For all us "common folk", would someone be so kind as to explain what this item is used for? Is it some form of of superfast VCR but for computers?
Thanks,

It is an expansion card that provides a fibre optic connection to an XRAID (no longer produced by Apple) or Promise VTrak E-Class RAID. These provide massive storage (up to 16 TB per device) for things like video production.

Boot Xserve from SAN storage?

Answer
I have booted an Intel Xserve from an EMC AX4 san array via 4gb SFP fiber optic using an 8gb EMC 300M switch. The biggest issue I have is I cannot multipath to both SPA and SPB. If I force a single path in my zoning then the storage works fine.

Can someone please tell me what is the benefits of using just one of the 4gb plugs instead of both? right now at my job everyone is using just one?
everyone at my job has mac pros with the fiber cards installed in them but everyone is only using one of the two fiber plugs on the card? is there a benefit to using both of the plugs? just please explain it to me if it would be worth it to have both fiber plugs in use or if one will do it? i work for television network and we transfer a lot of data back and fourth mostly graphics videos and audio?

Answer
Two connections has twice the speed as one.
Consider each as an individual connection. So a single 4Gb requirement uses one, but when you need more bandwidth, use two.- Answered by Peter C from Milpitas

What's the difference between using the dual-channel or quad-channel version in a video SAN setup?
We're looking at setting up a video SAN for 3 machines. Are the Dual-Channel cards sufficient or should we go with the Quad-Channel cards? What's the difference?

Best Answer
A Dual-Channel 4Gb card will do for each MacPro in order to connect via the SPF connectors. Quad-Channels are mostly used on servers for redundancy and other specific cases. Going into Quad will not make the connection faster.

Can anyone recommend brands and/or manufacturers of optical transceivers that they have used with the Apple Fiber Channel cards?
I do not see in the Apple documentation any qualified transceivers for using a fiber switch.

Answer
If you're talking about the fibre switch, Qlogic is nearly perfect and I would highly recommend that.

Can the Apple Dual-Channel 4Gb Cards from the PowerMac G5's be used on the Mac Pros and vice versa?
The new cards seems to look like the older Powermac G5 cards. Are the old and new interchangeable from PowerMac to Mac Pro and vice versa?"
- Asked by Stacey B from Montreal
- 09-Nov-2009
- Flag as inappropriate
Answer
Older PowerMac G5s had the PCI-X bus whereas the Intel Mac Pros use PCI-Express. The 2005 Power Mac G5 computers made the switch to PCI-e. The Dual-Channel 4Gb card can only be used in PCI-e (PCI-Express) slots which are found in all Intel Mac Pros and Intel Xserves. If you successfully used the fibre card in your PowerMac G5 it was one of the later G5 models so you should be fine. You can always check the manuals at "(http)://manuals.info.apple.com" for your particular G5 to identify what bus you have.

Can I use a G5 tower as a file server and connect it simultaneously to a Mac Pro (via Fibre Channel) and to an Ethernet network?
I have several G5 towers that I'd like to repurpose. I'm wondering if I can install a Fibre Channel card in one, and a Fibre Channel card in my Intel Mac Pro, and connect the two. The idea is to have block-level access (as if the G5 and all the drives attached to it were directly connected to the Mac Pro), and have access via Ethernet for other computers on the network.
We are doing video editing with Final Cut Studio, and several computers need access to the same files. However, two (an iMac and a Mac Book) only have Ethernet or FW800 connections.
Are we barking up the wrong tree? Would 10G Ethernet or iSCSI be a better solution? I was thinking Fibre Channel because there's more history with it.
Also, I have an older Xserve G4, so I could utilize the XServe OS license from it on the G5.- Asked by Bruce H from Buford

Can this fibre channel be configured for multipathing?
- Asked by Brent W from Meredith
- 08-Oct-2009
- Flag as inappropriate
Answer
Yes, as long as the software supports multi-pathing. As far as I know, the default System Preferences supports multi-pathing as I noticed our Xsan performance doubling when both fibre channel ports were being used.

Does this card include SPFs or are they extra?
- Asked by David B from Ridgewood
- 29-Sep-2010
- Flag as inappropriate
Answer
SFPs are attached to both ends of the included fibre cables. If you want to use different fibre cables without built-in SFPs, then yes, you'll need to get additional SFPs.

Can I use Brocade SPFs on my apple HBAs or do I have to buy SPFs through apple?
I just got two shiny new HBAs so that I can connect them to the EMC SAN. Unfortunately I didn't know about the SPFs not being included and that they would be anything other than optical.
I need to get this project started no to reach my deadline.
Could I simply "recover" a few SPFs from my Brocade switch until we get the official ones form applE?- Asked by Gcc A from Glendale

Answer
Apple's cards are OEM versions of the LSI Fibre Channel cards. I've used several different Apple cards over the years (both PCI-X and PCI Express) and they've all used common LSI controllers. (I think the current 2 port 4 Gbps PCI Express card is an LSI7204EP-LC. I have an older dual 2Gbps PCI-X card from Apple which is a LSI7202XP-LC)

will this card work for an older xraid
I want to upgrade the mac that I have to run final cut pro server - it is not an intel mac hence the upgrade - I need to know if I will be able to use my old XRaid as the raid 5 storage for this intel mac for FCP server with this fiber card in it, the mac I have currently running the xraid is a pci-x buss mac and the cards won't swap, and will the raid admin software run on the intel mac - it is a Mac Pro, dual core intel Xeon 3 Ghz - or is there another way to do this.
thanks in advance

Answer
Almost any fiber based storage will work, including your old Xserve RAID. Use RAID Admin (java app) to admin the Xserve RAID hardware. This PCI Express card should work.

I have a Mac Pro Raid Card fitted, can I add the Apple Dual-Channel 4Gb Fibre PCI-Express card as well ?
AppleMacPro Server One 2.80GHz Quad-Core/8GB/4x2TB fitted with Apple Mac Pro Raid Card, I want to connect to a Promise VTrak E-Class 8x SATA RAID Subsystem (TV272ZM). I assume I need a Apple Dual-Channel 4Gb Fibre Channel PCI Express Card (MB842G/A). Is there a free slot in the machine to allow me to have both cards fitted at the same time.
