Accelerating Application Performance in a Cluster

    With a view to assuring high availability and reliability of services to their clients, many enterprises deploy services on server clusters. Server clusters are frequently used for database servers, messaging servers, file servers, and print servers – services which place heavy demands on disk I/O.
Performance bottlenecks in server clusters   Time and again, disk I/O is a primary performance bottleneck of systems deployed in a cluster. While the storage subsystem restricts system performance, system processor and memory resources generally are underutilized. For disk-bound applications, system performance can be improved by caching the implicated storage volumes or by moving temporary data to a RAM disk.
How to accelerate disk performance   SuperCache 3® and SuperVolume® work seamlessly in conjunction with Microsoft’s Server Cluster Service (MSCS). They accelerate the read and, optionally, write performance of storage volumes, including those present on shared disks in the cluster.
    RamDisk and RamDisk Plus® feature patent-pending technology making possible the use of RAM disks by cluster applications. Temporary data files (such as database tempdb's) can be created and stored entirely in RAM, resulting in markedly improved system performance.
Boost performance by 30% - 600%   The actual increase in server throughput depends on a variety of implementation-specific factors, such as system memory bandwidth, memory bus bandwidth, amount of system memory, disk I/O bandwidth, size of the ‘hot’ data, processor type and speed, the kind of application, etc. Typical increases in server throughput vary from 30% to several hundred percent.

    By more effectively employing system processor and memory resources, SuperCache 3, SuperVolume, RamDisk and RamDisk Plus enhance overall system performance. The result is greater rates of production, lower job times.
