overview
The following describes the hardware components of the VSP G1000, VSP
G1500, and VSP F1500 storage systems.
□System overview
VSP G1000, VSP G1500, and VSP F1500 overview 13
Hitachi Virtual Storage Platform G1000, G1500, and Virtual Storage Platform F1500 Hardware Guide

System overview
The VSP G1000, VSP G1500, and VSP F1500 are high-capacity, high-
performance, unified block and file enterprise storage systems that offer a
wide range of storage and data services, software, logical partitioning, and
unified data replication across heterogeneous storage systems.
Features
The VSP G1000, VSP G1500, and VSP F1500 storage systems include state-
of-the art advances in hardware technology that improve reliability,
serviceability, and accessibility to drives and other components when
maintenance is required.
• VSP F1500 all-flash array is configured exclusively with the latest
generation of flash module drives (FMDs) to provide performance
optimized for intense I/O operations. Designed for flash-first, high-
performance workloads and leveraging Hitachi's SVOS-based deduplication
and compression, VSP F1500 offers up to five times greater ROI with
unified support for SAN, NAS, and mainframe workloads.
○Accelerated flash architecture delivers consistent, low-latency IOPS at
scale.
○Adaptive flash management distributes writes and rebalances load over
time.
○Hitachi FMDs deliver enterprise performance with superior functionality
and greater cost value.
• The VSP G1500 and VSP F1500 are equipped with new virtual storage
directors (VSD). The VSD uses the latest generation of Intel Xenon 2.3-
GHz 8-core microprocessor to efficiently manage the front-end directors,
back-end directors, PCI Express interface, local memory, and
communication between the service processor.
• Hitachi Accelerated Flash FMD DC2 storage offers a patented data-center-
class design and rack-optimized form factor that delivers more than 8 PB
per system. The FMD DC2 supports a sustained performance of 100,000
8K I/O per second, per device, with low and consistent response time.
• 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
Storage system specifications on page 139. For information about Hitachi
racks, refer to the Hitachi Universal V2 Rack 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.
14 VSP G1000, VSP G1500, and VSP F1500 overview
Hitachi Virtual Storage Platform G1000, G1500, and Virtual Storage Platform F1500 Hardware Guide

• 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 Long
cable connections on page 116.
• 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 Nondisruptive service and upgrades
on page 18.
• 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 temperature
mode on page 19.
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.
VSP G1000, VSP G1500, and VSP F1500 overview 15
Hitachi Virtual Storage Platform G1000, G1500, and Virtual Storage Platform F1500 Hardware Guide

• Deduplication functionality deletes the duplicated data while keeping the
data in a single location when the same data is written to different
addresses within the same pool.
• Disk drives operating at 7,200, 10,000, or 15,000 RPM.
Scalability
The storage systems offer an entirely new type of scalable and adaptable
integrated active-active architecture that supports integrated management.
Hitachi storage systems can be configured in numerous ways to meet
performance and storage requirements.
Scalable system performance
System performance can be optimized according to the needs of the user and
can be easily upgraded (in small or large increments) as storage needs
increase. The following table shows the supported configurations.
Table 1 System performance configurations
Number of
controllers
Number of VSD pairs /
CPU cores1
Cache size2
1 min = 1 (16 cores)
max = 4 (64 cores)
min = 64 GB3
max = 1 TB
2 min = 2 (32 cores)
max = 8 (128 cores)
min = 64 GB per system (32 GB per
controller)3
max = 2 TB
Notes:
1. A VSD pair consists of two VSD blades. Each VSD contains one 8-core processor.
2. Cache memory modules can be either 16 GB or 32 GB, but only one memory module size can be
used in a system.
3. HDS minimum cache per system is 64 GB whether the system contains one or two controllers.
Scalable storage capacity
• The minimum configuration is a single rack with one controller chassis in a
diskless configuration.
• A small system can be a single rack with one controller chassis and up to
two drive chassis or flash drive chassis.
• A mid-sized system can be three racks with one controller chassis and a
maximum of eight combined LFF or SFF drive chassis and up to two flash
module drive (FMD) chassis.
• For combined block and file storage systems, the maximum configuration
depends on how many HNAS servers and switches are installed. Consult
your authorized representative for examples of available configurations.
• Maximum storage capacity:
○The storage systems can be configured up to 65,280 logical volumes.
16 VSP G1000, VSP G1500, and VSP F1500 overview
Hitachi Virtual Storage Platform G1000, G1500, and Virtual Storage Platform F1500 Hardware Guide

