Chapter 3
Setup
This chapter describes the required settings for operation of the ETERNUS DX Disk storage system and provides
notes for setting up each function of the ETERNUS DX Disk storage system. Note that the Thin Provisioning
function cannot be used for a single-controller type.
3.1
Thin Provisioning Setup
The Thin Provisioning function virtualizes and allocates storage capacity. This reduces physical storage
capacity and unused capacity can be used more efficiently.
The user can start operation of the ETERNUS DX Disk storage system with a small disk capacity by allocating
large virtual disks to the server. Physical disks can be added according to the required capacity without
affecting the server.
The Thin Provisioning balancing function can be used to balance the physical allocation capacity of a Thin
Provisioning Volume (TPV) among RAID groups and to distribute I/O access for the TPV to the RAID groups in
the pool.
In addition, the Thin Provisioning function can be used more efficiently by using the Zero Reclamation
function. The Zero Reclamation function releases physical areas with all zero bits.
To use the Thin Provisioning function, register the Thin Provisioning Feature License in the ETERNUS DX Disk
storage system and set up the Thin Provisioning function.
3.1.1
Registering the Thin Provisioning Feature License
■
For the EMEA&I region
After the Thin Provisioning Feature License is purchased, it is activated by registering a Thin Provisioning
Feature license key in the ETERNUS DX Disk storage system.
When purchasing the Thin Provisioning Feature, a Transaction Authentication Number (TAN) and the URL of
the web-site from which the license key may be obtained are notified by e-mail.
■
For regions other than EMEA&I
When the Thin Provisioning Feature License is purchased separately, register the Thin Provisioning Feature
License in the ETERNUS DX Disk storage system.
For details on how to register the license, refer to the "Feature activation licenses" document that is provided
with the Thin Provisioning Feature License.
The Thin Provisioning Feature License is a unique license to each ETERNUS DX Disk storage system. This
license cannot be registered in other ETERNUS DX Disk storage systems.
