* GROUP DESCRIPTION
* -----------------

One of the most challenging aspect of any software solution is to manage

the storage effectively.

Our group, Automatic Storage Management (aka ASM), is responsible for

building highly available, scalable, and efficient tools to solve

customers' storage problems. ASM is the central part of the Oracle

Database's storage strategy. While it is versatile enough to run with

any physical storage backend, ASM is also the key storage solution

that enables the database to run in engineered systems such

as the Exadata Database Machine and the Oracle Database Appliance (ODA).

Some of the salient features of the ASM that makes it a ground breaking product are:

* File-based mirroring capabilities

This allows the user to use the same storage pool and have different

mirroring on a file by file basis. This maximizes storage

utilization while providing high availability for data that require

extra protection.

* Dynamic online load re-distribution when storage pool changes.

ASM allocates files in a balanced fashion. Thus, no data movement

is required to maintain a balanced I/O load in a static storage

configuration. If the storage configuration changes, data

re-distribution involves minimal data movement, unlike other

prevailing solutions. ASM rebalance occurs in the background while

databases and dependent applications remain online.

* Consolidated storage pools

Allows users to consolidate their storage into a single clustered

pool of up to 10,000 disks and consisting of up to 1 million files.

* Improved data availability

ASM takes proactive actions where applicable.

The key algorithms used in ASM are patented and there is still lot of

research that needs to be done to improve data availability with

minimal impact to the application in light of various kinds of storage

failures/corruptions.
