Enterprise Backup Solution User Guide xiii 1 Features Enterprise Backup Solution Backup Software Features The Compaq StorageWorksTM Enterprise Backup Solution (EBS) is an integration of backup and restore application software with industry-standard hardware for a complete enterprise class solution. Compaq has joined with leading software companies to provide software solutions that support the backup and restore processes of homogeneous and heterogeneous operating systems. EBS software partners' backup solutions incorporate database protection, storage management agents, and options for highly specialized networking environments. Storage management software focuses on data backup and restore using an automated digital linear tape (DLT), super digital linear tape (SDLT), or advanced intelligent tape (AIT) library and Fibre Channel technology. The EBS combines the functionality and management of EBS Storage Area Network (SAN), high-availability software, and scaling tools to integrate tape and disk storage subsystems in the same SAN environment. Depending on the specific software solution you are using, the EBS with a backup software solution can include: Compaq ProLiantTM servers running Microsoft Windows NT 4.0, Windows 2000,
or Novell Netware Compaq ProLiant servers running RedHat Linux and SuSE Linux Compaq AlphaServerTM servers running Compaq Tru64 UNIX
Compaq TaskSmart N-Series Network Attached Storage (NAS) Sun UltraSPARC servers running Sun Solaris Dell PowerEdge servers running Windows NT 4.0, Windows 2000, or Novell Netware Hewlett-Packard NetServer servers running Windows NT 4.0, Windows 2000, or Novell Netware Hewlett-Packard L/N/V Class 9000 servers running HP-UX Enterprise Backup Solution User Guide 11 Features IBM NetFinity servers running Windows NT 4.0, Windows 2000, or Novell Netware IBM RS/6000 servers running AIT NOTE: Compaq has provided a compatibility matrix as an aid to matching EBS components. You can access the compatibility matrix at: www.compaq.com/products/storageworks/ebs/EBScompatmatrix.html NOTE: To determine the specific features of the backup software selection you are interested in, visit the software vendor's website for details. Servers in an EBS solution can share one or more Compaq StorageWorks DLT, SDLT, and/or AIT libraries interconnected through Compaq StorageWorks Fibre Channel SAN Switches. Online storage, such as the Compaq StorageWorks Enterprise Modular Array (EMA), Enterprise Storage Array (ESA), Modular Array (MA), and RAID Array (RA) can also be connected with Fibre Channel SAN switches. Solution Components The following components make up the EBS: Servers containing Fibre Channel Host Bus Adapters SAN Switch, Fibre Channel Storage Switch, Fibre Channel Arbitrated Loop (FC-AL) Switch, or Fibre Channel Hub Modular Data Router or Fibre Channel Tape Controller-II Fibre Channel to SCSI Bridge Tape Library Enterprise data backup and restore can be accomplished with different tape devices in various configurations, using a variety of transport methods such as the corporate communication network, a server SCSI bus, or a Fibre Channel infrastructure. EBS uses a storage area network (SAN) that provides dedicated bandwidth independent of the local area network (LAN). This independence allows single or multiple backup or restore jobs to run without the network traffic caused by data protection environments. Depending on the backup software solution, submitted jobs are run locally on the backup solution server to which the job was submitted. Data, however, is sent over the SAN to the tape library rather than over the LAN. This achieves greater speed and reduces network traffic. Jobs and devices can be managed and viewed from either the Enterprise Backup Solution User Guide 12 Features primary or any server or client connected within the EBS which has the supported backup software solution installed. All servers within the EBS server group can display the same devices. NOTE: The features listed in this document are a composite of features for all EBS software solution partners. You should research the specific functionality of the backup software solution you are interested in.
