Fibre Channel Hardware List...

2001-02-08 Thread Matthew Jacob


I've just put up a simple Fibre Channel "Suggest Hardware Matrix" as the
beginnings of what one might expect for Fibre Channel in FreeBSD- see

http://people.freebsd.org/~mjacob/Fibre_Channel_Hardware.txt

Suggestions welcome!

 Suggestions welcome!

As you asked, just suggestions here from someone who is putting
FC stuff together for my own :-) -

"Very expensive (in my opinion)" - if you mention "expensive"-"not
expensive",
I would propose to add rough price estimations too - this might be of
interest
for beginners imho.

"I have used lots of different Seagate and a few IBM drives and typically
have had few problems with them." - and absolutely nothing about single
channel vs dual channel, issues with putting them together etc ?

What's up with "1026Gbit" - is it really true ?

Regards,

Andrei

No, it should be 1.062 Gbit (the current fullspeed FC). Dual speed is coming
soon. Don't ask for prices :-(

Oh, yeah, about this, 2300 support is comint "real soon" -this will be 2GBit.

Thanks ! And for the page too - very good and useful !!

For poor owners of 2GB-ready Seagates, I wonder can you advise
on any affordable 2GB enclosure ? Everything affordable I saw is
a bit old and 1GB-only. Of course, I don't now if it will make any
real difference - will burst speed twice as fast or what ? Would be
really nice to hear from someone knowledgeable :-)

Thanks again !

Andrei

About the 2Gb drives, sorry! I have no clue as yet about this!

 
 Thanks again !

You're welcome!

Sorry for the confusion, I meant drives capable of 2 Gbit/s,
which the 2300 will supposingly support. My question was
that many enclosure support 1 Gbit/s, right ? So, I was
wondering have you heard about those which support 2 [Gbit/s] ?
Because one do need to have something in between the 2300 card
and Cheetah-4 FC drive, right :-) ? Adapter in a case of 1 drive
only, I presume, and enclosure in the case of multiple drives.


 
  Thanks again !

 You're welcome!

I've heard that Ancor has one. I think that Brocade has one too. I have had
access as yet to neither.

Yes. I have no idea who is, as yet, building enclosures with 2Gb interfaces
either.

This is much like Ultra3- it took at least a year after Ultra3 came out (with
disks ready to go) to find a JBOD that would be Ultra3 to the JBOD itself.

It's true, we at Qlogic (formerly Ancor) do have a 2Gb switch in the
works. We demoed said switch at Comdex. It's pretty impressive watching
your data stream by at 198MB/second! Interestingly enough, said switch
runs Linux as the underlying OS (if I had been at Ancor 1 month before I
got here, we'd be running FreeBSD instead!)

that's easy to fix:

Can you please send me all your changes and drivers for linux in your product?
