Addressing data storage performance with storage monitoring tools

Enterprise data storage performance bottlenecks that can clog disk drives, controllers and the ports into arrays can be addressed by a mix of storage-related tools. Storage administrators can address performance bottlenecks by turning to one or more of the following options:

1. Application tools that are built into applications. These include Microsoft Corp.'s Exchange Server and SQL Server and Oracle Corp.'s database servers.

2. Operating system tools. In a Windows environment, Perfmon can be used, while iostat or sar can be used in a Unix/Linux environment.

3. Element managers for the storage arrays and the switches.

4. Storage resource management (SRM) software, such as:

5. SAN monitoring applications, including:

6. Specialized storage performance monitoring tools from vendors such as Akorri, Tek-Tools and Virtual Instruments Corp.

These tools generally work by sending commands to the element managers, talking to a storage device's APIs or command-line interfaces. They can also work by using Simple Network Management Protocol (SNMP) and the Storage Management Initiative Specification (SMI-S) put out by the Storage Networking Industry Association (SNIA).
