NexSAN E18 - 180 Drives - High performance, high density green storage in 2U

The Nexsan E18™ is the next generation of high performance, high density and energy-efficient storage for Nexsan products. The E18 delivers 18 drive bays in only 2U–nearly double the capacity per U compared to its predecessor, now 54TB with 3TB SATA drives or over 10TB of high-performance, redundant SAS. As such, the E18 is designed for applications that require enterprise-class performance at a mid-market price.

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.

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 be used simultaneously to support multiple workloads on a single, small array.

(4) 10GbE and (4) 1Gb iSCSI connections, Dual Controller, 18 Bay, 2U, 4GB Cache
(2) 1Gb iSCSI connections ONLY, Single Controller, 18 Bay, 2U, 2GB Cache

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.

The system employs the new Nexsan E-Series RAID controller–available in single or dual controller configurations–and contains up to four 8Gb Fibre Channel ports and up to four 1Gb iSCSI ports to deliver higher bandwidth and path resiliency. Nexsan's Active Drawer Technology™ enables two sliding, active drawers that hold nine drives in each, allowing them to be quickly and easily serviced by one person while remaining online. 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.

The E18 is ideal for transactional applications as well as storage for virtualized environments that utilize Windows, Linux, VMware, Xen or Hyper-V–which access storage randomly, require high performance and require no single-point-of-failure configurations. Request a Quote

Up to 18 Disks	Industry leading storage density and capacity in 2U.
SATA, SAS and SSD drives	High speed SAS and SSD drives can be mixed with SATA drives to deliver performance to transactional applications or virtual hosts.
Active Drawer Technology™	Allows one person to easily access hot-swappable disks and fans, in any of the two sliding drawers, which remain operational when opened.
High Availability	Can be configured so there is no single-point-of-failure between the servers and storage system, or within the storage system. All power, fans, disks and I/O ports are fully redundant.
Active / Active	Both controllers service storage requests, delivering twice the performance of the active/passive architecture offered by others.
Energy Savings	AutoMAID® is the storage industry's most sophisticated power management system. Infrequently accessed data allows drives to be powered down when not in use while offering near instantaneous access to data when needed. AutoMAID saves up to 87% on power and cooling costs.
Anti-Vibration Design™	Hard drives are mounted so that all disks are not spinning in the same direction. In addition, the anti-vibration design of the chassis provides unprecedented hard drive MTBFs.
Cool Drive Technology™	The high density chassis is specially designed for uniform airflow that ensures optimal thermal operation. The hot-swappable fans in the front and rear of the active drawers allow proper push/pull airflow.

Green Storage

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 modes, 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 – the timeout and the level of power savings desired
