliminates manual data classification efforts.
  • Decreases space, power and cooling requirements.

Increases Administrative Efficiency

  • Automatically puts the right data in the right place at the right time.
  • Adjusts to dynamic workloads and capacity requirements.
  • Moves pages up and down for optimal placement over time, according to their heat index.
  • User-defined storage tiers based on application needs.
  • Nondisruptive volume migration across storage tiers.
  • Data placement profiles save user-defined settings as reusable templates.

3 Some features may be available after initial release.

Benefits

  • Improves workload responsiveness by moving suddenly active data to flash tiers fast.
  • Optimize data placement by application service-level requirements.
  • Lower costs by moving infrequently used data to economical storage tiers.
  • Quickly provision storage for new applications.
  • Streamline technology and system refreshes with nondisruptive data migrations.
  • Significantly reduce administration time and improve results.
