Description
|
|
Multi-protocol access
|
Veritas Access supports 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.

|
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.
This feature is available in the command line (CLI) only, not in the GUI.
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
This feature is available in the command line (CLI) only, not in GUI.
|
|
Erasure coding
|
Erasure coding is configured with the EC log option for the 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
|
|
Veritas Access as an iSCSI target for RHEL 7.x
|
Veritas Access as an iSCSI target can be configured to serve block storage. iSCSI target as a service is hosted in the 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 namespace 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, 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.
