3.7. Chapter Summary
Storage Networking Terminology
RAID provides performance and data redundancy.
RAID 0 stripes data blocks over multiple disks.
RAID 1 provides data duplication (mirroring) between two disks.
RAID 5 provides striping of data blocks and distributed parity for data reconstruction in the event of failure.
RAID levels may be combined—for example, RAID 0 + 1.
JBODs are more economical than RAID but have no inherent redundancy or mirroring capability.
To maximize performance, software RAID on host systems can be applied against JBOD targets.
Tape subsystems may be SCSI, Fibre Channel, or Gigabit Ethernet interfaces.
Bridge products can bring legacy SCSI devices into an IP-based SAN.
SAN host adapters may include Fibre Channel HBAs and IP ...
