Redundancy options for the Virtual I/O Server include
multi-pathing, Redundant Array of Independent Disks (RAID) configurations,
and Link Aggregation (or EtherChannel).
Multipathing
Multipathing for the physical storage within the Virtual I/O Server
provides failover physical path redundancy and load-balancing. The multipathing
solutions available in the Virtual I/O Server include MPIO as well as solutions
provided by the storage vendors.
RAID
Redundant Array of Independent Disks (RAID) solutions provide for
device level redundancy within the Virtual I/O Server.
Some RAID options, such as LVM mirroring and striping, are provided by the Virtual I/O Server software, while other
RAID options are made available by the physical storage subsystem.
Link Aggregation or EtherChannel devices
A Link Aggregation, or EtherChannel, device is a network port-aggregation
technology that allows several Ethernet adapters to be aggregated, which enables
them to act as a single Ethernet device. It helps provide more throughput
over a single IP address than would be possible with a single Ethernet adapter.
