Nexsan E60X RAID Array

60 disk expansion chassis

The Nexsan E60X is an expansion chassis that can increase the capacity of the Nexsan SASBeast or the SATABeast by up to 180TB with SATA drives in a 4U form factor. Compatible with SAS and SSDs drives as well, the E60X features three 20 disk drawers featuring patented Active Drawer Technology, enabling IT departments that need to expand the capacity of their existing Nexsan RAID arrays without a maximum level of flexibility.

Featuring up to two dual-redundant x 12Gbps SAS high speed connections, the Nexsan E60X expansion chassis is designed to be seamlessly managed via the SATABeast and SASBeast units that have the expansion interface with the 8Gbps FC beast controllers.

Active Capacity Disk Drawers

To maximize the reliability and ease-of-use of this disk expansion unit, the Nexsan E60 features a design layout of the disk drives being located in 3 self-contained disk drawers. Each drawer contains 20 disk bays, and tachometer -controlled push and pull fan modules. Other features of this unique design include:

• Each drawer can have a different drive type of SAS, SATA, SAT+SAS or SSD
• Use any Nexsan certified and shipping drive (SAS, SATA & SSD)
• Create multiple RAID sets within a single drawer
• Create a RAID set across two or three drawers
• Phone-home feature that notifies of system status

Nexsan’s specially-designed cables for this disk expansion unit enables drawers to be pulled out so service can be performed to disks and fan within the unit without affecting operation or availability.

Reliability, Availability, Serviceability

The design of the Nexsan E60X expansion unit includes many of the reliability features included with their other disk arrays. Features include:

• Dual redundant load sharing 1600W 200-260V power suppliesss
• Redundant, individually hot-swappable disks, expansion interface modules, and fans
• Anti-Accumulative Rotational vibration design maximizes disk reliability
• Horizontal mid-plane maximizes cooling for optimal operating conditions
• Multi-path architecture to eliminate single points-of-failure

AutoMAID™ Green Storage Technology

Nexsan’s patented MAID (Massive Array of Idle Disks) technology, AutoMAID, is designed to provide real cost savings by reducing the energy requirements & thermal output of unused drives. This feature comes standard on all of Nexsan’s E60X disk arrays, and provides transparent cost savings without requiring any software changes. AutoMAID allows IT to choose what combination of cost savings and performance requirements fits their business needs, with four levels of “idleness”:

Level 1: at this level, disks can achieve 15% - 20% savings by unloading the head. The disks keep spinning though, providing sub-second recovery times

Level 2: achieve 35% - 45% savings by unloading the heads and slowing the disk down to 4000 RPM. At this level, recovery times average 15 seconds.

Level 3: further increase powersavings by stopping the disk spin and putting it into sleep mode, but powered on. This level provides 60% - 75% savings, and 30-45 second recovery times.

Level 4: maximize power savings by approximately 87% by powering the drive off, while still featuring 45-60 second recovery times to initial I/O requests

Data is continuously verified with Nexsan’s AutoMAID technology, which performs periodic surface scans to ensure data integrity.
