[Firewire-users] Oracle RAC on RHEL3 or WBEL3

[Josh Hildebrand]

I'm about to order a LaCie d2 250gig drive, and two adaptec 4300 firewire
PCI cards..  The d2 series of LaCie drives seem to still have the Oxford 911
chipset.  I didn't want to risk the "Big Disk" series that reportedly has
the 912 chipset.

 

Can anyone warn me against this order?

Well the first thing we kneed to know is what drives you are using and what
interface cards you are using.  The interface cards are not usually the
problem.

 

We have found that the question is not as simple as Oxford 911 vs Oxford
912.

 

For instance the latest LaCie drives sem to work OK whereas the latest WD
drives don't although the earlier drives do.

 

It has crossed my mind that this might be worth a call to Oxford
Semiconductors and I will do this on Monday.

 

In the meantime can you call your disk manufacturer.  I know Western Digital
were stunned when they heard that anybody was trying to do this.

 

Regards

 

Bruce

I have not tried the latest kernels Manish posted, 
but the linux1394.org site still lists Firewire 800 
(IEEE1394b) compatibilty as 'ToDo'. 

I have tried OxSemi 912 chips and managed to mount 
drives, but they quickly report lots (GigaBytes) of 
bus resets and various other errors.

Does RAC on Firewire work w/ Oxford 912 chipset?  I know oxford 911 chipset
does.  Anyone tested their new one(s)?  I've read they have 912 and a 922.


Oxford Semiconductor's OXFW912 FireWire800 (IEEE1394b) to IDE (ATA7) bridge
chip is enabling LaCie's new Big Disk Dual FireWire drive to achieve data
transfer rates up to 88Mbyte/s.
