Hi, I am planning to install CentOS 6.4 on Dell R720 which has hardware raid card and 6 hard disk slots available. I have planned with the below set up :- *2 Hard disks configured in RAID 1 for installing OS * *4 Hard disks configured in RAID 10 for data drive.* Please suggest and recommend if the above approach is correct and let me know if i am missing anything which is crucial to set up a production server. This server will host MySQL DB server. Regards, Kaushal

For a base OS + MySQL server, a 4GB SATA Disk on Module (DoM) may be sufficient.> * > *4 Hard disks configured in RAID 10 for data drive.* >Again, hopefully, you have sized these disks for sufficient space for the DB files, presuming you will mount this device on /var/lib/mysql.> Please suggest and recommend if the above approach is correct and let me > know if i am missing anything which is crucial to set up a production > server. This server will host MySQL DB server.You may want to put /tmp, /var/tmp/, /var/log on separate partitions - 1G, 1G, 3G, respectively. You can "steal" this kind of space by creating a LV on your RAID10 device and carving it up as above with the rest for your MySQL files. HTH, -- Arun Khan

This server will host MySQL DB server.Is there any particular reason why you want to create two RAIDs? Creating one 6 Disk RAID-10 would give you better random IOPS which is useful for a DB System. You can still create two independent virtual disks in that case or use independent partitions/LVM volumes to separate OS from Data. Regards, Dennis
