storage area network (SAN)
An architecture in which the storage elements are connected to each other and to a server
that is the access point for all systems that use the
SAN to store data.
storage domain
A secure container that holds a subset of the system’s total storage resources. Multiple
storage domains can be created to securely partition the system’s total set of storage
resources. This enables you to organize multiple departments or applications into a single
storage management infrastructure.
storage pool
A container that groups physical disk capacity (abstracted as virtual disks in the
browser interface) into a logical pool of available storage capacity. A storage pool’s
characteristics are defined by a storage profile. You can create multiple storage pools
to segregate storage capacity for use in various types of applications (for example,
high throughput and online transaction-processing applications).
storage profile
A defined set of storage performance characteristics such as RAID level, segment size,
dedicated hot-spare, and virtualization strategy. You can choose a predefined profile
suitable for the application that is using the storage, or you can create a custom profile.
storage tray
An enclosure containing disks. A tray with dual RAID controllers is called a
controller tray; a tray without controllers is called an expansion tray.
stripe size
The number of blocks in a stripe. A striped array’s stripe size is the stripe depth
multiplied by the number of member extents. A parity RAID array’s stripe size is the
stripe depth multiplied by one less than the number of member extents. See also
striping.
striping
Short for data striping; also known as RAID Level 0 or RAID 0. A mapping technique in
which fixed-size consecutive ranges of virtual disk data addresses are mapped to
successive array members in a cyclic pattern. (SNIA).
T
target
The system component that receives a SCSI I/O command. (SNIA).
