FC 10 Operation

George Nikoloudis_1 — Tue, 20 Nov 2001 17:00:16 GMT

Dear all
I would like to ask about the operation of FC10 when it is connected via hub with a V 2500 Class and running Oracle DB?

What I believe is that the Fibre Channel is bridged over the FC10 controller to 10 SCSI disks. When a transaction from ORACLE starts that has to perfrom scan in 3 disks then the Fibre Channel protocol payload is 2148 Bytes which means that it will collect these amount of data from disk that has first available address and then the second and so on.
Is ithe true?

The way that the FC10 is configured is like Arbitrated Loop and Running SCSI/Fibre Channel?
Or it is parallel (which I dont thing since the SCSI works in chains)?

Thanks a lot

FC10 are not SCSI disks; they are fibre channel disks.

On opetaration there is not difference,as disks are individual disks as they were SCSI. So you can configure access to disks the same way that SCSI.

There is one ( or two ?) FC-AL loops into FC10.

FC10's are just jbod (just a bunch of disks), and as Carlos stated, they behave much like any other disk.
