Hammerspace announces version 4.4.0

Hammerspace announces a new software release, version 4.4


Hammerspace is thrilled to announce the general availability of version 4.4 which adds an expanded portfolio of services and features to help businesses with their SDS and hybrid multi-cloud needs.


With this release, Hammerspace adds a number of Enterprise features including support for larger number of shares, migrating data directly between different cloud tiers and WORM. In addition to that, a number of Usability enhancements for UI and data assimilation are included in this release as well. Furthermore, Hammerspace now supports Enterprise RedHat Linux 7.8 NFS v4.2 clients with version 4.4.


Last-but-not-least, Hammerspace version 4.4 also offers tech preview of the Universal Global Namespace, Synchronous Data Mirroring and a Capacity Planning tool that helps customers better plan their capacity needs over time.


With these new capabilities, Hammerspace customers can easily consume data across hybrid and multi-cloud environments without compromising on security, performance, availability, or ease of use.


New Features in version 4.4


Support for large number of Shares

With version 4.4, Hammerspace can now scale up to hundreds of shares in a cluster.

Cloud to Cloud Mobility

When moving files between cloud tiers, data had to be rehydrated to NAS before getting uploaded to the destination cloud bucket. In Hammerspace version 4.4, this extra hop has been removed, so data can now be migrated directly from one cloud bucket to another.

Capacity reporting when adding new volumes

Hammerspace version 4.4 has the ability to detect and report used volume capacity when adding a new volume to the cluster. In addition to that, auto detection is built in to avoid data movement in order to balance capacity unless initiated by the user. This helps reduce any unexpected data movement when new storage volumes are added.

WORM support

Hammerspace now allows setting WORM specific attributes for WORM_EXPIRY and LEGAL_HOLD_EXPIRY dates. Once they are set, they cannot be deleted, they can only be changed to be effective at a later date for the data in the share. WORM support can be enabled using objectives across files, directories and shares, giving customers finer grained control over different types of files.


Functional Enhancements in version 4.4

GUI Scalability improvements

Along with the added support for more shares, a number of enhancements have also gone into Hammerspace version 4.4 for improving GUI responsiveness when handling large number of shares, volumes and storage nodes.

Assimilation enhancements and Performance improvements

Hammerspace supports assimilating third party NFS and SMB data, non-disruptively into its active namespace without making any changes to the original data. With this latest release, Hammerspace has added a number of usability enhancements focused on additional logging, non-disruptive error handling, ability to cancel assimilations and a better UI experience. In addition to that, this release also contains substantial performance improvements when assimilating NFS and SMB data.


Technology Preview Features

A technology preview feature is functionality exposed in the product for customers to test. The feature is not supported for Production usage however it is generally made available with full product support in the sub-sequent release.

Capacity planning analysis

HS provides customers with tools that help them plan their storage needs by allowing them to simulate data uploads to cloud without actually moving any data, while taking into account storage efficiency features like data compression and dedupe.

Synchronous Data Mirroring

As a tech preview feature, Hammerspace can now synchronously mirror data to different volumes for increased resiliency.

Global File System

Customers can now deploy a single namespace across different geographical sites and replicate data and metadata across these sites. The data in global shares are available Read-Write on multiple sites at the same time. Initial support goes up to 16 sites concurrently active on the same share.


NFS Client Support

Additional NFSv4.2 Client Support

Hammerspace has added support for Red Hat Enterprise Linux 7.8 clients for NFS 4.2 access in version 4.4. Red Hat Enterprise Linux 7.7 clients are already supported for NFSv4.2 access.
