RE: Controlling a tape library remotely over an IP network

Hi Larry,

Thank you for the response! You are correct, I wasn't referring to exporting and mounting tapes, we do that through the web interface and I know that will work over IP.

I will investigate the virtual tape solution, that sounds like the way to go.

Thanks

Adam,

You can certainly "Control" the tape drive over the network. Such things a looking at the library, exporting tapes, mounting tapes. That's can be done with the web interface. That almost certainly isn't what you're after. :-)

The FC #280D card (aka FC #5761 ) is a fiber channel adapter. Now I know of customers who have installed equipment to convert FC to Ethernet and back on the far end. The connection between the locations was private fiber however so bandwidth was *LOTS. You mention MPLS which is good but how fast is the MPLS Network? Even if it's a full Gb speed a 500MB Backup would take a minimum of an hour and 5 minutes and I'm guessing that it won't be that fast. (If I'm wrong of course, you win, buuuuut you still need the equipment on each end to do the converting!)

A better concept would be something like a Crossroads SPHiNX unit on site which would then replicate the data off-site to a second unit after the backup has completed. The SPHiNX looks like a tape drive to your system but is actually a virtual tape library. This way the backup is done quickly (local fiber speeds) and then the replication can run off line as time permits.

Hi,



We have an IBM TS3500 tape library (and a Power 6 520 system). We are planning for some HA/DR scenarios at the moment and one of the possibilities is moving the Power System to a vendor data center. The tape library however will stay onsite (it's also used by a TSM server and that and the Windows servers are remaining onsite). The connection between our building and the vendor data center will be an MPLS network.



I was wondering if anyone has any experience doing this? Specifically,





1) Is it even possible? The tape controller is a 280D PCI-X Fibre Channel controller. Is it possible for this to work over an IP network?



2) Assuming it is possible, does anyone have any experience with the performance of such a set up?



Thanks
