Technology

The A08S Cube RAID series adopts the latest Serial Attached SCSI (SAS) interface technology. It resembles SCSI in reliability but excels in performance. With the RAID 6 technology included, A08S enables continuous operation even at the time when two disk drives fail at the same time. These industry-leading technologies make A08S Cube an ideal fit for the applications requiring high bandwidth and advanced data protection.

Outlook

Besides the configuration-convertible (tower and desktop) feature inherited from the previous EonStor Cube series, A08S Cube further provides trendy choice of silver enclosure. You can enjoy the settings flexible for vertical and horizontal space allocations without sacrificing your elegant taste.

Cost-effectiveness

To save you from unnecessary expenses, we provide two models for your choice in this series. Depending on the application needs, you can select the configuration of either one or two SAS ports and power supply modules. With the flexibility, you can ensure that your limited budget is spent on what you really need.

Management

Besides the LED indicators, audible alarms, and firmware utility, we also provide the powerful management suite, SANWatch, for your easy management of the subsystem. Its intuitive GUI and robust administration features bring you simplicity in array configuration and monitoring. Whether via Intranet or Internet, the status of your subsystem is always at your fingertips.
