Components of Thin Image

Thin Image typically consists of several components, including pairs, groups, and software applications. Thin Image requires Dynamic Provisioning, which is used to access data for open-system servers such as UNIX and PC servers in a pool volume through a virtual volume.

Thin Image components:

• Thin Image pairs (clone and snapshot pairs).
• Volume related components (P-VOL, S-VOL, and pools)
• Snapshot tree related components (root volume, node volumes, and leaf volumes)

Groups:

• Consistency groups
• Snapshot groups

Software applications for VSP family storage systems:

• Thin Image
• Dynamic Provisioning (HDP)
• Command Control Interface (CCI)

  You can run CCI commands to perform Thin Image tasks (see Pair tasks using CCI or Device Manager - Storage Navigator).

Parent Topic

• Overview of Thin Image

  With Thin Image (HTI), you can perform cost-effective replication by storing the differential data between primary volumes (P-VOLs) and secondary volumes (S-VOLs) of virtual volumes (V-VOLs). You can also copy data of an entire volume, instead of copying just the differential data, to a volume. By copying the entire volume, you can expect a higher performance than by just storing the differential data.

Child Topics

• Thin Image pairs

  This table describes Thin Image pairs.

• Volume components

  To create Thin Image pairs, the following volumes are required.

• Snapshot tree components

  A snapshot tree contains the following volumes.

• Consistency and snapshot groups

  Consistency groups and snapshot groups are groups of pairs for which you can simultaneously perform pair tasks on all pairs within the group.

• Snapshot Clones
• Snapshot trees and cascaded pairs

  Snapshot trees are Thin Image pair configurations where snapshot data is stored.

• Creating cascaded pairs
• VSP family software applications for Thin Image

  A Thin Image installation typically includes the Thin Image software, Dynamic Provisioning software, and CCI.
