Any way from a RP4440 to an SC10?

[Marc Yoder]

Is there any path, Server - I/O card - Disk Array, from a RP4440 to a SC10?

[Marc Yoder]

One more thing. If there is a way.

Currently I have the SC10 mirrored (5+5) for our test server(L2000).

I want to use 2(non-mirrored) disks for a disk backup of our production server(rp4440) and use the other 8(4+4) disks for our test server(L2000).

I would rather not buy another disk array just to do disk backups from HP-UX 11i.

Hi,
How many BCC's installed on SC10?
If you have two BCC then you can connect two servers to SC10. Then you have two options (via DIP switch). Single bus or split bus. In split bus each bus can acces 5 disks. Refer to user guide.
You may have single bus and configure manually and make sure each host access to different physical disks.

Hi,

An SC10 can perfectly be connected to two servers.

If you connect each bus to two servers you have to check your SCSI id's in the chain (modify your scsi id on the cards) and you also need scsi cables with inline terminator.

You find more info about SC10 here

Thanks,
Since then I decided to unmirror my Test system array(SC10) and use 5 disks for a disk backup solution on our production machine(RP4440 - DS2300).
Is it better to attach the SC10 to the RP4440 directly or attach the SC10 to the DS2300?

I am afraid that attaching it to the DS2300 will cause a performance hit on the production array. Is this the case? I would like to avoid buying another SCSI card for the server.

If I do attach it to the DS2300, does it matter which side I attach it to, they are mirrored?

Hi,
I don't understand what you are trying to do. If you are chaining SC10 with DS2300, make sure that SCSI id are set unique through out the bus. Also remember per SCSI bus can support only 14 devices.
