Master Note For Automatic Storage Management (ASM) For Operating System (OS) Administrators
All Platforms
General Operating System (OS) Requirements:
Note: Keeping the Operating System (OS) kernel current helps stabilize the system. Production systems should never run an out dated Operating System (OS) kernel version. As a best practice, Oracle recommends the Operating System (OS) kernel version be maintained to within 6 months of current. Please contact the Operating System (OS) vendor directly for more information, risk exposure, and patching recommendations.

Automatic Storage Management (ASM) Configuration:
Note:
Performance problems could occur on diskgroups having disks with an uneven size. Oracle recommends having disks with a uniform size and same physical characteristics (same vendor, same model, same speed, etc.), to guarantee ASM rebalance operation works as expected and to provide a good throughput. Disks in a given diskgroup should have similar size and performance characteristics. ASM load balances file activity by uniformly distributing file extents across all disks in a diskgroup. For this technique to be effective it is important that the disks used in a disk group be of similar performance characteristics.

Storage Multipathing:
Note:
Oracle Corporation does not certify or qualify multipathing tools. Although Oracle Automatic Storage Management (ASM) does not provide multipathing capabilities, Oracle Automatic Storage Management (ASM) does leverage multipathing tools, as long as the path or device produces a successful return code from an fstat system call.

Note: Additional needed information for Linux Platforms, if ASMLIB is being used.
Note: For RHEL6, Oracle will only provide ASMLib software and updates when configured with a kernel distributed by Oracle. Oracle will not provide ASMLib packages for kernels distributed by Red Hat as part of RHEL6...ASMLib usage will require replacing any Red Hat kernel with a kernel provided by Oracle.