○Configurable up to 2,304 SFF disk drives with a maximum physical disk
capacity of approximately of 3.9 PB per storage system, or up to 1,152
LFF disk drives with a maximum physical disk capacity of approximately
6.8 PB per storage system.
○A drive intermix configuration can be configured up to 576 flash module
drives with a maximum physical capacity of 8.0 PB per storage system.
Flexible connectivity
The storage system supports connectivity to mainframe hosts through
FICON® front-end directors and to open servers via Fibre Channel, iSCSI, and
Fibre Channel over Ethernet (FCoE) front-end directors. The storage system
can be configured with a combination of all of these front-end directors to
support both mainframe hosts and open servers simultaneously.
For details about host connectivity and OS support, see https://
support.hds.com/en_us/interoperability.html.
High reliability
The storage system includes the following features to enhance reliability:
•Multiple RAID configurations: The system supports RAID 6 (6D+2P and
14D+2P), RAID 5 (3D+1P and 7D+1P), and RAID 1 (2D+2D and 4D+4D).
•Duplicate hardware: Every module in the controller chassis and drive
chassis is configured in redundant pairs so that if any module fails, the
redundant module takes over until the failed component is replaced. The
redundant hardware includes power supplies, VSD pairs, cache path
controllers, front-end directors, back-end directors, and drives. If one of
these hardware components fails, the storage system continues normal
operation with zero data loss.
•Protection from power failures: The storage systems have dual-power
feeds. In the event of a partial power loss on one of the feeds, the system
operates normally on the alternate feed until full power is restored. In the
event of a full power loss, the cache backup modules maintain the
availability of the cache contents for 32 minutes while the system copies
the system configuration information and all data in the cache to a cache
flash drive (SSD).
High flexibility
The storage systems are available in several configurations, from a small
single rack, diskless system to a large six-rack system that includes two
controller chassis, up to 2,304 SFF drives, up to 1,152 LFF drives, up to 384
SSDs, up to 576 flash module drives, and a total of 2 TB cache. The systems
can be easily reconfigured for more storage capacity.
The storage systems support block-only, file-only, and unified (block and file)
configurations in open and mainframe environments. Unified systems contain
Hitachi Network Attached Storage servers and switches in addition to the
block controller and storage drives.

Typical system configurations
The storage systems can be configured to a meet a variety of storage needs,
with the following typical configurations based on customer use-cases:
•Tiered storage: A storage system configured for tiered storage consists
of multiple drive types, including high-performance flash module drives for
fast data access, medium performance and capacity drives for most
storage needs, and maximum capacity drives for data warehousing, all in
one system. A tiered storage system can be configured with FMDs (flash
module drives), SSDs (solid state drives), SAS drives (SFF or LFF), and
high-capacity LFF drives. Software applications such as Dynamic Tiering
allocate data to the appropriate drives based on frequency of access.
•Maximum performance: A storage system configured with only flash
module drives delivers maximum performance. This two-controller system
can contain 12 FMD chassis with a total of 576 FMDs. This system is
designed for an online retail site where customers expect fast access to
multiple images, or a hospital medical imaging system where physicians
need immediate access to 3D CAT or MRI images.
•Maximum storage capacity: A storage system containing 12 LFF chassis
with a total of 1152 LFF drives provides the maximum storage capacity.
This system configuration with less priority for high-speed access is ideally
suited for use as a data warehouse for medical or insurance records.
Software applications
The storage systems provide the foundation for matching application
requirements to different classes of storage and delivering critical services,
including:
• Business continuity services
• Content management services (search, indexing)
• Thin provisioning
• Dynamic Tiering
• High availability
• Security services
• I/O load balancing
• Data classification
• File management services
Nondisruptive service and upgrades
The storage systems are designed specifically to avoid any interruptions
during normal operations while servicing or upgrading the system
components.
• Main components can be “hot-swapped” (added, removed, or replaced
without disruption) during normal operation. These include every module
in the controller chassis and the drive chassis, such as power supplies,
virtual storage directors, front-end directors, and back-end directors,
cache and cache backup modules, SVPs, and drives.

