Managing Drives
The Drive Management page provides settings for managing storage and lets you apply global settings for
drives on your ix2 Network Storage.
Setting Write Caching
Select a value for disk write caching.
Write caching is a mechanism that attempts to separate the fast processing speed of the ix2 from the
relatively slow mechanics of actually writing data to drive.
With write caching disabled, every write to drive causes the ix2 to wait while the data is written to drive,
which can slow performance. When write caching is enabled and the ix2 sends a write request to the drive,
it writes the data to cache (which is much faster) and sends an immediate acknowledgement to the ix2
saying the write is complete. The system proceeds without waiting for the data to actually get written to
drive, which occurs in the background.
While write caching does improve performance, there are some risks. The system responds that the data
is written to drive when in fact it has only been written to cache. Should the ix2 lose power, any data not
completely written to drive is lost forever.
This is because cache memory is volatile. If you lose power, the contents of the cache are lost. Therefore,
if there were any pending writes in the cache that were not written to the drive, they will be lost forever.
Using a UPS (Uninterrupted Power Supply) can mitigate the risk associated with write caching, which is
why it is recommended to only enable this feature when a UPS is connected.
Applying Global Drive Management Settings
1. Click
Settings.
2. To change the protection, choose a value from the drop-down menu:
●
Mirror (RAID 10)
Uses half of the storage space for protection, leaving half for actual data.
●
Striped (RAID 0)
Distributes data across several drives in a way that gives improved speed at any given
instant.
●
None
Turns off data protection and leaves your data vulnerable to data loss.
3. Select a value for disk write caching.
4. Check Enable periodic consistency check to enable a monthly parity or mirror consistency
check. The check helps to prevent a single drive failure from becoming a two-drive failure,
resulting in data loss. The check runs for several hours and can affect performance of the ix2. If
you do not want to run the check, uncheck this option.
5. Click Apply to save your changes.
