Linux对哪些SATA RAID控制器支持的比较好呢

HsiehP

　　一个基于Ｂ／Ｓ模式的国库集中支付试点项目。数据库是安装在一台跑Win2003的Oracle 10G，这暂时不去动它。应用服务是使用Ｊ２ＥＥ开发出来的，这就有条件摆脱微软的限制了。已经说服了一把手，同意尝试使用开源软件，初步打算用Ｄｅｂｉａｎ。
　　考虑到国库支付局的统管会计人数，加上各乡镇财政所，最大并发联接不会超过５０个。由于应用服务器和数据库是分离的，因此考虑使用SATA硬盘跑RAID 0模式就够了。
　　现在的问题是Linux对哪些ＳＡＴＡ　ＲＡＩＤ芯片支持的比较彻底，好根据这一信息，确定具体的ＰＣ服务器型号，报采购中心。

本人没经验，想到的：看一下内核支持那阵列卡，选个内核支持的。

NVidia /intel /ATi /Via 的BIOS RAID支持都是完美的
RAID卡里 LSI Logic MegaRAID Driver 支持好些

别的不说 对intel和LSI的 megaraid支持相当的糟糕。
应该说linux对fakeraid的支持都很糟糕
建议用硬raid卡
不要相信bios raid和便宜的sata raid卡，都是fakeraid的

dennis175

使用硬RAID卡最好不要用RAID 0最好用RAID 1可以避免重装系统

其人，没有实际用过的，，只是引用别人的而已。。。。

NV的C61和MPC78我就在用。ATI的R780/R790/R800的也有在用的。觉对不比硬RAID差。

udevinfo -a -p /sys/class/scsi_device/0\:2\:0\:0

Udevinfo starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.