• A service processor (SVP) mounted in the controller chassis monitors the
operating condition of the storage system. Connecting the SVP with a
service center allows authorized service personnel to manage the system
remotely.
• An online, nondisruptive upgrade of the Storage Virtualization Operating
Systems (SVOS) can run during normal operation without shutting down
or restarting the storage system.
• Optional Migration Enablement Service (includes pilot migration) is
available to jump-start self-service migration. For complex, large-scale,
heterogeneous, and remote replication data center environments,
nondisruptive migration service from Hitachi Global Solution Services
(GSS) is required. Contact your HDS authorized sales or service
representative for more information.
High temperature mode
High temperature mode is a feature that allows the storage system to
operate at 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), saving energy and cooling
costs. Temperature sensors at the air inlets in the primary microprocessor
blades measure the ambient air temperature.
High temperature mode window
High temperature mode is set through the Edit High Temperature Mode
window in the Device Manager - Storage Navigator GUI. The window also
displays alerts when the ambient air temperature exceeds the preset limits.
• In standard temperature mode, a temperature alert (SIM) appears when
the temperature in the storage system exceeds 89.6°F / 32°C.
• In high temperature mode, the temperature alert (SIM) appears when the
temperature in the storage system exceeds 104°F / 40°C.
System life
The lifetime of the system is five years when operating in the standard
temperature mode. This lifetime is reduced when operating the system in
high temperature mode, even if you change the system to standard
temperature mode later.
Cache flash memory battery life
When high temperature mode is enabled, the cache flash memory battery life
is reduced to two-thirds of the battery life when high temperature mode is
enabled.
Example 1: A new cache flash memory battery has three years of usable life
when operated in a standard temperature environment. If you enable high
temperature mode when the battery is new, the battery life will be reduced to
two years.

Hitachi Virtual Storage Platform G1000, G1500, and Virtual Storage Platform F1500 Hardware Guide

Example 2: The storage system is used for two years at normal temperature
mode. The cache battery has one year of usable life remaining at that time. If
you enable high temperature mode, the life of the battery is reduced to eight
months.
Cache flash memory battery date
When high temperature mode is enabled, the battery replacement notice
displays one year earlier than when high temperature mode is disabled.
After high temperature mode is enabled, the date of the battery replacement
notice cannot be changed back to normal, even if high temperature mode is
disabled. When high temperature mode is enabled, a confirmation message
appears.
Caution: Important information about using high temperature mode.
See the System Administrator Guide for additional information.
•Notify Technical Support: Before enabling high temperature mode,
contact Hitachi Data Systems Support at https://support.hds.com/en_us/
contact-us.html for updates or additional information besides the following
notes.
•Guidelines for operating with flash module drives in high
temperature mode:
○Do not enable high temperature mode if the system contains flash
module drives (FMDs) from an earlier generation (prior to Hitachi
Accelerated Flash FMD DC2 drives). The early generation FMDs cannot
operate in high temperature mode. Only enable high temperature mode
with Hitachi Accelerated Flash FMD DC2 drives.
○Do not enable high temperature mode if the system contains a
combination of early and current generation FMDs.
•Operating altitude: Because thinner air does not provide sufficient
cooling, do not enable high temperature mode if the system is located
above 4920 ft / 1,500 m above sea level. A storage system can operate up
to 9842 ft / 3,000 m above sea level in standard temperature mode.
•System noise: When the storage system is used in a high temperature
environment near 104°F / 40°C, the fans operate at high speed, increasing
system noise. See Environmental specifications on page 151 for detailed
information.
Temperature measurement
Ambient air temperature is measured by a sensor in the cooling air inlet on
each module in the primary VSD pair on each controller.
