Determined chunk size (*3) 21MB 336MB
*1: Up to 256 pools can be created. When the maximum installation number of drives of a model is 512 or less, the maximum number of
pools is half the maximum installation number of drives.
The maximum pool number is the maximum total number of TPPs and Flexible Tier Sub Pools (FTSPs) that can be created in the
ETERNUS DX.
*2: The maximum pool capacity is specified when "Enable" is selected for the Thin Provisioning function. Refer to "Thin Provisioning
Configuration" (page 120) for details.
The maximum pool capacity is the maximum total capacity for TPPs and Flexible Tier Pools (FTRPs) that can be created in the ETERNUS
DX.
*3: Chunk size is a physical capacity that is assigned to virtual logical volumes created in TPPs and FTRPs when a write occurs from the host.
The chunk size is determined according to the "Maximum Pool Capacity" of the ETERNUS AF/DX when a new TPP is created.
There are two methods to create a TPP; automatic drive selection and manual drive selection.
■
Automatically Selecting Drives to Create TPPs
To create a new TPP automatically, select Drive Type and RAID Level, and input TPP capacity. The Controlling CM
of the RAID groups that configure the TPP is determined automatically.
Caution
When drives that satisfy all the following conditions are installed in the ETERNUS DX, select the drives
manually.
• The drive types are the same
• The drive capacities are the same
• The drive sector format (Advanced Format (AF) compliant or non-AF-compliant) is different
