The Nexsan E18™, a member of the Flexible Storage Platform™, is Nexsan's next generation of high performance, high density and energy-efficient storage solution. Upping the ante over Nexsan's SATA/SASBoy® 14-drive 3U storage system, the E18 is a next-generation, high performance, 18-drive 2U storage system. The E18 supports SATA, SAS and SSD drives to flexibly meet varying storage needs for high performance, high capacity or both. The E18 is designed for applications that require enterprise-class performance at a mid-market price.
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.
he 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.

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.
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 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.
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.
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.
All Nexsan disk arrays come standard with a software suite that provides comprehensive storage management. Nexsan Storage Manager makes management easy with a single, intuitive browser-based interface. All local and remote Nexsan storage products can be easily and securely managed and monitored. Windows users can utilize Microsoft’s storage management tools to perform common administrative tasks, thanks to VDS-compliance. Integration with Microsoft Multi-path I/O (MPIO), as well as multi-path for Linux, OS X, the E18 delivers higher performance and fault tolerance. With the Nexsan QuickStart configuration wizard, the disk array can be up and running in under 10 minutes. Customizations are a breeze with the Nexsan Storage Manager GUI.
