| 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 |

| I daisy-chained two DX800s and my drives don't show up. | Mar-08-18 |
| Sonnet DX800 had 3Gb SAS expanders (Model Number SON005 and previous) and some had 6Gb SAS expanders (Model Number SON0011 and later).
You may mix models if you connect one to each SAS controller port. You may daisy-chain units togerther of the same model in any order, but if you daisy-chain mixed models SON005 and SON0011, then model(s) SON005 must come earlier and model(s) SON0011 must come later in the daisy-chain.
The performance does not change much with the faster SAS expanders when you use only 8 drives, because the 8 lanes on the controller card connect directly to 8 drives in one chassis without SAS switching. However, the performance is measurable better with 6Gb over 3Gb SAS expanders when you connect two 6Gb units concurrently or daisy-chain 6Gb chassis. In order to raffect this performance increase, Sonnet phased in 6Gb internal SAS expanders. A consequence of this performance bump is that a 3Gb expander will not work behind the 6Gb expander in a chain, only the in front of it. A mixed configuration works as well as two 3Gb SAS expander chassis together. Unfortunately, the SAS expanders in the SON005 units cannot be upgraded because the backplane going to SON0011 changed also. The good news is that every valid configuration will generally run faster, and in no case slower than before. |
