A checkpoint reflects the state of a PFS at the time the checkpoint is

created. SnapSure supports the following checkpoint types:

 Read-only checkpoints—Read-only file systems created from a

PFS

 Writeable checkpoints—Read/write file systems created from a

read-only checkpoint

SnapSure can maintain a maximum of 96 read-only checkpoints and 16

writeable checkpoints per PFS, while allowing PFS applications continued

access to real-time data.

Note: Each writeable checkpoint is associated with a read-only

checkpoint, referred to as the baseline checkpoint. Each baseline

checkpoint can have only one associated writeable checkpoint.

Using VNX SnapSure, available on EMC online support, provides more

details.

EMC VNX Virtual Provisioning™ enables organizations to reduce storage

costs by increasing capacity utilization, simplifying storage management,

and reducing application downtime. Virtual Provisioning also helps

companies to reduce power and cooling requirements and reduce

capital expenditures.

Virtual Provisioning provides pool-based storage provisioning by

implementing pool LUNs that can be either thin or thick. Thin LUNs provide

on-demand storage that maximizes the utilization of your storage by

allocating storage only as needed. Thick LUNs provide high performance

and predictable performance for your applications. Both types of LUNs

benefit from the ease-of-use features of pool-based provisioning.

Pools and pool LUNs are the building blocks for advanced data services

such as FAST VP, advanced snapshots, and compression. Pool LUNs also

support a variety of additional features, such as LUN shrink, online

expansion, and user capacity threshold setting.

Virtual Provisioning allows you to expand the capacity of a storage pool

from the Unisphere GUI after disks are physically attached to the system.

VNX systems have the ability to rebalance allocated data elements across

all member drives to use new drives after the pool is expanded. The

rebalance function starts automatically and runs in the background after

an “expand” action. You can monitor the progress of a rebalance

operation from the General tab of the Pool Properties window in

Unisphere, as shown in Figure 8.
