| 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. |

| Does the ATTO R380 Support OS X 10.9 (Mavericks)? | Oct-21-13 |
| Official ATTO support ends with OS X 10.8.5.
With OS X 10.9+, you will no longer be able to boot from a drive or array connected to an ATTO R380, and you will no longer be able to create new RAID groups. You can install current drivers for this card under Mavericks, but there will be no support from ATTO. Furthermore, Mavericks OS will complain at every boot about using unsigned drivers.
To transition to Mavericks, customers with an early Fusion DX800RAID storage unit equipped with an R380 RAID controller can purchase from Sonnet an R680 RAID controller with an included cooling upgrade kit.
All Fusion DX1600RAID units were equipped with an R680 RAID controller, which has complete Mavericks support.
The Fusion D800RAID and R800RAID storage units are not compatible with the ATTO R680 card. To transition to Mavericks, customers with a Fusion D800RAID or R800RAID must upgrade to a DX800 storage unit which includes an R680 controller. The drives can be moved with the RAID array intact. If you would like to make this upgrade, contact Sonnet sales to inquire about purchasing a DX800 without drives. |

| Can I use an ATTO R680 with the R800RAID or D800RAID? | Jun-24-14 |
| Can I use an ATTO R680 with the R800RAID or D800RAID? The ATTO R380 that come with these storage units does not have full OS X 10.9 support and I want to migrate to Mavericks.
Background:
The D800RAID and R800RAID were qualified with the ATTO R380 RAID controller card. The R380 is a 3Gb SAS card will link to modern 6Gb hard drives at 3Gb. The R680 would link at 6Gb, however, these chassis were never qualified at 6Gb, and migrating to an R680 means one must force the R680-to-hard drive link to 3Gb for reliable operation. Because SATA hard drives are not capable of saturating a 3Gb link, the performance impact is minimal.
After installing the R680, and before formatting the RAID array, force the link to 3Gb...
Run Terminal, and type: sudo ./atsasnvr -k 3
A reboot is necessary for the change to take effect.
You can now use the R680 with the D800RAID or R800RAID. |
