High Performance - Hitachi G1500 Hardware Manual

The latest 2.5-inch and 3.5-inch 6 Gbps SAS drives support lower power consumption
■
and higher density per rack with up to 2,304 drives in six 19-inch standard racks. For
more information about drive specifications, see
page 131)
Reference Guide.
Hitachi NAS Platform hardware-accelerated network protocols support up to 2 Gbps
■
throughput for sequential workloads and up to 1.2 million NFS operations per
second.
Efficient caching makes up to 2 TB global cache dynamically accessible by all
■
connected hosts and Hitachi NAS Platform nodes.
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. See the detailed description of this feature and the cable
diagrams in
Expandable cache memory (up to 2 TB per 2-controller system).

Nondisruptive migration is available as a service from Hitachi Vantara 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
Vantara 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 Vantara 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.
