e1200-320 4Gb Fiber Channel Interface Card

Hi,

I'm trying to decide if i need two 4GB FC cards for an MSL6060 with 4 LTO-4 drives, or if one is enough.
Is there any speed advantage in having 2 instead of one?

thanks,
Fran

You can choose one card with dual FC HBA 4 GB ports or two FC HBA cards with one FC HBA port on each card.

MSL6060 Lib has got 2 FC HBA ports so you need same two for redundancy and performance too.

The Ultrium 4 drives need the full SCSI channel for each one. Each NSR has 2 SCSI channels, so you'll need 2 NSR to connect the 4 drives.
Connecting 2 Ultrium drives on the same channel is not recommended.

I might be late on this response but I also recommend you to check this advisory:

There is no NSR card with two 4G fc ports.

You will definitely want two NSRs, and even those, I believe will be a bottleneck for LTO-4. I'm pretty sure the bandwidth tops out at 230 MB/s (I get 215 tops writing to two drives). Search for lto-4 to find a few threads about this.

If this is not already bought, I'd recommend you look at the direct fibre msl4048, etc... libraries...
