• SVM : The Solaris Volume Manager provides the ability to create devices from disk slices that
provide optional data striping (RAID 0), mirroring (RAID 1), parity disks (RAID 5) and Software
Partitions (SoftParts) for enhanced performance, flexibility and availability. SVM is supported on most
Solaris versions today. If it is available on your system it will be automatically included on the SBAdmin
boot media even if you are not using it. This allows you to implement SVM during the install process if
you are not already doing so, creation of new meta-devices or migration of existing filesystems to SVM.
Devices created by SVM are also referred to as “meta-devices” as referred to throughout this
document. Other references to these devices may include MDs, multi-disks or meta-devices. Meta disk
names are in the format “dN”, where N is a number starting with 0 and incremented for each meta-
device.
• ZFS : Solaris 10, release 6/06 and later include ZFS, an easy-to-use, powerful and flexible way of
partitioning your disks into dynamically expandable filesystems and extensible raw volumes. ZFS Pools
are created from disk slices, and then ZFS Filesystems and ZFS Volumes are created within the pool.
If available on the system, ZFS support will be included on the SBAdmin boot media even if it is not
currently in use, allowing the creation of new ZFS pools, filesystems and volumes or the migration of
existing filesystems to ZFS.
• Filesystems : When not using ZFS, most filesystems in Solaris are created within a disk slice and
have a type of UFS (Universal Filesystem). Other supported filesystems include UDFS and PCFS.
PCFS filesystems typically reside in a disk partition and typically contain DOS data. PCFS is also used
on many for the /boot filesystem, used to configure the system to boot from a hard disk.
