isilon disk pools

Isilon disk pools are a way of grouping and managing the physical disks in an Isilon storage cluster. Each disk pool is a collection of physical disks that are used to store data and metadata for the Isilon cluster. The disks within a disk pool can be of different sizes and speeds, but they must all be of the same type (for example, SAS or SATA).

Disk pools are used to provide performance and capacity isolation between different types of data on an Isilon cluster. By creating separate disk pools for different types of data (such as home directories, databases, or virtual machine images), you can allocate different amounts of disk space and I/O resources to each pool, ensuring that each type of data gets the appropriate level of performance and capacity.

In addition to performance and capacity isolation, disk pools also provide several other benefits, including simplified management of disk-related tasks (such as adding or removing disks), improved reliability through the use of redundancy and data protection mechanisms, and support for tiered storage architectures (where different types of data are stored on different tiers of storage media, such as flash or disk).

Overall, Isilon disk pools are a powerful tool for managing the physical disks in an Isilon storage cluster, and can help you optimize performance, capacity, and reliability for different types of data.
