Solid state storage is transforming the landscape, offering performance
potentials that are orders of magnitude greater than mechanical hard disk drives
can ever deliver. As a result, there is a wide variety of Flash/SSD hardware and
software products flooding the market today. The options are wide and varied -
server-side Flash caching, hybrid storage arrays with tiers of hard disk drives,
Flash on direct-attached storage or network storage arrays - along with a myriad
of decisions begging to be made on whether the cost and complexity of migrating
to pure solid state arrays is even worthwhile. IT administrators are left
scratching their heads for a solution that will best suit their environment and
fit into their budget.
If the primary goal is to increase the performance of I/O bound applications,
consider server-side caching software. It's the least expensive option as it is
able to eliminate many of the processes, which until now, have required manual
involvement. When you are looking to improve the performance of your
infrastructure and unsure which solution is most suitable, here are some tips to
Time cost for manual configuration vs. automated?
When calculating the ROI of using solid state to accelerate applications, IT
administrators need to be sharply aware of the amount of time it takes to
manually reconfigure the storage infrastructure and modify applications.
Intelligent caching software eliminates this cost with its highly-automated
design that operates transparently, accelerating applications by up to 10x.
Because no application tuning is required, IT admins are free to focus on other
business issues and deliver new services.Multi-level caching greatly improves
the cache hit ratio
The ability to couple caching software to an operating system supercharges
cache performance by allowing the cache software to extend its policy management
to the OS DRAM cache. This design improves application performance beyond a
regular Flash cache by promoting the most critical application data to memory
speed DRAM cache, providing a significant performance boost over Flash storage
for most applications. A higher cache hit ratio means higher performance and
sustained performance due to cache disruption from other apps/processes. As the
caching software is now managing the total cache environment, it handles the
promotion of cached data into DRAM memory automatically and seamlessly. No
manual modifications are required. Data inclusion/exclusion functionality
If all of your applications carry the same importance, then accelerating
everything equally may be fine. If, on the other hand, some applications carry
more importance to the business than others, then you need caching software that
offers the ability to select specific applications for acceleration, and exclude
the others. Having a context-aware caching solution enables you to decide which
data should be included or excluded from the solid state cache based on its
business value and not simply on access frequency.
Intelligent caching software allows for faster and automated feature
With a plethora of new solid state hardware offerings arriving constantly
onto the market, IT may be distracted by compatibility concerns related to new
hardware/software choices. This issue disappears completely with intelligent
software that works with any solid state cache. Due to its tight integration
with the operating system, all hardware devices supported by the OS are
automatically supported by the caching software and as OS vendors add more
storage features, such as cache compression, and in future deduplication,
intelligent caching software is able to automatically support them.
NEVEX CacheWorks, the first policy-driven caching software available,
enables administrators to target higher performance to specific applications and
do so inexpensively with the least disruption. Its innovative approach to Flash
caching solves the storage I/O bottleneck while enabling better utilization of
existing storage infrastructures. Whether the applications are running on
virtual machines such as VMware or Microsoft Hyper-V, or on physical servers,
CacheWorks provides industry-unique control over the Windows memory cache to
create a multi-level caching solution that allows applications to exceed the
performance of running fully on Flash, for about 1/10th of the cost.
