Thin Provisioning and Thin Provisioning Z
Thin Provisioning and Thin Provisioning Z enables you to use to create virtual volumes to allocate
capacity to a virtual host (server) in excess of the available physical disk capacity. The virtual
volumes create a storage pool to store data. Each time you increase capacity, you need to prepare
only a minimum number of data drives and do not need to stop the system. Initial installation costs,
electricity costs, and air conditioning costs can therefore be reduced, and effective use can be
made of storage resources because only the capacity in actual use is needed from the physical
capacity. Thin Provisioning levels the loads on storage pools, so the need to consider the physical
configuration for performance optimization purposes when planning allocation of volumes is
removed. This also helps reduce the storage-performance design workload.
Smart Tiers and Smart Tiers Z
Smart Tiers and Smart Tiers Z convert the storage pool of a virtual volume to a tiered structure.
Stored data is automatically allocated among the different types o storage to create storage tiers.
The tiers include SSDs, SAS drives, external volumes or other types of disks. Data that is accessed
more frequently is moved to high-speed storage tiers, and data that is accessed less frequently is
moved to low-cost storage tiers. As a result, both storage performance and cost performance
improve.
Resource Partition
Resource Partition defines one storage system as multiple virtual private storage systems. This
enables you to configure a storage system across multiple businesses and divisions as multiple
individual storage systems. In this way, when load is concentrated on a specific business, other
businesses suffer no impact. In addition, you can limit access by assigning administrators to
individual virtual private storage systems to prevent data damage or illegal access caused by
external attacks.
Virtual LUN and Virtual LVI
Virtual LUN and Virtual LVI provides a way to create logical volumes of any size by partitioning
or combining fixed-size logical volumes (FVs) within a parity group. These functions also enables
you to create logical volumes according to the data capacity that is required. For example, you
can create a logical volume for each file to reduce data drive access contention, or create a
small-capacity logical volume to suit a command device.
LUN Manager
LUN Manager provides a way to set data input and output paths between open servers (such as
UNIX servers or PC servers) and logical volumes. LUN Manager enables you to add data input
and output paths to the storage system when you add a host or data drive. You can also protect
data from unauthorized access by limiting the logical volumes that are accessible from a host.
Data Retention and Volume Retention
Data Retention and Volume Retention enable you to control the access to logical volumes. By
default, all hosts are permitted to read and write all volumes. Consequently, if a user makes a
mistake when writing data to a volume, data can damaged or unexpectedly deleted (or confidential
data might be leaked due to unauthorized access). By using Data Retention and Volume Retention,
you can set the access attribute to protect volumes from access from unauthorized hosts.
