For the most up-to-date regulatory document for your product line, go to the Technical Documentation and Advisories section on EMC Powerlink. All other trademarks used herein are the property of their respective owners. This EMC product has more than one power supply cord. To reduce the risk of electric shock, disconnect all power supply cords before servicing.

Ground circuit continuity is vital for safe operation of the machine. Never operate the machine with grounding conductors disconnected. Remember to reconnect any grounding conductors removed for or during any installation procedure. Cet appareil Rmc comporte plus d’un cordon d’alimentation. Additional warnings and cautions Before attempting to service EMC hardware described in this document, observe the following additional Warnings and Cautions: WARNING The hardware enclosure contains no user-serviceable parts, dm-x4 it should not be moved or opened for any reason by untrained persons.

If the hardware needs to be relocated or repaired, only qualified personnel familiar with safety procedures for electrical equipment and EMC hardware should access components inside the system or gide the system.

To protect against physical harm, power off the system whenever possible while servicing. Remove rings, watches, or other jewelry and neckties before you begin any procedures. Use caution near any moving part and any part symetrix may start unexpectedly such as fans, motors, solenoids, etc. Always use the correct tools for the job.

Always use the correct replacement parts. Keep all paperwork, including incident reports, up-to-date, complete, and accurate. These chips are very susceptible to damage caused by static discharge and need to be handled accordingly. Store all gkide circuit boards in antistatic bags.

Use a ground strap whenever you handle a printed circuit board. Summetrix specifically designed for nondisruptive replacement, never plug or unplug printed circuit boards with the power on. Severe component damage may result. Therefore, some functions described in this guide may not be supported by all versions of Symmetrix hardware or Enginuity currently in use. If produch Symmetrix DMX-4 does not function properly or does not function as described in this document, please contact your EMC representative.

Please send your opinion of this guide to: The DMX-4 model establishes a new performance and capacity trajectory for the highest of the high-end enterprise systems. The point-to-point Fibre Channel backend has advanced disk isolation capabilities to improve serviceability. The DMX-4 fully leverages the EMC industry-leading storage management functionality and introduces the economic benefits of scalable packaging to the high-end storage market.

Table 1 on page 26 describes some of the Symmetrix DMX-4 performance features. Combined with expanded global memory director technology and the dynamically optimized caching algorithms of the Enginuity storage operating environment, systems pgoduct on the Symmetrix DMX architecture deliver scalable performance to meet the prkduct demanding information access, protection, and distribution requirements.

Symetrix system bay contains the slot card cage, service processor, power modules, and battery backup unit BBU assemblies. The storage bays contain disk drives and giide BBU modules. In a highly scalable component and cabinet configuration, the DMX-4 has the capacity, connectivity, and throughput to handle a wide range of high-end storage produt.

Figure 1 on page 27 provides a front view of the exterior of a Symmetrix DMX-4 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-4 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-4 configured with one system bay and one storage bay. Enginuity manages and ensures the optimal flow and integrity of information through the different hardware components of the Symmetrix system. Enginuity manages all Symmetrix operations from monitoring and optimizing internal data flow, to ensuring the fastest response to the user’s requests for information, to protecting and replicating data.

Symmetrix platform and Enginuity operating environment Ensures system availability through advanced fault monitoring, detection, and correction capabilities and provides concurrent maintenance and serviceability features.

Interrupts and prioritizes tasks from ;roduct and, for example, ensures that fencing off failed areas takes precedence over other operations. Offers the foundation for specific software features available through EMC s disaster recovery, business continuance, symmetrxi storage management software.

Provides functional services for both Symmetrix-based functionality and for a large suite of EMC storage application software. Provides uniform access through APIs for internal calls and provides an external interface to allow integration with other software providers and ISVs. They enable the creation of storage management applications that don t have to understand the management details of each symmerrix within the total storage environment.


The capacities are based on storage capacity of each disk guied type and the following storage protection options: Factors affecting storage capacity The following factors affect disk storage capacity: Type of data protection options used. These volumes are protected using mirroring, consuming slightly less than 24 GB total physical space. The size of the blocks or bytes per block.

Vault devices Symmetrix DMX-4 uses vault devices for vaulting data from global memory during a power-down operation. Vault devices require 5 GB of space. For each pair of disk directors in a DMX-4, GB of total capacity is reserved for symmterix data from memory during system powerdown.

Configuration rules for vault devices on page 70 and Vaulting on page contain additional information. Storage capacities and global memory requirements The total global memory requirement for a Symmetrix DMX-4 is based upon specific system configurations and customer requirements. Besides the customer s applications, other variables that affect the amount of global memory a Symmetrix DMX-4 requires include the following: Number of global memory directors Variable back-end disk director and front-end channel director board configurations Various loop configurations for disk drives Number of disk drives Disk capacity, including speed and protection type Number of logical volumes Your local EMC Sales Representative will assist you in determining your global memory requirements.

Global memory directors on page 84 provides additional information on memory configurations. Table 2 on page 33 identifies many of the Symmetrix DMX-4 and Enginuity supported features that enhance performance and increase throughput.

Table 3 on page 35 highlights many of the Symmetrix DMX-4 availability and integrity features. The service processor communicates with the EMC Customer Support Center through a customer-supplied direct phone line. The service processor automatically dials the Customer Support Center whenever the Symmetrix system detects a component failure or environmental violation. An EMC Product Support Engineer at the Customer Support Center can also run diagnostics remotely through the service processor to determine the source of a problem and potentially resolve it before the problem becomes critical.

The XCM provides the low-level system-wide communications for running application software, monitoring, and system diagnostics from the service processor. Symmetrix DMX systems feature an incrementally scalable design with a low parts count for quick component replacement, should a failure occur. This low parts count minimizes the number of failure points.

The Symmetrix DMX systems feature nondisruptive replacement of its major components, which can be replaced while the Symmetrix system is powered on, including: Keyboard Video Display and Mouse Note: Chapter 2, Symmetrix DMX-4 Hardware, and Nondisruptive component replacement on page provide more information on these components.
