About Veritas Access

Veritas Access Administrator's Guide

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 or private cloud based on policies.

You can use Veritas Access in any of the following ways.

Table: Interfaces for using Veritas Access

Interface

Description

GUI

Centralized dashboard with operations for managing your storage.

See the GUI and the Online Help for more information.

RESTful APIs

Enables automation using scripts, which run storage administration commands against the Veritas Access cluster.

See the Veritas Access RESTful API Guide for more information.

Command-line interface (CLI or CLISH)

Single point of administration for the entire cluster.

See the manual pages for more information.

Table: Veritas Access key features describes the features of Veritas Access.

Table: Veritas Access key features

Feature

Description

Multi-protocol access

Veritas Access includes support for the following protocols:

WORM storage for Enterprise Vault Archiving

Veritas Access can be configured as WORM primary storage for archival by Enterprise Vault.

Veritas Access is certified as a CIFS primary WORM storage for Enterprise Vault 12.1.

For more information, see the Veritas Access Enterprise Vault Solutions Guide.

WORM support over NFS

Veritas Access supports WORM over NFS.

See Setting WORM over NFS

Creation of Partition Secure Notification (PSN) file for Enterprise Vault Archiving

A Partition Secure Notification (PSN) file is created at a source partition after the successful backup of the partition at the remote site.

For more information, see the Veritas Access Enterprise Vault Solutions Guide.

Managing application I/O workloads using maximum IOPS settings

The MAXIOPS limit determines the maximum number of I/Os processed per second collectively by the storage underlying the file system.

See About managing application I/O workloads using maximum IOPS settings

Flexible Storage Sharing (FSS)

Enables cluster-wide network sharing of local storage.

See About Flexible Storage Sharing

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.

Veritas Access moves the data from the on-premises tier to Amazon S3, Amazon Glacier, Amazon Web Services (AWS), GovCloud (US), Azure, Google cloud, Alibaba, Veritas Access S3, IBM Cloud Object Storage, and any S3-compatible storage provider based on automated policies. You can also retrieve data archived in Amazon Glacier.

See Adding a cloud tier for a scale-out file system

See Configuring the cloud as a tier for scale-out file systems

SmartIO

Veritas Access supports both read and writeback caching on solid state drives (SSDs) for applications running on Veritas Access file systems.

See About SmartIO for solid-state drives

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 and on-premises.

See About Veritas Access SmartTier

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.

See About snapshots

Deduplication

You can run post-process periodic deduplication in a file system, which eliminates duplicate data without any continuous cost.

See About data deduplication

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.

See About compressing files

Erasure-coding

Erasure-coding is configured with the EC log option for NFS use case.

See Support for erasure-coding in a cluster file system (CFS) for NFS use case

IP load balancing

With IP load balancing, a single virtual IP is used to act as a load balancer IP which distributes the incoming requests to the different nodes in the Veritas Access cluster for the services that are run on an active-active cluster.

See IP load balancing

iSCSI target

Veritas Access as an iSCSI target can be configured to serve block storage. iSCSI target as service is hosted in an active-active mode in the Veritas Access cluster.

See About Veritas Access as an iSCSI target

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.

See About Veritas Access as a NetBackup client

OpenDedup integration

Integration with OpenDedup for deduplicating your data to on-premises or cloud storage for long-term data retention.

See the Veritas Access NetBackup Solutions Guide for more information.

OpenStack plug-in

Integration with OpenStack:

Quotas

Support for setting file system quotas, user quotas, and hard quotas.

See About quotas for usage

Replication

Periodic replication of data over IP networks.

See About Veritas Access episodic replication

See the episodic(1) man page for more information.

Synchronous replication of data over IP networks

See About Veritas Access continuous replication

See the continuous(1) man page for more information.

Support for LDAP, NIS, and AD

Veritas Access uses the Lightweight Directory Access Protocol (LDAP) for user authentication.

See About configuring LDAP settings

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 with a self-contained configuration. An isolated storage pool protects the pool from losing the associated metadata even if all the configuration disks in the main storage pool fail.

See About configuring storage pools

Performance and tuning

Workload-based tuning for the following workloads:

  • Media server - Streaming media represents a new wave of rich Internet content. Recent advancements in video creation, compression, caching, streaming, and other content delivery technology have brought audio and video together to the Internet as rich media. You can use Veritas Access to store your rich media, videos, movies, audio, music, and photos.

  • Virtual machine support
