fitting 2x ultrium tape drives to a ML570 server

Hi,

I have a ML570 server currently running one ultrium2 tape drive from the on board scsi.

Is it possible for me to fit a second tape drive and if so what is the best way to go about it.

Unfortunately i cant bring the server down at the moment to have a look inside and see if there are any spare on board scsi slots available but from reading the specs this does not seem likely.
I would assume i am going to have to get a scsi card and run from that?

Any pointers would be a great help.

Cheers

Storage Controller

Integrated Dual Channel Ultra SCSI-3 (Ultra SCSI - 4 ready)

I suppose one goes to your hard drives and one to the tape drive?

Does not have the ML570 G2 listed anymore :/

But here you can see which parts are compatible with the ML570 G2:

Thanks for that Johan,

As soon as i get the chance i will bring the server down so i can check what is being used. Unfortunately this is our data server and it is working 24/6 the only day its free to be worked on is sunday...

Thanks for the links.
I can do some ground work so i have a clearer picture when i look in the server on sunday.

Re: fitting 2x ultrium tape drives to a ML570 server

just warning you on two things:

be sure to have enough power
be sure to have enough cooling

these two things are critical

ay be better to have an external unit if you want to manage two LTO drives

the LTO drives are both external, sorry should have said that in the first place...!

Ah!

But then you should be able to tell how many SCSI ports you have without opening the server.
Just look at the back of it :)

Re: fitting 2x ultrium tape drives to a ML570 server

i have looked at the back and there is only one wide scsi and that is being used by the existing tape drive, there are two narrow scsi ports but the IT manager refuses to use them as he says bandwidth is not as good and they are 'probably' raid controllers...thats why i want to open it up and have a look.

Re: fitting 2x ultrium tape drives to a ML570 server

using two LTO on the same scsi but is possible, if you use them alternatively.
If you plan to use both LTO2 drives at the same time, you should considere to have each of them on a dedicated scsi bus (could be also a HBA with dual controller)
The main problem would be that using two LTO2 drives attached to the same server, suppose you are getting data from the LAN.
Are you sure the LAN, the LAN controller, the server will all be able to feed data fast enough to keep those two unit in streaming mode?
You may run in trouble if you do not check carefully the power of your infrastructure, that is not enough to see if the drives can be connected to a old generation server, but you should also considere how it will work.
