3 Concepts specific to StoreOnce B6200 Backup system The HP B6200 Backup system provides up to 8 separate nodes in a single appliance with a single management GUI for all nodes, and failover capability across nodes within the same couplet as standard. The best practices for single-node StoreOnce Backup systems apply but significant thought must also be given to mapping customer backup requirements and media servers across devices located on up to 8 separate nodes. The preferred mapping approach is to segment customer data into different data types and then map the data types into different backup devices configured on the HP B6200 Backup system so that each backup device is its own unique deduplication store. This approach also improves deduplication ratio; similar data types mean more chance of redundant data. Network and Fibre Channel configuration requires particular care to support HP autonomic failover, which is a unique enterprise class feature of the HP B6200 StoreOnce Backup system. This is described in more detail in the relevant chapters of this guide. This chapter describes basic concepts only. The HP StoreOnce B6200 Backup system The Enterprise StoreOnce B6200 Backup System is a deduplication backup appliance supporting Catalyst, VTL and NAS target devices, which provides scale-up and scale-out performance with a user capacity of up to 512 TB and throughput of up to 28 TB/hour. The architecture uses high levels of redundancy supported by 2-node couplets that allow autonomic failover to the other node in a couplet should a failure on one node occur. Any backups will restart automatically after failover.

The HP B6200 Backup System is replication compatible with existing HP StoreOnce Backup Systems and can support a fan-in of up to 384 concurrent replication streams (up to 48 per node). 22 Concepts specific to StoreOnce B6200 Backup system
