The 3ware uses the 3w_9xxx (in sarge kernels) while the Areca uses arcmsr (not in sarge). With the arcmsr driver, I grabbed the source from the Areca website and built, with the kernel headers installed, like so: make -C /lib/modules/$(uname -r)/build M=${PWD} modules Then copy the module into the appropriate place: /lib/modules/$(uname -r)/kernel/drivers/... and run update-modules. I *believe* the arcmsr driver is now in the upstream kernel (and so in the latest Debian sid kernels). > Any experience with the 9550 series?

I believe you can have the disks in pass-thru (JBOD) mode but have never used it in this way. When you have an array defined, you only get the array. The command line tools and the web-server admin/monitor all work fine for both tools. > We need a SATA RAID solution but we want the drivers to be in the > current sarge release.

Go for 3ware if you don't want the admin overhead of maintaining the modules. They're a little cheaper and work well enough. One difference to note: with the version of the Areca driver I have, there are no syslog/kernel messages when disks die or are removed. Hopefully this has changed in later versions. The alarm is quite loud though. ;-) Ronny -- Ronny Adsetts Technical Director Amazing Internet Ltd, London t: +44 20 8607 9535 f: +44 20 8607 9536 w: www.amazinginternet.com
