Hitachi G1500 - Scalability

■
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.
■
Deduplication functionality deletes the duplicated data while keeping the data in a
single location when the same data is written to dierent addresses within the same
pool.
■
Disk drives operating at 7,200, 10,000, or 15,000 RPM.
Scalability
The storage systems oer
an entirely new type of scalable and adaptable integrated
active-active architecture that supports integrated management. Hitachi storage systems
can be congured 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 congurations.

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.
