Looking for experiences of using ASM vs Hardware RAID. Currently have a database running on internal filesystem disks (no ASM, just standard ext3). The database is outgrowing the internal disks, so the next step is to attach an external array.
Can anyone recommend a good strategy?
Options under consideration:
1) Array with raw disks attached and ASM 2) Array with hardware raid and filesystem (no ASM) 3) Some combination of hardware raid and ASM
Also we're looking at the HP range of storage (MSA and EVA). Any recommendations or warnings about those would be good too. The storage will be dedicated to the database and flash recovery area.
Any advice is appreciated.
Thanks
Ray
