Question : Problem: Using Cisco 3560\3750 SFP port for Tape Library

I am going to be setting up a tape library. I am told with the library that I'm getting that there are two ways to set it up,

[svrs to be backed up]----->thru the lan---->[backup svr]--->SCSI--->[tape library]

or

[fiber nic]------>[fiber bridge]------>[tape library]

My question is, can I use a cisco switch (3560\3750) and plug the tape library in one of the spf ports on it?

I want to buy the switch to act as the 'fiber bridge' and since it's a gb switch and all the servers have gb nics, i just want them to have a gb connection to the tape library which itself is connected by fiber.

Also, in buying the switch, it says the SFP ports are empty, do I need to purchase a specific gbic or fiber module to plug into the spf port? And i'm assuming this module will depend what type of fiber connection is coming off the tape library, would that be correct? like SC to LC or someting another

Since the only difference is the connection path, I'd forward it to look at the idle-time or hold-downs on the interm routers used to determine which connections are dead and which arent. Is there anyway to configure the clients connecting via WAN to send keepalives across the link every 15 seconds or so ? This is another way to avoid anyone without the experience having to track down the router configuration nuances where these timeouts may lie. It won't be on a CSU/DSU unit, they don't care about Layer3+4 circuits. It's almost guaranteed to be an issue of default router dead-connection determination algorithm.  Send it off to network, that's what they're there for ;)  Heck, most people woulnd't have even gone as far as you did and verify the application is properly configured! You've given it to them isolated on a silver platter.... no problemo......
