Also any experience in actual perfomance improvement with hardware RAID cards over software RAID. I am intending to run RAID 10. any 3ware made = 9550 card or any Areca made card from the last 3 years for SATA disks. For SCSI, I'm only really using LSI at the moment made by and sold by / as LSI. Most of the branded LSI kit, like what you find in IBM / Dell / HP kit also works fine. - KB ___ Ilugd mailing list Ilugd@lists.linux-delhi.org http://frodo.hserus.net/mailman/listinfo/ilugd

And does RAID status monitoring works fine ? depends on what you mean by fine. You will need to do some parsing in a script and feed that into your monitoring system like nagios yourself. Here is some output from the tw_cli command line client that people use with 3ware cards : # ./tw_cli.x86_64 /c0 show Unit UnitType Status %RCmpl %V/I/M Stripe Size(GB) Cache AVrfy -- u0RAID-1OK - - - 465.651 ON OFF u1RAID-10 OK - - 64K 931.303 ON OFF Port Status Unit SizeBlocksSerial --- p0 OK u0 465.76 GB 976773168 9QM0J6Q9 p1 OK u0 465.76 GB 976773168 9QM0JGPX p2 OK u1 465.76 GB 976773168 9QM0JG5W p3 OK u1 465.76 GB 976773168 9QM0JG63 p4 OK u1 465.76 GB 976773168 9QM0JGNX p5 OK u1 465.76 GB 976773168 9QM0GW98 p6 NOT-PRESENT - - - - p7 NOT-PRESENT - - - - Name OnlineState BBUReady StatusVolt Temp Hours LastCapTest --- bbu On Yes OKOK OK 0 xx-xxx- So that would give you details on everything, including the interface, the volumes under it, the disks and the Battery unit. What you do with that info is upto you :) Make sure you buy a hba that actually does what you need, fits in the machine you want it to work with, and has the ports / setups that you need. - KB ___ Ilugd mailing list Ilugd@lists.linux-delhi.org http://frodo.hserus.net/mailman/listinfo/ilugd
