Bull’s Remote Support network can be used to upgrade Symmetrix operating software (microcode) on
an operational Symmetrix system with minimal interruption of service. This unique approach upgrades
Symmetrix software and functionality without downtime, combining fast functional enhancements
with continuous data availability.
5.1.5. Information Sharing
Symmetrix provides centralized, sharable information storage that supports changing environments
and mission-critical applications. This leading-edge technology begins with physical devices shared
between heterogeneous operating environments and extends to specialized software that enhances
information sharing between disparate platforms:
•
Symmetrix Enterprise Storage Platform (ESP)
software provides simultaneous mainframe and
open systems support for Symmetrix systems.
•
InfoMover
extends information sharing. InfoMover facilitates high-speed bulk file transfer
between heterogeneous mainframe, UNIX, and Windows NT host platforms without the need for
network resources.
5.1.6. Information Management
Symmetrix systems improve information management by allowing users to consolidate storage
capacity for multiple hosts and servers. Powerful tools are offered and it dramatically simplifies and
enhances Symmetrix configuration, performance, and status information gathering and management:
•
ControlCenter™
is a family of applications that provides extensive user management tools.
ControlCenter’s monitoring, configuration, control, tuning, and planning capabilities simplify
management of the Symmetrix supporting open systems and mainframe environments, while
keeping track of changing requirements
•
PowerPath™ optionally offers a combination of simultaneous multiple path access, workload
balancing, and path failover capabilities between Symmetrix systems and supported server hosts.
•
Volume Logix allows multiple UNIX and NT server hosts to share the same Symmetrix Fibre
Adapter port while providing multiple volume access controls and data protection. The Volume
Logix software also provides volume access management for non-supported Volume Logix GUI
and Host Utilities platforms that are connected via Fibre Channel.
•
Symmetrix Optimizer provides automatic performance tuning for Symmetrix by balancing
performance and eliminating potential bottlenecks. It reduces the effort and expertise required to
achieve optimal Symmetrix performance by automatically balancing I/O activity across physical
drives. RAID-S
is not
supported.
5.2. Symmetrix Product Description
5.2.1. Host Channel Connection
Symmetrix systems provide exceptional host channel connectivity through combinations of Channel
Directors, each with two advanced microprocessors.
Each Channel Director is connected to two memory buses and supplies multiple independent data
paths to cache, then to disk, from the host system. Channel Directors are installed in pairs, providing
