MILAN0 Posted December 10, 2008 Share Posted December 10, 2008 Hi everybody. Is here any guys successfully started SCSI interface to host SCSI drivres. I'm interested to start PCIe x4 on this http://www.attotech.com/ultra5D.html Link to comment https://www.insanelymac.com/forum/topic/140413-scsi-devices/ Share on other sites More sharing options...
vladthebad Posted December 11, 2008 Share Posted December 11, 2008 I've been running SCSI stuff for what seems like forever. My current SCSI card is an LSI PCI-X133 dual channel U320 card... using the LSI 53c1030 chip OSX has built in drivers for most of the recent LSI stuff.... Xserve uses LSI 1068e SAS controller, the PCI-X U320 card available for Xserve uses 53c1030 chip, the apple Fiberchannel cards use LSI fiberchannel chips... and LSI was nice enough to make fiberchannel, SCSI, SAS/SATA chips ALL run the same driver family... they all use the FusionMPT "architecture"... and the same extension. AppleLSIFusionMPT.kext for parallel SCSI, anything using the 53c1030 chip or other related FusionMPT chip from LSI should just work. If it doesn't, add it to the extension. Shows up in system profiler just fine, runs great, I've just got a bunch of 18 gig 10k RPM drives and 4 36 gig 10k RPM drives... all U160 drives.... best I've gotten is about 200mb/sec when using a real PCI-X133 slot. with a 32 bit, 33mhz normal bog standard PCI slot, I can get a hair above 100mb/sec on most boards when running RAID0 As far as ATTO cards... they also use LSI chips on them, but have different drivers as I understand it. If I was in the market to buy a new parallel SCSI card, I'd hit up ebay and buy an LSI card that was yanked out of some HP or dell or IBM most likely. if I was buying a new SAS card.... I'd do the same... Unless this is for a production environment.... if its for a production environment.... what are you doing running it on a hack? heh..... Production environment, I'd buy an LSI card and stick it in your Xserve or mac pro. Oh, remember to terminate your SCSI chains properly and to not have SCSI ID conflicts! Conflicts or improper termination or {censored} cables can and WILL cause your machine to not boot. And no, I don't know how to force a SCSI bus rescan... otherwise I'd most likely have gotten at least 1 more SCSI card working so I could use my SCSI CD burner. (Works great until you eject a disk... heh) Link to comment https://www.insanelymac.com/forum/topic/140413-scsi-devices/#findComment-994806 Share on other sites More sharing options...

djfremen Posted March 12, 2009 Share Posted March 12, 2009 Hi everybody. Is here any guys successfully started SCSI interface to host SCSI drivres. I'm interested to start PCIe x4 on this http://www.attotech.com/ultra5D.html I have this card. I tried it in my GA-EP45-DSR3 and it refuses to boot. Works fine in my Mac Pro. A pity, I was sure it was going to work. Link to comment https://www.insanelymac.com/forum/topic/140413-scsi-devices/#findComment-1105613 Share on other sites More sharing options...
