Dave Wanna sleep soundly? Get yourself some manly, enterprise-class external storage gear - DEC->COMPAQ->HP (maybe RonCo's next?) StorageWorks. Hiding your HDs inside the CPU box just isn't worth the pain. You can pick up discontinued, but new, gear and start your very own SAN for under $5K with HSG80 controllers. If you just want one or two boxes hanging off the storage, go with something like the HSZ70's (copper SCSI cables 'stead of fiber) - that'll set you back about $2K. You'll have fast, reliable RAID5*, redundant controllers & power supplies, online hot spares, and pretty blinky lights for about the cost of one high-end gaming box. Buy yourself a halfway-decent UPS at the same time to protect the investment. I'm in love with the "EMA12000", but the fibrechannel HBA (grandiose disk controller) is pretty pricey. Go with the HSZ70 and you can use a common-as-dirt Adaptec SCSI card. When a drive fails, one of your green blinky-blights goes amber, and one of your hot-spares jumps right in. You also get a nice idiot-tolerant audible alarm in case you don't regularly gaze at the blinkylights. I've got, most likely, every incarnation of StorageWorks dating back to VAX/VMS and 1.2GB 16-bit SCSI drives (RZ-26, fwiw) running in the room next to me. The stuff is solid. I know a great vendor, if anyone cares. ;-) Surreal You'll develop an unhealthy emotional attachment to StorageWorks... * "adaptive RAID 3+5", whatever the fuck that means. Looks and tastes like RAID 5.
Ok, this is what I don't get - if you're using Software RAID on Linux, then what do you do when your boot drive dies? I'm looking for hardware RAID because I like the idea of a quick hotswap. I don't see how you could do that with software. -dave _______________________________________________ Dailydave mailing list Dailydave () lists immunitysec com https://lists.immunitysec.com/mailman/listinfo/dailydave
