SafeGuard™ Protection
SafeGuard Overview
Protect your data from all angles with SafeGuard. DNF products offer many level of protection for your data, ranging from hardware redundancy, RAID protection, management protection, site protection, RAID Certification, and more. With SafeGuard in place IT organizations can ensure their storage meets the availability, redundancy and protection your organization requires. Here are the key elements of SafeGuard below:
Location Based Safeguards and Data Protection
What happens during a site failure?
In the event of a power outage, site failure or other emergency situation, ensure your data is available at an alternate location. Types of location based protection can include Replication, Mirroring or Continuous Data Protection.
Isolated System Management Data
Where is the Software Management stored?
With isolated system management, you can ensure your system management controls or operating system is from the main array, ensuring your control panel will be available in the event of a drive failure or virus attack in your data. With separate partitions or separate physical disks for system management, you will add an extra layer of security to your storage infrastructure.
System Management Integrity
What happens if a virus or worm infiltrates my system management data?
With System Management Integrity, your management data is insulated from malicious worms, hackers or attacks, allowing you to manage and control system changes, track system configurations and manage installed software. This can prevent the execution of unauthorized programs and unauthorized attempts to modify approved applications.
Multiple Connections
How is my storage system connected?
Configurations might offer two physical connections to networks or servers, giving you the option of creating two or more independent paths to your data.
Connection Multi-Pathing, Load Balancing ad Failover
What happens if one of my connections fails?
With Multipathing and failover, your system will automatically detect the failure of your pathway, and allow the alternate connection to maintain communications with the system to ensure your data is still accessible or transferred in the event of a cable failure. This con happen on the storage system or host system depending on the configuration.
Redundant Controller Modules
What happens if my controller fails?
Redundant controller modules can be configured in an Active-Active or Active-Passive configuration. With either configurations, one controller module can fail, and the system will recognize the failure and route all requests through the available controller module, offering continuous system availability.
Hot-Swappable Disk Drives
Can I replace troubled disks on the fly?
With hot-swappable disk drives, you can replace your failed disk without shutting down the system, saving you from costly downtime.
RAID Protection
Are my disks redundant?
RAID Protection creates a Redundant Array of Disks. Each official RAID level offers varying degrees of redundancy and options for parity and data protection.
RAID Certification
Are my disks certified to be used in RAID configurations?
DNF has developed an extensive RAID Certification testing procedure. Each drive used by DNF goes through a sophisticated and grueling 120 hour testing process, weeding out units that exhibiting signal quality problems, data mismatch errors, temperature and power regulation issues, or other conditions that escaped the manufacturer's testing process. At the end of the process, you can ensure these disks will perform consistently in any RAID configuration.
Hot-Swappable System Components
Can I replace major System Components without taking the system offline?
With hot-swappable power supplies, fans and cooling modules, you can stay online and replace these standard modules. Hot-Swappable components also offer redundancy allowing you to maintain operation even when one module fails.
