Sonnet Tempo E4P and Leopard
I’m running a Sonnet Tempo E4P SATA card on a G5 and it’s causing OS crashes randomly. Sonnet have issued a firmware update for Mac Pros which solves the problem but if you are running a G5 it doesn’t install.
Just in case anyone with a similar system was thinking of upgrading, back to 10.4 for the moment!

Hi
For older PCI-X SATA/eSATA cards the new firmware Updater 2.1.2 installer reads:
-
Just discovered the 2.12 drivers that fix the G5 problem are on the site.
-
Sonnet has admitted to me that the new driver causes RAID 1 failures. This has occurred on 3 of our drives. One slice is labelled degraded while the other is seemingly ok. 1 of our drives has completely failed. Rather than labeling this a bug, they continue to offer it on their website. Be cautious in installation or upgrade ot make Leopard compatible.

We’ve noticed slower read speeds on 10.5, down to half on some systems, making the existing HD footage too slow to play.
We are using 3 MacPro quad systems with E4P and Fusion 500P, with 3-5 750GB seagates raided 0 together. Sonnet denies that there is a problem, but we continuing to complain to their support.
An internal, 3 drive raid in a Mac Pro is fine, no difference in speed from 10.4 to 10.5.
We may have to go back to 10.4 if a solution is not near, or find another esata card, if there is one that works better.

We decided to go back to 10.4 with a Mac Pro and E4P with Fusion 500P with 4 striped 750GB Seagates striped raid 0 in Mac Disk Utility with 128K option, because we recalled read speeds of 240 (BM speed test), With Leopard the reads were 160-180, too slow for 10 bit 1080 30P.
After installing 10.4, we loaded the Sonnet 2.1.2 driver from the website (the only driver on the site for this card), and the speeds matched that of Leopard, a disappointing 160-180 read.
We then looked for the previous driver, not available on the Sonnet web site for some reason, and found it in one of our other machines. We were not able to install it over the existing 2.1.2, so we RELOADED 10.4 and then the 2.1 driver.
The read speeds were back to 230-240, and we were able to play our 1080 material! This would indicate that the driver 2.1.2 is the problem.
