According to the 3ware Web site, the 7506 uses a different firmware, driver, and utility series than the 7500 models. I would not _assume_ that it would work. Although there is someone who recently started working on the FreeBSD driver for 3ware cards (sorry, can not remember the name), 3ware does not support FreeBSD in any way. I have a 7500-8 card and I have had firmware issues with it. It turns out that I can not use the card for RAID1+0, which is what you said you wanted, because the array can not initialize after a drive failure in RAID1+0 mode. I had to reconfigure my array as RAID-5. That was not fun but it does work well in RAID-5 mode. That being said, I know there are other FreeBSD users who have successfully used a 7500 card for RAID1+0. It depends on what hardware revision you get. I would strongly encourage you to buy the 7506 from a vendor that will allow you to easily return it should it not work under FreeBSD for you. -- Glenn Johnson USDA, ARS, SRRC Phone: (504) 286-4252 New Orleans, LA 70124 e-mail: gjohnson@srrc.ars.usda.gov
