I have several customers that are using EMC, and other non-IBM storage arrays. > The IBM documentation I can find says that certain IBM and Hitachi disks are > supported.

If you're talking about FICON attached ECKD type storage, yes, it tends to be. > Presentations on zseries SCSI over FCP > often say that 'other disks may work but are not supported' . Those are most likely presentations given by IBM employees. Of course they're not going to certify and support other manufacturer's products. The one exception is if you hook them up to a SAN Volume Controller. They support the mainframe-facing interface and make things work. > I would like to > try out SCSI over FCP point-to-point Please, don't. Attach your FCP adapter to a SAN fabric switch, not point to point. A number of the tools that have been developed to discover and configure SCSI won't work because they depend on the features a switch provides to make that happen. I'm not saying you can't get it to work. I'm saying it will be far more painful than necessary. > with some some disks which have been used > with a Sun unix server - specifically Sun Storedge 3510FC in a JBOD > configuration. Hmm. When I look at http://docs.sun.com/source/816-7300-15/appb_jbod.html, there seem to be a lot of configurations that aren't supported. This piece of hardware may not be your best choice, even if it's no additional cost to use. >When I activate the channel there is a 'sequence time-out'.
