GVP A530 and multiple scsi-drives ?

[darksun9210]

i've had on one scsi chain...

ID7:- A530 controller
ID6:- external CD/RW
ID5:- external DDS3 Dat drive
ID4:- external 73Gb SCA ultra scsi
ID3:- external 73Gb SCA ultra scsi
ID2:- external 73Gb SCA ultra scsi
ID1:- A1200 Blizzard PPC scsi conroller
ID0:- scsi2ide bridge/IDE2CF adapter/4GB CF card (in the A530).

so yeah i'd say its happy with multiple drives.

i use Diavolo to run the DDS3 drive. i only have DDS2 tapes though, but no big deal, i only use it rarely. but runs like a champ. got my old A4000 backed up on there. when i get a stable working 3.1rom'd 060 based machine, i may do a full restore one day ;-)

@Colani1200
i have both machines on the same SCSI bus, the A530 can see the compact flash card and boots the A500 from there.
the A1200 can see the CF card, but has an IDE drive with a higher boot priority, so boots from that instead.

with the PPC cards (and other scsi controllers i'm certain), you can change the scsi ID of the controller, so allowing multiple controllers on one bus. handy for data sharing, especially as my A500 has a bit of a poor ethernet implementation that can't currently rival a good 56k modem for throughput. so i download what i need on an A1200, dump to shared disk, and install/run on the A500. easy peasy

they were the *ahem* *COUGH* DVD ISO storage array i had hanging off the back of the apps server at my last work place. driven by a PM1564U3 raid controller, with the DDS3 drive and CD/RW. the company got amalgamated, so we had to find homes for "unofficial" company stuff before it got audited. :-D

as i don't have scsi on any of my PC's even though i do still have the raid card, there is no point using them for on line storage given the current price of terrabyte SATA drives at the moment. So they are hooked into the only machines i have that can use them.... most of the time, they sit there not even switched on...

@LoadWB
lol, pay?  :lol:

@Colani
its pretty safe. amigaOS isn't as greedy as Windows when it comes to drive ownership. looks at the drive, reads the RDB, mounts the partitions. thats it. no drive polls, no filesystem journaling, no continuous seeming random registry reads or swap space paging, plus SCSI is fairly clever when it comes to multiple controller access as in all the other devices on the bus, know what what is happening to what device, so no multiple command issues from different controllers to read or write the same disk block at the same time.  :-)

i like the 68pin ultra scsi Sun unipack drive cases.
auto detect if they are at the end of the device chain and apply high/low termination accordingly :-)
