Failover/Resilience

The HP B6000 Backup System is designed to provide resilience, as follows.
Nodes are connected as fault tolerant failover pairs
System hardware is designed with no single point of failure resulting in a highly resilient
datapath to system data storage
Proven RAID 6 technology reduces the risk of data loss due to disk failure in the data storage
Dual power supplies are included as standard

Service set

The service set is the set of services that run upon a node. These include NAS, VTL, Replication
and other services.

Network and FC cabling guidelines

To ensure resilience and failover there are some network and Fibre Channel cabling restrictions
that the customer must know and observe.
Please refer to the HP B6000 Installation and Configuration guide and the HP B6000 Best Practices
guide for a more detailed discussion of these restrictions and how they should be implemented.

Network restrictions (HP B6000 only)

IPv4 is supported; IPv6 is not supported
DHCP is not supported
DNS is supported
A maximum of two sub-nets is supported
Network bonding is required, but network bonding between 1G port and 10G ports is not
supported.
Customers can only have one external IP for configuring the B6000 Management Console
(GUI and CLI).
There is no VTL support on Ethernet
NAS shares and replication data use the same Ethernet channel
If you wish to use a separate Ethernet channel for replication, you must use Fibre Channel for
backup to VTL targets
The network configuration applies to all nodes in the cluster. For example, you cannot have
separate network configurations for each rack in a two-rack system

FC restrictions

HP B6000 Backup System supports switched fabric topologies only.
Direct attach (private loop) and direct attach (point-point) topologies are not supported
topologies.
The preferred topology for the HP StoreOnce Backup System is switched fabric using NPIV
(N_Port ID Virtualisation).
Due to complexities in multi-hosting tape devices on SANs, it is best to make use of zoning
tools to help keep the backup/restore environment simple and less susceptible to the effects
of changing or problematic SANs.
