||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.
||Unable to daisy-chain multiple Fusion D400Q or Fusion R400Q storage systems on a Firewire bus.||May-12-09|
|This issue was addressed and fixed in April, 2008 for the following systems:|
Fusion D400Q storage systems with a serial number beginning with J
Fusion R400Q storage systems with a serial number beginning with D
||Connecting a Fusion D400Q or Fusion R400Q to computer system with USB or FireWire requires a hard drive in drive bay 1.||May-06-09|
|The Fusion D400Q and R400Q must have a hard drive in drive bay 1 when connected via USB, FireWire, or FireWire 800. This requirement is due to the Oxford bridge chip that controls USB and FireWire connectons. Drive bay 1 is the top bay in the Fusion D400Q and the left bay in the Fusion R400Q. As long as there is a drive in drive bay 1, bays 2-4 are unconstrained.|
Note: This requirement does not apply to a direct SATA connection, which has no drive bay population requirements.

|Another manufacturer's previously-installed SATA driver may be accessing a Sonnet SATA card in error causing a drive access slowdown. For example, we have seen Fusion D400QR5 performance drop from 200MB/s to under 50MB/s in such circumstances. The solution is to remove the other manufacturer's SATA driver.|
