SolarisZfs

ZFS is an intelligent filesystem with in-built virtual disk management and data protection.

ZFS can manage a variety of storage resources (whole disks, partitions, files). Unlike traditional approaches where each filesystem is a static allocation of physical storage, ZFS filesystem storage is allocated as it is used. ZFS manages usage quotas as filesystem size limit. Thus ZFS favours the creation of many individual filesystems.

Configuration

The configuration employed here, limits the number of disks in each storage pool so that, in the event of x4500 hardware failure, it remains feasible to install each storage pool into alternate hardware.

The disks are grouped into raid sets for protection from disk failure.
