Veritas Access is a software-defined scale-out network-attached storage (NAS) solution for unstructured data that works on commodity hardware. Veritas Access provides resiliency, multi-protocol access, and data movement to and from the public cloud based on policies.
Table: Veritas Access key features describes the features of Veritas Access.
Table: Veritas Access key features
|
Feature |
Description |
|
Simple administration through a CLI or a GUI interface |
CLI interface that provides a single point of administration for the entire cluster. GUI interface that provides a centralized dashboard with operations for creating file systems, shares, and storage pools. |
|
Multi-protocol access |
Veritas Access includes support for the following protocols:
|
|
Flexible Storage Sharing (FSS) |
Enables cluster-wide network sharing of local storage.
|
|
Scale-out file system |
The following functionality is provided for a scale-out file system:
|
|
Cloud as a tier for a scale-out file system |
Veritas Access supports adding a cloud service as a storage tier for a scale-out file system. You can move data between the tiers based on file name patterns and when the files were last accessed or modified. Use scheduled policies to move data between the tiers on a regular basis.
|
|
SmartIO |
Veritas Access supports read caching on solid state drives (SSDs) for applications running on Veritas Access file systems.
|
|
SmartTier |
Veritas Access's built-in SmartTier feature can reduce the cost of storage by moving data to lower-cost storage. Veritas Access storage tiering also facilitates the moving of data between different drive architectures.
|
|
Replication |
Periodic replication of data over IP networks.
|
|
Snapshot |
Veritas Access supports snapshots for recovering from data corruption. If files, or an entire file system, are deleted or become corrupted, you can replace them from the latest uncorrupted snapshot.
|
|
Deduplication |
You can run post-process periodic deduplication in a file system, which eliminates duplicate data without any continuous cost. This feature is available in the command line (CLI) only, not in the GUI. See the Veritas Access Command-Line Administrator's Guide.
|
|
Compression |
You can compress files to reduce the space used, while retaining the accessibility of the files and having the compression be transparent to applications. Compressed files look and behave almost exactly like uncompressed files: the compressed files have the same name, and can be read and written as with uncompressed files.
This feature is available in the command line (CLI) only, not in the Management Server console. See the Veritas Access Command-Line Administrator's Guide. |
|
NetBackup integration |
Built-in NetBackup client for backing up your file systems to a NetBackup master or media server. Once data is backed up, a storage administrator can delete unwanted data from Veritas Access to free up expensive primary storage for more data.
|
|
OpenStack plug-in |
Integration with OpenStack:
|
|
Quotas |
Support for setting file system quotas, user quotas, and hard quotas.
|
|
Support for LDAP, NIS, and AD |
Veritas Access uses the Lightweight Directory Access Protocol (LDAP) for user authentication.
|
|
Partition Directory |
With support for partitioned directories, directory entries are redistributed into various hash directories. These hash directories are not visible in the name-space view of the user or operating system. For every new create, delete, or lookup, this feature performs a lookup for the respective hashed directory and performs the operation in that directory. This leaves the parent directory inode and its other hash directories unobstructed for access, which vastly improves file system performance. By default this feature is not enabled. See the storage_fs(1) manual page to enable this feature. |
|
Isolated storage pools |
Enables you to create an isolated storage pool, which contains its own configuration files. An isolated storage pool protects the pool from losing the associated metadata if a disk in another storage pool fails.
|
|
Performance and tuning |
Workload-based tuning for the following workloads:
