High Performance - Hitachi Virtual Storage Platform G1000 Hardware Manual

• The HNAS file module provides primary data deduplication using hardware-
based SHA-256 calculation engines. This module achieves up to 90%
capacity savings while maintaining high performance.
• When each controller is housed in a separate rack, the two controller racks
can be placed up to 100 meters apart. In addition, the drive racks
attached to a controller rack can be placed up to 100 meters from the
controller rack. This enables maximum flexibility to optimize data center
space usage and provides ease of access for operation and maintenance.

cable connections on page
• Expandable cache memory (up to 2 TB per 2-controller system).
• Nondisruptive migration is available as a service from Hitachi Data
Systems representatives as well as by purchasing an optional software
license for customer implementation. Best practice is to use the
nondisruptive migration planning service offered by Hitachi Data Systems
Global Solution Services (GSS). See

• High temperature mode is a licensed feature that allows the storage
system to operate at either standard temperature (60.8°F to 89.6°F /
16°C to 32°C) or higher temperatures (60.8°F to 104°F / 16°C to 40°C) in
a data center, saving energy and cooling costs. See

High performance

Hitachi Data Systems offers the highest performance storage systems for the
enterprise-class segment. The high-performance storage system enables
consolidation and real-time applications, a wide range of storage and data
services, software, logical partitioning, along with simplified and unified data
replication across heterogeneous storage systems. Its large-scale, enterprise
class virtualization layer, combined with Hitachi Dynamic Tiering and thin
provisioning software, allows you to consolidate internal and external storage
into one pool.
The storage system includes several features that improve system
performance:
• Hitachi Accelerated Flash module drives that support ultra-high I/O rates
and ultra-low latency.
• Solid-state drives with high-speed response.
• Device Manager - Storage Navigator and Hitachi Storage Advisor provide
integrated data and storage management to ensure high-speed data
transfer between the back-end directors and small form-factor (SFF) or
large form-factor (LFF) drives at 6 Gbps using a SAS interface.
• Ability to scale and upgrade system performance.
• Compression functionality reduces the size of stored data by encoding
without reducing the amount of data.
