GreenRAID Energy-smart SMB and Entry-Level Class Storage

Promise redefines departmental/SMB class storage with the energy-smart VessRAID SAS series offering scalability, reliability and affordability. User-definable power-scheduling and the 80PLUS power supplies can reduce power consumption by up to 70%.  Available in 2U/12-bay and 3U/16-bay form factors, the solution scales up to 80 bays.

VessRAID features a single RAID controller with dual SAS host ports, offering users the bandwidth and expansion capabilities for business critical applications including backup, archiving and video surveillance. The advanced SAS backend accommodates both SAS and SATA drives, allowing users to precisely match drive technologies to their application profile for maximum price/performance. 

Reliable External RAID Storage
In todays fast-paced business environment, users generate large amounts of unstructured data creating a demand for more storage. Companies that are storing digital content such as video, music and images, and are constrained by industry regulations regarding document retention, are changing their storage requirements. The VessRAID line of storage systems provide a cost-effective way for businesses to easily meet storage needs, allowing users to keep data online longer while providing fast access and reliable data protection. VessRAID family of products offers users state-of-the-art storage technology with the proven reliability you expect from Promise Technology.

Capacity and Performance to Meet Multiple Storage Requirements

Cloud Computing

Matching IT resources to real-life business needs is an ongoing issue
for IT managers and having the ability to create inexpensive SAS, iSCSI
targets to quickly provision for additional storage.
The VessRAID Series of storage subsystems are designed to makewebscale computing easier for developers by offering scalable, energyefficient storage solutions for network computing. With Promises 4th generation Unified Common RAID Core and management software, scaling up to 80 bays on-the-fly is easy and affordable.

Exponential Data Growth of Unstructured Data

Managing day-to-day computing needs as well as archives of documents
and emails, digital libraries, image and audio data banks to meet user
requirements and industry regulations may easily create terabytes of
storage demand.
VessRAID is a perfect fit for unstructured data storage like general-purpose
file serving, offering cost-effective expandable storage for SMB and Entry-
Level applications and access profiles.

Backup and Restore - Online - D2D

Shrinking backup windows require rapid storage and restoration of files
and operating systems. To maximize operation, customers are switching
to disk-to-disk backups to support restoration Service Level Agreements.
VessRAID features massive capacity with flexible direct attached storage
(SAS) or IP-SAN (iSCSI) connectivity. Power management enables time and energy-efficient backups.

Video Surveillance

Moving from analog to digital, the 24/7 demands for video surveillance are
creating incredible demand for storage.
VessRAID with its low-cost expansion capabilities and SAS and IP-camera
ready iSCSI host interface is the product of choice for this application.


Graphic and video files may consume large amounts of disk space. When
jobs are complete, they are often written and stored on removable media.
With scalable capacity, VessRAID allows you to save money and prevent
data loss due to unstable removable media. Online files are also faster
to access.

GreenRAID Energy Saving Features
VessRAIDs power-scheduling feature allows the system to power-on from standby mode to run user-scheduled tasks such as backups and archives. Then as the task completes, the system goes into standby until the next scheduled task. Additionally, the 80PLUS-certified power supplies ensure the efficient use of power and minimize heat generation. VessRAID green features provide annual cost savings of up to 70% over competitive solutions.

Expandable Modularity
The 2U/12 bay and 3U/16 bay VessRAID models are fully expandable to meet your needs today and in the future. Up to four additional expansion chassis may be added to the RAID system. This provides expansion for up to 60 drives using the 2U chassis or 80 drives using the 3U chassis.
Ease of Management
One-Plug-Auto-Service (OPAS) reduces the time spent on conventional administration tasks. By simply plugging in a supported USB flash drive into VessRAIDs USB port, users are able to automatically download system service reports, as well as perform advanced functions like firmware upgrades and configuration script installation.
