| 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. |

| 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. |
