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 standar
d racks. For

Hitachi NAS Platform har
dware-accelerated network protocols support up to 2 Gbps
throughput for sequential workloads and up to 1.2 million NFS operations per
second.
■
Ecient caching makes up to 2 TB global cache dynamically accessible by all
connected hosts and Hitachi NAS Platform nodes.
■
The HNAS le 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
exibility 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
Long cable connections (on page 112) .

Expandable cache memory (up to 2 TB per 2-contr
oller system).

Nondisruptive migr
ation is available as a service fr
om
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 oered by Hitachi
Vantara Global Solution Services (GSS). See

High temper
atur
e mode
is a licensed featur
e 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 temperature mode (on page 20) .
High performance
Hitachi V
antar
a
oers the highest performance stor
age 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 simplied and unied 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.
