Two quick vinum/RAID questions: Question #1) Is it possible to create a boot/install floppy that loads vinum? I have 2, 1.2 GB EIDE drives and would like to have them seen as one for the install if this is possible. We are intending to us the DPT PM3334UW/3 - http://www.dpt.com/products/pm3334uw.html - in a FreeBSD server we going to start building next week. The DPT controller typically - what we have done with Linux, NT and Novell installations - creates a RAID stack (0, 0/1, 1, 5, etc.) that is managed by it's BIOS and them serves up the stack to the OS as a single, contiguous drive (ie- RAID0 with 4, 4GB drives; the OS only sees 1, 16GB drive). DPT says that this works the same way for BSD; I have no personal knowledge yet on this point. Question #2) Presuming that DPT will actually perform this way with FreeBSD, am I better off letting the controller handle the RAID stack (my hunch is, "Yes.", for performance reasons) in FreeBSD too, or should I use "vinum". I have no personal "vinum" experience as yet so needed to ask. BTW, the controller will/would be managing 5, 18.2GB UW SCSI drives in a hot-swap RAID5 stack with 64MB ECC EDO RAM. I am going to read through the man pages here in a moment; just wanted to see if someone had some experience doing this as the man pages aren't always the most current data source. Thanks! RAB P.S. BTW, FreeBSD 3.2, 4-CD/ROM set from Walnut Creek and this is an Intel platform. --------------BBC4F7EDDBF1D7BA134B36DF Content-Type: text/x-vcard; charset=us-ascii; name="rbettle.vcf" Content-Transfer-Encoding: 7bit Content-Description: Card for Roy Bettle Content-Disposition: attachment; filename="rbettle.vcf" begin:vcard n:Bettle;Roy tel;work:(949) 452-1203 x-mozilla-html:FALSE url:http://www.criterion-group.com org:Criterion Group, Inc. version:2.1 email;internet:rbettle@criterion-group.com title:President note:Businesses that depend on computers, depend on us. adr;quoted-printable:;;26895 Aliso Creek Road=0D=0ASuite B404;Aliso Viejo;CA;92656;USA fn:Bettle, Roy end:vcard --------------BBC4F7EDDBF1D7BA134B36DF-- To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
