Online Capacity Expansion

The Online Capacity Expansion feature makes it easy to add capacity as needed without disrupting application availability. Drives and expansion units can be added online, RAID sets can be expanded without service interruption, and target volumes can be grown while maintaining access to data.

  • Add drives and expansion units with no downtime
  • Expand RAID sets online with no service interruption
  • Maximize application availability by growing target volumes online
Why You Need It...
  • With Online Capacity Expansion, you can grow your RAID sets and volumes without service interruption

Snapshots are a great way to accelerate backups, reduce the physical capacity consumed to protect data and increase backup efficiencies. More importantly, Snapshots provide the fastest and most granular way to recover data. By taking instant, disk-based point-in-time images of storage volumes located on any of your SnapSAN S1000s, you can roll back to the point in time before malware or virus intrusion. By integrating directly with Microsoft’s Volume Shadow Copy Service (VSS) feature you’ll be able to create complete, application consistent snapshots to fully protect all of your VSS-aware applications such as Microsoft Exchange and SQL.

Writable snapshot supports allows for a flexible test environment without putting your critical data at risk and without the need to do a complete volume copy of the data to test applications under development or for piloting purposes.

  • Reduce the time and space required for your backups
  • Maintain application consistency with Windows VSS integration
  • Writable snapshots for application test and development environments
Why You Need It...
  • Snapshots provide flexible, point-in-time backup and recovery for your storage volumes

The remote replication software enables administrators to replicate data over their LAN or WAN from S1000 to S1000. Data protection and backup solutions play an important role in todays storage architectures. Ideally suited for site-to-site data protection, the remote replication software helps protect from disasters and prevents data loss.

  • Asynchronous replication for logical volumes
  • Full replication and incremental replication support
  • One source target to multiple destination targets
  • Supports 1GbE and 10GbE iSCSI solutions
Why You Need It...
  • Replicate data across multiple business locations for maximum data protection

Drive Spin-Down

All S1000 systems are equipped with a variety of “Green” features and advanced cooling mechanisms which maximize energy efficiency and power savings. The auto disk spin-down feature ensures that the system is consuming only the amount of power required to serve data.

Environmental temperatures are monitored and fans are automatically adjusted as needed to keep the system cool and running optimally. In addition, the power supplies are optimized to further maximize power efficiencies.

  • Auto spin-down feature
  • Temperatures monitored and fan speed automatically adjusted
  • Power supplies optimized for energy efficiency
Why You Need It...
  • Drive spin-down reduces power consumption and extends drive life
