Overview

ArcaPix Ngenea HSM is an extremely fast, highly scalable, data management layer unifying PixStor, cloud and third-party storage into a single PixStor global namespace. ArcaPix Ngenea HSM transparently tiers files to external storage freeing local storage space. Applications and users see an extremely cost-effective standard POSIX file system (PixStor, NFS, or SMB) within their existing namespace no matter where the data is stored, with no change to user or program access. Files are accessed directly from high-speed IBM Spectrum Scale storage as needed.

Migration

ArcaPix Ngenea HSM performs both automated or manual migration of files to storage endpoints. Migrations can trigger when storage capacity crosses a defined threshold or on a scheduled basis. Command line utilities provide the ability to manually manage datasets as required.

Transparent Recall

Files are recalled when accessed by applications. ArcaPix Ngenea HSM transparently intercepts the generated file open request and performs the task of retrieving the object from its associated storage endpoint.

Targeted Recall

ArcaPix Ngenea HSM can perform targeted singular or multiple file retrieval from a storage endpoint. File recall can be driven via the PixStor Policy Engine or via command line utilities.

Certified for Spectra Logic BlackPearl Spectra S3

ArcaPix Ngenea HSM supports Spectra S3 Bulk GET and Spectra S3 Bulk PUT, ensuring the fastest operation with Spectra Logic BlackPearl systems. ArcaPix Ngenea HSM is a fully certified Spectra S3 client.

Full Path Retention

Upon migration to a target, ArcaPix Ngenea HSM retains the full file path and filename. This capability provides the ability to read data from the storage endpoint at other locations, providing a seamless file delivery workflow.

ACL Support

ArcaPix Ngenea HSM captures the source filesystem permissions of the file and/or directory and stores the permissions in the target upon migration. Files and directories can be restored with their originating ACLs to alternate compatible filesystem destinations.

Multiple Storage Targets

ArcaPix Ngenea HSM can store files in (and recall from) different storage targets, based on a data management policy or simply selecting by file path or file name.
