Figure 1-2 shows the SANOS system architecture with a single controller configuration. The
data path is back and forth between the host interfaces and disk drives via the backplane.
The LVM (Logical Volume Management) is the core to handle this data flow between them.
It provides a method of allocating space on mass-storage devices that is more flexible than
conventional partitioning schemes. In particular, a volume manager can concatenate, stripe
together or otherwise combine partitions into larger virtual ones that administrators can re-
size or move, potentially without interrupting system use. Of course, it may rely on the
system resources manager to arrange the processor time slot and scheduled tasks.

SANOS System Architecture with Single Controller Configuration
Base on LVM technology, it develops the features of auto tiering, thin provisioning, SSD
cache and also data backup functions of snapshot, local clone, and remote replication.
Upon LVM, QSOE (QSAN Storage Optimization Engine) which we are proud to develop,
increases IOPS performance and overall system throughput. SANOS also supports several
