Attach Expansion Unit to Main Storage Unit
The Nexsan E48VT/E48XV requires another Nexsan unit to provide RAID functionality and host/network connectivity. Up to two expansion units can be connected to a single Nexsan RAID storage unit by “daisychaining” the two expansion units together. Expansion units should be mounted in the same rack as the unit to which they are to be connected or in an immediately adjacent rack.
E-Series V features an advanced active/active controller design, including use of a dedicated hardware engine, or “turbocharger”, which accelerates RAID parity generation and doubles the sequential write performance over the prior version of E-Series. The turbocharged E-Series V is ideal for back-up/recovery applications and continuous data streaming bulk storage applications.
High-Density, Power Efficient
Organizations deploying E-Series V systems are able to mix and match capacityoptimized HDDs, performance-optimized HDDs and SSDs to accommodate applications based on performance or capacity needs. E-Series V systems consume less than one-third of the power in one-third of the rack space of typical arrays, with up to 480 terabytes of capacity in just one 4U, and up to a total of 1.44 PB in a fully-scaled, 12U configuration. Users of E-Series V systems can engage Nexsan AutoMAID disk management capabilities to reduce power consumption by up to 87 percent, reducing operating expenses and extending the overall life of the system.
E-Series V systems exceed the most stringent reliability demands, leveraging an innovative mechanical design including Cool Drive Technology™ and antivibration design that significantly reduce heat and vibration in the unit while improving system reliability and performance. The reliability of E-Series V is qualified through extensive stress testing before shipment. Array-based snaps and asynchronous replication extend E-Series V data protection capabilities.
Encryption at Rest
E-Series encryption is configured to automatically encrypt data by using selfencryption drives (SED) with AES-256 encryption, so you know that data at rest is fully protected. The E-Series management interface allows the encryption/ decryption process to be transparent and does not compromise performance. To prevent unauthorized access to the data, the storage system must authenticate itself with the drive using an authentication key that is established upon the first time use of the drive. The encryption key is managed by the controller, so no key management is required by the user. With optional FIPS 140-2 level 2 certified self-encrypting drives, the E-Series FIPS 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. Re-purpose or retire your storage without compromising data by allowing E-series to cryptographically erase all encrypted data.
Highly Resilient, Continuously Available
The E-Series system features high-availability architecture, with multipathing support and dual redundant, hot-swappable active components. SNMP alerts or email notifications are sent to the administrator in the event of a component failure and upon a drive failure a spare drive is automatically rebuilt into the RAID set. With up to 16GB of battery-backed and flash-protected cache per controller, the E-Series solution mirrors cache between controllers in a dual controller configuration. Active Drawer Technology overcomes the challenges of competitive arrays by allowing a single drawer of drives to be pulled out and serviced easily while keeping your data available.

With ever-increasing volumes of data, IT departments are looking for storage systems that minimize both the rack space required and power and cooling expenses. Buildings with infrastructures designed 10 years ago are now reaching their limits on what they can support with power and cooling ranking among the top concerns of new datacenters.
Nexsan is the industry leader in both of these areas. AutoMAID power management technology, built in to the E-Series disk arrays, can save up to 87% on power and cooling bills, as explained in this paper.
Best Usage Scenarios
AutoMAID allows the administrator to define policies that place drives into progressively lower power states based on disk activity. In a typical disk array, there may be several RAID disk sets. The AutoMAID power management policy is per RAID set, not necessarily across all of the drives in the storage system. AutoMAID policies are based on the time of day, day of the week, and amount of time elapsed since the last access to the disk set. A true “set and forget” setting, AutoMAID allows the administrator to define the policies that will allow for the least disruption to productivity by users. If a Nexsan storage system is not idle, AutoMAID does not kick in; only when RAID sets hit policy limits on inactivity does AutoMAID begin to progressively transition to lower power usage.
One common use for AutoMAID is for backup to disk. At 10PM the backups start, and all drives are running at full speed to complete the nightly backup as quickly as possible. But at 7AM the backups are done, and that RAID disk set will not be accessed for another 15 hours. So a policy is set that says if none of the disks are accessed for 30 minutes, go into a power savings state. Then at 10PM the first write takes about 30 seconds longer than usual, then the entire disk set runs at full speed while backups are being performed.
Another common use is when large scientific projects are being stored. Perhaps the scientists are working on the Mars data, and the Moon data is sitting idle. This is the ideal time for AutoMAID to spin down the RAID disk set housing the Moon data until the Moon data is accessed again. The nice thing about AutoMAID is that the policies are easy to set up and change. Users and applications are unaware of the power efficiencies that are occurring. If a set of disks is being actively accessed, they will stay running at full speed for all users. It couldn’t be simpler or more effective.
Ideal for Backup-to-Disk and Bulk Storage Applications
Lastly in video surveillance, the storage system can be configured with 7 RAID disk sets, one for each day of the week. In this configuration only one RAID disk set needs to be powered up at any given time to accept that day’s data, resulting in startling power savings. Of course all drives are accessible as needed, should someone wish to view or process the video captured on prior days.
There are 5 levels of power savings that AutoMAID supports in the E-Series:
Sub-second recovery time
About 15% to 20% savings
Heads unloaded (slows to 4000 RPM)
15 second recovery time
About 35% to 45% savings
Stops spinning (sleep mode; powered on)
30 to 45 second recovery time
About 60% to 65% savings
Stops drive electronics
30 to 45 second recovery time
About 70% savings
Turn off E60X expansion enclosure
30 to 46 second recovery time
About 87% savings with SATA
About 92% savings with 15K SAS
