3. Storage modes
The following sections will describe, in detail, each of the storage modes that are supported by the
Kanguru QSX.
3.1 BiG
BIG Configuration – 000
Before using the Kanguru QSX in BIG mode, you first have to reformat your hard drives. For more
information, please see section 2.4 Formatting Large Volumes (for BIG and RAID0 modes), p.9.
BIG storage mode combines the two physical hard drives into a single large volume; resulting in a
seamless expansion of virtual volumes beyond the physical limitations of a single hard drive. When
writing to the QSX in BIG mode, data will be saved to Disk 1 first. Once Disk 1 has run out of space
then data will be written to Disk 2. This process will happen transparently. Hard drive A and B are
combined into a single virtual volume, with a storage capacity that is equal to the sum of each of
the physical hard drives A and B. BIG mode does not provide any data redundancy or performance
gain.
WarNiNG! If one of your hard drives fails, do not attempt to replace the faulty drive. Doing so will
void the warranty. If one of your hard drives fails, please contact Kanguru Solutions Tech Support at
508-966-4245.
Note: If Disk 2 fails, all data on Disk 1 will still be recoverable. Similarly, if Disk 1 fails, any data
in Disk 2 will be recoverable. It is advisable that you backup any data before sending the unit in for
repair. In order to access the uncorrupted data, change the QSX storage mode to JBOD (see section
3.2 JBOD, p.15). The remaining healthy disk will appear under My Computer.
