Increasing the Veritas Data Deduplication storage to 2.4 PiB

Starting with version 8.1, you can configure up to 2.4 PiB of storage for the Veritas Data Deduplication server. You can configure two instances of Veritas Data Deduplication with 1.2 PiB storage each for a total of 2.4 PiB of storage. If you plan to increase the storage, ensure that the appliance has sufficient system memory.

You require 0.5 GB of system memory for every 1 TB of storage when you configure the Veritas Data Deduplication server. If you want to configure 1.2 PiB storage, you require 768 GB of system memory as additional system memory kit can be purchased in 386 GB increments. If there is insufficient system memory, the Veritas Data Deduplication configuration fails. Ensure that you install additional system memory as per your requirements before you configure additional storage for the Veritas Data Deduplication server.

If you don't plan to provision storage for Veritas Data Deduplication, you don't require any additional system memory.

When enabled, the Predictive and Sampling (PS) cache feature provides support for Veritas Data Deduplication pools up to 2.478 PiB (approximately) of storage. If you have upgraded to Access Appliance 8.4 from an earlier version, the previously configured Veritas Data Deduplication instances continue to use the Finger Print (FP) cache mechanism. In order to leverage the 2.478 PiB storage, the type of cache mechanism of the Veritas Data Deduplication container instance should be converted to PS cache, Veritas strongly recommends that the operation be performed under the supervision of Veritas Technical Support.
