Re: [Xen-users] Emulex SAN card support

As a rule, we want to support all reasonably modern hardware: the card you're interested in ought to work. Server class hardware is generally the least awkward to run on; laptops and cheap desktops tend to cause more compatibility issues.

Occasionally device hardware won't work due to bugs in the device drivers: these bugs are often API violations and tend not to manifiest on normal x86 but can occur on platforms such as Xen and some other architectures. When this *does* happen, the driver authors ought (in principle) to fix the bug. We've only had this happen once or twice.

We really ought to have a hardware "whitelist" and "blacklist" on the Wiki so that people can make more informed purchase decisions. Someone mentioned it but I'm not sure if it's there yet...

Xen users,

I am in the process of buying a Xen machine to do testing and see if Xen is
a good choice for our site. I will be deploying version 3, but it won't be
in production for some months.

My question is, has anyone used the Emulex dual channel fc cards in Xen?
Where there any special tricks involved in getting it to work? I've read
some of the other posts on the mailing lists, and some people say to use
Qlogic cards with CLVM, which I haven't used yet.

Hardware specs:

Sun Fire x4200 with:
2 x 254 Opterons
73 x 2 SAS disk
Quad channel ethernet
Emulex PCI-2 2G Dual Channel FC Host card
