depends on the size of the disks i think. i have a compaq server here(piece of shit) that has 4x36GB scsi drives ~103GB in raid 5 which drops it to ~77GB. if i configured it with hot spare it would drop even more to ~45GB > Is aacraid reliable? We are using Mylex on the VALinux boxes. > Any recommendations for this box, apart from the price? is aacraid same as DAC960 ? i use DAC960 in 1 machine and it runs quite well. only problem is that particular board doesn't support bios boot spec with the current firmware (maybe its been updated since we installed it) and we had to get a custom bios from supermicro to get the system to boot properly with it(not booting from the raid array but booting from the onboard adaptec scsi) if i was building a SCSI raid system i would be using DAC960. and i wouldn't personally use anything from dell unless it was free. i dispise that company. their lackluster support of linux is pathetic too. i wouldnt let a tech from any company touch my system with their on site service. i had a compaq on site visit once, after spending 30mins with tech support trying to figure out how to setup a DL380 on rails in my APC rack cabinet, they send a guy out because nobody knows how to do it and the guy spends 20 minutes and fails only to see that the rack kit is incompadible with my DL380(generation1). rather stick with stuff i maintain myself. nate
