4U , rack-mountable RAID storage systems which can hold up to 48 or 60 SATA, SAS, or SSD data disks.
The base models of the Nexsan E60™ and Nexsan E48™ use:
3Gb/s SAS for internal communication between the RAID Controllers and hard disks.
The V and VT variants use 6Gb/s SAS for internal communication.
The VT variants also have a turbo card installed in each RAID Controller which optimizes sequential writes in parity-based RAIDs.
There is no upgrade path between the base models and either the V or VT variants.
Aside from the difference in internal communication speed and the presence of the turbo card in the VT units,
there is no operational difference between the base models and either the V or VT variants.
Nexsan E48VT and Nexsan E60VT are available for purchase from Sunstar Company.

A Storage area network, or SAN, is a high-speed network of storage devices that also connects those storage devices with servers. It provides block-level storage that can be accessed by the applications running on any networked servers. SAN storage devices can include tape libraries, and, more commonly, disk-based devices, like RAID hardware.
A SAN must be highly available. A good SAN implementation will have built-in protection against just about any kind of failure imaginable. This means that not only must the links and switches composing the SAN infrastructure be able to survive component failures, but the storage devices, their interfaces to the SAN, and the computers themselves must all have built-in strategies for surviving and recovering from failures as well.
A good SAN delivers both high data transfer rates and low I/O request latency. Ideally, the SAN’s performance must be able to grow as the organization’s information storage and processing needs grow
A SAN that scales can provide a boost in performance with extra applications by separating high-volume I/O traffic from client/server message traffic.
Any well-managed enterprise will do a cost-benefit analysis before deciding to implement storage networking. The results of such an analysis will almost certainly indicate that the biggest payback comes from using a SAN to connect the enterprise’s most important data to the computers that run its most critical applications.
Imation’s Nexsan Assureon archive system, available from Sunstar Company, Inc. is a complete, turn-key archiving solution for fixed content data like document archiving, email archiving, medical/PACS archiving and the general archiving of all unstructured data.
All local and remote Assureon online archive systems can be managed from a web browser within a single-pane-of-glass. The web-based GUI makes it easy to create retention rules and associate them with files and folders. Once installed onto the Windows Servers and configured, the Assureon Windows Client copies or moves files onto Assureon leaving a small shortcut file behind, so user access to the file remains the same. Hyper-speed restores are available by using the shortcuts for immediate access as files are restored in the background.
Users are authenticated with Active Directory or with digital certificates to ensure they can only get to files for which they are authorized. Audit trails report on user’s activities such as file accesses and denials. Legal holds can be easily placed on any set of files, overriding their original retention periods.
Individual users do not change how they work as the archiving is transparent to them. Files and folders, though offloaded, appear to be in the same familiar locations thanks to the shortcut files that are left behind. Once archived, prior versions of files are available with the right click of the user’s mouse in Windows Explorer. A web-based GUI makes it easy to search the entire archive with role-based restrictions. All existing applications work unaltered with Assureon because there are no special APIs required.
Each time a file is saved, it is fingerprinted so its history and contents cannot be altered after the fact. This write-once, read many time (WORM) storage architecture is part of how Assureon meets even the strictest regulatory requirements such as HIPAA, SOX and SEC17.
Two copies of all files, along with their fingerprints, are stored on separate RAID disk sets. Two Assureon systems can be replicated to each other to protect against a site failure. Files are continually verified against their fingerprint, automatically repaired by their copies, and safeguarded by RAID disk arrays to ensure the utmost file protection and integrity. Native active/active replication protects against site disasters with automatic failover, while delivering increased performance over active/passive systems.
The Assureon data archive system supports both compliant and non-compliant policies simultaneously while competitors require two systems to be purchased in order to provide both. All files can optionally be encrypted with AES-256. The built-in key manager ensures that all keys are safely stored in 3 locations worldwide. Industry-leading single point deletion technology permits Assureon to effectively delete all copies of a file worldwide by destroying the file’s encryption key.
Multi-tenancy features enable service providers to offer archive-as-a-service. This also allows large organizations to achieve strict separation of departments or projects. An on-premise Assureon disk archive can replicate to a cloud-based archive service, which is powered by Assureon.
