| ATTO R380 RAID Software (Feb. 2008) | Aug-05-09 |
| The February 2008 release of the ATTO software broke the "automaponboot" feature, in which an array that is moved to another machine will be automatically recognized. Sonnet will not be posting this update. For customers who may have upgraded directly from ATTO, we recommend they change the automaponboot setting to 'disabled.' This way on each reboot the mappings will persist.
The new ATTO software release included these enhancements:
* Staggered startup.
* Autorebuild - RAID will automatically start rebuilding if it finds a damaged disk replaced by a clean one.
* Adaptive read-ahead policy - will read ahead for long data streams, not for short ones. |

| What is the default drive timeout in Fusion RAID systems? Should I change it? | Mar-24-10 |
| The default drive timeout Fusion RAID systems is 30 seconds. The default is generally the best, but may be insufficient for some Seagate drives, which in rare instances may not respond within a 30 second timeout and consequently appear as degraded. If you are using Seagate drives, Sonnet recommends setting the timeout to 60 seconds, with the CLI command, "set raidcommandtimeout 60000". |

| My storage shows 10% more capacity under OS X 10.6 than under OS X 10.5. Why? | Mar-24-10 |
| With Snow Leopard (10.6), Apple adopted the standard usage of terabyte (TB) which equals 1,000,000,000,000 bytes = 10-to-the-12th bytes. Hard drive manufacturers have always specified drive capacity with standard usage which will now match what Mac OS X reports.
WIth Leopard (10.5) and previous versions of Mac OS X, Apple used the binary interpretation of terabyte, (technically a tebibyte) = 1,099,511,627,776 bytes = 2-to-the-40th bytes. Windows also uses binary interpretation.
Under Snow Leopard, drive capacity will be shown per drive specifications. For example, under OS X 10.6, a 1TB drive will appear as a 1000 GB capacity drive (but under OS X 10.5 as a 909 GB capacity drive). For additional information see support.apple.com/kb/TS2419.
What does this mean in real terms? Do I get an immediate increase in storage space?
Formatting or actual capacity does not change at all, only the reported capacity because of the change from base-2 to base-10.
Should I reformat the drives before attempting to plug in a previously 10.5 formatted unit into a 10.6 machine or vice versa?
Reformatting is not necessary at all.
What happens if I plug a 10.6 formatted unit into a 10.5 machine or vice versa?
The volume is seen normally. It is completely compatible and can be transparently moved back and forth. |
