By adding a secondary interface to the primary array controller, Synchronix has the ability to configure the unit for either single or multiple host environments. Multi-hosting to similar systems enables server redundancy failover. If one host fails, another can take control and service applications of the failed server. Users remain active for mission critical applications. In a multi-host environment- even with servers from different suppliers - the Synchronix Storage Management System allows storage capacity to be shared between systems. By eliminating the need for entirely separate and different storage subsystems, users can benefit from a significant cost savings |
Additionally, a common storage server simplifies management and backup for systems
administrators who only need to be familiar with a single command set and user interface. The Synchronix Storage Management System features a high performance, fault tolerant architecture to satisfy large-scale, mission critical applications for open systems (UNIX and NT) environments. Synchronix has been designed to meet growing needs for a storage subsystem with high performance, flexible configurations and investment protection. It provides a scalable, continuously available, feature-rich data storage solution ideally matched for Unix and NT computing environments. Synchronix has an intuitive Graphical User Interface (GUI), redundant controllers, cross-platform and dual host support making it the perfect fit for today's changing business conditions. A modular design protects your investment by providing flexible growth options to keep pace with your changing business requirements. |

Maximum Fault Tolerant Design | ||||||||||||||||||||||||
All active components, including disk drives, power supplies, fans and system controllers are fully redundant and hot swappable, meaning that the system will remain on-line even in the unlikely event of multiple component failures. If Synchronix detects a power failure in either the power supplies or an external source, it will automatically change caching to a write-through mode and flush all cached data to the disks. | The dual controllers automatically monitor and maintain coherency between both sets of cache, allowing one controller to take over if the other one fails. Used with a commercially marketed High Availability Server Failover Software, Synchronix supports multiple host initiation in the event of a server failure. | |||||||||||||||||||||||
Exceptional Cache Management Secures Superior Performance RAID level 5 implementations typically cause severe write performance degradation in many applications that benefit from high availability. However, with ECCS' write-back technique, Synchronix optimizes random read/write operations. Synchronix achieves RAID Level 5 read/write performance that is typically three times faster than other products in its class. With write-back cache, the write request is acknowledges to the host as soon as the data is in cache and the actual disk update can occur at a later time. Performance greatly improves because the application does not have to wait for write completion. Synchronix utilizes an exclusive Data Consistency Check. This Data Consistency Check ensures that data is properly written to disk. The non-segmented, adaptive cache is highly user configurable via the GUI. This superior cache management system allows users to obtain maximum performance without I/O bottlenecks common to other implementations. To further protect against data loss, ECCS offers an intelligent UPS as an option. The UPS interfaces through one of the two Synchronix serial ports. In the event of a power failure, Synchronix can flush the cache to storage and orchestrate a graceful power-down. With ECCS' write gathering technique, Synchronix can update multiple, continuously stored data blocks on a disk with a single write operation, thereby reducing the number of separate I/O transactions.

The Synchronix Storage Management System also uses a read ahead optimization feature that enhances sequential read operations. By monitoring data access requests for sequential patterns, Synchronix can begin filling its read cache with data from all drives in a strip, in anticipation of its actual need, thereby minimizing wait times. |

Performance The Synchronix controller supports Tagged Command Queuing to the disk drives, with up to 255 Tags. This means that 255 requests can simultaneously be processed over 16 logical disk drive volumes. For RAID 1 and 10 volumes, Synchronix further increases performance by using Inverse MirroringTM to minimize disk drive seek times. Scalable Features Synchronix uses 16MB SIMMS for system cache allowing a total of 224MB of cache per controller. This gives you the ability to configure Synchronix to the optimum combination of cost and performance |
