SANOS Overview
3
critical data services such as MPIO (Multi-Path I/O), MC/S (Multiple Connections per
Session), Microsoft VSS (Volume Shadow Copy Service), Microsoft ODX (Offloaded Data
Transfer), and VMware VAAI (VMware vSphere Storage APIs for Array Integration). In the
periphery, there are management service daemon to provide user interface operations, C2F
(Cache to Flash) mechanism includes BBM (Battery Backup Module) / SCM (SuperCap
Module) and M.2 flash module to protect cache data from power shortage. These key
enterprise storage features are all together in a single box.
Under the operation of dual controllers, HAC (High Availability Control) module has a
heartbeat mechanism to detect whether the other controller is alive. Cache mirror
synchronizes the memory data of both controllers including the status and storage
configuration. When one controller fails, the other controller can seamlessly take over all the
tasks of the failed controller thanks to this cache sync. In addition, zero system downtime
for the dual controller system takes place during firmware upgrading period.

SANOS Storage Pool Architecture
QSAN storage pool supports a variety of 3.5”/2.5” SAS/NL-SAS HDD and 2.5” SAS/SATA
SSD flash drives. Figure 1-3 shows the storage pool architecture. Several disk drives are
combined together to form a “disk group” with RAID protection. Then several disk groups
can be combined to form a storage pool. A volume (virtual disk) is then created out of the
storage pool and served to application servers over either iSCSI or Fibre Channel
connections.
