The RAID5 is *really* quite fast compared to the older 8000 series 3ware. The drives are the same as before as is the rest of the hardware (see previous postings). Just the raid card has changed. FCIII=Fedora 3. The tests in each case was done with the OS on a separate drive and the /mnt partition one big partition off the raid controller. -------Sequential Output-------- ---Sequential Input-- --Random-- -Per Char- --Block--- -Rewrite-- -Per Char- --Block--- --Seeks--- Machine MB K/sec %CPU K/sec %CPU K/sec %CPU K/sec %CPU K/sec %CPU /sec %CPU twe 2000 33789 25.8 34065 8.3 14038 3.8 47484 44.6 67316 9.5 2873.7 5.7 FCIII 2000 28073 62.0 22391 4.3 12189 2.0 17577 35.5 102132 5.5 1853.7 2.5 ARECA 2000 67648 52.0 63716 17.1 32715 8.5 59734 56.1 76906 11.1 5686.4 11.3 3000 72200 55.7 64210 17.0 32635 8.5 58834 55.5 79055 11.2 329.9 0.9 PostMark v1.5 : 3/27/01 pm>set size 300 100000 pm>set transactions 400000 pm>set location /mnt pm>run Creating files...Done Performing transactions..........Done Deleting files...Done Time: 1287 seconds total 1287 seconds of transactions (310 per second) Files: 200107 created (155 per second) Creation alone: 500 files (500 per second) Mixed with transactions: 199607 files (155 per second) 199905 read (155 per second) 199384 appended (154 per second) 200107 deleted (155 per second) Deletion alone: 889 files (889 per second) Mixed with transactions: 199218 files (154 per second) Data: 12715.55 megabytes read (9.88 megabytes per second) 12728.92 megabytes written (9.89 megabytes per second) pm> The card has source code drivers for FreeBSD 4 and 5 available (i386 and amd64 at ftp.areca.com.tw) on their FTP site as well as a binary cli and http app that allows you to monitor and configure all aspects of the card. The drive shows up as a scsi device so a user can use sysinstall to fdisk / disklabel it. Compiled and loaded the drivers via kld and arcmsr0: mem 0xf9000000-0xf9000fff irq 18 at device 14.0 on pci2. I configured the RAID5 array from the web and a camcontrol rescan all shows da0 at arcmsr0 bus 0 target 0 lun 0 da0: Fixed Direct Access SCSI-3 device da0: 166.666MB/s transfers (83.333MHz, offset 32, 16bit), Tagged Queueing Enabled da0: 715255MB (1464843264 512 byte sectors: 255H 63S/T 91182C) I havent really brutalized the card and drivers yet, but running 2 dozen bonnie -s 200 -d & in the background does not lock up the machine, and despite all the io going on, the machine is still fairly responsive It would be really great to see support for this card as part of FreeBSD. The source code seems to imply a BSD'ish header, so perhaps this will be possible ---Mike
