I did not completely answer the first question. The dual ported cards do not perform as well as the single ported cards either. We discussed this with SUN when we decided to go with the PCI single ported SUN provided Qlogic cards. Basically, the chip that is on the card can really only support about 1.5 equivalents of FC throughput. The dual ported cards are for failover to a different switch and connectivity and when you are short on slots. In no way should they be considered a replacement for dual access to a LUN versus two separate cards on different IO boards (in SUN). If the card fails both paths are gone.
Again, this is a performance issue. Solaris just like other FC attached machines will scream if you put the PCI stuff in. What Eric says, depends. Yes, you can not do persistent binding of WWPN/LUN to a controller/scsi device so that each LUN is presented to the system with the same SCSI id. A SUN machine walks the bus. So, it really depends on the device. If each LUN/drive is a different WWPN then you have the problem. But, if it is like an IBM Shark where each LUN is presented with the same SCSI id and a consistent WWPN, then you do not have the problem. As I say, it depends. I only have experience with photons and IBM Shark and am speaking from that point of view. -----Original Message----- From: Joshua S.

And the FC attached 3584 uses SCSI address translation against WWN. We've got this running today on AIX, and if you do a lsdev -C|grep rmt, you will get the scsi addresses for each drive. Same with the library(/dev/smcX). This should mean that the Qlogic adapter can handle SCSI >> WWN translation.

I believe I heard about an issue with Qlogic adapters and SCSI address assignments. For Qlogic adapters you cannot define fixed SCSI address assignment (fixed relation between SCSI LUN's and FC World Wide Name). So if another FC device is added to the host, your SCSI assignments are messed up.

I cannot imagine why there would be a problem with this. I believe the same driver is used for both. The real issue is SBUS is going to be MUCH slower than the PCI card (25mhz vs 66mhz). Yes the IO slot board for PCI is about 10K and you may not have room for it, but it is really worth the difference in performance when you start running both FC disk and tape. -----Original Message----- From: Bruce Lowrie [mailto:[EMAIL PROTECTED]] Sent: Thursday, February 14, 2002 2:09 PM To: [EMAIL PROTECTED] Subject: Sun Solaris and Qlogic QLA2202FS (Sbus) and 3590-EIA All, Bringing up a Sun Solaris E6000 as a TSM Server and would like to use Qlogic's QLA2202FS Sbus Fibre Channel cards to connect to 3590-E1A. IBM's website only mentions support for QLA2200F (PCI). We can get Emulex LP8000S cards but these are single port whereas the Qlogic cards are available in dual port configurations.
