About Nexsan E18
The Nexsan E18™ is a block-level RAID storage system, representing a quantum leap in storage performance, density and efficiency with 18 SAS, SATA, or SSD disks in only 2U of rack space. The new Nexsan E-Series™ RAID controller delivers blazing performance and enterprise-class reliability, making the E18 the perfect storage solution for virtualized environments, databases, backup to disk, or general applications demanding high performance and top-tier reliability.
With never-before-seen efficiencies, the E18 allows organizations to add more capacity while lowering overall power, space and cost requirements. Relative to comparable storage systems, the E18 requires only 1/2 of the rack space. Active Drawer Technology™ makes servicing the drives a breeze, and keeps them online when the drawer is open, eliminating the need to power down for maintenance. AutoMAID® level 4 power savings technology places drives into low power states when they are not being accessed, saving up to 85% on power and cooling expenses.
High Performance
Available in single or dual controller configurations, the powerful E-Series controller contains 2GB of battery-backed cache with dual RAID engines to deliver blazing performance. Two 8Gbit FC ports and two 1Gbit iSCSI ports can
Enterprise-Class Reliability
The E18 meets the strictest business continuity demands with high availability features like full redundancy across all active components, including power supplies, ports, controllers, fans and disks. RAID sets can be automatically rebuilt with hot spares. Multi-path architecture ensures no single point of failure. State-of-the-art vibration dampening and air cooling channels ensure leading reliability.
Extreme Density
The E18's unique Active Drawer Technology™ represents the most innovative approach to high density management with two self-contained disk drawers. Each active drawer contains 9 disks and tachometer controlled push and pull fan modules. Specially designed cables enable continuous operation even when a drawer is momentarily pulled out to perform easy disk or fan service.
Unprecedented Energy Saving
Nexsan's exclusive AutoMAID® level 4 technology delivers up to 85% energy savings. Each disk group can easily be assigned a power savings policy with the Web-based management interface. When a disk group is not accessed for a specified time period, it can be put into a lower power-consuming state, saving up to 85% on power and cooling bills. For instance, in scientific computing applications, when workers go home, disks can be powered down. On first access, they are spun up and stay spinning. In backup to disk applications, drives can be powered down when backups are not being performed. No changes to applications or manual intervention is required to get the benefits of AutoMAID level 4.
High Performance Across Both Fibre Channel and ISCSI
E18 gives users the flexibility to utilize Fibre Channel or iSCSI connectivity or both simultaneously. Flexible, scalable and completely OS independent, E18 offers dual function FC and iSCSI connectivity with wire-speed throughput performance.

AutoMAID™ Energy Saving Technology:
Nexsan offers the first and only high performance, high capacity RAID storage systems to provide the energy saving benefits of MAID (Massive Array of Idle Disks). SATABeast employs Nexsan's revolutionary AutoMAID™ energy saving technology transparently place SATABeast disk drives into an idle state vastly reducing power consumption and operational costs. AutoMAID delivers the cost-saving benefits of MAID (Massive Array of Idle Disks) but without the limitations of slow access times and special host software. Nexsan's AutoMAID is granular to an individual drive or RAID set and offers multiple levels of energy savings enabling users to determine the right level of access speed and energy savings for their environment. AutoMAID is the first MAID architecture that supports VTL (Virtual Tape Libraries), full file format D2D and standard high performance RAID implementations.
By integrating Nexsan's AutoMAID™ technology into our high performance, multipurpose SATA storage arrays, users now have the flexibility to support multiple applications within the same storage subsystem. AutoMAID is user-selectable allowing this feature to be implemented as desired. AutoMAID can be applied selectively by drive units and can be disabled for volumes requiring the very best response time.
Key Points
- E18 with AutoMAID can cool all drives at 100% activity (even with one or two fans failed, even in a hot room)
- MAID reduces operational costs
- Nexsan’s AutoMAID gains the benefits of MAID without the limitations
AutoMAID Defined
- AutoMAID automatically reduces power consumption and heat generation on idle drives
- Trade-off between response times and power savings are user configurable
- AutoMAID behavior happens automatically and transparently to host – no software changesrequired
- AutoMAID is analogous to power saving modes on laptops
- Typical configuration settings:
- 30% savings – after 5 minutes of idle time, drives are programmed to unload heads and slow down to 4000 RPM. Very fast recovery time.
- 52% savings – after 5 minutes of idle time, drives are programmed to spin down. Recovery time on the order of 30 seconds.
AutoMAID Safety Features
- In maximum power saving mode, drive spin up is sequenced to reduce power surges
- Drives automatically wake up for periodic surface scan to ensure data integrity (typically, once a week for a few hours – user configurable)
- AutoMAID feature has no impact on performance if left on in data-intensive server applications – busy systems will never invoke the AutoMAID behavior
- Only two simple configuration settings – "timeout" and "power savings desired"
