, a service set on node 1 that consumes 100 TB and a service set on node 2 that consumes 28 TB of the available 128 TB. (However, this is not best practice and not recommended.) This architecture scales dramatically and the maximum configuration can be seen below.

the deployment should center around what devices and services need to be configured on each node. In the following example Node 2 has failed and Service Set 2 has failed over to Node 1. Both service sets are running on Node1, but backup and replication performance will be reduced.

Physical IP ports The physical ports are the ports that are used to connect the HP StoreOnce Backup System to the - HP StoreOnce B6000 | HP B6200 Backup System Recommended Configuration Guidelines - Page 15

High availability and cabling In the HP B6200 Backup System the network connections for redundancy are configured to support high availability - HP StoreOnce B6000 | HP B6200 Backup System Recommended Configuration Guidelines - Page 16
HP B6200 Backup System supports four different network templates. This is in order to support various customer configurations node are bonded. 4. Template 4: Management on 1GbE network (2 x 1GbE connections per node) and Data on 1GbE network (2 x 1GbE bonded connection per node). This configuration - HP StoreOnce B6000 | HP B6200 Backup System Recommended Configuration Guidelines - Page 17
can only be accessed from the local subnet. (If a customer wants to access the B6200 management subnet from a client on Remote Site 1 or 2, "remote" manageability access is subnet on the local site.) Figure 7: Gateway is configured in the 10 GbE Data/Replication network (X on the Remote Site Admin - HP StoreOnce B6000 | HP B6200 Backup System Recommended Configuration Guidelines - Page 18
access path to the HP B6200 for data backup / restore jobs is within the local subnet. With this configuration none of the clients in Remote Sites 1 and 2 and none of the D2D units in Remote Sites 1 and 2 can contact the HP B6200 Backup System. Figure 8: Gateway is configured in the 1 GbE Management - HP StoreOnce B6000 | HP B6200 Backup System Recommended Configuration Guidelines - Page 19

later, the HP B6200 Backup System will re-evaluate all the IP Addresses and existing NAS shares may be re-allocated to a different virtual IP address. Hence, the best practice is to pre-allocate all IP addresses at initial configuration, irrespective of the number of physical nodes present.

sets. DBVTL1 has a very high throughput requirement and must reside on a service set that has 4 disk shelves and gives throughput capable of supporting 3.2 TB/hour. Note: HP strongly recommends that no node exceeds 50% of the storage available to it in order to maximize throughput performance - HP StoreOnce B6000 | HP B6200 Backup System Recommended Configuration Guidelines - Page 37

growth From the above layout of devices it should be apparent that, if the system requires upgrading with more capacity or the device needs to be enhanced to support replication, the preferred service sets are Service Sets 5 and 6. So, this is where extra capacity would be added for replication. 39 - HP StoreOnce B6000 | HP B6200 Backup System Recommended Configuration Guidelines - Page 40

However, the volume of seeding data that the HP B6200 Backup System needs to send over the WAN link is likely to be much higher than previous StoreOnce D2D models. This is because the HP B6200 Backup System is a Data - HP StoreOnce B6000 | HP B6200 Backup System Recommended Configuration Guidelines - Page 41

replication best practices with HP B6200 The main difference with the HP B6200 StoreOnce implementation is that replication is part of the service set. Each service set (associated to Node 1, Node 2, et cetera) can handle a maximum of 48 incoming concurrent replication jobs per node and can itself - HP StoreOnce B6000 | HP B6200 Backup System Recommended Configuration Guidelines - Page 45

deployments where a fan-in of up to 384 replication jobs to a maximum-configuration HP B6200 Backup System is possible (one stream per device). The sources (remote offices) are more likely to be HP StoreOnce D2D Backup Systems. For a large number of remote sites co-location is impractical, instead - HP StoreOnce B6000 | HP B6200 Backup System Recommended Configuration Guidelines - Page 49
source D2D and then configure a 1:1 mapping relationship with the floating D2D device, such as: SVTL1 on Remote Site A - FTVTL1 on floating D2D where FTVTL1 = floating target VTL1. Seeding times at the remote site A will vary. If the D2D at site A is an HP D2D2500 Backup System, it is over a 1 GbE - HP StoreOnce B6000 | HP B6200 Backup System Recommended Configuration Guidelines - Page 50
HP B6200 Backup System. 9. Finally set up the final replication mappings using our agreed naming convention decided in Step 1. At the remote sites configure to load balance the number of incoming replication sources across the available nodes as shown in the diagram below. In Figure 25 we show the - HP StoreOnce B6000 | HP B6200 Backup System Recommended Configuration Guidelines - Page 51
makes their behavior more predictable. In a failover situation, the performance impact on either backup or replication is likely to be lower because the backup load at Site B nodes and the replication load at Site B nodes are likely to run in separate windows at separate times. Figure 25: Balancing - HP StoreOnce B6000 | HP B6200 Backup System Recommended Configuration Guidelines - Page 52
page shows a full system approach and is a good overview of what is required. Note that: Each service set on each node is relatively at the same load (load balancing is a manual process) Each node has a single function, VTL backup targets node, NAS backup targets node, Replication target. This - HP StoreOnce B6000 | HP B6200 Backup System Recommended Configuration Guidelines - Page 53

happen without manual intervention. NAS target failover is via the Virtual IP system used in the HP B6200 Backup System - the service set simply presents the failed node Virtual IP address on the remaining node. FC (VTL device) failover relies on the customer's fabric switches supporting NPIV, and - HP StoreOnce B6000 | HP B6200 Backup System Recommended Configuration Guidelines - Page 55
enabled for scheduled backup jobs. No additional scripts or configuration are required in order to achieve seamless integration with the HP B6200 Backup System. In the event of a failover scenario, the backup jobs are automatically retried once the HP B6200 Backup System has completed the - HP StoreOnce B6000 | HP B6200 Backup System Recommended Configuration Guidelines - Page 56
a post execution script must be added to each and every backup job/policy. The customer can configure which jobs will retry in the event of failover (which is a temporary condition) in order to limit the load on the single remaining node in the couplet by:- o Only putting the post execution script - HP StoreOnce B6000 | HP B6200 Backup System Recommended Configuration Guidelines - Page 57
HP B6200 Backup System This section explains the options for monitoring the HP B6200 Backup System node has its own allocated 'local' storage within a couplet. Should this node's 'local' storage fill up, it will utilize some of the other node storage. Events are sent to warn you of the local node - HP StoreOnce B6000 | HP B6200 Backup System Recommended Configuration Guidelines - Page 58
should be. If storage reaches capacity, the customer should take the following actions: Please ensure that no further backups to VTL or NAS shares occur. If the device is being used as a replication target, pause replication jobs. Avoid using the StoreOnce B6200 in a failover mode unless necessary - HP StoreOnce B6000 | HP B6200 Backup System Recommended Configuration Guidelines - Page 59
