Features and benefits include:
Data compression
– Transparent in-line data compression can store more data in less space, reducing the
amount of storage you need to purchase and maintain.
– Reduces the time and bandwidth required to replicate data during volume SnapMirror
transfers.
Deduplication
– Runs block-level data deduplication on NearStore data volumes.
– Scans and deduplicates volume data automatically, resulting in fast, efficient space
savings with minimal effect on operations.
Data ONTAP
– Provides full-featured and multiprotocol data management for both block and file
serving environments through N series storage operating system.
– Simplifies data management through single architecture and user interface, and
reduces costs for SAN and NAS deployment.
Disk sanitization
– Obliterates data by overwriting disks with specified byte patterns or random data.
– Prevents recovery of current data by any known recovery methods.
