101 Fusion storage system activity lights are always on with Seagate ES.2 (Enterprise) drives installed in the drive bays.Oct-22-10
Sonnet engineering has fixed this issue with some Fusion storage systems. This issue was addressed and fixed as follows:

APRIL, 2008: in Fusion D400Q and Fusion D500P systems with serial numbers beginning with J.
MAY 20, 2008: In Fusion D800RAID with serial numbers beginning with G.
All versions of Fusion R400Q and R800RAID are compatible with Seagate ES.2 Drives.

Note: Seagate ES.2 drives have lower performance than Sonnet recommended drives.
 
202 Under Mac OS X 10.5.6, the PCI Express Expansion Slot Utility (early Mac Pro) always reports 8x, 1x, 1x, 16x no matter how its set.May-06-09
The bus lanes actually get set correctly under Mac OS X 10.5.6 but they are not reported correctly in the Expansion Slot Utility. The actual settings can be verified by booting under another version of Mac OS X. Sonnet has filed a bug report with Apple.
 
387 How do I replace a failed drive under warranty if I'm in a sensitive/classified environment and can't send the old one back?Mar-23-10
Seagate has a provisions in place to deal with replacing drives in sensitive / classified environments.

1. Start by going to the Seagate Warranty Validation page http://support.seagate.com/customer/warranty_validation.jsp

2. Input all the neccessary drive information and continue until you are issued an RMA or return#.

3. Contact Seagate at http://www.seagate.com/www/en-us/about/contact_us to request a "Certificate Of Destruction". Seagate will send the COD via e-mail along with instructions on how to destroy the drive to their satisfaction. Certain parts of the drive will need to be shipped back to Seagate along with a filled out copy of the COD.

4. Once Seagate receives the COD and associated drive parts meeting their requirements, a replacement drive(s) will be shipped to the address set forth in the RMA.
 
445 What is the default drive timeout in Fusion RAID systems? Should I change it?Mar-24-10
450 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.
