Yes, it's nice to see that's coming; And that FC & SAS are "the same". But I'm at S10U3 right now. > Multipathing support tends to depend on table entries and manufacturer-specifi > c information if the array isn't active/active.

I have experience making S10 MPXIO work with 3rd-party arrays (HDS); This VTrak model can be configured to do active/active in a mode which looks like what Sun calls "symmetric". But my experience tells me that mileage may vary. As I haven't bought anything yet, I was hoping to hear from someone who has already tried it. > > - VTrak can take SATA disks; ST-2500 lists only 15k rpm SAS disks. > I think that might be a different model. Understood. Perhaps I'm odd, but the fact that the same VTrak model can take either SAS or SATA disks, depending on needs, is a good feature. Our customers are researchers, and such flexibility is a plus. Too bad it's so hard to get pricing on the ST-2500 unit. Here's one reference I found which gives a idea: http://www.storageperformance.org/results/b00022_Sun-ST2540-Mirroring_SPC2_full -disclosure.pdf Thanks for the note, Marion _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
