Key StorageX Features

  • Phased migration: using GUI interface it was easy to configure migration policies (baseline, incremental and final copy). Reduced downtime window required to migrate the NAS data.
  • Security permissions and file attributes: StorageX copied security permissions (in Windows) and mode bits and file attributes (in Unix). No manual intervention or correction was needed.
  • Migration summary: detailed summary report of the migration with migration start, end time stamps, bytes copied, number files and folders copied, skipped or deleted files and error logs.

Customer Story

With data growth, equipment end-of-life (EOL), and increasing support costs it is very crucial for organizations to consolidate and eliminate older and more expensive storage systems. The cost of such data migration is significant and migration can present substantial business and technical challenges.

A variety of tools are required to move data between arrays from different vendors or to newer equipment. Traditional migration solutions do little to address these challenges. Host-based tools can reduce the performance of other business applications by consuming CPU cycles and I/O bandwidth. Array-based solutions either do not support heterogeneous storage environments, or offer a one-way transfer that locks customers into a single-vendor solution. Appliance-based solutions require a service technician to enter the data center, install the appliance in the data path between the host and the storage device, and then remove the appliance after performing the migration. The result is an expensive, intrusive approach that is not readily scalable and requires downtime before and after the migration. To efficiently meet ongoing migration needs, storage administrators need a simpler, less disruptive, and more cost- effective way to migrate data between heterogeneous storage arrays.

StorageX File Management

One such solution for file based data management and migration is Data Dynamics StorageX. StorageX is a software based solution which facilitates file based storage management and migration.  StorageX distinguishes itself by being a very simple, yet powerful GUI based tool which simplifies the migration, consolidation, and archiving of file data in large, complex, heterogeneous file storage environments. StorageX is fully automated and has a policy driven approach to data migration and management.

StorageX supports various NAS devices (EMC VNX/VNX OE for File and Isilon/OneFS, NetApp/Data ONTAP 7-Mode and Cluster Mode, Windows, and Linux) as both sources and destinations, as well as stand-alone CIFS and NFS file storage resources. StorageX software can be installed on virtual or physical servers. Installation is a simple and straightforward process. We migrated more than 3,000 NAS between variety of source and destinations storage systems/servers. Some of the major benefits of StorageX are explained below.

Benefits of StorageX:

  1. GUI interface:
    The graphical user interface makes it very easy to handle bulk NAS migrations. With the GUI, we can add storage resources (source and destination) and create data movement policies for NFS/CIFS share by specifying the replication and migration options.
  2. Migration Policies:
    Migration policies define the data movement between source and destinations. For CIFS shared folders and NFS exports, there are several configuration options available. Carefully input the data in the migration template as it is the base for deciding the migration options. Options are available to copy directories only, delete orphaned file/folder on destination, copy security settings, choose file attributes, filter files by age, exclude files/folders, etc.  After the initial baseline data copy phase, continuous incremental copies ensure replication of new, locked, or recently modified files on the source to the destination.In the final cut-over phase, StorageX options allow you to remove user access to the source, perform a short, final sync to copy any new files recently added or updated, and then share the new destination with users.This phased migration (baseline, incremental and final copy) approach reduces the overall downtime window required to migrate the NAS data.
  3. Migration Schedule:
    Once the baseline copy is completed, subsequent incremental copies can be automated through migration schedules. Migrations can be scheduled every minute, hourly, daily, weekly, etc.
  4. Automated Emails:
    Email notifications can be configured for effective monitoring. We did not need to login to the tool to check the migration status, emails alerted us under different conditions (completed successfully, completed with errors/warnings or cancelled).
  5. Migration Summary Report:
    Summary reports give a detailed status of the migration with migration start, end time stamps, bytes copied, number files and folder copied. If the migration is cancelled with error or if it is unsuccessful, the error logs clearly indicate the cause so we can troubleshoot to fix the issue and retry the data copy. If certain files are skipped or deleted, that is also indicated in the summary.
  6. Security Permissions and File Attributes:
    A major challenge in NAS data migration is copying the security permission (in Windows) and mode bits and file attributes (in Unix). StorageX is able to copy security permissions and file attributes over smoothly from source to destination based on the options specified in the migration template.  No manual intervention or correction is needed after the final data copy.

Have you been putting off the need to update or replace thousands of aging NAS volumes containing millions of old files?

If so, you need StorageX.

StorageX is the ONLY file management solution proven capable of managing massive petabyte migrations.  It is not wonder that six of twelve world’s largest banks rely on StorageX.
