Your answers to my "questions about production use" mail are very good. I try to go the way with XEN. 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? Manni

The hassle required to port SCSI drivers varies widely.> the .config 2.4.22 to 2.4.24 contains the CONFIG_BLK_DEV_3W_XXXX_RAIDLooking at this one it will almost certainly be very easy. The ioctl() function is the only thing that looks tricky, but it can probably be commented out. We can take a look at this when we have some spare cycles -- currently we''re trying to get a 1.2 release CD out the door! -- Keir ------------------------------------------------------- The SF.Net email is sponsored by EclipseCon 2004 Premiere Conference on Open Tools Development and Integration See the breadth of Eclipse activity.
