expansion enclosure (JBOD), this approach dramatically slows down CPU performance and consumes a lot of memory space as well. As a result, system performance becomes unstable. In particular when doing a data rebuild process, the system retains less than 30% of the normal computing performance. And the problem can become even more serious, leading to a system hang situation, resulting in service stoppage. Therefore, highly reliable data protection is definitely critical need for intelligent systems. Advantech’s Storage Server, which is built on an IPC-level server motherboard, employs industrial grade components and provides excellent expandability from traditional PCI to the new PCI-Express cards. Supporting a wider range of operating temperatures (0 ~ 40° C) makes it applicable to many fields. The superior data protection guarantees stable operation through an integrated LSI hardware RAID card. By adding an extra BBU battery, cache memory protection can ensure that data is not lost when a power failure occurs. Advantech’s Storage Server boasts excellent anti-vibration design and heat dissipation; it has passed complete and rigorous testing to ensure compatibility, quality, and reliability. Also, SUSIAccess software enables antivirus, backup, and remote management features. Thanks to the integration of hardware and software, Advantech’s Storage Server is a quick time-to-market solution, and allows users to save development time and costs without assembly, debugging and verification. The External Disk Array system has the advantages of unified management and resource allocation flexibility, but does mean more complex installation and configuration; this requires careful, professional assessment in order to meet the demanding requirements of intelligent systems. ● High Availability System For mission-critical applications such as medical diagnosis and treatment, factory automation, public transportation, or military defense systems, high availability is key. Although a Disk Array system is a single-controller solution, it also carries the risk of single point of failure, and can potentially cause system downtime as a result of controller failure, crash, or FW upgrade. In addition, manageability, maintenance, and system scaling should all be taken into account when assessing options. ● Fast and Efficient Data Service In order to provide excellent capabilities, the storage system not only needs hardware that supports high availability features, but also requires value-added software service to leverage system performance. The traditional, full-copy approach is safe, but occupies twice the original amount of disk space, and takes a substantial amount of time. And unless the full copy is updated regularly, the data is unrecoverable after a virus attack or hard disk crash. Yet frequent data backups result in much loss of system performance and waste storage space. Providing cost-effective data backup services is another major topic when it comes to intelligent systems. Advantech’s Disk Array solution is powered by IBM's Storwize storage system, which is a robust and trusted platform, and benefits from the company’s many years of experience in the development of storage devices and numerous successful cases.
