EMC has developed a wide range of disaster recovery and business continuity solutions to handle both disasters and planned outages.
The Symmetrix Remote Data Facility (SRDF), run in conjunction with EMC's Symmetric Enterprise Storage System, is a complete business continuation solution for enterprise systems.
Providing 24x7 support, the solution is designed to protect systems and applications in a data centre following a disaster or a planned event such as scheduled maintenance, daily backups, system migrations or application testing.
Providing protection for mainframe, Unix, Windows NT and AS/400 systems, the SRDF creates real-time, host-independent, mirrored volumes of production information at a separate location.
Data and applications are automatically replicated between geographically separated EMC Symmetrix Enterprise Storage Systems over Internet Protocol (IP) networks.
The SRDF copies all user-specified data from the source to the target Symmetrix, enabling staff to switch from the source to the target quickly if necessaryIn the event of an outage, the SRDF enables fast switch-over to duplicate data located at the separate site. This enables systems to be up and running within minutes.
A single SRDF-configured Symmetrix can support up to four local or remote Symmetrix systems.

In July this year, IBM-owned storage specialist Tivoli released a disaster recovery solution to enhance its popular Tivoli Storage Manager solution.
Designed for the enterprise market, the Tivoli Disaster Recovery Manager is a completely separate product, which requires Storage Manager as a prerequisite and enhances many disaster recovery features already available with the storage product.
The Storage Manager, which Meta Group ranks number-one in storage management, already provides some disaster recovery features, including centralised storage management, SAN features, high-speed policy-based disaster recovery and data protection for e-mail, databases, groupware and applications.
The Disaster Recovery Manager helps with the automated generation of a customised server disaster recovery plan. It also provides off-site recovery media management and centralised management of a complete disaster recovery process.
Other features of the Disaster Recovery Manager include:
- the ability to generate an inventory of machine information required to recover the server and clients in the event of a disaster; and - executable scripts that help in the automation of recovery and electronic vaulting of storage pool and database back-ups to another Tivoli Storage Manager server.
The Disaster Recovery Manager is available for Unix, Windows NT, OS/390, MVS and AS/400 server systems.
