Accelerating Server Cluster Performance
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 Microsoft Cluster disk performance
SuperCache II® 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 II,
SuperVolume, RamDisk and RamDisk Plus enhance overall system performance. The result is
greater rates of production, lower job times.
