Scalability
The storage system offers an entirely new type of scalable and adaptable
integrated active-active architecture that supports integrated management.
Hitachi Data Systems 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.

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 one or
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 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 system can be configured up to 65,280 logical volumes.
○
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.
