I use HP Netserver LH6000 in this configuration:

5 CPU Xeon550/1MB Netraid (integrated megaraid.o) ee100 (integrated) 3C905 8 x 18/36 GByte SCSI/hotswap

For backup purposes I would like to use cheap IDE-harddisks. The requirements for this config are:

- no problem for XEN if one IDE-drive get a physical error - hotswap (no downtime for HD replacement)

I think the only way to achieve this is to use IDE raid with one IDE-channel per harddrive and I know only about 3ware controllers with this features.

Is there a driver for 3ware or alternative approaches?

If there's a driver for Linux then it can probably be ported to Xen without too much pain.

Is there a porting howto or other help?

the .config 2.4.22 to 2.4.24 contains the CONFIG_BLK_DEV_3W_XXXX_RAID # # SCSI low-level drivers # CONFIG_BLK_DEV_3W_XXXX_RAID=y # CONFIG_SCSI_7000FASST is not set # CONFIG_SCSI_ACARD is not set # CONFIG_SCSI_AHA152X is not set # CONFIG_SCSI_AHA1542 is not set # CONFIG_SCSI_AHA1740 is not set # CONFIG_SCSI_AACRAID is not set CONFIG_SCSI_AIC7XXX=y
