7 Setting up NetVault Backup Native Virtual Tape Library on the Dell™ DR4X00 Disk Backup Appliance1 Technical Setup/configuration Best PracticesThis section highlights key configuration and setup best practices to successfully add the DR backup Diskappliance for the use with NetVault Backup native Virtual Tape Library (nVTL) instance(s).1.1 General Setup /configuration Best PracticesRefer to the manufacture’s documentation for additional details on the following prerequisites. Ensure cabling configured correctly. Configure interfaces, protocol and addressing.o Configure Networking infrastructure to support Jumbo Frames (MTU=9000). Preconfigured system to run as the NetVault Backup Server and respective native virtual tapelibraries. DR4X00 preconfigured for use with the following attributes established:o Proper network connectivity with IP address or DNS name of DR4X00 Backup Appliance.o DR4X00 Backup Appliance(s) configured with the appropriate containers needed to hostthe NetVault Backup native VTL (nVTL) instanceo For each container defined a network share exported via CIFS or NFS of appropriatepermission and size.o All authentication requirements fulfilled such as Domain name, username and passwordfor users setup on DR4X00 unit to provide full access to the predefined containers andnetwork share(s) for use as backup repositories. In the case of the NetVault Backup nVTLsolution this should include full access to not only the NetVault Backup server but also allSmartClients intended for use.1.2 DR4X00 Setup/configuration Best Practices Each NetVault Backup nVTL instance should be created and configured to run within the domain of asingle DR4X00 Storage Container. This will allow for easy management of storage consumptiontherefore each NetVault Backup nVTL instance should run within its own container. Users should be created so that the NetVault Backup server user has full Read/Write access to thecontainer. This is a requirement for NetVault to be able to manage the configuration items andrespective objects created within said container during backup, access during recovery, and deletionupon retirement.1.3 NetVault nVTL Setup /configuration Best PracticesDue to various factors such as data set size, data set iteration or count, retention period, and change rate itcan be difficult to determine the best VTL size and configuration for any given deduplication situation. Oneof the best practices is to size the VTL to no more than 10x the physical available disk space or to assesshow much data the customer has to backup and the required retention periods for each set of data so asto not exceed either one of these two guidelines when creating the virtual media for the virtual tape library
