ok....basically the gist as I understand is that an FC array once configured with the HBA utilities looks like a SCSI drive....VERY similar to a SCSI RAID array. The key is the HBA utilities that it lets you carve up the array into LUNs (logical units) that then can be assigned to drive pointers or multiple hosts over an FC network...but FC switches cost a kings ransom and you really don't want to use a hub for anything other than a single system. FC comes both copper and fiber with the copper using a DB-9 varient that is WELL shielded.
Now if you want to export arrays, take a look at the iscsi stuff....very cool and it doesn't matter what kind of drives you use....the Networld+Interop iLabs guys did a raid5 array of thumb drives exported via iscsi over 802.11a to a win2k laptop that mounted them as dynamic drives.... Since you didn't include which HBA you're trying to use, nor the drive array type, nor the type of FC hub/switch...I just picked an HBA at random and assume you're using a reasonable array. I attached the readme file from a qlogic (my only experience driving an install alone) HBA. Such readme's are typically found with the card and are VERY specific to the HBA, since there is quite a bit more to an FC array than just the driver. You MUST have access to some sort of utility that can setup the FC array, or you're going nowhere. Opensource hasn't quite caught up on FC yet, and this is why I've stuck to qlogic so far...it's also why I'm leaning away from FC and more towards SATA. /brian chee University of Hawaii ICS Dept Advanced Network Computing Lab 1680 East West Road, POST rm 311 Honolulu, HI 96822 808-956-5797 voice, 877-284-1934 fax ----- Original Message ----- From: "Dustin Cross" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Thursday, February 26, 2004 2:23 PM Subject: Re: [luau] Linux Fibre Channel Server? > Brian, > > I understand how Fibre Channel works and the cost involved with buying the > HBAs and switch.
