Fremont, California, Dec 17, 2007 – Accusys, Inc. USA, a global leader in high-performance RAID and enterprise-class storage solution, today announce the FC-SAS and SAS-SAS redundant controllers to enable worry-free reliability while still improving the overall performance and productivity. ACS-92100 and ACS-93100 offers 4 Gb/s Fibre Channel to SAS or 3Gb/s SAS to SAS interface for the fast data transfer. Equipped with Accusys Dual Active-Active Redundant technology, and Accusys innovative OSAP™ solution, these RAID controllers provide highly dependable reliability, cost-effective flexible scalability, and user-friendly comprehensive manageability. The ACS-92100 and ACS-93100 are readily devoted to help to expand the horizon of the current and future storage markets in IO-intensive transactions, heavy-duty engineering computing, sophisticated work flow processing and media broadcasting.
Dual Active-Active Redundant Architecture
Equipped with one dedicated x4 SAS channel, ACS-92100/93100 supports dual active-active redundancy or single architecture to ensure the non-stop, flawless and reliable operation. When integrated into an enclosure of all major components are fully redundant and hot-swappable, it immediately transforms to a highly robust, incredibly fault-tolerant and failure-free enterprise-class storage system.
ACS-92100/93100 also supports Multipath I/O. It is a fault tolerant technique by creating multiple physical I/O paths between the host server system and its connected mass storage subsystem, in this case, ACS-92100/93100. This makes it possible when one controller fails or is being swapped, the operation system can route the I/O through alternative path to another controller transparently to the application or the users and avoid any data looses or video frames drops.
ACS-92100/93100's advanced modular hardware, firmware and software architecture are designed to apply on both single and dual controller environment. It is built with not only reliability, but also scalability and expandability for enterprise storage systems like, on-line e-commerce, digital media editing, application server storage, telecommunication, data archiving and more mission-critical applications.
Based on Accusys OSAP™
Accusys innovative Open Storage Application Platform (OSAP™), provides open architecture and enterprise storage solution to help to effectively build and integrate customized storage systems. With modularized firmware component, complete software resource and standard programming interface, Accusys OSAP™ is dedicate to reduce the cost, shorten the developing phase and deliver high quality for OEM partners. In contrast to the legacy approach in software development, OSAP™ provides an advanced, Linux based open architecture to allow Accusys' customers to design, develop and customize their own products. OSAP™ solution is well suited to meet the growing market demands for more creative, specialized and custom-driven products in the storage fields.
Concurrent Access to the Same Disk Group and Online Switch Preferred Controller
No separation of disk groups is required for Accusys redundant controller. Accusys redundant controller allows simultaneously accesses of two logical disks under a single disk group. Provided exclusively by Accusys redundant controller, users can now choose to create a single disk group from a large array pool while still have their storage protected by the active-active fail-over / fail-back mechanism.
Comprehensive Management
Users are allowed to manage the RAID systems from a variety of user interfaces, including command line interface (CLI) over local console and secure shell (SSH), LCD panel, and web-based graphical user interface (GUI) - RAIDGuard™. Any important or abnormal controller events are recorded and sent out through built-in emailing system to notify the administrator without any pre-installed software or agent installed. Maintenance tasks, like capacity resizing and disk scrubbing, are not only online executable, but can be pre-scheduled to perform periodically without further human interference. Non-interruptive firmware updating function seamlessly and automatically synchronized the firmware image onto both controllers in the case of redundant controllers. With all the comprehensive management utilities, little effort will be required to configure, reconfigure and monitor the array on the controller.
"Accusys redundant RAID controllers empower user's productivity and fulfills the extensive demand of delivering innovative and quality RAID storage solutions to customers," says Frank Hu, product strategy director at Accusys. "With our brand new hardware architecture, innovative OSAP™, and comprehensive management firmware, Accusys is now one more step ahead to provide the best product and service to meet the customer demands in the RAID storage markets"
