Adaptec SCSI RAID 2100S

Advantages: online capacity expansion, deals with hard disc problems better
Disadvantages: slow compared to software RAID

...recommend upgrading to current firmware and 2.16 storcon utl (both are on www.intel.com. There is a linux version of the 2.16 storcon, but it was hard to find!) With initial installation on a Gigabyte GA7 motherboard and Adaptec 2940AU SCSI controller, the problems with onboard intel BIOS / adaptec 2940AU and mobo BIOS reared it's ugly head. I could not for the life of me with all the PCI juggling, IRQ remapping and BIOS remapping options get it to boot with a Adaptec SCSI card and Intel RAID card. I asked a friend about his setup, and he had no problems (he was running a Intel serverboard with his SRCS14L) My problem was solved by removing SCSI from system completely and migrating to IDE bootup drives (which was such a pain on linux!) Current drivers are 2.05 which are included since the 2.4.19 kernel. As with all RAID controllers... Read review

...Finally, just when I was begining to give up on ever attaching my SCSI drive to my system, along came the answer to my prayers.

Everything is supplied and with easy to follow directions. It is not cheap though, expect to pay about $50 ($90) for it but compared with a SCSI card & cables it probably works out the same and is definately 100% less hastle than trying to configure an already stuffed full to the brim machine. It's got my vote.... Read review

...of my first ever submission to Ciao) all of which require a SCSI controller in order to connect them to your PC! So as well as discussing Adaptec’s excellent card I will also try and give a simple introduction to SCSI what it is, its pros and cons and why you might want to use it. A SCSI card is possibly one of the least sexy devices you can plug into your PC. However, it is one of your more useful options as installing it opens up a huge range of possibilities. SCSI stands for "Small Computer System Interface" and is pronounced "scuzzy" and is a system for connecting things to your pc, things like hard drives, scanners and cd writers, devices that need to be able to shift hefty amounts of data about quickly. A while back SCSI walked all over IDE in terms of performance but cost a packet. Not only were SCSI devices vastly more... Read review
