Nexsan E-Series High Density Storage

Encryption

E-Series encryption is configured to automatically encrypt data by using self encryption drives (SED) with AES-256 encryption, so you know that data at rest is fully protected. With optional FIPS 140-2 level 2 certified self-encrypting drives, the E-Series SED allows you to meet regulatory and compliance needs for securing data at rest. E-Series SED provides the security you need without forgoing performance or usability.

Anti-Vibration Design

State-of-the-art vibration dampening improves system performance and reliability.  Hard drives are arranged in couplets and counter-rotated creating a mechanical design that eliminates vibrations between drives and naturally provides a cooling channel to the hottest part of the drives, both of which maximize drive lifetime.

Volume Migration

Allows volumes to be moved seamlessly from one storage array to another without interruption to host access. Use case examples: migrate a full volume to a new larger volume, performance requirements change, change the RAID level of a volume.

Cool Drive Technology

Uses both push and pull fans to ensure there is always air flowing front to back over the drives, even if a fan should fail. A designed air channel combined with the counter rotating of the hard drives maximizes airflow leading to improved reliability and performance.

Active Drawer Technology

Innovative ease-of-use functionality makes deploying and managing dense storage a simple task for the resource constrained IT administrator.  Simply pull out a drawer to service drives or fans while the system is being actively used – all with no application downtime.

SSD Health Monitoring

Just because SSDs don’t have moving parts, doesn’t mean they don’t wear out. SSD Health monitoring shows the amount of writes remaining on SSDs, providing the ability to proactively replace SSDs before they fail due to over-usage. The E-Series array will give you different levels of alerts depending on the amount of life left on your SSD.

Snapshots

Ideally used as part of a backup plan, for restoring to a known good configuration, and for testing new software/configurations without affecting the original data.  An E-Series snapshot also includes the option to do snapshot cloning.  This allows for internal volume migration or the ability to create a new volume from a snapshot. 

Replication

Provides a means of backing up volume data on another E-Series storage unit, either locally or at another geographically dispersed site. If a source volume fails, the replica of that source can be “promoted” to full volume status, allowing the data to be accessed. Although the replica always reflects the state of the volume at the last replication, a snapshot taken prior to the last replication can be mounted to view previous states. Replication can be used as part of an overall backup or disaster recovery solution.
