https://community.hpe.com/t5/server-management-remote-server/raid-migration-on-hp-smart-array-6402-128-controllers-card/m-p/3977997#M2681 Hi, There,<BR />We are running MS SQL database on HP Proliant G4 380 With RAID 1 Configuration. Currently we have 2 set of RAID 1, One for OS drive and another for Database drive. The 2 HDD for database drive are 15K SCSI UTRA320.<BR />However we are still facing Disk I/O performance issue, so we plan to migrate to RAID 1O configuration which in turn will have 4 HDD to support the database read and Write.<BR />I was told that there is a way of RAID migration from RAID 1 to RAID 10 with my database continue on line and without any harm, but myself do hv any idea on this, and I need carry out this activity on production server directly, I will be very apprecitated if any one can give some information on this.<BR /><BR />Best regards<BR />Shermaine <BR /> Tue, 10 Apr 2007 04:39:10 GMT shermaine_1 2007-04-10T04:39:10Z https://community.hpe.com/t5/server-management-remote-server/raid-migration-on-hp-smart-array-6402-128-controllers-card/m-p/3977997#M2681 Hi, There,<BR />We are running MS SQL database on HP Proliant G4 380 With RAID 1 Configuration.
