Customer: One of the World’s Largest Telecommunications Companies
System: SAP Databases for Backup and Disaster Recovery

 

A Brief description of Environment:

One of the largest telecommunication companies in the world has unique requirements for backup and disaster recovery. Our team put together approximately 90 Large SAP databases, varying from 50 GB to 1.3 TB and averaging 650 GB, utilizing an Oracle 8x (64 bit) back-end built on HP UNIX 11x (64 bit), operating in the EMC Symmetrix Remote Data Facility environment.

 

Client Requirements:

	Setting up SAP and Oracle Databases in the data center, data center moves, and replicating databases across development, test, consolidation, integration and production environments.
	Providing 7×24 database availability with very short (15 minutes) weekly downtime for Taking offline backups and no downtime for other types of backups.
	Affording faster recovery times in case of database crash using the hybrid of EMC SRDF technology with Oracle 8 Recovery tools.

 

The Solution:

Moved existing databases to new location, replicated same, moved production environments to a new datacenter location across the United States using EMC sophisticated multi-hop technology with WAN setup across the US using mirror replication procedures and fault tolerant software.

 

The Model:

Software includes a complex mix of HP Openview’s OMNIBACK , II 3.1 tool in tight integration with SAP’s brtools combined with EMC’s Symmetrix Remote Data Facility (SRDF), a volume management tool that provides high availability of data. Omniback II 3.1 is used for backing up all production databases transparently in the background using EMS’ Symcli Ver 4x, SRDF volume management and data storage utilities.

Hardware for production databases consists of a multi-million dollar fault resistant architecture using extraordinarily fast HP V/N class servers with over 26 CPUs connected to two 97 10 Timberwolf DLT Tape Libraries, each having 20 70GB DLT tape drives and running Omniback II 3.1. An EMC 3930 unit houses a vast number of disks that are assigned to each of the production databases. A separate FDDI network backbone is designed to handle the backup data traffic that is independent of front-end network for application users.

All SRDF links between the backup host and the application host transparently maintain the data consistency and the integration without affecting the front-end production environment. The mirrored backup EMC also provides for disaster recovery by interconnecting EMC over a Fibre Channel WAN using multi-hop technology. The backup EMC and the production EMCs can be set miles apart in two different data centers to provide the ultimate solution for faster disaster recovery operations.

Our team of three highly skilled DBAs used a complex integration of EMC SmmConsole with brtools and the Omniback utility to operate and maintain this environment.
