Introducing the Symmetrix DMX-3
The field-proven Direct Matrix Architecture
®
(“Symmetrix DMX-3
architecture” on page 53) provides dedicated, nonblocking
interconnects between I/O directors and global memory regions.
Combined with expanded global memory director technology and
the dynamically optimized caching algorithms of the Enginuity
™
storage operating environment, systems based on the Symmetrix
DMX architecture deliver scalable performance to meet the most
demanding information access, protection, and distribution
requirements.
Symmetrix DMX-3
configurations
The DMX-3 consists of a single system bay and from one to eight
storage bays. The system bay contains the 24-slot card cage, service
processor, power modules, and battery backup unit (BBU)
assemblies. The storage bays contain disk drives and associated BBU
modules. In a highly scalable component and cabinet configuration,
the DMX-3 has the capacity, connectivity, and throughput to handle a
wide range of high-end storage applications.
Figure 1 on page 27 provides a front view of the exterior of a
Symmetrix DMX-3 configured with one system bay and eight storage
bays. Figure 2 on page 28 provides a front view of the exterior of a
Symmetrix DMX-3 configured with one system bay and four storage
bays. Figure 3 on page 28 provides a front view of the exterior of a
Symmetrix DMX-3 configured with one system bay and one storage
bay.
Chapter 2, “Symmetrix DMX-3 Hardware,” provides more complete
descriptions of the Symmetrix DMX-3.
