Getting Enterprise Features on VessRAID
Born with the field-proven enterprise RAID engine from the previous generation of Promise VTrak products, VessRAID is a robust storage system equipped with a full selection of RAID and management tools. The Intel dual-core IOP348 design inside enables SAS series to outperform existing storage arrays from competitors in an improved 15%~20% sequential read and write performance readings which is practical for mission-critical applications running on the host.
Totally Green Power
VessRAID features advance hardware design by using 80PLUS power supply and allows users to power down the system through power scheduler operation to optimize system power effectiveness and energy efficiency. Power scheduling enables the VessRAID system to do a disk-to-disk backup or restore operation on a user-scheduled basis then returns to standby mode when backup is finished, resulting in a considerable 70% cost savings annually.
One-Plug-Auto-Service (OPAS)
OPAS was designed to reduce maintenance complexity as much as possible. With a simple USB stick plug-in to the system’s USB port, it helps to shorten the turnaround time of conventional system diagnostic flow, and will come with more advanced applications like firmware upgrade, event log history, system setup restore, and array configuration scripts installation as a full service release.
Designed for Cost-Sensitive Business
Current economic conditions worldwide have caused enterprises to either cut their IT budgets or slow down their planned deployment of storage facilities. ?There is a tremendous need of cost-effective yet feature-rich storage solutions, and the Vess family is the right marketing fit at the right time.
